“Exercise tells the muscles to cleanse and reset”

July 21, 2026 by usatoday24

The effects of physical exercise for older people They are more than proven. It helps them improve their cardiovascular health, improves mobility, reduces fractures and, in general, provides a long list of benefits. It is good at all stages of life, but when we get older it becomes essential. However, as well studied as this is, until recently it was unclear why it is so beneficial. Knowing the reason is necessary, as it can help squeeze those advantages even more. Now, a team of scientists from Duke-NUS Medical School, in collaboration with Cardiff University and Singapore General Hospital, has taken a big step in this directionby discovering the molecular pathways that cause both the deterioration of muscle health in advanced ages and the benefits of physical exercise for older people. Molecular pathways that suffer. This study is supported by previous research, which already pointed to the possible involvement of the mTORC1 pathway, involved in the regulation of the synthesis and elimination of muscle proteins. This pathway must maintain a balance between the synthesis of new proteins and the elimination of those that are damaged. However, it has been seen that, as we get older, this pathway becomes deregulated, tipping the balance towards the synthesis of new proteins. Damaged proteins that should normally be removed accumulate, causing stress on muscle cells and leading to a progressive loss of strength. This pathway, in turn, is regulated by another, called DEAF 1. As these scientists have seen, when its activity increases, the expression of genes in the mTORC1 pathway increases, causing this imbalance towards protein synthesis. Furthermore, what these scientists saw in experiments with fruit flies and mice is that the activity of DEAF 1 is regulated by the activity of a group of proteins that also exist in humans: FOXOs. They keep them in line. The problem is that FOXO activity decreases with age, giving free rein to DEAF 1 and, with it, an imbalance in the synthesis and elimination of muscle proteins. The role of physical exercise in older people. In their study, these scientists have seen that physical exercise reactivates FOXOs proteins. Therefore, physical exercise in older people aid to maintain balance in the synthesis and elimination of muscle proteins, improving muscle mass and increasing the benefits associated with it. Also stem cells. DEAF 1 does not influence muscles only by deregulating protein synthesis and elimination. It is also related to the synthesis of muscle stem cells. This normally decreases with age. Therefore, finding ways to maintain good activity levels is key. Physical exercise in older people also helps in that sense. It is not the same for everyone. In their study, these scientists have seen that, unfortunately, physical exercise does not always seem to be a good tool alone. There are people for whom it is enough, while others must resort to additional strategies to improve their health. This is the path through which they must continue studying. Not just for seniors. This study is not only aimed at studying the benefits of physical exercise in older people. Its authors believe that it can also be useful for patients who have lost muscle mass due to recovering from surgery, a fall, or diseases such as cancer. Be that as it may, the initial key is to understand the mechanisms that reduce the muscle health of older people. According to one of the authors of the studyPriscillia Choy Sze Mun, “physical exercise tells the muscles to cleanse and reset.” Logically, we will have to study more. To begin with, it would be necessary to verify that, no matter how much the mechanisms are shared, what has been seen in mice can be extrapolated to humans. If so, we would have key knowledge to improve physical exercise programs for older people. Knowledge is power and, in science, knowing the whys of things is very powerful.

“A sedentary lifestyle is an independent risk factor and it is not enough to ‘compensate’ for it with specific exercise”

July 6, 2026 by usatoday24

There are many people passing by much of her day glued to a chairin many cases because they are working, traveling by car or resting on the couch, with a sedentary lifestyle being a true routine in the lives of many people. Until now we knew that it was harmful, but now science has put exact numbers on how an uninterrupted sedentary lifestyle influences our health, and the most important thing is that it has been seen that it does not help to compensate for it. With a watch. A new study published in PLOS analyzed data from 91,292 people from the UK Bank, and unlike other epidemiological studies that rely on questionnaires filled out by the participants themselves, here they used accelerometry. That is, for years they have monitored the physical movement of all these people thanks to activity sensors on the wrist. After an average follow-up of 12.38 years, the researchers not only measured total inactivity time, but how it was distributed throughout the day. And that’s where the real enemy to our health comes in, which are blocks of uninterrupted time. You have to get up. The central finding of the study does not penalize the simple act of sitting so much, but rather doing it continuously. The researchers concluded that each additional hour of prolonged sedentary behavior, understood as periods of 30 minutes or more without getting up at any time, is associated with a 10% increase in the risk of cancer mortality. That is to say, spending long work days without moving at all is not free in the long term. The solution. Fortunately, the results also show that the human body is incredibly grateful when we break that stasis. Using statistical time substitution models, the study calculated what happens when we swap prolonged periods in the chair for different “doses” of daily physical activity. To give an example, replacing one hour a day of prolonged sedentary lifestyle with low-intensity activities such as walking at a normal pace or doing housework reduces the risk by 12%. But if we go further, changing just 30 minutes of uninterrupted sedentary lifestyle for moderate physical activity reduces the risk by 8%. The most important thing. The most efficient substitution has been found to require very little time, as swapping sedentary time for just five minutes a day of vigorous physical activity reduces the risk of cancer mortality by a staggering 22%. The golden rule. As is usual when analyzing medical literature, and as the authors and independent experts themselves emphasize, we must read the fine print. As it is an observational study, the data show a strong statistical association, but the design itself cannot demonstrate strict and absolute causality, leaving it exposed to certain biases, such as the UK Biobank volunteers usually having a healthier baseline profile than the population average. However, this research does not arrive in a vacuum since it is tremendously consistent with previous scientific evidence and gives robustness to what we already suspected. In 2022, a meta-analysis and umbrella review already warned about the strength of the relationship between a sedentary lifestyle and oncological risk. And at a closer level, a study by the Carlos III Health Institute in 2024 confirmed in the Spanish population that replacing just one hour a week of sitting time with physical activity managed to reduce general mortality. The experts. Nabil Djouder, head of the Group of Growth Factors, Nutrients and Cancer of the National Cancer Research Center (CNIO) in statement to SMC pointed out that this study “reinforces the idea that sedentary behavior is an independent risk factor and that it is not enough to ‘compensate’ for it with specific exercise.” Images | Vitaly Gariev In Xataka | Spending hours sitting in front of the screen is not only destroying your body, it is also changing your personality

“Exercise cannot be optional for those taking Ozempic”

June 20, 2026 by usatoday24

The classic and generally effective recipe for losing weight is summarized in two combined measures: taking care of your diet and increasing physical exercise to tip the calorie balance until it becomes negative. That is the canonical formula, but the arrival of drugs like Ozempic, wegovy o Mounjaro has turned it upside down. So much so that we are even giving up those basics. Thus, a paradoxical fact occurs: there are people losing weight (with Ozempic and similar) and exercising less. This indicates the breakdown of a healthy metabolic virtuous circle: losing weight invites us to move more, which in turn promotes weight loss. Thinner. Less athletes. a study presented at the prestigious annual meeting of the Endocrine Society (ENDO 2026) evidence that adults with obesity who lost weight with GLP-1 receptor agonist drugs have significantly reduced their physical activity. That is, after losing weight they exercise less. More specifically: when analyzing 753 patients with obesity and the data from their respective activity bracelets, it was discovered that daily steps fell from 5,047 to 4,487 (560 fewer steps) and the time of moderate or intense exercise fell from 27.9 to 22.2 minutes per day. Those who reduced their activity the most were men and those people with joint or muscle pain. Why is it important. Because these Ozempic-type drugs are not limited to reducing body fat, but can also contribute to losing lean muscle mass: a body composition analysis of the STEP 1 trial points out that weight loss with semaglutide corresponds to a reduction in lean mass of up to 40% of the total weight lost. That is why physical activity is essential to maintain strength and general health. If these people move less, the problem worsens. From a public health perspective, the need to offer explicit exercise prescription to the millions of people who take these drugs is imperative. As explains Dr. Sajana Maharjanlead author of the study: “The findings of our study reinforce the idea that exercise cannot be optional for people taking these medications. Specific interventions that encourage physical activity along with obesity medication are needed.” Context. GLP-1 receptor agonist drugs act in the brain by reducing the feeling of hunger and, as a consequence, caloric intake. What was not clear until now is its effect on the desire to move. There is previous animal studies who had already suggested that GLP-1 can reduce locomotor activity by acting on the dopaminergic reward system, for example, in micebut this work transfers it to humans with real information. Until now, studies on physical activity in patients treated with Ozempic and similar drugs have used questionnaires that people fill out alone, which opens the door to overestimation of actual exercise. However, for this work They have combined real data from Fitbit with the NIH All of Us program. In detail. Of the 1,950 patients who started treatment, only 753 had sufficient fitness tracker data for analysis. The sample presented a relevant heterogeneous case mix: 81.9% had musculoskeletal pain, 67.3% had hypertension and 48.1% had type 2 diabetes, which adds an important bias since they are complex patients with reasons to move little, with or without the drug. 560 fewer steps may not seem like much compared to the recommended daily total (friendly reminder: They are not the mythical 10,000 steps) of the WHO, but it has its importance: if the minimum ideal around 7,000 – 8,000 steps daily to obtain cardiovascular benefit and these patients are already below, any additional reduction takes them even further away from the minimum health goals. Yes, but. The study has some important limitations. To begin with, there is no control group (obese patients who did not take this type of drug), so although this is an important clue, it cannot be said with certainty that the drop in activity is caused by the drug and not another factor. Besides, the sample is heavily biased towards women (almost 8 out of 10) and towards people who already used Fitbit regularly, who do not represent all patients with obesity.

Science already knows what is the best “gasoline” to create new neurons: physical exercise

March 7, 2026 by usatoday24

We have always known that playing sports is good for the heart and also the muscles, but neuroscience is showing us that running shoes are, literally, the best tool to sculpt our brain. This is how I put it on the table the neuroscientist José Luis Trejowhich pointed out that physical exercise acts as a true “gasoline” for neurogenesis in the hippocampus adult to make us more ‘smart’ and also tend less towards depression. Neuron factory. Until a few decades ago, it was believed that you were born with a certain number of neurons and that, from there, they could only be lost. But today we know that this is completely false, since the generation of new neurons has already been demonstrated, and it occurs mainly in a region of the brain that is key to learning, memory and emotions, such as the hippocampus. The exercise. Here the different studies were focused on how this generation of neurons can be enhanced, and moderate aerobic exercise is the main switch to turn on the neuronal factory. How it works. The specific exercise and also extended over time, it raises the BDNF segregationwhich is the brain-derived neurotrophic factor, and also the VEGFwhich is vascular endothelial growth factor. Two proteins that act as ‘fertilizer’ in the brain to promote neuronal plasticity and the formation of new blood vessels to nourish all these new cells that appear in the brain. There are results. Studies done in humans themselves measured cerebral blood volume using functional magnetic resonance imaging, and here they could see that there is a real increase in the volume of the hippocampus and there are also improvements in spatial memory and cognition, which is essential from certain ages onwards. And it is no wonder, because there are studies that suggest that constant exercise increases total hippocampal volume, being a first-level strategy against cognitive declineand therefore acts as a shield against Alzheimer’s. Antidepressant. In addition to being a shield against Alzheimer’s, it can also reduce the symptoms of anxiety and depression, overcoming the effects of antidepressants in some patients. However, we must have common sense with the ‘dose’ of exercise we do. And a perpetual sedentary lifestyle is toxic, since sitting atrophies all brain capacities, but excess is destructive because extreme intensity training without rest generates a peak of stress in the body that completely cancels out the neurogenic benefits. That is, doing a lot of exercise at maximum capacity can block the creation of new neurons. It is hereditary. But if making new neurons is not enough to join the gym, science suggests that it can be transmitted to children thanks to epigenetics. In 2019, a study published in PNAS demonstrated that paternal exercise increases neurogenesis and mitochondrial activity in offspring, even if the latter are sedentary. But in 2024 went furtherseeing that these neuroplastic effects can be inherited up to two generations later. The dose. In summary, neuroscience suggests that doing 45-60 minutes a day of moderate aerobic activity can bring us great benefits over spending uninterrupted hours in the chair. Without a doubt, memory, mood and hippocampal volume will be truly grateful. Images | Chander R Bhautik Patel In Xataka | Scientists have connected 200,000 human neurons to a chip.

the minimum dose of exercise that science points to changing the health of those over 60 years of age

February 8, 2026 by usatoday24

In the 1980s, gerontologist Robert N. Butler launched a phrase that has become in a mantra of modern medicine: “if exercise and physical activity could be packaged as a pill it would be the most widely prescribed and beneficial medication for the population.” Forty years later, science has stopped treating that phrase as a metaphor and turned it into a mathematical calculation. The ROI of the force. Until now, we knew that sport was healthy, but data on its direct clinical profitability were lacking. The GENUD research group, led by José Antonio Casajús, published in Experimental Gerontology at the end of 2025 one of the strongest evidence to date. The essay, carried out with 123 people over 80 years oldprescribed a treatment of three weekly supervised exercise sessions for six months. The clinical results were clear: improvements in functional capacity, reduction in frailty and increase in quality of life. But the data that has aroused the interest of health managers is economic. The conclusion here was that while the cost of the intervention was only 164 euros per person, The savings to the system exceeded 1,000 euros. The clinical squat. If exercise is the ideal drug, clinical evidence points to the squat being the most important active ingredient here. Many studies have precisely validated this movement, which can mean the world to some people, not as a gym exercise but as a diagnostic and treatment tool. Biomechanics is key. Why is the squat so important to medicine? First of all because it is an exercise that demands more on the hip extensorsvital for an elderly person to be able to get up from a chair or bed without help. But in addition, it also activates the quadriceps and plantar flexors more. At the metabolic and cardiovascular level, the impact is systemic. The venous compression that occurs during the squat increases venous return and cardiac output, acting as a natural pump that combats orthostatic hypotension. Even in post-stroke patients, fast squats have been shown to activate the injured rectus femoris, correcting asymmetries and improving postural control. How long. You don’t have to work hard, since a recent study showed that a program of just one minute a day, that is, about thirty seconds of squats and thirty seconds of push-ups, is enough. This is something that was seen with prescription by primary care physicians, improving physical performance in patients over 60 years of age with excellent adherence at 24 weeks. Anti-cancer effect. Beyond the effect on adults, important implications of physical exercises in pediatric cancer have also been seen. This was evidenced by Carmen Fiuza-Luces, from the Physical Exercise and Pediatric Cancer group, who directs the “La Aceleradora” project of the Unoentrecienmil Foundation. And contrary to the belief of having “absolute rest” when you have cancer, the evidence shows that exercise during treatment of pediatric solid tumors It achieves what no drug can. For example, it reduces the side effects of chemotherapy, protects the heart from the toxicity of the treatment or prevents atrophy in sick children. The problem is not the drug. The problem with prescribing exercise in consultation is lack of knowledge about the ‘dose’ that should be given. Just as a doctor does not say ‘take an antibiotic’ without a clear duration and frequency, the same thing happens with sports. You can’t say ‘do sports’. In these cases, exercise requires a dose in the form of frequency and duration, the intensity that must be personalized to each patient and, above all, monitoring with adaptation to the patient’s pathology. Looking for the front door. The Health and Sports Working Group of the Collegiate Medical Organization, coordinated by José Ramón Pallás, is pushing for integrate exercise into the National Health System as a therapy equivalent to drugs. The goal is for the “3 sets of 10 squats” recipe to be as official and binding as any blood pressure pill. In this way, science has done the numbers and all that remains is for the administration to make a move.

The “sweet spot” of exercise according to science is 30 minutes

January 18, 2026 by usatoday24

For many years the goal of taking 10,000 steps per day has been the universal health mantrarepeating itself in medical consultations or being predefined in smart watches that monitor physical activity. But this mantra is evolving thanks to the latest evidence we know, since it is not just about how many steps you take, but how they occur. A sweet spot. For this science has identified the ideal when doing physical activity: 30 minutes of brisk walking (walk at a brisk pace) at a constant speed of 5 km/h. This habit is not only more efficient than taking random walks, but Delivers metabolic benefits previously only attributed to high-intensity gym workouts. An important threshold. The fact of having to exceed a speed of 5 km/h It is crucial when walking with the purpose of improving cardiovascular health. And for a walk to be considered “moderate intensity exercise”, it is not enough to move. Science in this case considers that there is a critical threshold that we must keep in mind when recommending doing the exercise: 100 steps per minute. That is what translates into this approximate speed of 5 km/h. And it is not something random, since it has been seen that at this speed there is a significant reduction in the glycosylated hemoglobin (HbA1c) related to diabetes and systolic blood pressure (known as ‘high’). The secret is continuity. One of the most powerful findings from the studies It is precisely in the amount of time we invest in sport. And there is a big difference between continuous 30-minute sessions, in which we only walk, versus accumulated sessions, where we walk for five minutes and then stop continuing. In this case, the continuous 30-minute session is what has been found to be best for reducing insulin sensitivity, improving resistance, hip circumference, and also exercise adherence. And although it is good to move 5 minutes every hour to avoid a sedentary lifestyle, the reality is that it is best to dedicate only half an hour a day continuously. A shield against aging. For the middle-aged population, walking is literally life insurance. Different studies suggest that walking at 5 km/h for 30 minutes a day, for five days a week, helps reduce the risk of stroke (due to lowering blood pressure). But in addition to this, it also combats anxiety and stress, which is undoubtedly one of the big problems we have in today’s society with the stress hormone triggered and doing a lot of damage to our body. With all this, the increase in life expectancy is quite substantial compared to more sedentary people. Without forgetting strength exercises. Although walking is essential, we must not forget our muscles either. It is very important when you reach middle age do not neglect the development and maintenance of muscle, since there are many studies that suggest that it delays biological aging and even offers cognitive benefits such as protection against neurodegenerative diseases. In this way, in order to reach old age in optimal conditions, we must not forget to be mobile to reduce metabolic syndrome, but also to be attentive to our muscles.

The new obsession in gyms is also a clue about the future of the exercise

June 24, 2025 by usatoday24

It is the New Fitness World Fever: competitions that carry exercises and, therefore, very specific training. By comparison, although these exercises settle their bases in traditional training, make crossfit or calisthenics They look outdated or rough. A mixture of unique elements (competition, aesthetics and that philosophy of overcoming and stoicism so fashionable in the latest generation gyms) has become Hyrox In a phenomenon. We analyze Some of your keys. What is it. It is a competition that combines 8 kilometers of career with 8 functional exercises of strength and resistance. The exercises are always the same and include: skiing machine, thrust and drag of sleds, Burpees With long jumps, rowing, weight transport, strides with sandbags and medicinal ball throw. That is, a devastating mixture (but with exercises available to anyone) that combines strength, resistance and general athletic capacity. Worldwide success. Born in 2017 in Germany, in recent years he has experienced a great impulse (globally, more than 650,000 athletes train for competitions, and in 2025 more than 80 global careers are held in more than 30 countries and 85 cities). It currently has a wide margin of future growth: for example, it has just reached areas such as Canada, Australia and the Middle East, and the World Championships of discipline. Spain wants Hyrox. Spain is one of its largest areas of growth. The last edition, in Bilbao, congregated More than 8,000 competitors. In Malaga 2025 11,000 athletes from 40 countries participated, while in Hyrox Barcelona 2025 13,000 athletes were registered and 10,000 finished. In the 2024-2025 season, the discipline exceeded the 40,000 athletes registered in Spainconsolidating the country as one of the European referents in this discipline. The number of participants has grown by 1,900% since the first major national event in 2021, when 2,000 athletes were recorded. The secret of his fame. Why do you like a competition so much that is essentially a traditional fitness vitamin version? His hybrid nature It has a lot to do: the demanding of the competitions forces athletes to prepare not only force, with lifting and movements of large weights, but also resistance, with those eight kilometers that must be traveled between evidence. That makes it a Very complete and varied trainingand where no discipline should not be put aside. And also, without great technical demands: everyone can push a sled. On the other hand, the competition allows group or couples categories, which makes it more affordable. Class pride. Hyrox is one Registered trademarklike so many others associated with fitness. From the very Crossfit itself, which is not a generic word but a brand associated with official competitions and training, the popular Zumba, which has unleashed a real plague of imitators (in the end, it is the old man Gym-Jazz eighties in steroids). All this going through competitions that were ahead of Hyrox, such as Spartan Race or Ironman, and training systems such as F45 Training or Orangetheory Fitness. What does all this mean? That to train and compete in Hyrox you have to pay the fee that Hyrox architects decide to pay. This leads to official gyms and competitions of considerable price (the minimum cost of a career is usually around 70 euros), and by the hand, to the transformation of training into a piece of exhibition of good economic health that distance to Hyrox of formats (not registered) such as calistenia, which can be trained outdoors. Hyrox not only allows to show off a healthy way of life but also a well oxygenated portfolio. Training as Lifestyle. Linked to this last aspect, we have sport as an exhibition mode of a way of life, also vent, to which Hyrox international competitions help, in countries like Berlin or Rome. A circumstance that allows “healthy tourism”: travel to compete, and without neglecting what affirms Álvaro Taracena, CEO of the brand in Spain: “Nobody here looks at you badly for lifting less weight (…) to do something more dynamic, in the end you make friends with whom take“ Hyrox for Influencers. At a time when absolutely everything has to be Instagrameable To succeed, Hyrox has the elements to do so: It is completely training gamified and aimed at a specific objective (compete and improve brands in competitions, no abstractions such as “health”). His name resulton makes him Easy to google and labeland generates a feeling of belonging to a group. And lo Accessible competitions (With team modalities, without time limits) open the doors to anyone looking for more than sweating two days a week without a clear goal. As a business studied to the millimeter, of course, it is one of the elderly that has seen modern fitness Header | Hyrox In Xataka | Marathons are so extreme that our brain makes drastic decisions, how to consume itself

There are countries that do not exercise as they should, and this map exposes the most sedentary

May 4, 2025 by usatoday24

Change Life habits and putting in shape is one of the most common purposes when the year begins. So much that there are studies that have proposed to analyze How to meet that goal Without discouraging ourselves because, for many people, putting on form implies “from zero”. The reason is that many do not perform the physical activity necessary to remain in good shape, which implies a risk for both physical and mental health. And on this map of Visual Capitalist We can see what are those countries in which people do not do the necessary exercise. The recommendation. The World Health Organization recommends that adults dedicate 150 minutes a week, at least, aerobic physical intensity activities. This includes walking -which is increasingly uncovered as A highly recommended exercise-, but also swim, jog or ride a bike. And these 150 weekly minutes must be complemented with 75 minutes of activities such as peso lifting for Strengthen both muscles and joints. WHO also says that any physical activity is better than any. The exercise not only keeps us healthier, but also contributes to a Best Mental Healtha better humor and a better resistance to diseases. The problem is that, as a study published in The Lancet Global Health It has demonstrated, much of the population does not move as much as it should. The study. The article explores and collects the data related to the physical activity reported by adults in different population surveys. Through the analysis of 507 surveys in 163 countries with a total of 5.7 million participants, researchers have been able to estimate the prevalence of insufficient physical activity between 2000 and 2022. The data. They are not good. According to their interpretations, in 2022, 31.3% of people worldwide performed insufficient physical activity, not reaching those minimal recommendations of WHO. In 2010, that figure was 26.4% and in 2000 it stood at 23.4%. We see, therefore, a bullish trend, but also a significant increase between the last decade and the previous one. By countries. The map prepared by Visual Capitalist collects this data and reinterprets the maps published in the study itself. In some cases, these data are devastating. In much of the American continent, two thirds of the population do not meet those guidelines marked by WHO. There are exceptions like Mexico, but the population is also close to that inactivity figure. In Europe, the situation is quite diverse. Spain has 22%of the population that performs insufficient physical activity, France 23%, Germany 12%, Austria 20%and Belgium 25%. However, there are cases such as Poland with 35% inactivity, Italy with a striking 40% and Portugal with 52%. Dramas. They are striking data, but together, the worst part is taken by the Middle East and part of Asia. United Arab Emirates is the worst country in this regard, according to the analysis, with 66% of its population performing insufficient physical activity. Kuwait is not very far with 63% and Lebanon stays at 59%. It is a trend in the area, with Qatar and its 54% inactivity, or Iraq and Saudi Arabia with 52%. Looking at Asia, South Korea is not much better, with 58% of the population that does not move what should, 52% of the Japanese are also more sedentary of the account and we see that India has an index of 49%. Japan’s case is curious, since it is a country that is proud of its longevity and of the exercise programs for the elderly. More and less aligned countries with the objectives for 2030. The more azul, the better Social inequalities. Speaking of age, it is something that also plays a role in these data. In this period of analysis, insufficient physical activity increased between those over 60, regardless of the sixth and the region to which they belong. But we also see many countries with light colors that represent that they are doing the recommended activity, but as we used to have meme in Xataka, it has a trick. Some of them are in Europe as Finland (10%), Netherlands (9%) and Sweden (8%), among others, but the vast majority are in the Sub -Saharan Africa area. And it is not that they want to train than the rest of the world, but that it is a very active population due to economic reasons since a greater proportion of population in poorest countries is used in tasks such as agriculture or manual works, something that counts for movement statistics. Because these social inequalities, in the end, are represented in a very varied arc of situations, and in the study itself we can see that the activity index barely varies between people with low income, but that when life is somewhat more accommodated, Sedentary lifestyle also increases. And the conclusion of the study is that, in the end, almost a third of adults around the world do not meet the recommended levels of physical activity and it would be a good idea that policies were strengthened to foster that exercise.

Of course, better combine it with exercise

April 7, 2025 by usatoday24

Intermittent fasting has become a very popular strategy among those who seek to lose weight or, at least, keep their weight under control. However, as with most diets, clearly establish their effectiveness It is often difficult Due to the complexity of our food, our metabolism and, in general, of our own body. New tests. Now a study has contributed New tests of the efficacy of intermittent fasting. Tests that, yes, are limited to the context in which this diet is combined with regular exercise. The team studied a diet with a meal window limited at eight hours (inversely, 16 hours of fast) and observed that in this way a loss of “small but significant” fat was possible. All this without sacrificing muscle mass, a detail highlighted by the team. “We observed that (a greater reduction of fat was achieved) and a lower percentage of body mass over time, when healthy adults followed (a regime) both of exercise and temporarily restricted dietcompared to those who only exercised for at least four weeks ”, explained in a press release Nadeja Wijayatunga, co -author of the study. 15 studies. In its analysis, the team carried out a systematic review of scientific literature that studied the impacts of this type of interventions. Thus, 15 recent works found in which the combined effect of intermittent fasting and exercise on our weight was analyzed. From the results described in these studies, the team carried out a meta -analysis, that is, a quantitative study to estimate an average effect. In its study study, the team observed a statistically significant change, a loss of body mass that was not associated with a loss of muscle mass. The analysis also pointed out that variables such as age, body mass index, or the type of exercise with which the diet was accompanied, among other factors, did not affect this result. The details of this work were published In an article In the magazine International Journal of Obesity. Easier than counting calories. Perhaps because it is easier to tell the hours than to tell the calories, the intermittent fast has become the favorite option of many. But sometimes the easy thing is not the most effective and we already know at this point that miracle diets do not exist. That is why putting the virtues and limits of this type of strategies to the test. It should be noted that there are various forms of intermittent fasting, depending on the frequency with which we fast and the time fraction of the day we dedicate to fasting and food. The success or failure of these strategies can also depend on other factors such as having a varied diet in the hours we dedicate to food and even factors that might seem irrelevant like our dream.
