Morning workouts

This Is the Best Time of Day to Work Out, According to Science

finding time to exercise can be challenging, and the most important thing is to squeeze in any amount of it whenever you can. But if you want to optimize your workouts to get the widest range of benefits, you might want to try exercising in the morning.

Here’s what the science says about the best time of day to exercise — and what to expect if you opt for later workouts.

Morning workouts have an edge

Working out in the morning — especially on an empty stomach — is the best way to burn stored fat, making it ideal for weight loss. That’s largely because the body’s hormonal composition in the morning is set up to support that goal, says Anthony Hackney, a professor in the department of exercise and sport science at the University of North Carolina Chapel Hill.

“In the early morning hours, you have a hormonal profile that would predispose you to better metabolism of fat,” Hackney says. People naturally have elevated levels of cortisol and growth hormone in the morning—both of which are involved in metabolism—so you’ll “draw more of your energy from your fat reserves,” Hackney says. That can potentially help with weight loss. Research also suggests that morning exercisers may have less of an appetite throughout the day, which could also help protect them from putting on pounds.

The Roman physician Galen is considered a forefather of the study of anatomy and medicine. Writing during the second century, he emphasized the need for exercise every day and throughout life — not just for the prevention of disease, but for the promotion of proper digestive health, organ function, and general well-being.

According to the medical historian Jack Berryman, Galen recommended exercise that was vigorous enough to increase the breath, but not so intense that it left a person in pain. Like many of the great Greek thinkers who came before him, Galen prized “moderation in all things,” and that extended to exercise.

Older A“,
Adults (65 years and over) 
• Older adults should participate in daily physical activity to gain health benefits, including maintenance of good physical and mental health, wellbeing, and social functioning. Some physical activity is better than none: even light activity brings some health benefits compared to being sedentary, while more daily physical activity provides greater health and social benefits.

• Older adults should maintain or improve their physical function by undertaking activities aimed at improving or maintaining muscle strength, balance and flexibility on at least two days a week. These could be combined with sessions involving moderate aerobic activity or could be additional sessions aimed specifically at these components of fitness.

• Each week older adults should aim to accumulate 150 minutes (two and a half hours) of moderate intensity aerobic activity, building up gradually from current levels. Those who are already regularly active can achieve these benefits through 75 minutes of vigorous intensity activity, or a combination of moderate and vigorous activity, to achieve greater benefits. Weight-bearing activities which create an impact through the body help to maintain bone health.

• Older adults should break up prolonged periods of being sedentary with light activity when physically possible, or at least with standing, as this has distinct health benefits for older people. 10 UK Chief Medical Officers' Physical Activity Guidelin

Liberada pelos músculos, a irisina melhora o funcionamento dos neurônios e reduz o esquecimento em roedores com enfermidade semelhante ao Alzheimer

Fazer exercícios físicos regularmente melhora o desempenho da memória e parece retardar a ocorrência de esquecimentos nos estágios iniciais da doença de Alzheimer, enfermidade que atinge cerca de 35 milhões de pessoas no mundo e é marcada por perda de memória e redução da capacidade de planejamento. Uma longa sequência de experimentos realizados com células, animais e também seres humanos pelos grupos da neurocientista Fernanda De Felice e do bioquímico Sergio Teixeira Ferreira ajuda agora a explicar por quê. Em um artigo publicado on-line hoje (7/1) na revista Nature Medicine, os pesquisadores brasileiros, ambos professores da Universidade Federal do Rio de Janeiro (UFRJ), apresentam um conjunto robusto de evidências de que o hormônio irisina, liberado pelos músculos durante a atividade física, é importante para a formação da memória e a proteção dos neurônios dos efeitos tóxicos de compostos associados à origem do Alzheimer.

An Anti-Aging Pill? Think Twice

The diabetes drug metformin, sometimes taken to slow aging, may blunt the health benefits of exercise.

By Gretchen Reynolds

“Doctors are very cognizant of drug-drug interactions,” he says. “It’s time we consider drug-and-exercise interactions, too.”

A popular diabetes drug sometimes taken to slow aging may diminish some of the expected health benefits of aerobic exercise in healthy older adults, according to a new report. The drug, metformin, can blunt certain physical changes from exercise that normally help people to age well./.../

Children under 5: exercise...

More exercise, less screen time for children under 5  Share Tweet Forward Share WHO has released new guidelines on physical activity, sedentary behavior and sleep for children under 5 years of age. The new guidelines set, for the first time, how long very young children should sit watching screens, called ‘sedentary screen time’. Quality sedentary time young children spend in interactive non-screen-based activities with a caregiver is very important for child development. Improving physical activity, reducing sedentary time, ensuring quality sleep in young children will improve their physical, mental health and wellbeing. It will also help to prevent childhood obesity and associated diseases later in life.

Highlights Of The 2018 Physical Activity Guidelines for Americans, 2nd Edition

Abstract

Importance  Approximately 80% of US adults and adolescents are insufficiently active. Physical activity fosters normal growth and development and can make people feel, function, and sleep better and reduce risk of many chronic diseases.

Objective  To summarize key guidelines in the Physical Activity Guidelines for Americans, 2nd edition (PAG).

Process and Evidence Synthesis  The 2018 Physical Activity Guidelines Advisory Committee conducted a systematic review of the science supporting physical activity and health. The committee addressed 38 questions and 104 subquestions and graded the evidence based on consistency and quality of the research. Evidence graded as strong or moderate was the basis of the key guidelines. The Department of Health and Human Services (HHS) based the PAG on the 2018 Physical Activity Guidelines Advisory Committee Scientific Report.

Recommendations  The PAG provides information and guidance on the types and amounts of physical activity to improve a variety of health outcomes for multiple population groups. Preschool-aged children (3 through 5 years) should be physically active throughout the day to enhance growth and development. Children and adolescents aged 6 through 17 years should do 60 minutes or more of moderate-to-vigorous physical activity daily. Adults should do at least 150 minutes to 300 minutes a week of moderate-intensity, or 75 minutes to 150 minutes a week of vigorous-intensity aerobic physical activity, or an equivalent combination of moderate- and vigorous-intensity aerobic activity. They should also do muscle-strengthening activities on 2 or more days a week. Older adults should do multicomponent physical activity that includes balance training as well as aerobic and muscle-strengthening activities. Pregnant and postpartum women should do at least 150 minutes of moderate-intensity aerobic activity a week. Adults with chronic conditions or disabilities, who are able, should follow the key guidelines for adults and do both aerobic and muscle-strengthening activities. Recommendations emphasize that moving more and sitting less will benefit nearly everyone. Individuals performing the least physical activity benefit most by even modest increases in moderate-to-vigorous physical activity. Additional benefits occur with more physical activity. Both aerobic and muscle-strengthening physical activity are beneficial.

Conclusions and Relevance  The Physical Activity Guidelines for Americans, 2nd edition, provides information and guidance on the types and amounts of physical activity that provide substantial health benefits. Health professionals and policy makers should facilitate awareness of the guidelines and promote the health benefits of physical activity and support efforts to implement programs, practices, and policies to facilitate increased physical activity and to improve the health of the US population.
