With help from 2,000 Framingham Heart Study participants, BU researchers studied how much being sedentary, walking, and routine exercise impacts fitness.
When we think about the most important actions that we can take to protect our health, we usually consider behaviors such as partaking in regular physical activity or eating a nutritious diet. Yet, an often-overlooked aspect of maintaining a healthy lifestyle is sleep. Sleep has serious implications for your physical and mental health. Adequate sleep will help you recover from exercise, enable your immune system to fight off pathogens and increase cognitive performance. In fact, to highlight its importance to health, the number of hours that people sleep is included as an indicator in the annual ACSM American Fitness Index (Fitness Index).
Two studies suggest the sweet spot for longevity lies around 7,000 to 8,000 daily steps or about 30 to 45 minutes of exercise most days.
The health benefits of aerobic exercise cannot be over emphasized in preventing cardiometabolic diseases. Exercise interventions are also commonly proposed to help lose weight and seem efficacious for weight loss maintenance. In the U.S., 30 minutes of moderate-intensity exercise per day for five days per week (150 minutes total per week) is recommended for health benefits and possibly improved weight control. To support weight loss efforts, the recommended dose increases to 200 to 300 minutes per week for individuals with overweight/obesity. However, when exercise interventions are prescribed without reductions in caloric intake, they often result in less weight loss than expected. Thus, the use of exercise alone as an effective strategy for weight loss can be challenged.
The MaPLE study was a randomized, controlled, crossover trial involving adults ≥60 y.o. (n = 51) living in a residential care facility during an 8-week polyphenol-rich (PR)-diet. Results from the MaPLE trial showed that the PR-diet reduced the intestinal permeability (IP) in older adults by inducing changes to gut microbiota (GM). The present work aimed at studying the changes in serum metabolome in the MaPLE trial, as a further necessary step to depict the complex crosstalk between dietary polyphenols, GM, and intestinal barrier.
Memory loss is one of the most common complaints of older adults. Lifestyle interventions, including exercise, are increasingly popular to preserve brain health in older age. While there is ample empirical evidence to support the cognitive benefits of a physically active lifestyle, the neurophysiological mechanisms are difficult to determine conclusively in humans. Over months or years, it may not be possible to disentangle the independent effects of exercise from those attributed to factors such as social interactions and diet. However, if daily exercise accumulates to produce brain benefits over time, then it stands to reason that each session of exercise may produce effects from which these long-term adaptations occur.
The importance of psychiatry and behavioral health in the delivery of overall health care and optimization of health is widely acknowledged. However, the stigma related to mental illness in society and the separation of psychiatric care from traditional medical settings has resulted in significant challenges in integrating all aspects of care necessary in maintaining optimal health and well-being
