【Haichuan Teahouse】What do you think of Weekend Warriors?

Thread Content

Weekend warriors are people who are busy during the week and only use their weekends to engage in intensive physical exercise. For example: some runners are busy from Monday to Friday, and run a half-marathon or even a full marathon 1 to 2 times on Saturdays and Sundays. They are busy with work on weekdays and have no time for exercise; they hope to engage in intensive workouts on weekends to make up for the lack of exercise during the day. Such runners are really conscientious! But is such a scheduling of exercises really good, and is it scientific? We all know that regular aerobic exercise is beneficial to physical health. Lack of exercise leads to an increase in diseases and mortality, while regular physical activity can reduce the risk of death and lower the incidence of various diseases such as cardiovascular disorders. The American Heart Association and the American College of Sports Medicine have identified two key recommendations in their guidelines for physical activity: First, adults should engage in moderate-intensity exercise at least 5 days per week, for at least 30 minutes each time, so that the total weekly duration of moderate-intensity activity exceeds 150 minutes ； II. Adults can also engage in high-intensity exercise for at least 3 days per week, with each session lasting at least 20 minutes, so that the total weekly time spent on high-intensity activities exceeds 75 minutes ； The guidelines recommend that exercise be spread out over several days of the week, but they do not explicitly state that it is inappropriate to engage in 150 minutes of moderate-intensity activity or 75 minutes of high-intensity activity at one time. Is the way weekend warriors exercise reasonable then?
