The WHO Guidelines on Physical Activity and Sedentary Behaviour provide comprehensive recommendations for promoting physical activity across various age groups and populations, including children, adults, older adults, pregnant women, and individuals with chronic conditions or disabilities. These guidelines emphasize the importance of regular physical activity for preventing and managing major health issues such as heart disease, diabetes, and cancer, as well as improving mental health and overall well-being. The guidelines advocate for a minimum of 150-300 minutes of moderate aerobic activity per week for adults and daily activity for children and adolescents. They also highlight the risks associated with excessive sedentary behavior and offer strategies for incorporating muscle-strengthening exercises to enhance balance and prevent falls in older adults. The guidelines aim to support national health policies and contribute to achieving global health objectives, particularly the Sustainable Development Goals.
