Improved ability to live independently in old age. Physical activity: any body movement carried out by the skeletal muscles and requiring energy. Exercise: planned, structured, repetitive movement of the body designed to improve or maintain physical fitness. Additional benefits from higher intensity, greater frequency, and longer duration of physical activity. Most health benefits occur with at least 150 minutes per week of moderate intensity physical activity, or. 75 minutes of vigorous intensity aerobic physical activity, or a combination of the two. For health benefits and weight management, 60 to 90 minutes of moderate intensity activity every day. Physical fitness: a set of physical attributes that allows the body to respond or adapt to the demands and stress of physical effort. Adaptation to physical stress: the body adjusts to meet increasing demands placed on it. Specificity: the body systems stressed by exercise will be the ones to adapt.
