Document Summary

Increased muscle size/function: lower bo, lower visceral & total adiposity. How does pa improve life: counteracts age-related changes in physiology, address risk factors for chronic disease. Percentage of australian adults meeting the pa recommendations (150. Time spent in various activity types by australian adults. Goals: adults 18-64yo, improve appearance, weight control, feel good, cardiometabolic disease prevention, fun/socialise. Intensity: on a scale of 0 to 10: 5 to 6 for mpa and 7 to 8 for vpa: type: anything that does not impose excessive musculoskeletal strain, time: mpa: 150 300 min/week, or (vpa) Rt in nonagenarians (~90yo): relative strength of muscle correlated to walk time, decrease in strength = increase in walk time, functional decline from strength. Increase in functional capacity (gait speed) by ~50% Prescription: coordinated & systematic effort to increase pa, target individuals, whole populations or population sub-groups (cid:498)designer(cid:499) concept to compensate for, eliminating need for pa in modern world, inability to spontaneously adapt to unhealthy environment.
