Document Summary

Unit 3 starts - pa benefits: musculoskeletal health. Contributes to bone fracture risk -> hip, vertebrae, wrist. Joint pain & dysfunction, costly (productivity & med costs) Females mature sooner - males have more time to develop bones. Scan produces high quality images to measure fat and lean body tissue. Absorptiometry: full body x-ray to determine total body adipose tissue, as well as bmd. Scale inside a water tank measure underwater weight and then weight displacement. Equilibrium fat stores = (energy intake) - (energy expenditure) + (physiological adjustment) At least a 5% loss of body weight. Method to determine the dose or recommended amount of physical activity to achieve an outcome. Multiple the time in hours by the met value. Total volume of energy expenditure important, details unclear. Would require a significant amount of energy expenditure. Daily pa - 45 minutes @ 5 mets, 70 minutes @ 3 mets, 22 minutes @ 10 mets.
