Document Summary
Kin100 lecture 7 musculoskeletal changes across the life span. Bone mineral density: race, gender (30% less in women) Muscle volume: body size, sex hormone, males have 40% more than adult females (females have a lot less upper body muscle volume, lower limb muscle mass, upper limb muscle mass (based on activity) Sexual dimorphism: overlap is so large it"s hard to predict, the difference is coming to the center, height 1. 08:1, weight 1. 25:1, lbm 1. 45:1, nutritional requirements and athletic performance. Shoulder size: width of shoulders in cm = ________cm, multiply by 3 x 3, subtract width of pelvis -________cm, androgyny index 90% accurate. Definitions: auxology growth, onset of changes, magnitude, duration, gerontology aging, anatomy, effects of aging, effects of inactivity. Growth, maturation, aging: puberty delayed period of rapid growth, aging, begins as soon as a peak in any parameter is reached, 40-60 years of aging, fight the decline, lean muscle mass is what we want to retain.
