Document Summary
Designing resistance training programs (pages 181-218) part 1. A systematic program of exercise for the development of the muscular system. Builds bone mass: increase in bone density & bone strength, counteracts loss of bone mineral, decreases the risk of falls with age. Increase in size and strength of ligaments and tendons. Decreases fat mass & relative body fat. May prevent the development of low back syndrome. Identify physical activities in which slow-twitch muscle fibers or fast-twitch muscles fibers predominate. Hypertrophy: an increase in the size of a cell or tissue larger muscle fibers. Hyperplasia: increase in number of muscle fibers. Muscle learning: body"s ability to recruit motor units increases strength even before muscle size increases. First 2-8 weeks: rapid increase in strength due to neural adaptations. No difference in rate of progression between males and females. 8-10 weeks: muscle hypertrophy contributes more than neural adaptation to strength gains, but hypertrophy eventually levels off.
