Document Summary
Innervation: sa and av nodes, myocardium: cardioinhibitory center, parasympathetic nerve fibers: vagus nerves. Muscular strength is the maximum force that a muscle/muscle group can generate and it"s calculated by 1rm. An increase in mass leads to an increase in strength, while a decrease in mass leads to a decrease in strength. After the age of 50, the body experiences sarcopenia (loss of muscle mass) accompanied by osteopenia (cid:523)loss in bmd(cid:524). There"s a loss/degeneration of motor units, as well as reorganization of motor units, which affects how many fibers we can recruit and therefore how much force we can produce. Describe the early and late phases of strength gains. Early phase- around weeks 4-6; see neural factors predominate for an increase in strength and power. Late phase- primary driver for increase in strength; occurs after 4-8 weeks of training; increase in muscle size via muscle protein accretion. Review the different types of motor units and their characteristics.
