Document Summary

Any exercise that uses external resistance to progressively overload skeletal muscle. Muscular endurance: how many times can submaximal effort be repeated. Increase in cross sectional area of muscle fiber. Weight training gained popularity, but was oly associated with: Today, we recognize that resistance training is needed for health. Musle adaptations comes from the fatigue signal. Adults should do muscle strengthening exercises that are moderate/high intensity and involve all major muscle groups on 2 or more days per week, as these activities provide additional helath benefits. Muscle is very malleable and changes in response to stimuli. Specificity: muscle will adapt if worked, specific to the stimulus you provide. Overload: muscle has to be overloaded; will not adapt if same stimulus constantly provided. Progression: must consistently overload; not just one time. Nerve impulses from cns activate appropriate motor units/muscle fiber. Fibers use creatine phosphate and glcogen for anaeobic energy production. Same amount of cells, cells just get bigger.
