The Weight Watchers weight loss plan is designed for a safe rate of weight loss - up to two pounds per week (after the first three weeks). If you lose at a greater rate, you must review the Plan guidelines and adapt them, if necessary, to avoid rapid weight loss.
The oxygen-binding. function of myoglobin, in situ in the bundles of muscle. fibers, was abolished by chemical treatment, and the contribu-. tion of myoglobin toward the oxygen uptake of the muscle fiber. bundles was estimated from the difference in the steady state.
Muscle fatigue, which has many contributing factors, occurs when muscle can no longer contract. An oxygen debt is created as a result of muscle use. The three types of muscle fiber are slow oxidative (SO), fast oxidative (FO) and fast glycolytic (FG). SO fibers use aerobic metabolism to produce low power contractions over long periods and are slow to fatigue. FO fibers use aerobic metabolism to produce ATP but produce higher tension contractions than SO fibers.
