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 fibres are cylindrical, and multinucleated. Muscle fibers are in turn composed of myofibrils. The myofibrils are composed of actin and myosin filaments, repeated in units called sarcomeres, the basic functional units of the muscle fiber. The sarcomere is responsible for the striated appearance of skeletal muscle, and forms the basic machinery necessary for muscle contraction. The term muscle refers to multiple bundles of muscle fibers called fascicles. All muscles also contain connective tissue arranged in layers of fasciae.
