Considering the Length-Tension Relationship of skeletal muscle fibers, over stretching a muscle fiber or not stretching a muscle fiber enough, results ina decrease in force developed (during contraction) because: A. An "over-stretched" muscle fiber or an “under-stretched" muscle fiber will not allow Calcium, from the sarcoplasmic reticulum, to adequately diffuse into the cytoplasm. B. An "over-stretched" muscle fiber or an “under-stretched" muscle fiber will not allow an optimum amount of contact and overlap for the contractile proteins. C. An "over-stretched" muscle fiber or an "under-stretched" muscle fiber will not allow the Action Potential to reach the troponin-activation channels. D. An "over-stretched" muscle fiber or an "under-stretched" muscle fiber will not allow the Sodium current to depolarize the membrane.

The human body has mainly two types of muscle fibres: slow-twitch and fast-twitch. The { slow or fast} twitch contract slowly and resist fatigue and produce most of their energy through { aerobic or anaerobis} rispiration. These muscle fibres are best used for activities like { weight lifting and playing tennis or biking and jogging} The { slow or fast} twitch are adapted for the rapid regeneration of power. They can best be used in activities such as { weight lifting and playing tennis or biking and jogging}. They are rich in glycogen and depend on { aerobic or anaerobis} rispiration. to produce energy. This leaves them vulnerable to the accumulation of lactate and they fatigue quickly. which one are those? the answers
