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