Document Summary
Aerobic (endurance) type activities decrease the number of ca pumps. Decreasing the number of attached cross-bridges (b/c increase force = increased number of attached cross-bridges and the relationship is inverse) and increasing the rate of. Change from type i to type ii by doing activities which keep your epinephrine (adrenalin) levels high. It depends on the nature of the task the muscle cell must do. The fastest myosin in human skeletal muscle is called type iix. (myosin = iix; fiber = iib) Type i and type ii myosin differ in their contractile velocities because they have different rates of adp release. Lattice spacing describes the spatial arrangement between thick and thin filaments (and is related to velocity of contraction, not force). Makes it harder for the myosin to detach from actin. The contractile velocity of fast myosin is roughly ____ times faster than slow myosin. (3 times)
