MUSCLE PHYSIOLOGY

Detailed explanation-1: -During isometric exercises, the muscle doesn’t noticeably change length. The affected joint also doesn’t move. Isometric exercises help maintain strength. They can also build strength, but not effectively.

Detailed explanation-2: -Both types of exercise can strengthen your muscles, and you’ll improve stability and balance with isometric exercises in a low-impact, joint-friendly manner, while you will increase muscle strength, size, mobility, flexibility, and metabolic rate with isotonic exercises.

Detailed explanation-3: -Isometric contractions are contractions in which there is no change in the length of the muscle. No joint or limb motion occurs. Isotonic contractions occur when the muscle changes length, producing limb motion.

Detailed explanation-4: -Isometric exercise is unique in its ability to rapidly increase muscle strength and tone muscle faster than that seen for dynamic exercise.-Petrofsky, et al. Numerous studies have found that isometric training strengthens muscles faster than dynamic, moving methods.

Detailed explanation-5: -Nervous system fatigue. Cardiovascular system can be affected as well. Increase blood pressure. Affects coordination, and. Decreases soft tissue elasticity.
