1C There are different types of contractions associated with the skeletal muscles Isometric A muscular contraction in which the length of the muscle does not change isotonic A muscular contraction in which the length of the muscle changes eccentric An isotonic contraction where the muscle lengthens concentric An isotonic contraction where the muscle shortens In isotonic contractionthe tension remains same in the muscle and the muscle length changes during muscle contraction It occur only when a muscles maximal force of contraction exceeds the total load on the muscle In this the length of the muscle changes during contractionIsotonic exercise includes stair climbing pushups squats and biceps curls Other options Treppe See Answer
