reciprocal inhibition

A

relaxation of musculature on one side of a joint to accommodate a contraction of opposing musculature on the opposite side

34

genetics, health status, fitness level, routine physical activity performed

36
Q

females display greater ROM in specific movements compared to males due to anatomical variances including
