Changes in Shoulder Girdle Muscle Activity and Ratio During Pilates-Based Exercises.

Among the Pilates-based exercises, the modified side-arm (MSA) and modified high-five (MHF) are commonly used for shoulder strengthening and rehabilitation. This study examined shoulder girdle muscle activity and ratios across different spring intensities. Twenty-two healthy males performed the MSA and MHF using yellow (low), blue (medium), and red (high) springs.
