purpose of this study was to investigate the effect of squat exercise on the muscle activity and myocardial burden of the lower limb according to water depth.
Subjects performed aquatic squat at knee and waist levels. The SBP and leg EMG were measured before and after the experiment, and the myocardial burden was calculated by multiplying the measured heart rate and SBP. Statistical analysis was done by Two-way ANOVA, The value of significance was.05.
Both the aquatic squats showed a significant increase in lower extremity muscle activity and myocardial burden after the operation. Among the two methods, the knee-level squat increased the muscle activity and enhanced myocardial burden rate.
