Effects of Water Immersion on Squat and Split-Squat Kinematics in Older Aged Adults.

This study examined the effect of water immersion on trunk and lower limb kinematics during squat exercises in older aged participants. Twenty-four active older aged adults (71.4 ± 5.4 yrs.) performed squats and split-squats on land and while partially submerged in water. Inertial sensors (100 Hz) were used to record trunk and lower-body kinematics. Water immersion increased the squat depth (squat: P=0.028, d=0.63, split-squat: P=0.005, d=0.83) and reduced the trunk flexion range (squat: P=0.006, d=0.76, split-squat: P<0.001, d=1.35) during both exercises. Additionally, water immersion increased the hip range of motion during the split-squat (P<=0.002, d=0.94). Waveform analyses also indicated differences in the timing of the movements. These results showed that aquatic-based exercise generate a different exercise outcome and appear to provide an alternative option for older aged adults, allowing these tasks to be performed in a manner that is not possible on land.
