Purpose: The purpose of this study is to investigate the effect on static and dynamic balance after an exerciseintervention, combining single-leg jump training with various directions squat training.
Methods: Training groups was randomly divided into two groups. the experimental group performed thecombining exercise while the control group performed only sigle-leg jump training. Both groups perforemdexercise a total of 3 sets, 20 times per set with each leg 3 times a week during 4 weeks. As for a singlejumping training exercise program of this study, jumping in place (step 1) during week 1, jumping left andright (step 2) during week 2, and diagonal jumping (step 3) during weeks 3 and 4 were performed. Especiallyas for the experimental group, single-leg jumping training and single-leg squat training were performed inparallel.
Results: The results were as follows. First, in the experimental group, there was an improvement in Modifiedclinical test sensory interaction balance (mCTSIB) test and Unilateral stance (US) test (p<.05). Second, theexperimental group had better balance in the Rhythmic Weight Shift (RWS) test and the Limits of stability (LOS)test than the control group (p<.05).
Conclusion: In clinical practice, combining single-leg jumping with single-leg squats in various directions canbe expected to improve not only left/right balance ability but also forward/backward balance for patients withimpaired balance ability. Also, it will be helpful when training is performed, changing the performance speed.
