INTRODUCTION: Lunge exercises are utilized to strengthen the knee before and after knee surgeries, but lack of research on kinetics of lateral lunge has been detected. This study was to investigate whether knee joint moments would be affected by lateral lunge.
METHODS: This is a cross-section prospective study. Ten healthy participants performed lateral lunge and normal walking. A motion capture system and force platform were used to collect lower limb movement. Biomechanical parameters, e.g. joint moments and forces, were calculated using a biomechanical model, and the outcomes were statistically compared between lunge and walking.
RESULTS: The results showed that knee moments in lateral lunge were significantly higher by roughly 34% in abduction than in walking; knee force had significantly higher in the lateral direction by roughly 50%; hip moments were significantly higher in external rotation direction by roughly 53% in lunge than in walking. In general, joint angles in the knee and hip were significantly larger in lunge than in walking. However, other parameters in lunge were less than in walking.
CONCLUSIONS: These findings provide useful reference to clinicians when prescribing lateral lunge to patients in rehabilitation and to coaches when arranging lateral lunge as an exercise for sportsmen.
