Abstract


This study was conducted to determine and compare the kinematics during low load (30% 1RM) and high load forward lunge (70% 1RM). Thirty recreationally active, untrained men (mean age = 21 ± 0.83 years old) were recruited and were assigned to perform forward lunge with 30% 1RM (30FL) and 70% 1RM (70FL) with both their dominant and non-dominant leg. No significant differences were found on all the joint angles (ankle, knee, hip and trunk) between 30FL and 70FL. Ascend time, descent time and time taken were found to be significantly shorter during 30FL while step length was found to be significantly greater during 30FL. Besides that, ascend time, descent time and time taken were significantly faster and the step distance was significantly greater in the dominant limb compared to the non-dominant limb during both 30FL and 70FL. To conclude, kinematics during movement are affected by the loadings lifted and the dominant and non-dominant sites of limb used.
