Abstract The aim of this study was to determine and compare the force output during lunge exercises with different loadings; i) high load forward lunge (70% 1RM) and ii) low load forward lunge (30% 1RM). Thirty recreationally active, untrained men were recruited and were assigned to perform forward lunge with 70% 1RM (70FL) and 30% 1RM (30FL) with both their dominant and non-dominant leg. For both dominant and non-dominant leg, all the force variables during 70FL were significantly greater compared to 30FL. Results also showed that time to peak force and stance time was significantly shorter during 30FL compared to 70FL. Besides that, all the force variables were greater in the dominant limb compared to the non-dominant limb. Time to peak force and stance time were also shorter in dominant limb compared to the non-dominant limb. As the conclusion, assymetries exist among untrained men during forward lunge exercise for both low loads and high loads.
