This study was conducted to determine and compare the muscle activity during step forward lunge (SFL) and jump forward lunge (JFL) in badminton. Fifteen university badminton players (mean age = 22.07 ± 1.39 years old) were recruited and were assigned to perform SFL and JFL while holding a badminton racquet using their preferred hand. Muscle activation of vastus lateralis (VL), vastus medialis (VM), rectus femoris (RF), biceps femoris (BF), gluteus maximus (GM), medial gastrocnemius (MG), and lateral gastrocnemius (LG) were analysed and compared between SFL and JFL and also between dominant and non-dominant lower limb in each lunge protocol. Results showed for both the dominant and non-dominant lower limb, all the muscle activation was greater during JFL compared to SFL except for the MG muscle. All the muscle activation was also found to be greater in the dominant compared to non-dominant lower limb for both lunge protocols. Overall, findings demonstrated the existence of differences in muscle activation across difference protocols of movement and different site of limbs. This should be taken into consideration for developing training program in order to enhance performance and reduce the risk of injuries.
