| This research consisted of four studies that were conducted as acute and chronic studies. Study 1 and Study 3 were conducted to analyse the biomechanical responses of different lunge protocols. Study 2 and Study 4 were conducted to determine and compare the chronic effects of different lunge training programs on physical performances [lunge one repetition maximum (1RM), vertical jump, standing broad jump and change of direction] and muscle architecture. Study 2 and Study 4 also attempted to determine whether there is any relationship between muscle architecture and physical performance. Kinematics, kinetics, muscle activity and fascicle behaviour of both dominant and non-dominant limb were determined and compared between; i) step forward lunge (SFL) and jump forward lunge (JFL) among fifteen university badminton players (Study 1) and ii) 30% 1RM (30FL) and 70% 1RM (70FL) among thirty untrained men (Study 3). Eight weeks effects of different lunge training on physical performance and muscle architecture were determined and compared among thirty recreational badminton players (Study 2) and 30 untrained men (Study 4). Results in the acute studies showed muscle activity, force output and fascicle behaviour were greater during JFL compared to SFL and during 70FL compared to 30FL. Results in chronic studies showed the improvement of lunge 1RM, vertical jump and standing broad jump were greater among JFL compared to SFL training (Study 2) and 70FL compared to 30FL (Study 4). Results also showed that eight weeks of lunge training were enough to induce changes in muscle architecture. Overall, this research provides the findings that showed the different in biomechanical responses of different lunge protocols and the existing relationship between muscle architecture and lunge performance. Besides that, this research also demonstrated how the different in responses later brought to different adaptations in physical performances and muscle architecture adaptation. |
