Journal of Sports Science and Physical Education 5(2): 15-23, 2016 - This study was conducted to determine the relationship between lower body muscle architectures and lunges performance. Thirty recreationally active, untrained men (mean age = 22.21 ± 1.59 yrs old) were recruited and involved in two testing sessions; i) anthropometrics and muscle architecture, and ii) multiple-repetition maximum (RM) lunge test. Muscle thickness, pennation angle and fascicle length of vastus lateralis (VL), vastus medialis (VM), rectus femoris (RF) and biceps femoris (BF) were analysed using ultrasonography. Multiple-RM lunge testing was used as an estimation of 1RM lunges performance. Correlation analysis was used to determine the relationship between lower body muscle architectures and lunges performance calculated absolutely and relatively (1RM/body mass). The overall results showed that muscle thickness and pennation angle of all muscles were significantly positive correlated with lunges performan.....

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 mu.....

Sepak Takraw (ST) is considered Malaysia’s national sport, and the nature of this sport requires players to be sufficiently acrobatic. Therefore, players were expected to jump and regain their balance, challenging their dynamic balance (DB). Nonetheless, range of motion (ROM) is closely related to balance. Hence, this study aimed to compare recreational ST players’ ankle ROM and DB differences with and without ankle injuries...
