Abstract
The purpose of this study was to analyse the contractile properties of lower extremity muscles in collegiate bowling players using tensiomyography(TMG). Fourteen male bowling players was divided into 2 groups: ELT(excellent muscular function group, n=7), NELT(non-excellent muscular function group, n=7). TMG was recorded from the biceps femoris(BF), semitendinosus(ST), vastus medialis(VM), vastus lateralis(VL), rectus femoris(RF). The TMG parameters obtained for each muscle were maximal displacement(Dm), contraction time(Tc), contraction velocity(Vc), delay time(Td), half-relaxation time(Tr), sustained time(Ts). The result of this study were as follows: Dm in ELT group was significantly lower than NELT group on BF and ST muscle(p<.05). TC and Vc in ELT group was significantly lower than NELT group on BF muscle(p<.05). In this results may provide important information for lower extremity training and injury prevention program designing for collegiate bowling players.
