EFFECTS ON POSTURAL CONSTRAINTS ON OVERARM THROWING
Keywords: kinetic chain, velocity, transport
AbstractThis study explored the effects of postural constraints on overarm throwing. 10 participants were required to perform an overarm throwing movement by 3 tasks which under postural constraints. Tasks were including trunk-fixed, sitting, and standing. 10 pieces of 3D motion capture system were used to record the maximum velocity of body segments as data and one-way repeated measures ANOVA (a=.05) with HSD post-hoc tests was conducted to analysis the data. Therefore, the results indicated that the performance of overarm throwing by 3 tasks were different significantly, which proved the kinetic chain formed by links connected in series gave body segments more velocities. Moreover, it meat trunk and lower limbs played the roles to transport velocity as performing overarm throwing.
