The purpose of this study was to determine the influence of shooting with different force on motion variability of top snooker players. Six professional male players shot with hard force shot (HF) and soft force shot (SF), then coefficient of multiple correlations (CMC) and coefficient of variation (CV) were calculated. In SF, flexion-extension (p=.045) and adduction-abduction (p=.001) of shoulder showed higher CMCs than HF and adduction-abduction (p=.042) of shoulder showed lower CV than HF. In SF, flexion-extension of wrist showed higher CMC (p=.035) and lower CV (p=.030) than HF and adduction-abduction of wrist showed higher CMC (p=.039) and lower CV (p=.036) than HF. There was no difference in CMC and CV of cue. Thus hard force shot might increase motion variability of upper limbs.
