Document Summary

Overthrowing: there are a wide range of variations on the movements, timing and nature of the motion of each segment this is what makes a fastball different from a tennis serve, even though both are overarm throwing movements. Analyzing the cricket bowl: the bowler can run up to the delivery point the elbow must be straight on delivery this is faster than a baseball fastball.

With throwlike kick, distal segment (lower leg) lags behind the proximal segment (thigh) Though the skills might be very similar (i. e. tennis smash vs. badminton smash), there can be differences in technique.
