The relationships between selected sprint specific bounding exercises and sprint
performance were analysed using fourteen sprint athletes (7 elite performers, 7 sub-elite
performers). Subjects were required to perform sprints over 60m, Counter Movement
Jumps with and without loading (20kg), High Speed Alternate Leg Bounding over 30m
and High Speed Single Leg Hopping over 20m. All athletes were subject to
anthropometric measurement (Height, Weight and Leg Length). Of all variables
measured, the Elite group were significantly better (p<0.001) in Counter Movement
Jump, Time to 60m, Time from 30m to 60m and in their Maximal Running Velocity.
Linear regressions were carried out on all variables that correlated with Time to 30m
(Acceleration Phase) and Maximal Running Velocity at both the pO.OOl and p<0.01
level of significance. This allowed several prediction tables to be compiled that had
performance measures (sprints and jumps) that could be used as testing measures for
sprint athletes to determine their Acceleration Phase and Maximal Running Velocity. A
stepwise multiple regression demonstrated that Time to 60m was the best predictor of
Maximal Running Velocity. Time to 60m, Leg length, High Speed Alternate Leg
Bounding and Sprint Stride Rate were the best predictors of the Acceleration Phase. A
Stepwise cross-validation linear discriminant function analysis was used to determine the
best predictors from both sprint and jump measures that would distinguish an athlete as
an elite or sub-elite performer. From sprint variables, Time to 60m and Time to 30m were
the two variables that best placed a sprint subject in either the Elite or Sub-elite group.
From the bounding variables, Counter Movement Jump and the Ground Contact Time of
the High Speed Alternate Leg Bounding were the two variables that best placed a sprint
subject in either the Elite or Sub-elite group. The present study suggests that Time to 60m
is the best predictor of Maximal Running Velocity and Acceleration Phase. Counter
Movement Jumping and High speed Alternate Leg Bounding are also useful tools in
developing and testing elite sprint athlete performance.
