Jumping Abilities and Swimming Grab-Start Performances in Elite and Recreational Swimmers

Abstract

Jumping Ability and Swimming Grab-Start Performance in Elite and Recreational Swimmers This study examined the relationships between the performances of a swimming grab start and each of countermovement jump for distance, countermovement jump for height, squat jump for distance, and squat jump for height. Nine elite and 7 recreational female swimmers performed 6 trials in each of the 4 jumping techniques and six 25-m freestyle sprints after a grab start. Elite participants performed significantly better in the start performances, and this was attributed to the greater horizontal impulse. Correlations in the elite group revealed that grab-start performance was not related to performance of any jumps. This suggests that the grab start is independent of the jumping techniques for this group, and performance of one skill might not translate to performance in the other. Significant correlations were found between performance of the grab start and the 4 jumps in the recreational group, possibly because of adoption of an "incorrect" motor pattern that might be similar to those of the jumps. This study highlighted the importance of practicing the start as a whole skill during training.
