Abstract

This study investigated the ratios of the three phases in triple jumping by novice (n=8) and experienced (n=5) athletes during indoor competition. Video data were analysed to determine the phase distances for 58 competitive triple jump performances. Phase ratio percentages were calculated for each of the trials. There were significant differences in the step phase percentage (p<0.05) and jump phase percentage (p<0.05) for the two groups. At the group level, novice jumpers appeared to favour a jump-dominated strategy, whilst the technique was hop-dominated for experienced jumpers. Using pooled data masked individual variations in strategy and so these group results should be viewed with caution. Future research will focus on the longitudinal development of individual performers and the mechanics of the associated changes in effort distribution.
