Abstract
Previous reports have linked sprints to stretch-shortening cycle movements, such as jumps, but very few have quantified these effects in relation to resisted sprint training. PURPOSE: The aim of this study was to determine the effects of speed chute training on various jump performance abilities. METHODS: Fifty four young, well-trained cadets (matched for 40m run time) were randomly divided into two groups: speed chute (n=27) and flat training (n=27). Both groups followed a training programme which comprised three training sessions per week (eight sprint-runs over 40 m distances with a 5 minute interval) on an indoor track for a period of 7 weeks. Vertical and horizontal jumping performance (pre and post the training period) was assessed via a range of jump tests measured on a force platform and a sand pit. These included the Squat Jump (SJ), the Counter Movement Jump without (CMJ), and with arm movement (CMJA), the Standing Broad Jump (SBJ), the Five Horizontal Bounds (FHB) and the Drop Jump from a 30cm height (DJ30). All cadets throughout the study ate from the same menu and receive strictly the same opportunities for rest, sleep and activity at specific times. RESULTS: The cadets in the speed chute group (pre versus post training) significantly (ANOVA repeated measures; p<0.05) improved on SBJ (2.21 ± 0.45 m versus 2.30 ± 0.55 m), CMJ (30.2 ± 6.7 cm versus 31.0 ± 7.9 cm), CMJA (33.4 ± 5.7 cm versus 35.0 ± 7.9 cm), FHB (10.5 ± 1.0 m versus 11.3 ± 1.1 m) and DJ30 (33.8 ± 7.2 cm versus 36.0 ± 5.9 cm respectively. The cadets in the flat training group (pre versus post training) improved only in SBJ (2.15 ± 0.40 m versus 2.22 ± 0.45 m). CONCLUSIONS: This study suggests that speed chute training can significantly improve short and long stretch-shortening cycle actions and indirectly lead to an enhanced sprint performance.
