Abstract:
Prior research suggests peak sprint power (PSP) is correlated with cycling sprint times, indicating that individuals able to produce higher PSP demonstrate faster ride times. These faster ride times are indicative of better performance in sprint cycling competitions. PURPOSE: The primary aim of the study was to determine if a vertical jump height (VJH) test and other anthropometric and demographic measures could model sprint cycling power. It was hypothesized that a higher VJH would correlate with a higher PSP. METHODS: Trained cyclists were enrolled in the study and completed a series of VJH tests, PSP tests, and provided demographic and anthropometric data. Multiple regression examined the predictors of normalized peak sprint power (NPSP). PSP was normalized by taking the PSP and dividing by the subject's mass. RESULTS: The average normalized PSP the subjects produced (15.5 ± 3.1 watt/kg) and average VJH (37.4 ± 7.5 cm). There was a significant positive association between VJH, average VJH velocity, and NPSP (r2 = 49.24%). CONCLUSION: The results indicate that a higher VJH will indicate that a cyclist will have a higher normalized PSP.
