Abstract

Recovery has routinely been determined by using a counter movement vertical jump (CMJ). While a CMJ has been proven effective to determine recovery, there may be alternatives that are more efficient and less physically taxing such as the Perceived Recovery Status Scale (PRS). The PRS is a non-invasive, and accurate psychophysiological tool designed to measure recovery and its correlation to performance. PURPOSE: To determine the relationship between vertical jump and perceptual recovery status as a method for monitoring recovery during repeated sprint efforts. METHODS: Eight college-aged individuals (age=23±0.9 yr; Ht=65.3±4.2 in; Wt=67.1±9.3.4 kg; BF%=17.5±8.4) performed repeated sprints. The protocol consisted of three sets of eight 30m sprints on the Woodway Curve treadmill with 45-sec of rest between each sprint. The sets were separated by 5 min of passive rest. During each sprint, power output (PO) was measured; RPE was recorded immediately following each sprint. Immediately before the next set of sprints a CMJ was performed on a force plate where vertical jump (VJ) height was recorded. RESULTS: A 1-way repeated ANOVA found a significant main effect of sprint set on RPE (p=.044) and PRS (p=.000). Subsequent pairwise comparisons revealed significant differences among RPE between sprint sets 1 and 2 (p=0.05), and in PRS between sprint sets 1 and 2 (p=0.001), and sprint sets 1 and 3 (p=.002). Correlation coefficients showed the strongest relationship between PRS and delta MP to be moderate, and significant at p≤0.05 (R2=0.34) and the correlation coefficient was 0.57. All other correlations were determined as weak and not significant. CONCLUSION: Results from the current study suggest that PRS may demonstrate a stronger relationship with change in repeated sprint performance within a session than using VJ. However, neither index of recovery was robust, and may indicate that these measures may be more appropriate for use between day-to-day training sessions (as previously established) and not, necessarily, to gauge recovery.
