Abstract
As the implementation of frequent high intensity functional training (HIFT) participation continues to grow among a variety of individuals, recovery between bouts of training is important to consider to prevent overtraining. PURPOSE: The purpose of this study was to determine effective measures of recovery following an acute HIFT training session. METHODS: Participants (22.0 ± 2.8 years old, 173.6 ± 30.5 lbs., and 26.2 ± 8.24% body fat) consisted of 5 females and 3 males (n = 8), who were recreationally trained (30+ minutes moderate-vigorous exercise 4+ times/week) and had previous experience with HIFT training. Participants conducted a 20-minute, as many rounds as possible (AMRAP) exercise session. Data was collected prior to the exercise session and recovery was monitored for 30-minutes immediately post- and at 24-hours post-exercise. Before exercise and 24-hours post-exercise heart rate (HR), heart rate variability (HRV), vertical jump (VJ), upper body power (UBP), perceptual measures (PM) of recovery/exertion, and Altman Self-Rating Mania Scale (ASMR) were recorded. During exercise, heart rate, rating of perceived exertion, and the number of rounds completed were recorded. Data were evaluated using a Paired Samples T-test and Wilcoxon Signed-Ranks Test with significance set at p £ 0.05 for all analysis. RESULTS: Paired samples T-tests did not indicate significant differences between pre- and post-exercise in HR, HRV, and UBP but did denote significant differences between pre- and post-exercise in VJ (21.4 ± 7.7 vs 19.9 ± 7.1 inches). Wilcoxon-Signed Ranks Tests did not demonstrate significant differences in PM or ASMR. CONCLUSION: Possible limitations of this research include the small sample size. Based on our data VJ and UBP were the only measures that demonstrated pre- to post-exercise differences and as a result these measurements appear to be parameters that are sensitive to detecting fatigue induced from an acute bout of HIFT.
