Abstract

PURPOSE: To determine if gender affected measures of skill-based performance following 16-weeks of HIFT. METHODS: 26 apparently healthy men (n = 9; 34.2 ± 9.12 yrs; 1.78 ± 0.05 m; 91.5 ± 17.7 kg) and women (n = 17; 36.3 ± 7.84 yrs; 1.63 ± 0.07 m; 68.5 ± 12.8 kg) volunteered to complete 16-weeks (2-5 sessions/week) of HIFT, with a focus on general physical preparedness (GPP) at a CrossFit™ affiliate. Prior to training (within 2-weeks), pre-testing (PRE) measures of skill-based performance were collected. These included: Thrusters (Squat Press) - 20 repetitions for time (seconds), Double-Unders (Rope Jumping) - as many repetitions as possible in two-minutes, maximal number of Russian Kettle-Bell Swings in three-minutes, and maximal number of Burpees in three-minutes. Post-testing (POST) occurred within 2-weeks of training completion. RESULTS: Repeated measures ANOVA did not indicate any significant (p > 0.05) interaction (gender x time) for any of the skill-based performance measures. Paired-samples t-tests showed significant improvements in Thrusters (PRE: 93.50 ± 33.42 s, POST: 62.04 ± 24.32 s, p < 0.001), Double-Unders (PRE: 60.65 ± 69.42 reps, POST: 73.62 ± 69.54 reps, p < 0.001), Kettle-Bell Swings (PRE: 82.00 ± 14.26 reps, POST: 93.38 ± 12.89 reps, p = 0.001) and Burpees (PRE: 32.04 ± 8.33 reps, POST: 36.50 ± 12.46 reps, p = 0.006) for the entire group. CONCLUSIONS: This study shows that a 16-week GPP program of HIFT improves skill-specific performance in both men and women.
