SELF-REPORTED MEASURES OF STRENGTH AND SPORT-SPECIFIC SKILLS DISTINGUISH RANKING IN AN INTERNATIONAL ONLINE FITNESS COMPETITION

摘要

To determine if self-reported performance measures could distinguish ranking during the 2016 CrossFit Open, data from 3,000 male (n=1,500; 27.2 +/- 8.4 years; 85.2 +/- 7.9 kg; 177.0 +/- 6.5 cm) and women (n=1500, 28.7 +/- 4.9 years; 63.7 +/- 5.8 kg; 163.7 +/- 6.6 cm) competitors was used for this study. Competitors were split by gender and grouped into quintiles (Q1-Q5) based upon their final ranking. Quintiles were compared for one-repetition maximum (1RM) squat, deadlift, clean and jerk (CJ), snatch, 400 m sprint, 5,000 m run, and benchmark workouts (Fran, Helen, Grace, Filthy-50, and Fight-Gone-Bad). Separate one-way analyses of variance revealed that all competitors in Q1 reported greater (p = 0.05) 1RM loads for squat (men: 201.6 +/- 19.1 kg; women: 126.1 +/- 13.0 kg), deadlift (men: 232.4 +/- 20.5 kg; women: 148.3 +/- 14.5 kg), CJ (men: 148.9 +/- 12.1 kg; women: 95.7 +/- 8.4 kg), and snatch (men: 119.4 +/- 10.9 kg; women 76.5 +/- 7.6 kg) compared with other quintiles. In addition, men in Q1 (59.3 +/- 5.9 seconds) reported faster (p = 0.05) 400 m times than Q3 only (62.6 +/- 7.3 seconds), but were not different from any group in the 5,000 m run. Women in Q2 (67.5 6 8.8 seconds) reported faster (p = 0.05) 400 m times than Q3-Q5 (73.5-74.8 seconds), and faster (21.3 +/- 1.8 minutes, p0.02) 5,000 m times than Q4 (22.6 +/- 2.2 minutes) and Q5 (22.6 +/- 1.9 minutes). Faster (p = 0.05) Fran times were reported by Q1 (men: 138.2 +/- 13.3 seconds; women: 159.4 +/- 28.3 seconds) compared with other groups, while the results of other workouts were variable. These data indicate that the most successful athletes excel in all areas of fitness/skill, while lower-ranking athletes should focus on developing strength and power after achieving sufficient proficiency in sport-specific skills.
