Measures of Wingate anaerobic capacity performance and fatigue index
| Baseline | Placebo | PWS | Effect size | Difference | ||
|---|---|---|---|---|---|---|
| PWS-Baseline | PWS-Placebo | |||||
| Peak Power (W) | 723 ± 205 | 722 ± 208 | 782 ± 191* | 0.28 | 0.3 | Small |
| Mean Power (W) | 538 ± 148 | 535 ± 149 | 569 ± 133* | 0.22 | 0.24 | Small |
| Minimum Power (W) | 331 ± 90 | 336 ± 87 | 356 ± 83 | 0.29 | 0.24 | Small |
| Fatigue Index (%) | 52.8 ± 6.6 | 53.3 ± 8.4 | 53.6 ± 8.7 | 0.10 | 0.03 | Trivial |
Note: Data are presented as mean ± standard deviation. PWS pre-workout supplement. * = significantly greater than baseline and placebo (p < 0.05). Effect sizes, < 0.2 = trivial; 0.2 to 0.49 = small; 0.5 to 0.79 = moderate; > 0.8 = large
