Table 1.

Exercise performance recovery effect sizes: REx + CHO vs. REx + PRO.

Cohen Effect Size Probability of Protein Superiority
Outcome 10 h recovery 24 h recovery 10 h recovery 24 h recovery
Protein metabolism
Net protein balance 0.61 0.69 67% 69%
Knee extension
Peak isometric force 0.28 0.76 58% 70%
Repetitions to failure 0.11 0.44 53% 62%
Wingate test
Peak power 0.27 0.55 58% 65%
Mean power 0.49 0.12 64% 53%

Unless indicated otherwise, effect sizes were calculated as the mean difference between PRO and CHO divided by the standard deviation (SD) of Rest (control) [40]. The thresholds for Small, Moderate and Large effect sizes are 0.2, 0.5 and 0.8, respectively. [39]. Probability of protein superiority: the percent chance that a value from PRO will be greater than CHO, calculated as % = φ (d/2), where φ is the cumulative distribution function of the standard normal distribution, and d is the Cohen Effect Size [42]; 50% = no effect. REx = whole body resistance exercise.
