Table 8 Differences in percent decline for peak torque (post-supplementation – pre-supplementation) during that fatigue test with identification of the individual subjects that exceeded the minimal important difference

From: The effects of phosphocreatine disodium salts plus blueberry extract supplementation on muscular strength, power, and endurance
