Table 4 Force production during exercise session

From: Effects of two pre-workout supplements on concentric and eccentric force production during lower body resistance exercise in males and females: a counterbalanced, double-blind, placebo-controlled trial

  1. aconcentric force production during set 4 was lower than set 1 (p = 0.02)
  2. *significantly different than other conditions, as indicated by significant pairwise comparisons (p < 0.05)
