Table 5 Effect sizes for force production

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

   Maximal Concentric Force Maximal Eccentric Force
M F M F
Max Test NC 0.27 0.00 0.24 −0.26
C 0.42 0.42 0.08 0.09
Exercise Sets NC 0.43 −0.14 −0.08 −0.15
C 0.29 −0.06 −0.04 0.02
  1. Cohen’s d effect sizes calculated as the difference between means of NC or C supplement and placebo, divided by the pooled standard deviation. The effect size for the exercise sets encompasses all five exercise sets
