Figure 2.

Strength evolution of both trained (right) and untrained (left) hands during the study. The continuous (hyperthermia) and the discontinuous (normothermia) lines represent the evolution of strength in basal (pre-exercise) conditions. Wilcoxon Test: Pre-post differences of each day in each group: * p < 0.05; ** p < 0.01; Pre-pre differences between consecutive days for each group: ^ p < 0.05; ^^ p < 0.01. Mann–Whitney U Test: Differences between groups at each time point: + p < 0.05; ++ p < 0.01.
