Figure 3.

The effects of training alone (placebo group) and training with BCAA supplementation are shown for men (top, (A–C)) and women (bottom, (D–F)). T0 represents the start of the experiment (time zero) and T1 represents the end of the experiment (six months later). In this representation, the central box covers the middle 50% of the data values, between the upper and lower quartiles. The bars extend to the extremes, the central line represents the median, and the cross indicates the mean value. p values were obtained using a paired t-test comparing values from the same subjects before and after the experiment.
