This table provides an overview on how the changes of total CSA (quadriceps femoris muscle) during the training intervention are correlated with the impact on functional capacity, aerobic capacity, muscle strength, and exercise tolerance. Pearson’s correlation coefficient is provided for all variables.

*P < 0.05.
