Impact of exercise training on quadriceps femoris muscle CSA.

| Total CSA | All | 28 | 114.2 | 5.1 | 28 | 116.4 | 5.1 | 2.1 | 1.0 | 0.038 |

This table shows that, although patients’ total CSA (in centimeters squared) of their quadriceps femoris muscle has increased during the exercise training intervention, the impact was found statistically significant different when subgroups were compared with a one-way analysis of variance (P = 0.049).
*P < 0.05 for intragroup comparison.
