Resistance Training and Testosterone Levels in Male Patients with Chronic Kidney Disease Undergoing Dialysis

Table 4

Muscle fibre size and muscle strength for those patients who completed the intervention (𝑛=12). The control period was between the baseline and pretraining test. The training period was between the pretraining and the posttraining test.

Variables	Baseline	Pretraining	Posttraining
Muscle fibre size
Type 1 (µm^2)	4896 (3138–8453)	4760 (2853–7891)	4730 (2273–9204)
Type 2 (µm^2)	3485 (2778–6067)	3246 (2284–5336)	3832 (2829–6953)
Knee extension strength
Right (N)	349 (195–511)	349 (200–583)	460 (258–695)***
Left (N)	299 (216–595)	341 (193–558)	400 (238–657)**

Data are presented as median (range). N: Newton. Between pretraining and posttraining **P < 0.010; ***P < 0.005.
