From: Regular soccer training improves pulmonary diffusion capacity in 6 to 10 year old boys
Mean (± SD) Pulmonary parameters [membrane factor for CO (DMCO), nitric oxide lung transfer (TLNO) and carbon monoxide lung transfer (TLCO), lung capillary blood volume (Vc) and alveolar volume (VA)], measured just afte maximal exercise before (T1) and after the training period (T2) in soccer (SG) and control groups (CG). NS: no significant difference. *: Significant difference: *p˂0.05 and **p˂0.01
