Abstract

To evaluate the effect of intensive training on ventilatory functions in soccer players, comparisons of various ventilatory parameters were made before and after 5-5.5 months of intensive training. The subjects were 15 members of a university soccer team with mean age and career of 19.9 and 8.3 years, respectively. Ventilatory parameters studied were those obtained by the analyses of forced expiratory volume and maximal expiratory flow-volume curves, as well as spirometric measurements of VC and MVV. After intensive training, volume parameters, such as VC, FVC and FEVl & 3 as well as flow parameters, effort-dependent and effort-independent, such as MVV , FEF200-1200, FEF25-75%, PEF, FEF25% , FEF50% , FEF75% showed significant increase. However, when the observed values of flow parameters were volume-adjusted to FVC, the differences before and after intensive training became insignificant. This suggests that enhanced ventilatory functions in soccer players after intensive training are primarily due to increase in FVC caused by increase in respiratory musle strength.
