Ventilatory response to exercise of elite soccer players

Background: The purpose of this study was to evaluate the role of ventilatory parameters in maximal exercise performance in elite soccer players. Methods: From September 2009 to December 2012, 90 elite soccer players underwent evaluation of lung function test and ergospirometry by means of an incremental symptom-limited treadmill test. Results were analyzed according to i) maximal exercise velocity performed (Hi-M: high-performers, > 18.65 km/h; Lo-M: low-performers, < 18.65 km/h) and ii) usual role in the team. Results: Hi-M showed higher peak minute ventilation (V E-peak: 158.3 +/- 19.5 vs 148.0 +/- 18.54 L/min, p = 0.0203), and forced expiratory volume at first second (5.28 +/- 0.50 vs 4.89 +/- 0.52 liters, p < 0.001) than Lo-M, independently of playing role. Moreover, a significant correlation between peak oxygen uptake and V E (r = 0.57, p < 0.001) was found. Conclusions: Ventilatory response plays a role in the assessment of exercise capacity in elite soccer players.
