SILVA, Paulo Roberto Santos et al. Ventilatory threshold profile during exercise and peak oxygen uptake verified in female soccer players. Rev Bras Med Esporte [online]. 1999, vol.5, n.4, pp. 132-137. ISSN 1517-8692. http://dx.doi.org/10.1590/S1517-86921999000400003.
Thirty-seven female soccer players aged 21.5 ± 5.9, weight 57.0 ± 8.3 kg, height 161 ± 7 cm and body mass index 21.8 ± 2.1 kg/m2 were submitted to spirometric and metabolic evaluation by a computerized analysis system of expired gases (model Vmax 29c, SensorMedics, EUA). Cardiovascular response was recorded by means of a computerized ECG (model 6.4, HeartWare, BRA). Maximum physical capacity was evaluated by a treadmill test (model ATL 10.100, Inbramed, BRA), using incremental continuous protocol. The parameters and results were: in ventilatory threshold 1 (VT1): VO2 = 30.5 ± 3.7 ml O2.kg-1.min-1; %VO2 = 64 ± 7%; running velocity = 8.1 ± 0.3 km.h-1; HR = 154 ± 9 bpm; in ventilatory threshold 2 (VT2): VO2 = 40.9 ± 4.5 ml O2.kg-1.min-1; %VO2 = 85.7 ± 4.9%; running velocity = 11.4 ± 1.1 km.h-1; HR = 179 ± 7 bpm. The peak VO2 was 47.4 ± 4.1 ml O2. kg-1.min-1. In conclusion, the ventilatory thresholds and the aerobic power verified in female soccer players are physiological parameters of great importance, as they make it possible to enlarge their practical application, qualifying, controlling and developing the physical training of such athletes in a more practical and objective manner.
