Ergospirometry: The following parameters were analyzed: Ergospirometry (Ergo), Maximum heart rate (HRmax), Maximum oxygen consumption (VO2max) and Anaerobic threshold (LA). The ergospirometric data were obtained through the Centurion 200 Treadmill and Micromed® BRA ECG. Protocol: start with 10 km/h - 1% inclination and increase of 1 km every minute. Gas analyzer: Vmax, Encore 29 c, Sensormedics®, USA. Program 20-21. Gases in two torpedoes: (1) - oxygen (O2); 26% and (2) - Carbon Dioxide (CO2): 4%, oxygen (O2) = 16% and Nitrogen (N2).
