Brief Summary

All the study participants performed the Wingate Anaerobic Test (WAnT) with maximal effort. The experimental group (E) performed a 3-minute recovery protocol based on low-intensity breathing Voluntary Isocapnic Hyperpnea exercises 20 minuter after cessation of the exercise, whereas the control group (C) used passive recovery only. All study participants were advised to sit during the 30-minute period, with minimal walking in order to meet the physiological needs allowed. The blood samples were taken 3 minutes and 30 minutes after cessation of the exercise to measure the bLa. The Borg CR-10 Scale was presented to the participants 3 minutes and 30 minutes after cessation of the exercise to measure the rate of perceived exertion (RPE) (Borg, 1998).

Outcome Measures

Primary Outcomes (2)

• Changes in blood lactate (bLa)

  The blood samples were taken 3 minutes and 30 minutes after cessation of the exercise to measure the bLa. Blood samples were taken from fingertips by skilled technicians to 20 uL capillary tubes. bLa was measured with Super GL2 analyzer (Dr. Müller Gerätebau GmbH, Freital, Germany).

  30 minutes

• Changes in rate of perceived exertion (RPE)

  The Borg CR-10 Scale was presented to the participants 3 minutes and 30 minutes after cessation of the exercise to measure the rate of perceived exertion (RPE) (Borg, 1998).

Interventions

Voluntary Isocapnic Hyperpnea BEHAVIORAL

The protocol of 3' of breathing with 20 breaths·min-1 frequency. The Isocapnic BreathWayBetter devices (Isocapnic Technologies Inc, Kelowna, Canada) with 6-liter bags were used. The protocol was performed in a seating position.
