This study aims to characterize the aerobic and anaerobic metabolic demands (alactic and lactic) in goalball athletes. For this, we divided it into two steps: 1) the participants will undergo a progressive treadmill test, for determining the anaerobic threshold (AT), maximal oxygen uptake (VO2max), five submaximal tests (50- 95% of VO2max) and a supra-maximal exercise (110% VO2max) to estimate the maximal accumulated oxygen deficit (MAOD). In the second stage, a simulated goalball game protocol will be performed to analyze the metabolic demands for a game divided into seven moments: M0 (rest); M1 (after 4 minutes of play); M2 (after 8 minutes of play); M3 (after 12 min game - half-time); M4 (after 16 minutes of play); M5 (after 20 minutes of play); M6 (after 24 minutes of game - Game end). At each time point we will collectec 25 ml of blood from the ear lobe for the determination of lactate and analysis of exhaled air through the back extrapolation techniques to estimate the VO2 at all times. It will also be evaluated time offensive effort, with regard to the time intervals of the throws executed by athletes, through systematic observation of vídeos recorded.
