Abstract
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 est…
