Lactate concentrations were measured in a capillary blood sample obtained fromparticipants' fingertips using a portable analyzer (Lactate 2, Arkray, Kyoto, Japan)
次要结局
- Countermovement jump(At baseline (prior to supplementation) and after exercise (immediately after finishing exercise protocol).)
- Gastrointestinal (GI) symptoms(At baseline (before supplementation), prior to exercise (immediately before beginning exercise protocol), after exercise (immediately after finishing exercise protocol).)
