Design outcomes

Primary

Measure	Time frame
Change in maximum and average power (measured in watts) during 10s sprint intervals.	—

Secondary

Measure	Time frame
Secondary endpoints will be changes in blood lactate concentration, muscular oxygen saturation (total hemoglobin [tHb], oxygenated hemoglobin [O2Hb], deoxygenated hemoglobin [HHb], muscle activity (operationalized by EMG), and subjective sensation / perceived fatigue (effort perception, body signals, mood, arousal, and exhaustion-fatigue).	—
