简要总结
The purpose of this study is to identify an exercise-induced fatigue protocol to mimic central and peripheral acute fatigue effects associated with participation in vigorous dynamic sports activities and to understand the expected central (cardiovascular) and peripheral (muscular) impact of this protocol.
详细描述
Fatigue-related parameters (BORG, heart rate, blood lactate level, concentric/eccentric force of the quadriceps muscle) will be measured before and after different short-term high-intensity, intermittent exercise protocols.

结局指标
主要结局
Heart rate
时间窗: This parameters will be continuously monitored 10 minutes before the start of the fatigue protocol until 30 minutes after completion of the protocol
Heart rate, expressed in beats per minute
Isokinetic dynamometry
时间窗: This parameter will be monitored 30 minutes after completion of the protocol
Isokinetic dynamometry of the quadriceps muscle
BORG
时间窗: This parameters will be continuously monitored 10 minutes before the start of the fatigue protocol until 30 minutes after completion of the protocol
BORG-score, indicating the rate of perceived exertion for legs and breathlessness
Blood lactate level
时间窗: This parameters will be monitored 10 minutes after completion of the protocol
Blood lactate level, expressed in millimol per liter
次要结局
- Circuit time(Time will be recorded immediately after completion of the fatigue protocol)
