Clinical Trial Summary

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.

Description:

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.

Intervention

Other:
• Fatigue protocol
During the fatigue protocol, participants will sprint forward 5 m, cut at a 90° angle, sprint forward another 5 m, and backpedal 5 m. This activity will be repeated 4 times before participants will complete a series of hurdle activities. First, they will perform 2-legged jumps over 5 hurdles that are 30 cm high, turn, and repeat the jumps. Second, they will perform side-stepping exercises over the 5 hurdles. Third, they will complete four 5-m lateral shuffles.
