Utility and Validity of a High-intensity, Intermittent Exercise Protocol

Not Applicable

Completed

• Conditions: Fatigue
• Interventions: Other: Fatigue protocol

• Registration Number: NCT04531891
• Lead Sponsor: University Ghent

Brief 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.

Detailed 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.

Primary Outcome Measures

Name	Time	Method
Isokinetic dynamometry	This parameter will be monitored 30 minutes after completion of the protocol	Isokinetic dynamometry of the quadriceps muscle
Heart rate	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
BORG	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	This parameters will be monitored 10 minutes after completion of the protocol	Blood lactate level, expressed in millimol per liter
