Clinical trial NCT04531891: Utility and Validity of a High-intensity, Intermittent Exercise Protocol
Official title: The Utility and Validity of a High-intensity, Intermittent Exercise Protocol in Male Jumping Athletes
Study type: INTERVENTIONAL
Overall status: COMPLETED
Phase: NA
Conditions: Fatigue
Lead sponsor: University Ghent
Sponsor class: OTHER
First posted: 2020-08-31
Enrollment: 20
Sex: MALE
Minimum age (years): 18
Maximum age (years): 45
Standard ages: ADULT
Accepts healthy volunteers: yes
Allocation: RANDOMIZED
Intervention model: CROSSOVER
Intervention model description: Each participant will randomly be assigned to two different fatigue protocols, on separate days. The first protocol is a high-intensity, intermittent exercise protocol and will be performed until complete exhaustion. The second protocol is a time-based variant of the previous protocol and will be performed during 5 minutes.
Primary purpose: SCREENING

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.

Eligibility criteria: Inclusion Criteria:

* Men
* ≥ 18 years
* Volley- and basketball, non-elite
* ≥ 3 times per week sports participation
* No acute or overuse low back/lower extremity injuries in the past 6 months

Exclusion Criteria:

* Women
* \<18 years
* \>45 years
* other sports than volley- and basketball
* elite players
* \<3 times per week sports participation
* acute or overuse low back/lower extremity injuries in the past 6 months
