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

The Utility and Validity of a High-intensity, Intermittent Exercise Protocol in Male Jumping Athletes

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.

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.

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
