Physical

Evidence indicates a clear negative impact on endurance-based tasks. Mixed evidence exists around ‘all-out’ maximal strength, power and anaerobic tasks.

• Decreased time to exhaustion.
• Decreased self-selected power output.
• Increased completion time. Example, Cycling (time-trial, time to fatigue), Swimming (100m, 200m, 1500m), and Running (3km, 5km, Yo-Yo IRT, beep test).
• Decreased distance covered during small-sided games.
• Decreased resistance training volume completion.
