Fatigue increases injury risk by what mechanism, and which management strategies help mitigate it?

• A. Fatigue impairs neuromuscular control and technique; mitigate with periodized training, adequate recovery, load monitoring, and sleep.
• B. Fatigue increases VO2 max; mitigate with extra cardio sessions.
• C. Fatigue has no effect; mitigation is unnecessary.
• D. Fatigue only affects motivation; mitigate with incentives.

Answer: (A)

Fatigue increases injury risk because it compromises neuromuscular control and movement technique. When fatigued, the timing and force of muscle contractions become less precise, reaction times slow, and proprioceptive feedback is dampened. This can alter mechanics during high‑risk actions such as cutting, landing, or sprinting, leading to less joint stability and poorer movement patterns that heighten the chance of strains, sprains, and overuse injuries.

Mitigation focuses on training structure and recovery. Periodized training helps avoid sudden spikes in workload, allowing gradual adaptations so the body can cope with higher demands without becoming excessively fatigued. Adequate recovery between sessions gives muscles, tendons, and the nervous system time to repair and reset, preserving technique and coordination. Load monitoring tracks the actual stress placed on the body and the athlete’s readiness, enabling adjustments to prevent overreaching. Sleep is essential for central nervous system recovery, hormonal balance, and tissue repair, all of which support better neuromuscular control and technique.

Fatigue does not increase VO2 max, and addressing fatigue is not about adding more cardio sessions alone. Fatigue affects more than motivation; it impacts coordination, judgment, and movement quality, all of which influence injury risk.
