How does fatigue influence decision making in sport?

• A. It enhances attention and reaction time due to adrenaline.
• B. It impairs attention, reaction time, working memory, and judgment, reducing decision quality and performance.
• C. It only affects physical stamina, not cognitive processes.
• D. It improves strategic planning by conserving energy.

Answer: (B)

Fatigue diminishes the brain’s ability to process information during sport, which directly undermines decision making. When tired, attention becomes less sustained, reaction times slow, working memory struggles to hold multiple options and cues, and judgments become less accurate. All of these declines stack to reduce the quality of decisions and, as a result, overall performance, especially in late-game situations where demands remain high but energy is low. Adrenaline can momentarily raise arousal, but it does not offset the broad cognitive declines that fatigue brings, so the idea of enhanced attention or faster reactions under fatigue isn’t correct. Fatigue doesn’t just affect physical stamina; its cognitive impact is real and significant, and the notion that it improves strategic planning by conserving energy isn’t supported. In practice, training that includes decision-making under fatigue, deliberate recovery, and routines to maintain focus helps players sustain better choices even when tired.
