What is one effect of circadian dysrhythmia on athletes?

Circadian dysrhythmia refers to disruptions in the normal sleep-wake cycle, which can significantly affect an athlete's physical and mental performance. When an athlete experiences this type of circadian disruption, it can lead to impaired exercise performance due to various factors.

One major impact is the negative effect on sleep quality and duration. Poor sleep can result in increased levels of fatigue, reduced reaction times, and decreased motivation, all of which are critical for optimal athletic performance. Additionally, circadian dysrhythmia can interfere with hormonal regulation, including those hormones involved in muscle recovery and energy production, further hindering performance capabilities during training and competition.

In contrast, options such as improved performance, decreased metabolism, and enhanced concentration do not align with the established effects of circadian dysrhythmia. Athletes experiencing this condition are unlikely to find improvements in their physical output, and both metabolism and cognitive function typically suffer rather than benefit, making impaired exercise performance a direct and observable consequence of circadian dysrhythmia.
