The Claim

In amateur athletes, physical fatigue induced by isokinetic exercise and a 20-minute treadmill run is associated with improved visual reaction time across morning, afternoon, and evening sessions, with a statistically significant main effect (p = 0.002).

In plain English

Amateur athletes who experience physical fatigue from isokinetic exercise and a 20-minute treadmill run show faster visual reaction times during morning, afternoon, and evening sessions.

See the scientific wording

In amateur athletes, physical fatigue induced by isokinetic exercise and a 20-minute treadmill run is associated with improved visual reaction time, with a statistically significant main effect observed across morning, afternoon, and evening sessions (p = 0.002), suggesting that acute neuromuscular fatigue may enhance certain aspects of cognitive processing related to rapid visual-motor responses.

Why this might work

When the body gets tired from intense exercise, it releases a chemical called BDNF that makes the brain's decision-making area more active. This helps the brain process visual signals faster and trigger a quick response, making reaction times shorter.

  1. Study: Circadian Rhythm and Physical Fatigue Separately Influence Cognitive and Physical Performance in Amateur Athletes

    After working out hard, these athletes got faster at responding to visual signals, no matter if it was morning, afternoon, or evening. Their fatigue made them react quicker, not slower.
