Fatigue-related impairment in the speed, accuracy and variability of psychomotor performance: comparison with blood alcohol levels
Cognitive performance is impaired by fatigue arising from sustained wakefulness and alcohol. Three recent papers directly compared the effects of increasing fatigue and blood alcohol concentration (%BAC) to provide a framework for understanding fatigue-related cognitive impairment. […]
Heart rate variability and cognitive function: Effects of physical effort
This study investigated alterations in heart rate variability (HRV) and cognitive performance before and after physical effort, for 30 high-level track and field athletes (23 males and 7 females). Interbeat intervals were assessed at the baseline […]
