Abstract
Electroencephalograph activity, particularly alpha and beta waves, reflect key aspects of brain function. Alpha waves are associated with relaxation and a calm, wakeful state, while beta waves indicate mental engagement, active thinking and arousal. These waves provide valuable insights into the dynamic balance between relaxation and cognitive effort. Physical activity has been recognized for its role in improving brain health, enhancing neuroplasticity and cognitive performance. Exercise has been shown to modulate alpha and beta electroencephalograph (EEG) rhythms, which are associated with cognitive and emotional states. This study seeks to explore the immediate impact of physical exercise on these brainwave patterns, contributing to a deeper understanding of the brain’s responses to exercise. To analyze the effect of acute exercise on alpha and beta electroencephalograph activity, exploring the neurophysiological alterations induced by physical activity. This study included 50 physically active, healthy subjects of 21‐30 years of age. Anthropometric parameters were recorded. Pre‐exercise EEG was recorded after 10 minutes of rest. Then the subjects were instructed to do cycling in cycle ergometer until voluntary exhaustion. Immediately after exercise, Post‐exercise EEG was recorded. SPSS Software‐23 version was used. Paired t test was used for analysis. p value < 0.05 was considered to be significant. Initially at rest, the subjects had increased beta wave amplitude i.e. in pre‐exercise EEG. This indicates the heightened mental alertness and cognitive engagement. Later on, after completing the cycle ergometer exercise, their post‐exercise EEG showed a significant increase in alpha wave amplitude and a decrease in beta wave amplitude mainly in occipital and parietal leads, indicating reduced mental alertness and increased relaxation. This study found that acute exercise increased alpha and decreased beta activity, suggesting a relaxed yet alert mental state. These findings highlight the potential of exercise to positively influence the brain function and mental health.
