Physical Exhaustion Induced Variations in Event-Related Potentials and Cognitive Task Performance in Young Adults.

Background/aims: Physical exhaustion is not always peripheral, and it is the brain that causes the sensation of fatigue either due to decrease of metabolic resources or due to central activation process that regulates attention and performance. This study was undertaken to observe the variations in event-related potentials (ERPs) and cognitive performance after an exhausting physical exercise.

Methods: A total of 60 healthy young adult subjects were included in the study.

Short-term acute effects of gutkha chewing on heart rate variability among young adults: A cross-sectional study.

Background And Objectives: An increase in the consumption of smokeless tobacco has been noticed among high school, college students, and adults. Despite the antiquity and popularity of chewing tobacco in India, its effects have not been investigated systematically in humans. The aim of this study was to investigate acute effects of gutkha chewing on heart rate variability (HRV) among healthy young adults.
