Influence of AMY1 gene copy number on salivary amylase activity changes induced by exercise in young adults.

ABSTRACT: Human salivary amylase secretion increases in response to stress; the activity has been reported to rise significantly with high-intensity exercise. The human salivary amylase gene (AMY1) has copy number variation, with the copy number correlating with salivary amylase activity. However, the relationship between individual AMY1 copy number and salivary amylase activity in response to exercise remains unclear. In this study, we investigated AMY1 copy number and fluctuations in amylase activity in 42 healthy university students (25 males and 17 females). Participants engaged in intermittent round-trip interval training on a basketball court. Saliva samples were collected pre- and post-exercise to measure amylase activity. DNA was extracted from the oral mucosa, and AMY1 copy number was quant
