Influence of AMY1 gene copy number on salivary amylase activity changes induced by exercise in young adults.
Article in Physiological reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

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 quantified using RT-PCR. Results showed a significant increase in amylase activity postexercise. Additionally, amylase activity pre- and post-exercise was positively correlated with AMY1 copy number. The generalize linear model showed that the exercise-induced increase in amylase activity per AMY1 gene was negatively related to the AMY1 copy number and aerobic fitness. Gender has no effect on amylase activity. These results suggest a different mechanism for the constitutive and exercise-induced amylase secretion, while aerobic fitness may be independently involved in the secretion.
