Twenty male esports players were randomised to cup stacking three days weekly for four weeks or usual training. Post-intervention salivary alpha-amylase fell within the experimental group and differed significantly from controls.
Key findings
- Baseline values were 51.20±7.25 versus 46.20±7.57 KU/L. Significant within- and between-group post-test differences were reported at p
Why this matters globally
Training and competition stress is a global esports issue; a coordination-based active break is a low-cost candidate for further testing.
Thai researcher contribution
Researchers from RMUTI, Surindra Rajabhat and Khon Kaen University linked sport science, biomarkers and Thai university esports.
Limitations to consider
The tiny all-male single-site sample had baseline imbalance. Allocation concealment, masking and adherence are unclear, and alpha-amylase is sensitive to timing, diet, caffeine and collection.
