AI Article Synopsis
- The study aimed to assess if standardized exercise tests can effectively evaluate adrenal response by measuring salivary cortisol levels in healthy prepubertal children.
- During exercise tests (cycling and a running shuttle), cortisol levels showed no change or decrease immediately after, but increased significantly after the shuttle-run test at 15 minutes, indicating different responses based on the type of exercise.
- The findings suggest that the shuttle-run test could be a practical, non-invasive way to evaluate adrenal response in healthy prepubertal children, as opposed to cycling tests which did not show the same increase in cortisol.
Article Abstract
Objective: To determine the feasibility of non-invasive evaluation of adrenal response in healthy prepubertal children by standardized exercise tests.
Methods: On separate occasions, healthy prepubertal children performed a submaximal cycling test, a maximal cycling test, and a 20-m shuttle-run test. Salivary cortisol levels were determined before exercise, and 1 and 15 min after exercise.
Results: Immediately after cessation of the cycling and shuttle-run tests, salivary cortisol levels remained unchanged or decreased. Fifteen minutes after the shuttle-run test, salivary cortisol levels increased significantly. This increase in salivary cortisol levels was not observed 15 min after the cessation of the cycling tests.
Conclusion: The results of this study demonstrate a different response in salivary cortisol levels after standardized cycling and running tests in prepubertal children. The increase in salivary cortisol levels found after a short standardized running test suggests that this may be a practical non-invasive method for evaluating adrenal response in healthy prepubertal children.
