Description
Mehmet Emin Yelken and six colleagues test, in a 2026 trial, whether adding brain-body coordination drills to ski training changes stress and immune markers in teenage skiers. Twenty under-14 female cross-country skiers were split into two groups of ten. One skied as usual, forty-five minutes three times a week. The other added Life Kinetics exercises, which pair movement with mental tasks, for the same eight weeks.
Saliva was sampled before and after. Cortisol, the classic stress hormone, did not budge in either group. A second enzyme, alpha-amylase, differed between groups overall without a clear time pattern. The clearest signal was immune: a protective antibody in saliva rose in the drill group and fell in controls over the program. The authors judge the added training gentle on stress systems, while urging bigger, longer studies before claiming immune benefit.
