SUNDAY, Oct. 31 (HealthDay News) -- Heat acclimation helps
improve athletes' performance in both hot and cool environments, a
new study has found.
University of Oregon researchers found that highly trained
cyclists who underwent a 10-day heat acclimation program achieved
increases of about 7 percent in performance tests under both hot
and cool conditions. In terms of competitive cycling, this is a
The performance increase in hot conditions was expected but this
is the first study to show that heat acclimation can improve
athletic performance in cool conditions.
"Our findings could have significant impacts in the competitive sports world," study author Santiago Lorenzo said in a university news release.
The findings are published in the October issue of the
Journal of Applied Physiology.
Heat acclimation improves several bodily functions, including
the ability to control body temperature and sweating. It also
boosts blood flow through the skin and expands blood volume, which
