Cardiac remodeling in amateur triathletes after 24 weeks of exercise training for a half-Ironman event: a brief report.

Changes in cardiac remodeling in response to an exercise program for a half-ironman are not homogeneous across the ventricles and are influenced by participants' past-training experience. This study strengthens our knowledge of extreme exercise training for a half-ironman to further develop better training programs and medical follow-up in amateur triathletes.
