CrossFit Experience Attenuates Heart Rate Variability.

PURPOSE:CrossFitTM (CF) is an exercise modality that consists of varied functional movements performed at high intensity. Minimal empirical evidence exists regarding stress markers (i.e. heart rate variability (HRV)) for this training modality. HRV can be used to indirectly measure alterations in vagal tone and subsequently disruption to homeostasis.The purpose of this study was to evaluate differences in HRV based on CF experience METHODS:Two...
