Transcutaneous electrical acupoint stimulation alleviates adverse cardiac remodeling induced by overload training in rats.

Rigorous exercise may compromise heart function. Our study has found that overload training exercise in rats was associated with adverse cardiac remodeling and increased myocardial apoptosis, fibrosis, and autophagy. Transcutaneous electrical acupoint stimulation (TEAS), a traditional Chinese medical technique, could counteract the deleterious effects of overload training on the heart. These findings highlight the significance and potential applications of TEAS in preventing cardiac dysfunction induced by rigorous exercise.
