Abstract:

BACKGROUND: In the condition of exercise physiology, adenosine triphosphate-sensitive potassium (KATP) channel plays an important role in many aspects, such as regulation of coronary artery tension, exercise-induced myocardial protection effect and delay of skeletal muscle fatigue.

OBJECTIVE: To review and investigate the role of KATP in exercise in order to provide theoretical reference for understanding mechanism underlying exercise regulation of body’s metabolism.
METHODS: A computer-based online search of PubMed and VIP databases was performed for articles related to molecular structure, biological function and regulatory role of KATP as well as correlation of KATP with coronary artery, myocardium, skeletal muscle fatigue and exercise ability published from January 1991 to June 2014. The keywords were “KATP channels; adenosine triphosphate; sports; myocardium; ion channels” in English and Chinese, respectively. Finally, 42 relevant articles were included in result analysis.
RESULTS AND CONCLUSION: Coupling with cellular energy metabolism and cell membrane excitability, KATP channel is one of the effectors for myocardial protection in response to various physiological and pathological stresses. Prolonged endurance training can increase the expression of skeletal muscle and myocardial KATP, which may be an adaptive performance of the myocardium and skeletal muscle in response to exercise stress. KATP may participate in regulation of coronary blood flow. Myocardial KATP plays an important protective role for alleviating myocardial ischemia-reperfusion injury induced by exercise. When skeletal muscle fatigue occurs, the activation of KATP is helpful to prevent muscle fiber damage and cell death due to excessive consumption of ATP, in favor for the fast recovery from fatigue. The relation between KATP and exercise ability still needs further research.
