Circulating catecholamines, endothelin-1, and nitric oxide releases do not explain the preserved FMD following acute resistance exercise in strength-trained men

Purpose Acute resistance exercise decreases endothelial function in sedentary individuals but not in strength-trained (ST) individuals. However, the underlying mechanism(s) of vascular protection in ST individuals remains unclear. Herein, we compared catecholamines, endothelin-1 (ET-1), and nitric o...

Description
Summary:Purpose Acute resistance exercise decreases endothelial function in sedentary individuals but not in strength-trained (ST) individuals. However, the underlying mechanism(s) of vascular protection in ST individuals remains unclear. Herein, we compared catecholamines, endothelin-1 (ET-1), and nitric oxide (NOx) releases after acute resistance exercise between sedentary and ST individuals. Methods The untrained (UT) group comprised 12 male individuals with no regular training, while the ST group comprised 12 male individuals. Participants performed a session of resistance exercise, which consisted of 3 sets of 10 repetitions at 75% of one repetition maximum. Heart rate (HR) and blood pressure were measured during resistance exercise. Brachial artery flow-mediated dilation (FMD), blood pressure, HR, and blood collection were undertaken before and 10, 30, and 60 min after the resistance exercise. Results No significant difference was found in baseline brachial artery FMD between the groups ( P  > 0.05). Brachial artery FMD was significantly reduced in the UT group ( P
