Background The purpose of this study was to investigate irisin and myostatin responses to acute high-intensity interval exercise. Materials and methods Ten male professional kick-boxers aged between 18 and 24 years and 10 sedentary males with similar age and body weight participated in the present study. Participants performed 4 × 30-s Wingate test separated with 4 min of rest. Blood samples were taken immediately before and after exercise, and 3 and 6 h of recovery. Results and conclusion At rest, irisin levels were higher in the kick-boxers (p < 0.05). Immediately after the exercise, irisin levels were decreased in both groups (p < 0.05). A trend toward a return to baseline appeared after 3 h of recovery in the kick-boxers (p < 0.05). At rest, myostatin concentrations were not different between the groups (p > 0.05). Immediately after the exercise, myostatin levels were increased in both groups (p < 0.05). A trend toward a return to baseline appeared after 3 h of recovery in the kick-boxers (p < 0.05). Acute high-intensity interval exercise decreased irisin levels and increased myostatin levels.
背景 本研究旨在调查鸢尾素和肌肉生长抑制素对急性高强度间歇运动的反应。材料与方法 10名年龄在18至24岁之间的男性职业搏击运动员和10名年龄及体重相近的久坐不动男性参与了本研究。参与者进行了4次30秒的温盖特测试，每次测试间隔4分钟休息时间。在运动前、运动后以及恢复3小时和6小时后采集血样。结果与结论 休息时，搏击运动员的鸢尾素水平较高（p<0.05）。运动后即刻，两组的鸢尾素水平均下降（p<0.05）。搏击运动员在恢复3小时后有恢复至基线水平的趋势（p<0.05）。休息时，两组间肌肉生长抑制素浓度无差异（p>0.05）。运动后即刻，两组的肌肉生长抑制素水平均升高（p<0.05）。搏击运动员在恢复3小时后有恢复至基线水平的趋势（p<0.05）。急性高强度间歇运动降低了鸢尾素水平并升高了肌肉生长抑制素水平。
