The purpose of this investigation was to examine the acute hormonal response to the kettlebell swing exercise. Ten recreationally resistance trained men (age, 24 ± 4 years; height, 175 ± 6 cm; body mass, 78.7 ± 9.9 kg) performed 12 rounds of 30 seconds of 16 kg kettlebell swings alternated with 30 seconds of rest. Blood samples were collected before (PRE), immediately after (IP), and 15 (P15) and 30 minutes after exercise (P30) and analyzed for testosterone (T), immunoreactive growth hormone, cortisol (C), and lactate concentrations. Heart rate and rating of perceived exertion were measured at the end of each round. Testosterone was significantly higher (p ≤ 0.05) at IP than at PRE, P15, or P30 (PRE: 28 ± 3; IP: 32 ± 4; P15: 29 ± 3; P30: 27 ± 3 nmol·L). Growth hormone was higher at IP, P15, and P30 than at PRE (PRE: 0.1 ± 0.1; IP: 1.8 ± 1.2; P15: 2.1 ± 1.1; P30: 1.6 ± 1.3 μg·L). Cortisol was higher at IP and P15 than at PRE and P30 (PRE: 617 ± 266; IP: 894 ± 354; P15: 875 ± 243; P30: 645 ± 285 nmol·L). Lactate was higher at IP, P15, and P30 than at PRE (PRE: 1.1 ± 0.5; IP: 7.0 ± 3.0; P15: 4.0 ± 2.7; P30: 2.5 ± 1.8 mmol·L). Heart rate increased progressively from 57 ± 12 at PRE to 170 ± 10 at IP. The exercise protocol produced an acute increase in hormones involved in muscle adaptations. Thus, the kettlebell swing exercise might provide a good supplement to resistance training programs.
本研究的目的是检测壶铃摆动练习引起的急性激素反应。十名有休闲抗阻训练经验的男性（年龄24±4岁；身高175±6厘米；体重78.7±9.9千克）进行12组16千克壶铃摆动，每组30秒，组间休息30秒。在运动前（PRE）、运动结束即刻（IP）、运动后15分钟（P15）和30分钟（P30）采集血样，分析睾酮（T）、免疫反应性生长激素、皮质醇（C）和乳酸浓度。在每组结束时测量心率和主观用力程度评级。睾酮在IP时显著高于PRE、P15或P30（PRE：28±3；IP：32±4；P15：29±3；P30：27±3纳摩尔/升）。生长激素在IP、P15和P30时高于PRE（PRE：0.1±0.1；IP：1.8±1.2；P15：2.1±1.1；P30：1.6±1.3微克/升）。皮质醇在IP和P15时高于PRE和P30（PRE：617±266；IP：894±354；P15：875±243；P30：645±285纳摩尔/升）。乳酸在IP、P15和P30时高于PRE（PRE：1.1±0.5；IP：7.0±3.0；P15：4.0±2.7；P30：2.5±1.8毫摩尔/升）。心率从PRE时的57±12逐渐增加到IP时的170±10。该运动方案使参与肌肉适应的激素急性增加。因此，壶铃摆动练习可能为抗阻训练计划提供良好补充。
