Abstract

TeamGym is a popular form of gymnastics, including tumbling (Tu), trampette (Tr) and floor exercises (F) characterized by intensive practice placing high levels of stress on athletes. The aim of the study was to investigate athletes' stress-related changes during TeamGym training and competition, considering hormonal and enzymatic responses (i.e., salivary cortisol and alpha-amylase). Ten (5 males and 5 females) TeamGym athletes (age: 22-28 y) were tested twice at the same time before training and competition; furthermore, for excluding circadian effect on hormonal and enzymatic responses, they were tested at the same time during a rest day. Alpha-amylase and cortisol were measured 15 min before the beginning of exercise, after each gymnastic equipment performance, and after thirty minutes from the end of the performance. Factorial ANOVA with repeated measures was used to verify differences between training and competition ( < 0.05). Competition elicited higher values of alpha-amylase than training ( ranging from 0.001 to 0.019) and rest ( ranging from 0.001 to 0.019). Cortisol showed no exercise induced increase, and its concentrations were higher prior to training compared to competition. TeamGym responses confirm other sports findings in stating that competition elicits higher stress response than training and suggest that salivary alpha-amylase is a more sensitive marker than cortisol to psychophysiological stress also in gymnastics intermittent performance.

摘要

团体体操是一种广受欢迎的体操形式,包括翻腾(Tu)、蹦床(Tr)和自由体操(F),其特点是高强度训练,给运动员带来很大压力。本研究的目的是通过考虑激素和酶的反应(即唾液皮质醇和α-淀粉酶),调查团体体操训练和比赛期间运动员与压力相关的变化。十名(5名男性和5名女性)团体体操运动员(年龄:22 - 28岁)在训练和比赛前同时进行了两次测试;此外,为了排除昼夜节律对激素和酶反应的影响,他们在休息日的同一时间进行了测试。在运动开始前15分钟、每次体操器械表演后以及表演结束30分钟后测量α-淀粉酶和皮质醇。采用重复测量的析因方差分析来验证训练和比赛之间的差异(<0.05)。比赛引起的α-淀粉酶值高于训练(范围为0.001至0.019)和休息(范围为0.001至0.019)。皮质醇没有显示出运动诱导的增加,其浓度在训练前高于比赛。团体体操的反应证实了其他运动研究的结果,即比赛引起的压力反应高于训练,并表明唾液α-淀粉酶在体操间歇表演中也是比皮质醇更敏感的心理生理压力标志物。
