四周常压模拟高住低练对女子赛艇运动员血清睾酮、皮质醇及血睾酮／皮质醇的影响 总被引：6，自引：2，他引：4
目的:探讨4周常压模拟高住低练训练法对女子赛艇运动员血清睾酮、皮质醇及血睾酮/皮质醇等的影响。方法:系统观察了7名女子赛艇运动员(实验组)进行4周高住低练(2500m)训练前、训练期间第1周、第2周、第4周及训练后第1周和第2周这些指标的变化,并与6名低住低练运动员(对照组)进行比较分析。结果:(1)4周高住低练使女子赛艇运动员血清T水平呈先降后升之势,4周结束后仍低于实验前水平,并且至少持续2周;(2)4周高住低练期间运动员血清皮质醇水平降低,实验结束后2周恢复到实验前水平;(3)4周高住低练期间Hb和RBC的变化与T和T/C的变化并不一致,实验前后比较,前两者总体趋势是升高,而后两者总体趋势是下降。结论:4周高住低练使血清T水平先降后升,血清C水平降低,这可能与低氧刺激导致血液Hb和RBC逐渐升高以及机体合成代谢相对增强有关。 相似文献

研究迷迭香对大强度耐力训练大鼠血清睾酮和肾上腺皮质激素的影响。方法:本实验选用SD大鼠,建立大强度耐力训练模型,训练结束测定其血清睾酮和肾上腺皮质激素。结果:大强度耐力训练可使大鼠血清睾酮下降,皮质醇水平上升,睾酮/皮质醇(T/C)值下降,说明大强度耐力训练已造成大鼠机体神经内分泌系统机能紊乱,使大鼠体内的分解代谢持续加强。服用迷迭香后大鼠血清睾酮水平均明显高于其相应的对照组,T/C值明显升高;服用迷迭香的大强度耐力训练组大鼠血清皮质醇水平明显下降。结论:服用迷迭香可以促进大强度耐力训练后大鼠合成代谢加强,有利于能量物质的储存,促进运动性疲劳的恢复。 相似文献

大负荷训练对男子柔道运动员血清睾酮、皮质醇及血红蛋白的影响 总被引：11，自引：0，他引：11
本文通过对5名山西省男子柔道运动员冬训大负荷训练期血清睾酮(T)、皮质醇(C)、血红蛋白(Hb)、血球压积(HCT)的测试分析表明大负荷训练使男子柔道运动员的T、T/C值显著下降(P＜0.05)，5名运动员表现出程度不同的运动疲劳，C值变化不明显(P＞0.05)。柔道运动员大负荷训练期的Hb、HCT与其基础值之间没有显著意义(P＞0.05)。提示，T、C、T/C及Hb是男子柔道运动员大负荷训练期机能评定的有效指标，对防止运动员过度疲劳、及早发现和预防运动员潜在性贫血具有较高的参考价值。 相似文献

PurposeThe purpose of this study was to evaluate the changes in some hormonal parameters (cortisol, testosterone, ratio of testosterone/cortisol (T/C)) in professional soccer players during a season.MethodsFifteen professional players from a soccer club of the first division of the Greek soccer league participated. All sport medical examinations were conducted four times: before the re-building period, post re-building period, mid-season, and after finishing the competition phase.ResultsFor testosterone, significant differences were observed between the end season and post re-building period (11.6%; p < 0.05) and mid-season (12.1%; p < 0.05). The cortisol concentration increased at mid-season by approximately 23%, and this change differed significantly from all other measurements for this hormone. The T/C ratio increased at the post re-building period and decreased at the middle of the season.ConclusionThese hormones and their ratios could be used as stress and recovery state indicators. Coaches can use these parameters in combination with other indicators to optimize workloads, and to avoid overreaching and overtraining. 相似文献

AbstractThe aim of this study was to examine the acute response to plasma and salivary cortisol and testosterone to three training protocols. Ten trained endurance athletes participated in three experimental trials, such as interval training (INT), tempo run (TEMP) and bodyweight-only circuit training (CIR), on separate days. Blood and saliva samples were collected pre- and 0, 15, 30 and 60 min post-exercise. Peak post-exercise salivary cortisol was higher than pre-exercise in all trials (P < 0.01). After INT, salivary cortisol remained elevated above pre-exercise than 60 min post-exercise. Salivary testosterone also increased post-exercise in all trials (P < 0.05). Plasma and salivary cortisol were correlated between individuals (r = 0.81, 0.73–0.88) and within individuals (r = 0.81, 0.73–0.87) (P < 0.01). Plasma and salivary testosterone was also correlated between (r = 0.57, 0.43–0.69) and within individuals (r = 0.60, 0.45–0.72), (P < 0.01). Peak cortisol and testosterone levels occurred simultaneously in plasma and saliva, but timing of post-exercise hormone peaks differed between trials and individuals. Further investigation is required to identify the mechanisms eliciting an increase in hormones in response to CIR. Furthermore, saliva is a valid alternative sampling technique for measurement of cortisol, although the complex, individual and situation dependent nature of the hormone response to acute exercise should be considered. 相似文献

The purpose of this study was to investigate the responses of salivary hormones and salivary secretory immunoglobulin A (SIgA) and anxiety in winners and losers during an international judo competition. Twenty-three trained, male, national-level judo athletes provided three saliva samples during a competition day: morning, in anticipation of competition after an overnight fast, mid-competition, and post-competition within 15 min post-fight for determination of salivary cortisol, salivary testosterone, salivary testosterone/cortisol ratio, SIgA absolute concentrations, SIgA secretion rate and saliva flow rate. The competitive state anxiety inventory questionnaire was completed by the athletes (n = 12) after the first saliva collection for determination of somatic anxiety, cognitive anxiety and self-confidence. Winners were considered 1-3 ranking place (n = 12) and losers (n = 11) below third place in each weight category. Winners presented higher anticipatory salivary cortisol concentrations (p = 0.03) and a lower mid-competition salivary testosterone/cortisol ratio (p = 0.003) compared with losers with no differences for salivary testosterone. Winners tended to have higher SIgA secretion rates (p = 0.07) and higher saliva flow rates (p = 0.009) at mid-competition. Higher levels of cognitive anxiety (p = 0.02) were observed in the winners, without differences according to the outcome in somatic anxiety and self-confidence. The results suggest that winners experienced higher levels of physiological arousal and better psychological preparedness in the morning, and as the competition progressed, the winners were able to control their stress response better. 相似文献

Abstract In this study, we investigated the effect of 1- and 3-week tapering periods on concentrations of plasma testosterone (T), cortisol (C), T/C ratio, mood state, and performance in elite male cyclists. After 8 weeks of progressive training, cyclists were randomly assigned to a control group (n=12) who continued performing intense training for a further 3 weeks, or a taper group (n=12) who continued with a 50% reduction in training volume. Blood testosterone and cortisol concentrations were assayed and the T/C ratio calculated from analysis obtained via standard ELISA. Mood state was determined using the Profile of Mood States (POMS) questionnaire. All data were collected immediately after a 40-km time-trial performed before, during, and after the 8-week training protocol and after the 1- and 3-week tapering/training periods. In the taper group, 40-km time-trial time decreased significantly (P<0.01) and equally for both the 1- and 3-week taper periods relative to the control group. There were significant elevations in T/C ratio (P<0.001) and reductions in cortisol concentrations and POMS scores in the taper group relative to the control groups at the end of both the 1- and 3-week tapering periods. Hence, taper periods are effective in improving performance and mood state and elevating the blood T/C ratio. 相似文献
