研究表明,定量负荷运动后血清氨基酸(丙氨酸、酪氨酸、苯丙氨酸、亮氨酸及异亮氨酸)显著升高。注射HCG(绒毛膜促性腺激素)组唾液睾酮含量显著高于未注射HCG组,同时发现运动后五种氨基酸值均显著低于未注射HCG组。证实急性运动使人体蛋白质分解代射增强,睾酮具有明显的抗蛋白质分解作用。 相似文献

长跑锻炼对老年人唾液睾酮的影响 总被引：1，自引：1，他引：0
人体衰老过程中,内分泌系统发生一系列退化。一般认方,男性50岁以后下丘脑—垂体—性腺轴功能开始减退,血浆总睾酮(T)及游离T水平下降,并随年龄的增长而逐渐降低。有文献报道,一些经常参加体育锻炼的老年人,血浆T安静值与成年人相似。本文试图了解经长期长跑锻炼的老年人,在安静状态下唾液T浓度以及在一次定量负荷运动时唾液T浓度的变化。 相似文献

运动性低血睾酮与肾阳虚大鼠能量代谢的比较研究 总被引：2，自引：0，他引：2
以大鼠为对象,用长期大强度、较长时问游泳造成运动性低血睾酮,以0．5％腺嘌呤喂饲造成肾阳虚．并就两种状态下大鼠体内糖储备及骨骼肌能量代谢进行了探讨。结果表明：运动性低血睾酮大鼠肝、肌糖原含量均增加,而且骨骼肌无氧供能的CK、PK活性没有改变,但MDH活性明显升高(P(O．05)。肾阳虚则造成体内肝、肌糖原的明显减少(P<0、05),骨骼肌中CK活性的显降低(P<0．05)．但对骨骼肌中PK及MDH的活性则没有影响。可以认为,肾阳虚及运动性低血睾酮在对大鼠能量代谢影响方面,是两种不同的状态。 相似文献

以大鼠为对象 ,目的在于观察运动性低血睾酮状态下 ,机体血睾酮浓度及骨骼肌蛋白质合成代谢的变化 ,并就补肾中药对上述变化的作用加以研究。结果发现 :运动性低血睾酮状态下 ,大鼠的血清睾酮浓度明显低于对照组 (P<0 .0 5 ) ;服用补肾中药的大鼠则没有明显变化 ;运动性低血睾酮组大鼠股四头肌中α- actin基因表达较正常有所下降 (为正常的 78% ) ,而服用补肾中药则可避免这种下降 (为正常的 10 2 % )。认为 :补肾中药的确可以避免大强度耐力运动造成运动性血睾酮浓度下降及骨骼肌α-actin基因表达受抑的现象。 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 effects of high-intensity intermittent exercise on saliva IgA, total protein and alpha-amylase 总被引：3，自引：0，他引：3
Walsh NP Blannin AK Clark AM Cook L Robson PJ Gleeson M 《Journal of sports sciences》1999,17(2):129-134
The aim of this study was to assess the effect of an acute bout of high-intensity intermittent exercise on saliva IgA concentration and alpha-amylase activity, since this type of training is commonly incorporated into the training programmes of endurance athletes and games players. Eight well-trained male games players took part in the study. They reported to the laboratory after an overnight fast and performed a 60-min cycle exercise task consisting of twenty 1-min periods at 100% VO2max, each separated by 2 min recovery at 30% VO2max. Unstimulated whole saliva was collected over a 5-min period into pre-weighed tubes and analysed for total protein, saliva IgA and alpha-amylase. The saliva flow rate ranged from 0.08 to 1.40 ml x min(-1) at rest and was not significantly affected by the exercise. The performance of the intermittent exercise bout did not affect the saliva IgA concentration, but caused a five-fold increase in alpha-amylase activity (P<0.01 compared with pre-exercise) and a three-fold increase in total protein concentration (P<0.01). These returned to pre-exercise values within 2.5 h post-exercise. It has been suggested that IgA concentration should be expressed as the ratio to total protein concentration, to correct for any concentrating effect due to evaporative loss of saliva water when breathing through the mouth (as in strenuous exercise). The present study clearly demonstrates that this is not appropriate, since there is an increase in salivary protein secretion rate immediately after exercise (571+/-77 microg x min(-1) compared with 218+/-71 microg x min(-1) pre-exercise; P<0.05). The increased saliva alpha-amylase activity after exercise may improve the protective effect of saliva, since this enzyme is known to inhibit bacterial attachment to oral surfaces. The saliva alpha-amylase secretion rate was lower immediately pre-exercise than at any other instant, which may have been due to anticipatory psychological stress, although the subjects were all familiar with interval exercise. This emphasizes the need for true resting non-stressed control conditions in future studies of the effects of exercise on saliva constituents. 相似文献

ABSTRACTThis study investigated the effects of a congested match schedule (7 matches played in 7 days) on steroid hormone concentrations, mucosal immunity, session rating of perceived exertion (S-RPE) and technical performance in 16 elite youth soccer players (14.8 ± 0.4 years; 170.6 ± 9.4 cm; 64.9 ± 7 kg). No change was observed for salivary cortisol concentration across match time points (P = 0.33; effect size [ES] = 0.13–0.48). In contrast, there was a decrease in salivary testosterone and salivary IgA (SIgA) concentrations from the 1st compared with the last time point (P = 0.01 and 0.001, ES = 0.42 and 0.67, respectively). The SIgA concentration varied across time points (P < 0.001) with the highest value observed at the 3rd time point (rest day) (3rd vs all time point; ES = 0.47–0.73). No changes were observed for S-RPE across time points (P > 0.05). A higher number of tackles and interceptions were observed during the 4th match vs 1st and 7th matches (P < 0.001; ES = 2.25 and 1.90, respectively). The present data demonstrate that accumulated fatigue related to participation in a congested match schedule might induce a decrease in testosterone concentration in youth players and negatively affect their mucosal immunity and capacity to perform certain technical actions. 相似文献

The effects of carbohydrate supplementation on immune responses to a soccer-specific exercise protocol 总被引：1，自引：0，他引：1
The aim of this study was to determine the effect of carbohydrate (CHO) versus placebo (PLA) beverage consumption on the immune and plasma cortisol responses to a soccer-specific exercise protocol in 8 university team soccer players. In a randomized, counterbalanced design, the players received carbohydrate or placebo beverages before, during and after two 90 min soccer-specific exercise bouts (3 days apart) designed to mimic the activities performed and the distance covered in a typical soccer match. Blood and saliva samples were collected before, during and after the exercise protocol. Plasma lactate concentration increased to approximately 4 mmol x l(-1) at 45 and 90 min of exercise in both treatments (P<0.01). Plasma glucose concentration was significantly lower after 90 min of exercise with ingestion of the placebo than the carbohydrate (PLA: 4.57+/-0.12 mmol x l(-1); CHO: 5.49+/-0.11 mmol x l(-1); P<0.01). The pattern of change in plasma cortisol, circulating lymphocyte count and saliva immunoglobulin A secretion did not differ between the carbohydrate and placebo trials. Blood neutrophil counts were 14% higher 1 h after the placebo trial than the carbohydrate trial (PLA: 4.8+/-0.5x10(9) cells x l(-1); CHO: 4.2+/-0.5x10(9) cells x l(-1); P = 0.06), but the treatment had no effect on the degranulation response of blood neutrophils stimulated by bacterial lipopolysaccharide. We conclude that, although previous studies have shown that carbohydrate feeding is effective in attenuating immune responses to prolonged continuous strenuous exercise, the same cannot be said for a soccer-specific intermittent exercise protocol. When overall exercise intensity is moderate, and changes in plasma glucose, cortisol and immune variables are relatively small, it would appear that carbohydrate ingestion has only a minimal influence on the immune response to exercise. 相似文献
