为探索拳击运动员赛前训练期间机能变化规律,对我省优秀年轻运动员迎接全国比赛期间赛前训练的部分生化指标进行了监测.结果提示:赛前训练期拳击运动员的血色素(HB)和尿素氮(BUN)波动幅度不大(P＞0.05);血睾酮(T)在赛前训练中期出现下降(P＜0.05);血乳酸(BLA)在赛前训练中后期持续上升;肌酸激酶(CK)在赛前训练初期就出现较大幅度的变化(P＜0.01),中后期恢复正常.结论:不同的运动员在同一和/或不同一赛前训练期其机能变化规律各不相同,除HB外,其它指标均存在个体差异. 相似文献

对高水平散手运动员赛前训练部分生化指标的监测分析 总被引：8，自引：2，他引：6
通过文献资料法、实验法、数理统计法和系统方法,对湖北省参加2004年全国散打锦标赛的高水平运动员在赛前训练的部分生化指标进行了监测。结论表明:通过对赛前血色素、血尿素、血清肌酸激酶变化的观察,其能反映高水平运动员对赛前运动负荷的适应情况以及身体机能的状况。安静时血乳酸值对周训练后运动员机能水平变化的反映不灵敏,运动后血乳酸值可反映赛前训练对抗强度及运动员的无氧能力。 相似文献

散打运动员训练量监测与评定的生物学研究 总被引：5，自引：0，他引：5
采用实验测试的方法，研究男子散打运动员血尿素氮、血红蛋白、血睾酮、皮质醇、乳酸脱氢酶、肌酸激酶等生化指标的变化。认为大运动量训练后，散打运动员优秀组血尿素氮值明显低于一般组；散打运动员血清肌酸激酶的值明显变化，说明肌酸激酶是评价运动量的敏感指标；乳酸脱氢酶也是评价散打运动量的敏感指标；血睾酮变化不明显，说明血睾酮不是评价运动量的敏感指标。 相似文献

以中国国家女子马拉松队7名运动员为研究对象,对运动员在备战柏林世界锦标赛期间平原准备阶段、高原训练阶段和赛前平原准备阶段的血液指标(白细胞、血红蛋白、血清睾酮、肌酸激酶、血尿素)和机能指标(血压、晨脉)进行监控。总结在备战柏林世锦赛期间生理、生化指标的变化特点,探索适合我国女子马拉松运动员的训练模式。研究发现,高原训练期间要有节奏地安排训练负荷,不同训练负荷性质的内容要穿插进行,尤其是在高原训练的强化期,生理生化指标的变化较为明显,应当增加训练监控的密度,避免过度训练的发生;同时赛前高原训练阶段、赛前平原训练阶段大负荷强度的训练,必须建立在雄厚的有氧代谢能力基础上,否则运动员很难完成持续性的高强度的训练负荷。 相似文献

补充谷氨酰胺对大强度训练运动员血液生化指标和血浆谷氨酰胺水平的影响 总被引：6，自引：0，他引：6
目的 :探讨补充不同剂量的谷氨酰胺对运动员机体各血液生化指标和血浆谷氨酰胺水平的影响。方法 :12名运动员随机分成 4组 ,进行 2周大强度训练 ,训练期间分别补充不同剂量的谷氨酰胺 (0 .1g/kgbodywt/day ,0 .2 g/kgbodywt/day ,0 .3g/kgbodywt/day)和安慰剂。采集运动员训练周期开始前第 1天及最后 1天训练前后的血液 ,分别测定肌酸激酶 (CK)、乳酸脱氢酶 (LDH)、血尿素氮 (BUN)、血氨 (Ammonia)及血浆谷氨酰胺(Gln)的值。结果 :大强度训练会引起血液生化指标肌酸激酶、乳酸脱氢酶、血尿素氮、血氨的显著上升 (P <0 .0 5 ) ,补充谷氨酰胺并不改善上述指标的变化。大强度训练会导致血浆谷氨酰胺水平显著下降 (P <0 .0 5 ) ,补充中剂量 (0 .2 g/kgBW /day)谷氨酰胺能显著提高运动后血浆谷氨酰胺水平 (P <0 .0 5 )。 相似文献

Abstract The aim of this study was to quantify the physiological loads of programmed “pre-season” and “in-season” training in professional soccer players. Data for players during each period were included for analysis (pre-season, n = 12; in-season, n = 10). We monitored physiological loading of training by measuring heart rate and rating of perceived exertion (RPE). Training loads were calculated by multiplying RPE score by the duration of training sessions. Each session was sub-categorized as physical, technical/tactical, physical and technical/tactical training. Average physiological loads in pre-season (heart rate 124 ± 7 beats · min?1; training load 4343 ± 329 Borg scale · min) were higher compared with in-season (heart rate 112 ± 7 beats · min?1; training load 1703 ± 173 Borg scale · min) (P < 0.05) and there was a greater proportion of time spent in 80–100% maximum heart rate zones (18 ± 2 vs. 5 ± 2%; P < 0.05). Such differences appear attributable to the higher intensities in technical/tactical sessions during pre-season (pre-season: heart rate 137 ± 8 beats · min?1; training load 321 ± 23 Borg scale · min; in-season: heart rate 114 ± 9 beats · min?1; training load 174 ± 27 Borg scale · min; P < 0.05). These findings demonstrate that pre-season training is more intense than in-season training. Such data indicate that these adjustments in load are a direct attempt to deliver training to promote specific training adaptations. 相似文献

优秀赛艇运动员赛前生化指标的分析和评价 总被引：2，自引：0，他引：2
为探索浙江省赛艇运动员赛前训练期间身体机能变化的规律,以浙江赛艇队参加2009年第十一届全运会预选赛34名运动员为研究对象,通过赛前连续4周早晨安静时血红蛋白、血尿素2项指标测定及2次三级乳酸测试,达到赛前对运动员的身体机能和训练强度进行有效监控和调整的效果。结果表明：运动员的血尿素和血乳酸均有显著性变化,而血红蛋白未见显著性变化。所以,在赛艇训练中,应根据各项生化指标监控结果对运动员身体机能和训练强度进行调控,从而达到提高比赛成绩的目的。 相似文献

5周递增负荷训练对内分泌免疫机能影响的研究 总被引：1，自引：0，他引：1
目的：探讨递增负荷训练对机体内分泌免疫机能的影响。方法：实验对象进行为期5周的递增负荷训练，于集合训练开始前一天和第2周、第3周、第4周及第5周训练结束末36h后上午7：30-8：00取安静时肘静脉血，测定训练前及每一负荷训练阶段后外周血液中内分泌激素指标和免疫指标的变化。结果：T第3周比训练前显著升高（P〈0．05），C第3、第5周比训练前显著升高（P〈0．05），T／C比值第4周比训练前显著下降（P〈0．05）。CD4第2周比训练前显著下降（P〈0．05），而第3周比训练前显著升高（P〈0．05）；CDB第4周比训练前、第2周、第3周显著下降（P〈0．05），CD4／CDB比值第3、第4周均比训练前、第2周显著升高（P〈0．05）。结论：训练负荷是影响机体内分泌免疫机能的一个重要因素，中等负荷训练促进机体内分泌免疫机能，大负荷训练会降低机体的内分泌免疫机能，但随着对递增负荷应激的适应，机体的内分泌免疫机能又会得到加强。 相似文献

The purpose of this study was to develop statistical models that estimate the influence of training load on training injury and physical fitness in collision sport athletes. The incidence of training injuries was studied in 183 rugby league players over two competitive seasons. Participants were assessed for height, body mass, skinfold thickness, vertical jump, 10-m, 20-m and 40-m sprint time, agility, and estimated maximal aerobic power in the off-season, pre-season, mid-season, and end-season. Training load and injury data were summarised into pre-season, early-competition, and late-competition training phases. Individual training load, fitness, and injury data were modelled using a logistic regression model with a binomial distribution and logit link function, while team training load and injury data were modelled using a linear regression model. While physical fitness improved with training, there was no association (P=0.16-0.99) between training load and changes in physical fitness during any of the training phases. However, increases in training load during the early-competition training phase decreased (P= 0.04) agility performance. A relationship (P= 0.01-0.04) was observed between the log of training load and odds of injury during each training phase, resulting in a 1.50 - 2.85 increase in the odds of injury for each arbitrary unit increase in training load. Furthermore, during the pre-season training phase there was a relationship (P= 0.01) between training load and injury incidence within the training load range of 155 and 590 arbitrary units. During the early and late-competition training phases, increases in training load of 175-620 arbitrary units and 145-410 arbitrary units, respectively, resulted in no further increase in injury incidence. These findings demonstrate that increases in training load, particularly during the pre-season training phase, increase the odds of injury in collision sport athletes. However, while increases in training load from 175 to 620 arbitrary units during the early-competition training phase result in no further increase in injury incidence, marked reductions in agility performances can occur. These findings suggest that reductions in training load during the early-competition training phase can reduce the odds of injury without compromising agility performances in collision sport athletes. 相似文献

不同负荷运动训练对大鼠红细胞膜特性的影响 总被引：6，自引：0，他引：6
通过实验研究得出以下结论:(1)一次急性运动可造成红细胞的破坏增多,但小负荷的运动训练可以通过增强机体的抗氧化能力,改善红细胞膜性能等途径,最终增加动物血液中红细胞的数量,使其有氧代谢能力及抵抗力竭运动造成的能力均提高。大负荷的训练结果不但使红细胞的破坏增加,且单个红细胞的机能也明显下降,在训练结束后可能发生运动性贫血。(2)大负荷训练后RBCM流动性下降,与其丙二醛(MDA)含量及抗氧化酶SOD活性的变化高度相关。 相似文献
