【摘要】：1目的為了進一步探索高原訓(xùn)練對女子賽艇運動員身體機能和運動能力的影響,發(fā)現(xiàn)其高原訓(xùn)練前后有關(guān)生理生化指標(biāo)的變化規(guī)律,為科學(xué)指導(dǎo)賽艇運動項目的訓(xùn)練提供更多的科學(xué)依據(jù)。2方法以備戰(zhàn)2017年全運會的9名天津女子公開級賽艇運動員為研究對象,對其在高原訓(xùn)練前、后和訓(xùn)練期間相關(guān)生理生化指標(biāo)進行監(jiān)測,分析高原訓(xùn)練對女子賽艇運動員身體機能的影響和變化規(guī)律,并對其階段測試的結(jié)果進行評定。3結(jié)果3.1與高原前準(zhǔn)備階段相比,高原訓(xùn)練第6周RBC、HCT、Hb含量和WBC明顯升高,血糖則顯著下降(p0.05),其它指標(biāo)無明顯變化。3.2與上高原前相比,高原訓(xùn)練后三級負(fù)荷測試和2000m測試中乳酸均明顯下降(p0.01),2000m測試血乳酸恢復(fù)速率明顯加快(p0.01)。但2000m測試中平均功率下降,測試成績降低。3.3高原訓(xùn)練后,4mmol/L和2mmol/L乳酸功率明顯上升(p0.05),心率顯著下降(p0.05)。4結(jié)論4.1高原訓(xùn)練能夠明顯增加女子賽艇運動員的RBC、HCT、Hb含量和WBC數(shù)量,說明高原訓(xùn)練能夠增強機體運輸氧氣的能力和免疫功能。4.2高原訓(xùn)練和高原后調(diào)適階段,運動員血糖明顯降低,表明訓(xùn)練期間機體糖代謝供能增加,提示訓(xùn)練中應(yīng)注意補糖。4.3高原訓(xùn)練期間,女子賽艇運動員的身體機能相關(guān)指標(biāo)均在正常范圍內(nèi)波動,但在高原訓(xùn)練第4周紅細(xì)胞系和白細(xì)胞系指標(biāo)均出現(xiàn)下降,表明經(jīng)過3周大強度訓(xùn)練后,運動員可能出現(xiàn)機體疲勞,免疫機能受到抑制。4.4高原訓(xùn)練后第1周,運動員體能下降,2000m測試成績降低。高原后調(diào)適階段,運動員血乳酸閾功率上升,心率下降;三級負(fù)荷測試過程中的乳酸明顯下降,2000m測試過程中的乳酸恢復(fù)速率明顯加快,運動員有氧能力得到有效提升。
[Abstract]:Objective to explore the effect of altitude training on the physical function and sports ability of female rowers, and to find out the changes of physiological and biochemical indexes before and after plateau training. To provide more scientific basis for scientific training of rowing events. (2) taking 9 Tianjin women open level rowers in preparation for the 2017 National Games as research objects, before training on the plateau, The physiological and biochemical indexes were monitored after and during training, and the influence and variation of altitude training on the body function of female rowers were analyzed. Results 3.1 compared with preplateau preparation stage, RBC,HCT,Hb content and WBC increased significantly in the 6th week of high altitude training, but blood glucose decreased significantly (p0.05). There was no significant change in other indexes. 3.2 compared with before altitude training, the lactic acid decreased significantly in the third stage load test and 2000m test after high altitude training (p0.01), and the recovery rate of blood lactic acid in 2000m test significantly accelerated (p0.01). However, the average power of 2000m test decreased and the test result decreased. 3.3 after high altitude training, the lactic acid power of 4mmol/L and 2mmol/L increased significantly (p0.05). Conclusion\ The results showed that high altitude training could enhance the ability of transporting oxygen and immune function. 4.2 during altitude training and post-altitude adjustment, the blood glucose of athletes decreased significantly, which indicated that the energy supply of glucose metabolism increased during the training period. It was suggested that attention should be paid to the supplement of sugar. 4.3 during plateau training, the relative indexes of body function of female rowers fluctuated within the normal range, but at the 4th week of high altitude training, the indexes of erythrocyte system and white blood cell system both decreased. The results showed that after 3 weeks of intensive training, the athletes might appear fatigue, and their immune function would be inhibited. In the first week of 4.4 plateau training, the physical ability of the athletes decreased, and the result of 2000m test decreased. During the adjustment period after plateau, the blood lactate threshold power increased, the heart rate decreased, the lactate recovery rate increased obviously during the third stage load test, and the aerobic capacity of the athletes was improved effectively.
