【摘要】：目的:由于现代五项是由不同项群的子项目构成的组合型项目,且各子项的训练内容和特征不尽相同,五个项目既是有区别的五个子项目但又是一个整体,因此优秀现代五项运动员通常都采用板块训练模式。怎样判断现代五项运动员不同训练板块的运动训练强度和运动训练后身体机能状态对于运动实践极为重要,因此本研究旨在通过近红外光谱(NIRS)测试不同训练板块下运动员的肌肉氧代谢参数,探讨其是否可以作为评价优秀现代五项运动员运动训练强度和训练量符合参数的可行性。方法:通过NIRS采用动脉闭塞法测试优秀现代五项女子运动员在不同训练负荷(高、低强度负荷)以及不同训练状态(疲劳前后、恢复前后)下骨骼肌肌肉耗氧量、肌肉氧饱和度半恢复时间、全恢复时间、超量恢复状态以及超量恢复复原时间来评价优秀现代五项女子运动员疲劳状态下肌肉氧代谢特征,不同训练负荷强度对优秀现代五项女子运动员肌肉氧代谢能力的影响以及不同训练负荷强度对优秀现代五项女子运动员疲劳恢复的影响。结果:1、优秀现代五项女子运动员在运动训练后的肌肉耗氧量由3.3±0.4(μm)显著下降至2.4±0.4(μm)(P0.05);肌氧饱和度半恢时间由4.3±1.2(s)显著延长为5.2±1.0(s)(P0.01);肌氧饱和度全恢复时间由15.4±3.2(s)显著延长为17.5±4.1(s)(P0.01)。2、与低强度运动负荷相比较优秀现代五项女子运动员在高强度负荷训练前后肌肉耗氧量为0.8±0.5(μm)显著下降至0.4±0.3(μm)(P0.05);肌肌氧饱和度半恢复时间的△值由2.7±0.8(s)显著下降至1.8±0.5(s)(P0.05);肌氧饱和度全恢复时间△值的由6.1±1.4(s)显著延长为1.5±0.2(s)(P0.01)。3、与低强度运动负荷相比较优秀现代五项女子运动员高强度负荷疲劳恢复前后肌氧饱和度全恢复时间的△值由7.8±2.1(s)极显著下降为1.9±0.5(s)(P0.01);肌氧饱和度超量恢复以及肌氧饱和度超量恢复复原时间均无统计学意义。结论:1、优秀现代五项女子运动员训练后骨骼肌表现为肌肉耗氧量下降、肌肉氧饱的度半恢复时间和肌肉氧饱和度全恢复时间延长。2、肌肉耗氧量△值、肌氧饱和度半恢复时间和肌氧饱和度全恢复时间的△值与训练强度大小相关,可以作为评价优秀现代五项运动员运动训练后疲劳状态的参数。3、肌氧变化的全恢复时间△值与训练强度大小有关,肌氧变化的全恢复时间△值可以作为评价运动训练后恢复参数。
[Abstract]:Objective: because modern pentathlon is composed of subitems of different project groups, and the training contents and characteristics of each subitem are different, the five items are not only five sub-items but also a whole. Therefore, the excellent modern pentathlon athletes usually adopt the plate training mode. How to judge the training intensity and the physical function state of different training plates of modern pentathlon athletes is very important for sports practice. Therefore, the purpose of this study is to measure the oxygen metabolism parameters of the muscles of athletes under different training plates by NIR spectroscopy (NIR). To explore whether it can be used to evaluate the training intensity and training quantity of elite modern pentathlon athletes in accordance with the parameters. NIRS was used to measure the different training loads of elite modern pentathlon women athletes by arterial occlusion (. High. Low intensity load) and different training state (before and after fatigue, before and after recovery) skeletal muscle muscle oxygen consumption, muscle oxygen saturation half recovery time, full recovery time. To evaluate the characteristics of muscle oxygen metabolism in fatigue state of elite modern pentathlon women athletes. Effects of different training load intensity on muscle oxygen metabolism ability of elite modern pentathlon female athletes and effects of different training load intensity on fatigue recovery of elite modern pentathlon female athletes. Results: 1. The muscle oxygen consumption of elite modern pentathlon women athletes decreased from 3.3 卤0.4 (渭 m) to 2.4 卤0.4 (渭 m) after training. The hemi-restoration time of muscle oxygen saturation was significantly prolonged from 4.3 卤1.2 s to 5.2 卤1.0 m ~ (-1) (P ~ (0.01)). The total recovery time of muscle oxygen saturation was significantly prolonged from 15.4 卤3.2g / s to 17.5 卤4.1 / kg / kg / kg. Compared with the low intensity exercise load, the muscle oxygen consumption of the elite modern pentathlon female athletes decreased significantly from 0.8 卤0.5 (渭 m) to 0.4 卤0.3 (渭 m) before and after the high-intensity load training. P0.05; The half recovery time of muscle oxygen saturation decreased significantly from 2.7 卤0.8 s to 1.8 卤0.5 渭 s (P 0.05). The time of full recovery of muscle oxygen saturation was significantly prolonged from 6.1 卤1.4 s to 1.5 卤0.2 P 0.01 ~ (th). Compared with low intensity exercise load, the total recovery time of muscle oxygen saturation of modern pentathlon female athletes before and after recovery of high intensity load fatigue is 7.8 卤2.1 s). Very significantly decreased to 1. 9 卤0. 5% P0. 01% (P < 0. 01). There was no significant difference in the recovery time of muscle oxygen saturation and the recovery time of muscle oxygen saturation. Conclusion the skeletal muscle of elite modern pentathlon women athletes showed a decrease in muscle oxygen consumption after training. The partial recovery time of muscle oxygen saturation and the total recovery time of muscle oxygen saturation were prolonged by 0.2, and the value of muscle oxygen consumption, muscle oxygen saturation half recovery time and muscle oxygen saturation full recovery time were related to the training intensity. It can be used as a parameter of evaluating the fatigue state of elite modern pentathlon athletes after training. The total recovery time value of muscle oxygen change is related to the training intensity. The total recovery time of muscle oxygen change can be used as a parameter to evaluate the recovery after exercise training.
