【摘要】：目的：通过对运动前后和运动后不同方法恢复前后膝关节本体感觉及其相关指标变化的分析，研究单侧肢体膝关节离心-向心运动对双侧肢体膝关节本体感觉的影响，以及运动后不同方式恢复对膝关节本体感觉的变化影响。方法：将32名健康男性随机分为：对照组（自然恢复组，N=8）和积极恢复组，后者分为拉伸组（拉伸恢复20min，N=8）、加压组（间歇加压恢复20min，N=8）、拉伸+加压组（拉伸10min+间歇加压10min，N=8）。各组按运动方案完成单侧肢体膝关节离心-向心运动（角速度60°/s，20次×5组，组间休息2min），后各组采用不同恢复方法进行恢复。分别于运动前、运动后即刻和恢复后即刻，运用美国Boidex System-3等速测试系统对双侧肢体进行本体感觉指标（主动位置觉、被动位置觉、肌肉力觉、关节反应角度）和最大等长肌肉收缩力量（MVIC）的测试，同时进行血乳酸浓度测定、肌肉酸痛程度评分。运用Microsoft excel2007、SPSS17.0统计软件对测试数据进行统计、整理、分析。结果：（1）单侧肢体离心-向心运动后，，各实验组运动后即刻血乳酸浓度及运动后即刻肌肉酸痛程度评分与运动前相比显著升高（P0.01）；进行不同方法恢复后即刻各实验组两指标均显著高于运动前（P0.01），但3组积极性恢复组显著低于对照组（P0.05），且3组积极性恢复组之间无差异（P0.05）。（2）单侧肢体离心-向心运动后即刻，各实验组运动侧肢体MVIC显著低于运动前（P0.01），本体感觉指标值均显著大于运动前（P0.01）；经过不同方法恢复后，3组积极性恢复组运动侧肢体MVIC及本体感觉指标值有所恢复，与运动前相比均无差异（p0.05），且各积极性恢复组之间没有差异（p0.05）。但对照组MVIC仍显著低于运动前（p0.05），本体感觉指标值均大于运动前（p0.05），（大于3组积极性恢复组）且与各积极性恢复组相比均有差异（p0.05）。（3）单侧肢体离心-向心运动后即刻，各实验组非运动侧肢体MVIC显著低于运动前（P0.05），本体感觉各指标值显著大于运动前（P0.05）；经过不同方法恢复后，各组非运动侧肢体的MVIC及本体感觉指标值与运动前相比无差异（p0.05），且各组间比较无差异（p0.05）。（4）运动侧肢体离心-向心运动前，各实验组MVIC及本体感觉指标值与非运动侧比较均无差异（p0.05）；各实验组运动后即刻及恢复后即刻，对照组运动侧MVIC显著低于非运动侧（P0.05），运动侧本体感觉指标值显著大于非运动侧（P0.05）；恢复后3组积极性恢复组各指标值运动侧与非运动侧相比均无差异（p0.05）。结论：（1）单侧肢体离心-向心运动可使血乳酸浓度升高，运动侧肢体出现肌肉酸痛、MVIC下降、膝关节本体感觉功能明显下降。（2）单侧肢体离心-向心运动可影响非运动侧肢体，使非运动侧肢体MVIC下降、膝关节本体感觉功能明显下降。但影响程度小于运动侧。（3）单侧肢体离心-向心运动后，双侧肢体均出现“过度伸”、“过度屈”的现象；肌肉力觉出现“估计过高”的现象。（4）拉伸法、间歇加压法及拉伸+间歇加压法等恢复方法比较自然恢复法，均能有效加速乳酸清除，减缓肌肉酸痛发展，加快MVIC恢复，从而有效促进膝关节本体感觉的恢复。这3种方法对本体感觉恢复具有相同水平的效果。
[Abstract]:Objective: To study the influence of the centrifugal centripetal movement of the knee joint on the proprioception of the knee joints of the bilateral limbs, and the effect of different ways of restoring the proprioception of the knee joint after exercise.
Methods: 32 healthy men were randomly divided into two groups: control group (natural recovery group, N=8) and active recovery group. The latter was divided into stretching group (tensile recovery 20min, N=8), compression group (intermittent pressurization to restore 20min, N=8), tensile + compression group (10min+ intermittent compression 10min, N=8). The centrifugal centripetal movement of knee joint of unilateral limbs was completed according to exercise scheme. The angular velocity was 60 /s, 20 times * 5, and the group rest 2min). The groups were recovered by different recovery methods. Before exercise, immediately after exercise and immediately after recovery, the United States Boidex System-3 isokinetic test system was used to carry out the proprioception index (active position sense, passive position sense, muscle force sense, joint reaction angle) with the American System-3 isokinetic test system. The test of the maximum muscle contraction force (MVIC), measurement of blood lactic acid concentration and the degree of muscle pain, and using Microsoft Excel2007, SPSS17.0 statistics software to make statistics, sorting and analysis of the test data.
Results: (1) after the unilateral limb centrifugation and centripetal movement, the levels of immediate blood lactate and immediate muscle pain after exercise were significantly higher after exercise than before exercise (P0.01). The two indexes of all the experimental groups were significantly higher than those before the exercise (P0.01), but the 3 groups of active recovery groups were significantly lower than those in the 3 groups. According to group P0.05, there was no difference between the 3 groups (P0.05).
(2) immediately after the unilateral limb centrifugation - centripetal movement, the MVIC of the motor side limbs of the experimental groups was significantly lower than that before the exercise (P0.01), and the value of the proprioception index was significantly greater than that before the exercise (P0.01). After the recovery, the MVIC and proprioception indexes of the motor side limbs of the 3 groups were recovered, and there was no difference compared with those before the exercise (p0. 05) and there was no difference between the groups of positive recovery (P0.05), but the MVIC of the control group was still significantly lower than that before the exercise (P0.05), and the value of the proprioception index was higher than that before the exercise (P0.05), (more than 3 groups of positive recovery groups), and compared with the positive recovery group (P0.05).
(3) immediately after the unilateral limb centrifugation - centripetal movement, the MVIC of the non motor side limbs of the experimental groups was significantly lower than that before the exercise (P0.05), and the values of the proprioception were significantly greater than that before the exercise (P0.05). After the recovery, the values of MVIC and proprioception of the non motor side limbs were not different from those before the exercise (P0.05), and the comparison between each group was compared with those before the exercise (P0.05). There is no difference (P0.05).
(4) before movement side limb centrifugation and centripetal movement, there was no difference in MVIC and proprioception between the experimental group and the non motor side (P0.05). The MVIC of the control group was significantly lower than that of the non motor side (P0.05), and the sensory index of the motor side was significantly greater than that of the non motor side (P0.05) in the control group, and 3 after the recovery. There was no difference in the index values of the active recovery group between the motor side and the non motor side (P0.05).
Conclusions: (1) the concentration of blood lactic acid in the unilateral extremities can increase the concentration of blood lactic acid, the muscle ache of the motor side limbs, the MVIC decrease, and the function of the proprioception of the knee joint decrease obviously.
(2) unilateral limb centrifugation and centripetal movement can affect the non motor side limbs, make the MVIC of the non motor side decrease and the proprioceptive function of the knee joint decrease obviously, but the degree of influence is less than that of the motor side.
(3) after unilateral limb centrifugation and centripetal movement, both sides showed "over stretched" and "excessive flexion" phenomenon.
(4) tensile method, intermittent compression method and tensile + intermittent pressurization method are used to compare the natural recovery method, which can effectively accelerate the clearance of lactic acid, slow down the development of muscle ache and accelerate the recovery of MVIC, thus effectively promote the recovery of the proprioception of the knee joint. These 3 methods have the same effect on the recovery of the proprioception.
