【摘要】：目的：通過對運動前后和運動后不同方法恢復(fù)前后膝關(guān)節(jié)本體感覺及其相關(guān)指標(biāo)變化的分析，研究單側(cè)肢體膝關(guān)節(jié)離心-向心運動對雙側(cè)肢體膝關(guān)節(jié)本體感覺的影響，以及運動后不同方式恢復(fù)對膝關(guān)節(jié)本體感覺的變化影響。 方法：將32名健康男性隨機分為：對照組（自然恢復(fù)組，N=8）和積極恢復(fù)組，后者分為拉伸組（拉伸恢復(fù)20min，N=8）、加壓組（間歇加壓恢復(fù)20min，N=8）、拉伸+加壓組（拉伸10min+間歇加壓10min，N=8）。各組按運動方案完成單側(cè)肢體膝關(guān)節(jié)離心-向心運動（角速度60°/s，20次×5組，組間休息2min），后各組采用不同恢復(fù)方法進行恢復(fù)。分別于運動前、運動后即刻和恢復(fù)后即刻，運用美國Boidex System-3等速測試系統(tǒng)對雙側(cè)肢體進行本體感覺指標(biāo)（主動位置覺、被動位置覺、肌肉力覺、關(guān)節(jié)反應(yīng)角度）和最大等長肌肉收縮力量（MVIC）的測試，同時進行血乳酸濃度測定、肌肉酸痛程度評分。運用Microsoft excel2007、SPSS17.0統(tǒng)計軟件對測試數(shù)據(jù)進行統(tǒng)計、整理、分析。 結(jié)果：（1）單側(cè)肢體離心-向心運動后，，各實驗組運動后即刻血乳酸濃度及運動后即刻肌肉酸痛程度評分與運動前相比顯著升高（P0.01）；進行不同方法恢復(fù)后即刻各實驗組兩指標(biāo)均顯著高于運動前（P0.01），但3組積極性恢復(fù)組顯著低于對照組（P0.05），且3組積極性恢復(fù)組之間無差異（P0.05）。 （2）單側(cè)肢體離心-向心運動后即刻，各實驗組運動側(cè)肢體MVIC顯著低于運動前（P0.01），本體感覺指標(biāo)值均顯著大于運動前（P0.01）；經(jīng)過不同方法恢復(fù)后，3組積極性恢復(fù)組運動側(cè)肢體MVIC及本體感覺指標(biāo)值有所恢復(fù)，與運動前相比均無差異（p0.05），且各積極性恢復(fù)組之間沒有差異（p0.05）。但對照組MVIC仍顯著低于運動前（p0.05），本體感覺指標(biāo)值均大于運動前（p0.05），（大于3組積極性恢復(fù)組）且與各積極性恢復(fù)組相比均有差異（p0.05）。 （3）單側(cè)肢體離心-向心運動后即刻，各實驗組非運動側(cè)肢體MVIC顯著低于運動前（P0.05），本體感覺各指標(biāo)值顯著大于運動前（P0.05）；經(jīng)過不同方法恢復(fù)后，各組非運動側(cè)肢體的MVIC及本體感覺指標(biāo)值與運動前相比無差異（p0.05），且各組間比較無差異（p0.05）。 （4）運動側(cè)肢體離心-向心運動前，各實驗組MVIC及本體感覺指標(biāo)值與非運動側(cè)比較均無差異（p0.05）；各實驗組運動后即刻及恢復(fù)后即刻，對照組運動側(cè)MVIC顯著低于非運動側(cè)（P0.05），運動側(cè)本體感覺指標(biāo)值顯著大于非運動側(cè)（P0.05）；恢復(fù)后3組積極性恢復(fù)組各指標(biāo)值運動側(cè)與非運動側(cè)相比均無差異（p0.05）。 結(jié)論：（1）單側(cè)肢體離心-向心運動可使血乳酸濃度升高，運動側(cè)肢體出現(xiàn)肌肉酸痛、MVIC下降、膝關(guān)節(jié)本體感覺功能明顯下降。 （2）單側(cè)肢體離心-向心運動可影響非運動側(cè)肢體，使非運動側(cè)肢體MVIC下降、膝關(guān)節(jié)本體感覺功能明顯下降。但影響程度小于運動側(cè)。 （3）單側(cè)肢體離心-向心運動后，雙側(cè)肢體均出現(xiàn)“過度伸”、“過度屈”的現(xiàn)象；肌肉力覺出現(xiàn)“估計過高”的現(xiàn)象。 （4）拉伸法、間歇加壓法及拉伸+間歇加壓法等恢復(fù)方法比較自然恢復(fù)法，均能有效加速乳酸清除，減緩肌肉酸痛發(fā)展，加快MVIC恢復(fù)，從而有效促進膝關(guān)節(jié)本體感覺的恢復(fù)。這3種方法對本體感覺恢復(fù)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.
