摘要
目的:探讨站姿振动力量训练和传统力量训练后,血液流变性的变化特征和生理学机制。方法:运动训练专业21名志愿者,在站姿振动或传统训练条件下,负重深蹲训练12周,测试血液流变性4次。结果:实验组的全血低切粘度、血沉K值和红细胞压积明显增高,电泳时间明显延长;高频低振幅组的全血高切粘度、全血相对粘度和全血高切还原粘度也明显增高,均与对照组差异显著。结论:站姿振动使血液流变性降低,流阻增大,红细胞数量增加,变形能力降低,其中高频低振幅振动的影响更早、更明显。
Objective： To investigate the changes of blood rheology indexes and physiological mechanism after the standing vibration strength training and traditional strength training. Methods： Squat training with heavy was carried out in 21 volunteers of sports training specialty, in the condition of traditional or standing vibration for 12 weeks and with 4 blood rheology tests. Results： The whole blood relative viscosity at low shear, the K value of erythrocyte sedi- mentation rate and hematocrit of the experimental groups were significantly higher. Erythrocyte electrophoresis time prolonged obviously, the whole blood viscosity, blood relative viscosity and reduction viscosity of blood of high frequency and low amplitude group was significantly increased significantly, compared with control group. Conclusions： Standing vibration leads to the reduction of blood rheology and increases the peripheral resistance and the num- ber of red blood cells, decreases of plasma deformability, the effects of high frequency and low amplitude vibration appears earlier and more obviously. We should scientifically design the vibration training parameters and improve the ability of medical supervision.
