有氧功率自行车训练对偏瘫患者和健康人心血管反应的影响分析

Impact Analysis of Aerobic Power Cycling Training on Cardiovascular Responses of Patients With Hemiplegia and Healthy Individuals

目的对比分析偏瘫患者与健康人行有氧功率自行车训练时心血管系统的反应。方法选择2015年1—6月在南京大学医学院附属鼓楼医院进行康复治疗的16例脑卒中偏瘫患者(试验组)和16例志愿者(对照组),在相同负荷运动强度40 W下,进行15 min的自行车训练后,测量对照组和试验组训练前后的心率、血压,评估主观疲劳程度(RPE)。结果试验组训练后心率增幅和运动后RPE分值较对照组增加,差异均有统计学意义(t=8.776、14.269,P<0.01)。对照组训练前后的收缩压、舒张压及脉压比较,差异无统计学意义(P>0.01);试验组训练前后收缩压和舒张压比较,差异有统计学意义(P<0.01),脉压间差异无统计学意义(P>0.01)。结论在相同负荷运动强度下,偏瘫患者训练后心率及收缩压、舒张压较健康人增幅加大,提示治疗师在给偏瘫患者制定运动处方时要考虑到患者的运动强度。

Objective To make a comparative analysis of cardiovascular responses in patients with hemiplegia and healthy individuals when doing aerobic power bicycle training. Methods 16 cases with stroke and hemiplegia（ experimental group）and 16 cases of volunteers（ control group）were selected after rehabilitation in Nanjing Drum Tower Hospital,the Affiliated Hospital of Nanjing University Medical School from January to June 2015. Under the same load exercise intensity of 40 W,they took 15 min of bicycle training. The heart rate,blood pressure and rating of perceived exertion（RPE）were measured before and after training in control group and experimental group. Results In the experimental group,the increase of heart rate and RPE after exercise increased more greatly than those in the control group（t = 8. 776,14. 269,P ﹤ 0. 01）. There was no significant difference in SBP,DBP and PP of control group before and after training（ P ﹥ 0. 01）;There were significant differences in SBP and DBP of experimental group before and after training（P ﹤ 0. 01）,but there was no significant difference in PP（ P ﹥ 0. 01）. Conclusion Under the same exercise intensity,the heart rate,SBP and DBP of the patients with hemiplegia after training increase more greatly than those of the healthy individuals,suggesting that the therapist should take the exercise intensity of the patients with hemiplegia into account.
