【摘要】 目的 疗养期间飞行员进行矿泉游泳和矿泉浴,观察心脏泵血、收缩功能的变化。方法 15名现役飞行员随机分为3组,对照组完成正常疗养科目,矿泉游泳组和矿泉浴组在完成正常疗养科目的同时,矿泉游泳组每天进行矿泉游泳锻炼;矿泉浴组每天进行全身矿泉浴,2周后利用心电机械图法和阻抗法测量锻炼前后心脏的收缩功能与泵血功能。结果 锻炼后,矿泉游泳组每搏量(SV)、心输出量(CO)、心指数(CI)有升高趋势;总外周阻力(TPR)有降低趋势;同时左室射血时间(LVET)、等容收缩时间(ICT)、等容收缩时间与左室射血时间比值(ICT/LVET)及射血分数(EF)有升高趋势;射血前期(PEP)和射血前期与左室射血时间比值(PEP/LVET)有降低趋势。矿泉浴组中ICT、ICT/LVET显著提高,差异有统计学意义(P<0.05)。结论 自然疗养因子矿泉游泳对心功能有一定的影响。

【Abstract】 Objective To observe the change of left ventricular pump and contract function in pilots after swimming and hot spring training.Methods Fifteen healthy male pilots were randomly divided into three groups:control group,mineral spring swimming group and mineral bath group.The control group was received routine recuperation,the mineral spring swimming group was received swimming training and the mineral bath group was received mineral bath.After two weeks training,the left ventricular pump and contract function were measured by machcardiogram and impedance method.Results After training in the mineral spring swimming group,the stroke volume(SV),cardiac output(CO)and cardiac index(CI)had a tendency to increase,while total peripheral resistance(TPR)had a tendency to decrease;Left ventricular ejection time(LVET),isovolumetric contraction time(ICT),isovolumetric contraction time/left ventricular ejection time(ICT/LVET)and ejection fraction(EF)tended to be increased,pre-ejection period(PEP)and pre-ejection period/left ventricular ejection time(PEP/LVET)tended to be decreased.In the mineral bath group,ICT and ICT/LVET were increased significantly(P<0.05).Conclusion Natural convalescent factors of mineral spring have certainly effect on cardiac function of pilots.

随着战斗机性能的提高及飞行任务的加重,增加了飞行人员的生理与心理负荷,容易产生心血管功能障碍、飞行疲劳、慢性失眠和颈腰椎疾病等。疗养是利用各种自然疗养因子和人工疗养因子,对处于疾病或“亚健康”状态下的人员进行综合治疗,达到预防疾病和恢复健康的目的[1]。如何更有效地在疗养期间使飞行员得到充分的休养恢复成为一项紧迫的课题。本课题就是在飞行员疗养期间,通过观察其心脏泵血和收缩功能指标的变化,研究自然疗养因子矿泉浴与矿泉游泳对飞行人员心功能的影响,探讨自然疗养因子的应用对提高疗养效果的作用。
