摘　　要：目的:研究制定适合疗养期间高性能战斗机飞行员进行专项下体负压和体能训练方案。方法:24名健康男性随机分为3组。体育锻炼组连续2周进行力量锻炼;下体负压锻炼组利用倾斜床进行下体负压锻炼。联合锻炼组每天以上述两种不同的锻炼方式进行复合锻炼。锻炼前后进行运动耐力及体能测试。结果:体育锻炼联合下体负压锻炼组锻炼10 d后PWC170/kg、最大耗氧量显著提高,肌肉爆发力及静肌力指标较锻炼前显著提高(P<0.05);单纯体育锻炼组平板卧推、负重蹲起、30 m冲刺跑、15 m蛙跳成绩较锻炼前显著提高(P<0.05),单纯下体负压组仅平板卧推及15 m蛙跳成绩较锻炼前显著提高(P<0.05)。结论:体育锻炼联合下体负压锻炼10 d后可明显提高受试者运动耐力及下肢、腰腹肌肉爆发力及静肌力。Objective ：To observe the effect of lower body negative pressure （LBNP） combinding with physical exercise on the exercise tolerance and physical ability. Methods： A total of 24 healthy male subjects were randomly divided into physical exercise group, LBNP group and combined group. The first group carried out muscular - based explosive exercise for two consecutive weeks. The second group exercised on a tilt bed -50 mmHg LBNP 10 rain every day. The third group eombinded with these two exercises. The physical working capacity （PWC） and muscular strength were tested before and after 10 -day＇s training. Results： After 10 -day＇s combinding exercise, the PWC170/kg, VO2max, bench- press, freeweight squat, and sit- up increased significantly, but the 30 m - running and 15 m -leapfrog decreased significantly （P 〈 0.05 ） ; After the physical exercise, the ability of bench - press, freeweight squat, 30 m -running and 15 m -leapfrog increased significantly （P 〈 0.05 ） ; After LBNP, only the ability of bench - press and 15m - leapfrog increased significantly （ P 〈 0.05 ）. Conclusion： LBNP combined with physical exercise could effectively increase the exercise capacity and muscular strength.
