We investigated the effects of combined lower body (LB) endurance and upper body (UB) resistance training on endurance, strength, blood lipid profile and body composition in active older men. Ten healthy still active men (73+/-4 years, V(O2) peak: 36 (31-41) ml min-1 kg-1) were tested before and after 14 weeks of combined training (3 times week-1). Training consisted of 3x12 min of high intensity interval training on a bicycle for endurance interspersed by 3x12 min of UB resistance exercises. V(O2) peak during leg cycling and arm cranking, isokinetic torque of knee extensor and shoulder abductor and the cross-sectional area (CSA) of several muscles from UB and LB were measured. Sagittal abdominal diameter (SAD) and abdominal fat area were measured on MRI scans. Total body composition was assessed by hydrostatic weighing (HW) and dual-energy X-ray absorptiometry (DEXA). Blood lipid profile was assessed before and after training. By the end of the training period, V(O2) peak (l min-1) increased significantly by 9 and 16% in leg cycling and arm cranking tests, respectively. Maximal isokinetic torque increased both for the knee extensor and shoulder abductor muscle groups. CSA increased significantly in deltoid muscle. Percentage of body fat decreased by 1.3% (P<0.05) and abdominal fat and SAD decreased by 12 and 6%, respectively (P<0.01). There was also a significant decrease in total cholesterol and low-density lipoprotein. Thus, combined LB endurance and UB resistance training can improve endurance, strength, body composition and blood lipid profile even in healthy active elderly.
我们研究了下身（LB）耐力与上身（UB）阻力联合训练对活跃老年男性的耐力、力量、血脂谱和身体成分的影响。10名健康且仍活跃的男性（73±4岁，峰值摄氧量：36（31 - 41）ml·min⁻¹·kg⁻¹）在进行14周联合训练（每周3次）前后接受了测试。训练包括在自行车上进行3组、每组12分钟的高强度间歇训练以提高耐力，期间穿插3组、每组12分钟的上身阻力练习。测量了腿部骑行和手臂曲柄运动时的峰值摄氧量、膝关节伸肌和肩关节外展肌的等速扭矩以及上身和下身几块肌肉的横截面积（CSA）。通过磁共振成像扫描测量矢状位腹径（SAD）和腹部脂肪面积。通过水下称重（HW）和双能X线吸收法（DEXA）评估全身成分。在训练前后评估血脂谱。到训练期结束时，腿部骑行和手臂曲柄运动测试中的峰值摄氧量（l·min⁻¹）分别显著增加了9%和16%。膝关节伸肌和肩关节外展肌组的最大等速扭矩均增加。三角肌的CSA显著增加。体脂百分比下降了1.3%（P<0.05），腹部脂肪和SAD分别下降了12%和6%（P<0.01）。总胆固醇和低密度脂蛋白也显著下降。因此，即使对于健康活跃的老年人，下身耐力与上身阻力联合训练也可以改善耐力、力量、身体成分和血脂谱。
