The findings in ten subjects who had an amputation of the lower limb or limbs were studied before and after a fifteen-week aerobic conditioning program to determine if it improved cardiovascular fitness and reduced the effort of walking. Each subject exercised on an Air-Dyne ergometer (Schwinn, Chicago, Illinois) regularly during each week of the study period at 60 to 80 per cent of their estimated maximum heart rate. A test of maximum exercise on the ergometer and a test of walking on a treadmill were administered before and after training. After training, there was an increase of 25 per cent in the maximum capacity for exercise on the ergometer as well as significantly lower values for heart rate and consumption of oxygen during submaximum walking on the treadmill at various inclined grades. Aerobic conditioning was shown not only to improve cardiovascular fitness but also to increase the economy of walking in the subject who had an amputation of the lower limb or limbs.
对十名下肢截肢患者在为期十五周的有氧训练计划前后进行了研究，以确定该计划是否能改善心血管健康状况并减轻行走负担。在研究期间的每周，每位受试者都在空气阻力测力计（施温，伊利诺伊州芝加哥）上进行锻炼，运动强度为其预计最大心率的60%至80%。在训练前后分别进行了测力计最大运动测试和跑步机行走测试。训练后，测力计上的最大运动能力提高了25%，并且在跑步机上以不同倾斜度进行次最大强度行走时，心率和耗氧量的值也显著降低。结果表明，有氧训练不仅能改善心血管健康状况，还能提高下肢截肢患者的行走效率。
