Effect of endurance training program based on anaerobic threshold (AT) for lower limb amputees.

We have already reported that the one-leg cycling test driven by the subject's sound leg as the exercise load test is effective in measuring the anaerobic threshold (AT) of unilateral lower limb amputees. The aim of this research is to investigate whether or not endurance training based on each subject's AT gained from the one-leg cycling test is useful in improving the physical fitness of lower limb amputees. The test subjects were all unilateral transfemoral amputees comprising a group of 14 undertaking endurance training and a control group of 10. The form of endurance training is driving an ergometer with the sound limb only in the same way as the load test. The training program was designed so that the subjects would exercise at a target heart rate corresponding to AT point for 30 minutes per day, 3-5 days each week for 6 weeks. After the training periods, in the training subjects the AT and maximum oxygen uptake (__O2max) increased significantly. The rate of increase averaged 36.5%, 26.0%, respectively, compared to their levels before the training. On the contrary, no changes occurred in the control subjects. These results suggest that our chosen training program based on each subject's AT is effective in improving the physical fitness of lower limb amputees.
