A study was conducted to investigate the efficacy of aerobic exercise for weight loss and fat reduction using an arm crack ergometer in a wheelchair-dependent patient with distal-type progressive muscular dystrophy. The subject was instructed to perform arm cracking 2 days per week for 6 months with a work rate of 29 W for 20 min in the initial stage, and 38 W for 30 min in the terminal stage of training. Body weight, skinfold thickness, and blood pressure were measured throughout the training period, and heart rate was monitored during every session. Also, lipid profiles and levels of some enzymes(γ-GTP, GOT, GPT and CPK) were examined at the 4th month of training, and compared with data obtained before training. Heart rate was not increased despite the increase in work rate, and was controlled between 110 and 120 beats/min over the training period. Body weight decreased by 3 kg with a decrease in the sum of two skinfold thickness after the training. Furthermore, a decline in blood pressure of approximately 10% was shown at the end of training, and the levels of triglycerides, γ-GTP, and GPT were improved. It is possible that arm cranking exercise in wheelchair-dependent patients with progressive muscular dystrophy is effective not only for fat reduction but also for improvement of cardio-respiratory function.
