Various combinations of training intensity, duration and frequency are often proposed to people with spinal cord injuries in order to improve their fitness. However, no consensus about a specific training program has been reached for such a population. Objective: This study investigated the effects of a short interval training program specifically designed for patients with spinal cord injuries. Methods: Paraplegic men performed 30-min wheelchair ergometry three times per week, for 4 weeks. Maximal dynamic performance and endurance capacity were studied before and after the training program with an incremental test (10 W/2 min) until volitional fatigue and a constant work rate test, respectively. Cardiorespiratory responses were continuously studied during each of these tests. Results: Training induced significant improvement in maximal tolerated power ( + 27.9%), and in peak oxygen consumption (O2, + 18.5%). After training the subjects were able to maintain the load applied during the constant test (total mechanical work + 210.7%), for a significantly longer time. The heart rate, O2 and ventilation values observed when the volunteers ended their first constant load test were significantly higher ( + 10%, + 10%, + 40% respectively) than those obtained after a similar time period during the second constant load test which was performed after the training program. Conclusion: After this short training period, with an appropriate combination of different types of training, duration, intensity and frequency exercises, we observed a significant improvement in the fitness level and endurance capacity of paraplegic subjects.
