“…1 h at a moderate intensity is recommendable. 4 The measured mechanical efficiency shows values comparable to the findings of Hopman et al (1995) 3 in a laboratory setting. The higher mechanical efficiency in handbiking as compared to that in the race wheelchair shows the importance and benefits for wheelchair-dependent persons using a handbike in sport-specific circumstances but especially in all-day mobility.…”

“…The higher mechanical efficiency in handbiking as compared to that in the race wheelchair shows the importance and benefits for wheelchair-dependent persons using a handbike in sport-specific circumstances but especially in all-day mobility. 3,4,11 The measured temperature values with a maximum of 40.41C were remarkably high at the end of the marathon. As the athlete is not able to sweat below the lesion level due to his paraplegia, disturbances of his thermoregulation with the risk of hyperthermia had to be seriously considered.…”

“…9 In handbiking, the extent of energy consumption, which is a very important factor from the point of view of preventive medicine, is highly encouraging. 4,11,12 The American College of Sports Medicine (ACSM), for example, recommends an additional energy consumption by endurance sport on 3 days/week with a moderate intensity to prevent arteriosclerotic diseases. 13 According to the examinations by Paffenbarger et al (1986) 14 a clearly higher additional weekly energy expenditure of 2000-2500 kcal or an additional daily energy expenditure of approx.…”

“…16 However, it has to be pointed out that paraplegic athletes develop relatively high metabolic intensities in competition and that the variability of their physiological parameters is considerably high. 4 Therefore, general recommendations aiming at the control of their training intensities can only be given if the respective individual prerequisites are taken into account and if the athletes undergo regular scientific investigations to verify their efficiency.…”

“…Furthermore, from the point of view of sports medicine, handbiking is highly recommended to maintain the level of physical fitness and to prevent arteriosclerotic diseases as it is characterized by a relatively high energy consumption at moderate training intensities. 4 In addition to the justdescribed modified bikes, more and more handbikes are being developed for the purpose of being used in sports.…”

Study design: Case study in handbiking under competition conditions. Objective: To investigate exercise-induced, metabolic, pulmonary, cardiovascular and energetic reactions of a paraplegic athlete during a city marathon. Setting: City marathon Cologne, Germany. Subject: We tested a 27-year-old male athlete from the German national team. The handicap of the athlete was a complete traumatic spinal cord injury ASIA/IMSOP Grade A at the level of the fourth thoratic vertebra (Th 4 ). Method: In the competition, the athlete used his own race handbike whose crank system had been exchanged for a power measurement system with registering option. For measuring ventilatory gas parameters during exercise, a portable spirometric system was used. The athlete managed to finish the marathon race in 1:48:54 h. Results: The mean oxygen uptake ( . VO 2 ) during the marathon was 1580 ml/min, with a maximum value of 2535 ml/min. The mean heart frequency was 137 bpm with a maximum of 157 bpm. During the race the mean energy consumption was 463 kcal/h with a maximum of 758 kcal/h. Prior to the race, the blood lactate value was 2.9 mmol/l; after 10 km 4.4 mmol/l; after 20 km 2.9 mmol/l, and after 30 km 2.9 mmol/l. Conclusion: Competition-oriented handbikers should concentrate on exercise units of long duration at low intensities -like marathon runners or cyclists -in order to improve their aerobic performance capacity. However, it has to be pointed out that paraplegic athletes develop relatively high metabolic intensities in competition and that the variability of their physiological parameters is considerably high.

The uses of mobility aids are critical to the lives of millions of people around the world with mobility impairments. Mobility aids, whether it is a wheelchair, a walker, or a prosthetic limb, give their users the independence in their everyday lives to work, play, and perform their activities of daily living. Properly prescribed mobility aids also assist in the safety of their users by reducing falls, and reducing fatigue and injuries to the upper extremities. The dramatic advancements in technology in the past decades have allowed mobility aids to be accessible to a far greater population of users, and have given users, even those with very limited functional mobility, the means to participate in whichever activities they please and also to perform their normal daily activities.
