“…19 The corresponding impaired work capacity of SCI individuals compared to able-bodied persons can be attributed to the smaller active muscle mass available for physical performance. 20 It has been shown in SCI persons that the kind of sitting position 21 and the kind of upper body exercise 22 may influence muscle efficiency and force production during exercise. During handbike cycling, the athlete is sitting on a chair, the upper body is fixed on the bench and only the muscles of the shoulders and arms are mainly involved in exercise.…”

Study design: Energy expenditure (EE) and fat oxidation in handbike cycling compared to cycling in order to determine the intensity that elicits maximal fat oxidation in handbike cycling. Objective: To establish the exercise intensity with the highest fat oxidation rate in handbike cycling compared with cycling (control group) in order to give training recommendations for spinal cord-injured (SCI) athletes performing handbike cycling. Setting: Institute of Sports Medicine, Swiss Paraplegic Centre, Nottwil, Switzerland. Methods: Eight endurance-trained handbike cyclists (VO 2 peak handbike cycling 37.577.8 ml/kg/ min) and eight endurance trained cyclists (VO 2 peak cycling 62.574.5 ml/kg/min) performed three 20-min exercise blocks at 55, 65 and 75% VO 2 peak in handbike cycling on a treadmill or in cycling on a cycling ergometer, respectively, in order to find the intensity with the absolutely highest fat oxidation. Results: The contribution of fat to total EE was highest (39.1716.3% EE) at 55% VO 2 peak in handbike cycling compared to cycling, where highest contribution of fat to EE (50.8713.8%) was found at 75% VO 2 peak. In handbike cycling, the highest absolute fat oxidation (0.2870.10 g/min) was found at 55% VO 2 peak compared to cycling, where highest fat oxidation (0.6770.20 g/min) was found at 75% VO 2 peak. Conclusion: Well-trained handbike cyclists have their highest fat oxidation at 55% VO 2 peak handbike cycling compared to well-trained cyclists at 75% VO 2 peak cycling . Handbike cyclists should perform endurance exercise training at 55% VO 2 peak handbike cycling , whereas well-trained cyclists should be able to exercise at 75% VO 2 peak cycling . For training recommendations, the heart rate at 55% VO 2 peak handbike cycling lies at 13576 bpm in handbike cycling in SCI compared to 147714 bpm at 75% VO 2 peak cycling in well-trained cyclists. We presume that the reduced muscle mass involved in exercise during handbike cycling is the most important factor for impaired fat oxidation compared to cycling. But also other factors as fitness level and haemodynamic differences should be considered. Our results are only applicable to well-trained handbike cyclists with SCI and not for the general SCI population.

“…Although a number of studies have been conducted to examine the stroking characteristics of racing wheelchair propulsion (Higgs, 1986;Goosey et al, 1997Goosey et al, , 1998Goosey et al, , 2000Goosey-Tolfrey et al, 2001;Ridgway et al, 1988;Chow et al, 2000Chow et al, , 2001Cooper, 1990;Gehlsen et al, 1990;Maˆsse et al, 1992;O'Connor et al, 1998;Wang et al, 1995;Veeger et al, 1989;Woude et al, 1988), only one study has presented data related to wheelchair sprinting. Moss et al (2005) analyzed the first six strokes of a sprint start in over-ground racing wheelchair propulsion of an international male wheelchair athlete and concluded that ''racing wheelchair sprint propulsion is a complex form of locomotion and cannot be described accurately by using just the established definitions of a propulsive and a recovery phase.''…”
