Study design: Cross-over study. Objective: To determine the effect of strenuous wheelchair exercise on oxygen uptake ( . VO 2 ), muscle activity and propulsion cycle timing (including the push time and recovery time during one full arm cycle). Setting: Laboratory of Sport Sciences at the University of France-Comte in France. Methods: Two exercise bouts of 6-min duration were performed at a constant workload:(1) non-fatigable exercise (moderate workload) and (2) fatigable exercise (heavy workload). Measurement of .VO 2 , surface electromyographic activity (EMG) from shoulder muscles, and temporal parameters of wheelchair ergometer propulsion were collected from eight able-bodied men (2674 years). Results: A progressive increase in .VO 2 associated with EMG alterations (Po0.05), and a decrease of the cycle and recovery time (Po0.05) during the heavy exercise. Whereas the push time remained constant, an increased muscle activation time (Po0.05) was found during heavy exercise. Conclusion: Observations during wheelchair ergometry indicate the development of fatigue and inefficient muscle coordination, which may contribute to deleterious stress distributions at the shoulder joint, increasing susceptibility to injury.

“…The significant group variability indicates that there is considerable room for improvement. In addition, gross ME during propulsion has been shown to rarely surpass 11%, which also suggests improvements in technique may be attainable (52). These findings may have meaningful and clinically significant implications because propulsion occurring inefficiently may place a person at significant risk for developing upper extremity pain and injury.…”

Background/Objective: As considerable progress has been made in laboratory-based assessment of manual wheelchair propulsion biomechanics, the necessity to translate this knowledge into new clinical tools and treatment programs becomes imperative. The objective of this study was to describe the development of a manual wheelchair propulsion training program aimed to promote the development of an efficient propulsion technique among long-term manual wheelchair users. Methods: Motor learning theory principles were applied to the design of biomechanical feedback-based learning software, which allows for random discontinuous real-time visual presentation of key spatiotemporal and kinetic parameters. This software was used to train a long-term wheelchair user on a dynamometer during 3 low-intensity wheelchair propulsion training sessions over a 3-week period. Biomechanical measures were recorded with a SmartWheel during over ground propulsion on a 50-m level tile surface at baseline and 3 months after baseline. Results: Training software was refined and administered to a participant who was able to improve his propulsion technique by increasing contact angle while simultaneously reducing stroke cadence, mean resultant force, peak and mean moment out of plane, and peak rate of rise of force applied to the pushrim after training. Conclusions:The proposed propulsion training protocol may lead to favorable changes in manual wheelchair propulsion technique. These changes could limit or prevent upper limb injuries among manual wheelchair users. In addition, many of the motor learning theory-based techniques examined in this study could be applied to training individuals in various stages of rehabilitation to optimize propulsion early on.

“…The gross M E was calculated during submaximal steady-stale exercise "by dividing the internally liberated mechanical power, which was assumed (to be equal to V G 2, into external power out put ( VI7 ): M E -W / (V Q 2 x340), in which 340 W has been shown lo be the power equivalent for 1 1 O^-min"1 (Gaesser and Brooks 1975;Stainsby et al 1980;Van Der Woude et al 1988;Linden et al, 1993).…”
