“…Furthermore, outside International Paralympic Committee events, the European Handcycle Circuit includes able-bodied athletes in its championships-this further boosts the sport's development and increases interest in handcycling for the nondisabled. In this handcycling study, the calculated FEF 2D value (85%) is higher than the values existing in manual wheelchair propulsion ranging from 47% (Wu et al, 1998) to 81% (Veeger et al, 1992). It consequently seems that, regardless of a participant's experience, force application is highly efficient in handcycling.…”

The aim of this study was to investigate muscle activity, kinematic, and handgrip-force pattern generation during handcycling. One able-bodied participant performed a 1-min exercise test on a handcycle at 70 revolutions per minute. This article proposes an original data collection and analysis methodology that gathers synchronized kinematics, kinetics, and electromyography. Such data, which most often appear complex, are easily summarized using this methodology. This preliminary study has an new setup and offers good indications on the biomechanical pattern for handcycling movement analysis.

“…The collection of bilateral 3D kinematics (e.g., Rao et al, 1996; Shimada et al, 1998) eventually became standard with the proliferation of multi-camera systems. By this time, instrumented wheels and other devices that allow the measurement of handrim kinetics had also been developed (e.g., Asato et al, 1993; Rodgers et al, 1994; Wu et al, 1998). However, many current laboratories are equipped with only one instrumented wheel due to the high cost of these devices (e.g., Hurd et al, 2008a).…”

Studies of manual wheelchair propulsion often assume bilateral symmetry to simplify data collection, processing, and analysis. However, the validity of this assumption is unclear. Most investigations of wheelchair propulsion symmetry have been limited by a relatively small sample size and a focus on a single propulsion condition (e.g., level propulsion at self-selected speed). The purpose of this study was to evaluate bilateral symmetry during manual wheelchair propulsion in a large group of subjects across different propulsion conditions. Three-dimensional kinematics and handrim kinetics along with spatiotemporal variables were collected and processed from 80 subjects with paraplegia while propelling their wheelchairs on a stationary ergometer during three different conditions: level propulsion at their self-selected speed (free), level propulsion at their fastest comfortable speed (fast), and propulsion on an 8% grade at their level, self-selected speed (graded). All kinematic variables had significant side-to-side differences, primarily in the graded condition. Push angle was the only spatiotemporal variable with a significant side-to-side difference, and only during the graded condition. No kinetic variables had significant side-to-side differences. The magnitudes of the kinematic differences were low, with only one difference exceeding 5°. With differences of such small magnitude, the bilateral symmetry assumption appears to be reasonable during manual wheelchair propulsion in subjects without significant upper-extremity pain or impairment. However, larger asymmetries may exist in individuals with secondary injuries and pain in their upper extremity and different etiologies of their neurological impairment.

“…Peak elbow extension torques were 10 Nm. They also reported the largest torques around the shoulder joint, but predominantly as a shoulder flexion torque [24]. A large shoulder flexion torque of approximately 30 Nm and elbow extension torque of approximately 10 Nm were also calculated in other study [25].…”
