It has not yet been demonstrated that the propulsion technique used was identical on a treadmill and in the field, especially because of the movement of “steering” on the field during Asy propulsion. The aim of this study is to compare biomechanical and physiological responses of Asy during tests on the field vs. treadmill. Material and method Ten wheelchair basketball players performed 1 session of 4 minutes at 8 km.h−1 on the treadmill and 1 session on the field (‘figure 8’ tests). The MWC is equipped with an instrumented wheel allowing measuring temporal parameters: push time (PT), recovery time (RT) and cycle time (CT = PT + RT). Push frequency (PF), Rate of Rise (RoR), Fraction of Effective Force (FEF) and Rolling Resistance (RR) are also measured. Each subject is equipped with a K4, allowing to obtain the consumption of oxygen (VO2 kg−1). Results The parameters collected are presented in Table 1 . Conclusion Although the RR is higher for treadmill, Vo2.kg−1 and PT are superior on the over-ground. This can be explained by the steering on the field, which induces an increased use of the trunk muscles for stability. This could also explain lower PF and RoR. Therefore, field test is recommended to evaluate Asy propulsion.

Materials and method Eight highly trained wheelchair basketball players have performed an incremental multistage field test in two separate sessions (synchronous and asynchronous). The number of exercise levels performed, maximal aerobic velocity, rating of perceived exertion and arm frequency were measured. Results The number of exercise levels performed and maximal aerobic velocity are significantly increased in the synchronous mode (P < 0.05) and arm frequency is significantly higher in synchronous versus asynchronous at 100% maximal aerobic velocity. There is a significant correlation between both modes of propulsion for the number of exercise levels performed (r2 = 0.80). However, normalized rating of perceived exertion values at each maximal aerobic velocity percentage shows no significant difference whatever the mode of propulsion, even if the absolute value of rating of perceived exertion tends to be higher in asynchronous versus synchronous at each stages. Conclusion Synchronous mode provides better performance than asynchronous, in terms of number of exercise levels performed and maximal aerobic velocity. Arm frequency could restrict athletes’ performance in asynchronous propulsion during the final stage. It would be interesting for futures studies to assess both physiological and biomechanical parameters simultaneously.

Maximal wheelchair linear velocity has previously been observed to be reached after the release of the handrims both during sports activities and daily life propulsion. This paper provides a combined analysis of linear velocity and trunk kinematics in elite wheelchair racing athletes during straight-line propulsion at stabilized speeds. MWC and trunk kinematics of eight athletes (level: 7 elite, 1 intermediate; classification: T54 (5), T53 (2) and T52 (1)) were monitored during 400 m races using inertial measurement units. An average propulsion cycle was computed for each athlete. The main finding of this article is the difference in propulsion patterns among the athletes, exhibiting either 1, 2 or 3 peaks in their velocity profile. A second peak in velocity is usually assumed to be caused by the inertia of the tru...

Athletes’ mechanical capacities can be evaluated on the field or in lab conditions. However, no studies have indicated a relationship between ergometers and field FVR or performances. Understanding para-athletes’ upper limb FVR can provide important insights for developing effective training programs and improving athletic performance in wheelchair bas-ketball players. Twenty-three wheelchair basketball players (12 women and 11 men) from French national teams performed a battery of three tests consisting of a 20 m sprint (SP) with Inertial measurement units (IMU) on wheels, a horizontal upper limb push-offs on a frictionless sled with two Kistler force plates (HBP), and a crank ergometer sprints test (CES) derived from arm er-gometer sprints using Brachumera, Lode. For th...

Studies of interlimb asymmetry in the lower limbs have shown high between‐subject variability that does not depend on the side of dominance and that does not change with fatigue. Upper limb asymmetry is particularly large in manual wheelchair athletes with a lower degree of impairment. The aim of this study was to evaluate interlimb asymmetry of forces developed during an upper limb Wingate anaerobic test, the effects of fatigue on force, and differences between high‐ and low‐point players.MethodTwenty‐five wheelchair basketball players (13 females and 12 males) of male and female national French teams performed a 30s anaerobic Wingate test on an arm ergometer. Participants were classified into two functional categories, high‐point (classed from 3 to 4.5) and low‐point (classed from 1 to 2.5), according to the International Wheelc...

Performance of wheelchair rugby players is related to several parameters, however it is currently unclear if differences in performance are related to wheelchair type or no: the effect of wheelchair type on performance variables has not been evaluated. The aim of this study was to compare offensive and defensive wheelchairs on performance variables during a straight-line sprint.MethodsThirteen able-bodied people performed two 20 m sprint trials: one with an offensive and one with a defensive wheelchair. Data were collected using inertial measurement units fixed on the wheelchair. Peak wheelchair velocities and left-right asymmetries in peak wheel velocities were measured during the acceleration and constant peak velocity phases. Sprint time, cycle frequency, and mean and maximum velocity were calculated over the entire sprint.ResultsThe ...
