Relationship between Sprint Velocity and Peak Moment at Shoulder and Elbow in Elite Wheelchair Basketball Players

Abstract

Specific wheelchair basketball (WB) skills on the court have been poorly analyzed in relation to improving players’ performance according to their functional class. The purpose of this study was to evaluate the associations between maximum velocity (Vmax) and peak moment (PM) in the shoulder and elbow joints in specific WB skills and to compare performance between the main two groups by functional class. Twelve male WB players, divided in categories A (functional classes 1.0–2.5) and B (class 3.0–4.5), performed a sprint test battery composed by four tests (with and without ball) and isokinetic tests. A significant relationship between PM of the internal and external shoulder rotation and the flexion and extension elbow with Vmax (p < 0.05) was found. During a 5 m backward sprint test, category B was faster in the last three meters than category A (p < 0.05) and also for the rest of the test but p = NS. Category B showed higher PM than category A for internal shoulder rotation (ISR) at 60 °/s and at 180 °/s on the dominant side (DS) (p < 0.05). In conclusion, ISR on the DS was found different for both groups and showed significant relationship with Vmax in all of the tests performed. Moreover, at higher speeds the elbow flexion and extension in DS were correlated with Vmax in all the actions with ball (passing, bouncing, and braking) reflected the importance of these joints movements in acquiring speed when performing sport specific WB skills.

[Id 57089] Análise Correlacional Do Desempenho Funcional E Muscular Do Ombro De Atletas De Basquete Em Cadeira De Rodas E Regular

“…Em específico para os atletas cadeirantes, a análise da musculatura rotadora externa e interna do ombro é ainda mais importante, visto que, além de ser a responsável por estabilizar a articulação do ombro nos movimentos acima da cabeça 22 , esses músculos são os que iniciam a propulsão da cadeira de rodas 23 A comparação entre os membros é de extrema importância, uma vez que desequilíbrios de força muscular indicam um risco maior de lesões 18 . As assimetrias entre os membros podem estar relacionadas aos arremessos repetitivos em muitos esportes, o que causa um maior desenvolvimento dos músculos do ombro no MD 22 .…”

Rendimiento físico de atletas varones de élite de baloncesto en silla de ruedas de la región del Biobío-Chile en inicio del período preparatorio: estudio transversal (Physical performance of wheelchair basketball athletes with Paralympic projection of th

“…Los atletas de BSR deben presentar óptima performance en su capacidad de aceleración y velocidad máxima, por considerarse como variables determinantes en la referida modalidad (Villacieros et al,2020). La prueba de sprint en distancia de 20 metros está asociado a la velocidad de aceleración y máxima de atletas en silla de ruedas (Vandanlewijck et al, 1999) y puede ser considerado como una prueba control para monitorear el desempeño de los atletas de BSR (Loturco et al, 2020).…”

“…Por lo tanto, si bien, el entrenamiento y la experiencia técnica contribuyen en obtener mejores resultados en sprint de cortas distancias, la funcionalidad posee un rol más importante. En ese sentido, Villacieros et al (2020) destacan la importancia e influencia de los niveles de fuerza de las musculaturas de rotación de hombro, flexión y extensión de codo, en miembros dominantes, para adquisición de mayores niveles de velocidad máxima en los atletas de BSR, así como en acciones como pasar, botear y frenar. Loturco et al (2020) evaluaron 11 atletas varones de élite brasileños con CD superior 3.0 y el valor promedio para T20m fue de 3,83±0,31.…”

Evaluation of the Biomechanical Parameters of Human-Wheelchair Systems during Ramp Climbing with the Use of a Manual Wheelchair with Anti-Rollback Devices

“…Calm implementation of successive propulsion phases with greater force (as a result of the use of an anti-rollback device) may be subjectively perceived by the user as seemingly easier than more dynamic and chaotic propulsion of the wheelchair in such a way that it does not roll back while climbing the ramp, even if it requires less force (no additional friction in the system). The solution can be beneficial for disabled people with high physical fitness, e.g., athletes [48,49] and people infirm or inexperienced in moving in a wheelchair, as it affects their efficiency while moving [50].…”
