Influence of Certain Motor Abilities on Ball Throwing Velocity in Goalball: A Pilot Study

Abstract

The aim of the research was to determine the influence of sprint performance and explosive strength on ball throwing velocity in Goalball. The sample of participants consisted of 12 nationally and internationally ranked Goalball players, with an average age of (25.17±8.03). To evaluate sprint performance, the 5 and 10 meter sprint tests were used. To evaluate explosive strength, the standing long jump and seated medicine ball throw were used. The results of the regression analysis have indicated that the entire system of applied variables is statistically significantly connected and influences ball throwing velocity. At the same time, we evaluated the statistically significant influence of the seated medicine ball throw variable. We can conclude that as part of the fitness training of Goalball players, it is necessary to work on improving sprint performance and explosive strength due to the ability of rapid transition of the players from the defensive phase to the attack phase. It is especially important to develop upper-body explosive strength in order to increase ball throwing velocity and create the possibility for greater effectiveness of Goalball players.

Attack and Defense Performance in Goalball: A Proposal for Throwing, Balance and Acoustic Reaction Evaluation

“…Upper and lower limb strength is a determinant in the game due to its relevance in throwing [ 6 , 7 ]. A significant relationship between seated medicine ball throw and throwing velocity has been found in previous studies in goalball players [ 8 ]. Core muscles, responsible for maintaining spine and pelvis stability, are also considered relevant in overhead throwing.…”

The Relationship Between Playing Sports and Self-Efficacy in People With Disabilities

“…Many sports are primarily intended for people with disabilities. Goalball, designed in 1946 by Hanz Lorenzen and Sepp Reindletog (Jorgić, Grbović, Đorđević, Stanković, & Stanković, 2019) is considered the "identity card" of blind and partially sighted people. It is designed to be a part of the rehabilitation of veterans with a visual impairment from the Second World War (Aleksandrović, Jorgić, & Mirić 2016).…”

Efeito da fadiga sobre o desempenho no goalball

“…Primeiramente, mesmo que a força dos membros inferiores seja fundamental para que a velocidade da bola no arremesso seja maior (Goulart-Siqueira et al, 2019;Jorgić et al, 2019), deve-se reconhecer que a fadiga dos músculos extensores do joelho não é necessariamente representativa da fadiga do corpo todo e não representa totalmente o desempenho no goalball.…”

“…De fato, a força explosiva de membros inferiores e o desempenho do sprint estão fortemente correlacionados à velocidade da bola no arremesso do goalball (Goulart-Siqueira et al, 2019;Jorgić, Grbović, Đorđević, Stanković, & Stanković, 2019), pois os jogadores de goalball devem ser capazes de acelerar e desacelerar rapidamente a uma curta distância para realizar o arremesso (Monezi et al, 2018), causando fortes contrações estáticas e dinâmicas dos músculos dos membros inferiores.…”

“…Caraterizado por um ciclo de sucessivas ações de ataque e defesa (Morato et al, 2012), o goalball tem no arremesso, especialmente nos mais rápidos (Morato et al, 2018), uma ação técnica determinante para o resultado de uma partida. Todavia, apesar de a força da musculatura dos membros superiores ser essencial durante a execução dos arremessos (De Campos et al, 2020), a força explosiva de membros inferiores e o desempenho do sprint apresentam forte correlação com a velocidade da bola (Goulart-Siqueira et al, 2019;Jorgić et al, 2019), pois os jogadores devem ser capazes de acelerar e desacelerar rapidamente a uma curta distância para realizar o arremesso (Monezi et al, 2018), causando fortes contrações estáticas e dinâmicas dos músculos dos membros inferiores. Diante dessas informações, parece particularmente relevante investigar a fadiga neuromuscular dos músculos extensores do joelho induzida por jogos consecutivos de goalball.…”
