Correlação entre a dinamometria e teste funcional em atletas de handebol

Abstract

RESUMOIntrodução: São poucas as informações que relacionam testes funcionais com testes mais precisos, como a dinamometria isocinética. Objetivo: Correlacionar as variáveis isocinéticas pico de torque (PT), potência média (PM) e trabalho total (TT) de rotadores internos de ombro em atletas de handebol do gênero masculino com o teste funcional de arremesso de medicine ball (AMB). Métodos: Participaram desse estudo 25 atletas amadores de handebol do gênero masculino com idade média 17,72 ± 2,16 anos. A coleta de dados foi realizada em dois dias diferentes, respeitando intervalo mínimo de 48 horas entre as sessões. De maneira aleatória, definida por sorteio, os atletas faziam o teste isocinético ou o teste de AMB. Para o teste de AMB, o atleta deveria arremessar uma medicine ball de 3 kg a maior distância possível. Para análise isocinética, foram utilizadas as velocidades de 60°/s e 180°/s avaliando a capacidade muscular dos músculos rotadores internos de ombro. Para análise de associações foram utilizados os testes de correlação de Pearson e regressão linear simples. Resultados: Foram observadas associações moderadas (0,60 ≤ r < 0,70; p<0,05) para as variáveis PT, PM e TT e o teste de AMB na velocidade de 60°/s. Além disso, observaram-se associações altas (r ≥ 0,70; p<0,05) entre as variáveis estudadas na velocidade de 180°/s. Conclusão: As variáveis isocinéticas PT, PM e TT, de rotadores internos de ombro do braço dominante de atletas de handebol do gênero masculino apresentam correlação moderada a alta com o teste funcional de AMB.Palavras-chave: ombro, torque, dinamômetro de força muscular. ABSTRACT Introduction: There is little information that correlates the functional tests with more accurate tests such as isokinetic dynamometry. Objective: To correlate the isokinetic variables peak torque (PT), mean power (MP) and total work (TW) of the internal rotators of the shoulder in male handball athletes, through the medicine ball throw (MBT

Physical fitness of amateur paddle players: comparisons between different competitive levels

“…The physical fitness components were evaluated for upper and lower limbs power, handgrip endurance, agility, and aerobic fitness. Upper limbs power was evaluated by 3kg medicine ball throwing (Silva, Penido, Junior, Souza, & Villaverde, 2014), lower limbs power by Squat Jump (Markovic, Dizdar, Jukic, & Cardinale, 2004) with a contact mat (Jump System, CEFISE®, Nova Odessa, Brazil), handgrip endurance strength hold from a validated protocol with hidraulic dynamometer (Bonitch-Góngora, Almeida, Padial, Bonitch-…”

“…The upper limbs power was evaluated through Medicine Ball Throwing (MBT), which was performed with the dominant hand, with the participant sitting in a chair leaning against a wall with his feet on the ground (Silva et al, 2014). The subjects positioned themselves with the trunk resting on the back of the chair held by a strip below the chest.…”

“…The subjects positioned themselves with the trunk resting on the back of the chair held by a strip below the chest. The 3kg medicine ball was held by the subject with a 90° elbow flexion and abduction and then thrown as far as possible over an inextensible demarcation (Silva et al, 2014). The performance was evaluated by the distance in Physical fitness in amateur paddle tennis | 45 meters between the front feet of the chair and the first contact of the ball on the ground.…”

“…The performance was evaluated by the distance in Physical fitness in amateur paddle tennis | 45 meters between the front feet of the chair and the first contact of the ball on the ground. Three trials were performed with a three minutes interval between them and the mean value for the final result of the test, which showed a statistically significant correlation of 0,73 (p<0,001) with power produced in isokinetic dynamometry at 180°/s (Silva et al, 2014).…”

Exploration of the Shoulder Internal Rotation’s Influence on Throwing Velocity in Handball Players: A Pilot Study

“…The correlation between shoulder strength and throwing velocity is currently not well established in the literature [ 12 , 18 , 19 ], although an increase in muscle strength has been shown to improve throwing velocity [ 20 ] and for implementing shoulder-strengthening programs [ 21 ]. The lack of scientific consensus on this topic might be explained by the different methods used to assess shoulder muscle strength.…”
