RESUMO

Diversos estudos evidenciam que a fadiga muscular local diminui a propriocepção articular. Contudo, poucos estudos investigaram o efeito de protocolos funcionais, nos quais o exercício realizado se aproxima das exigências da actividade desportiva. O objectivo do presente estudo consistiu na avaliação, em andebolistas, do efeito da fadiga muscular local aguda induzida por exercício envolvendo a habilidade específica de remate em apoio na sensação de posição do ombro. A amostra foi constituída por 24 atletas do sexo masculino. A sensação de posição do ombro foi avaliada, antes e imediatamente após exercício, através da técnica de reposicionamento activo de uma posição passivamente determinada e foi reportada usando como indicadores o erro angular absoluto, o erro relativo, e o erro variável. O protocolo de exercício para induzir fadiga consistiu na execução de remates de sete metros, em apoio, à velocidade máxima. Os atletas terminavam o exercício quando reportavam um valor ≥15 na Escala de Borg. Os atletas testados realizaram em média 59.96±12.97 remates excedendo o valor 15 (16.9±0.68) da Escala de Borg. Após exercício, o erro angular absoluto aumentou (2.53±1.10 vs 3.46±1.64; p=0.03) e diminuiu a fiabilidade das tentativas de reposicionamento, como o demonstra o aumento do erro variável em 37.7%. Os resultados do presente estudo indicam que a fadiga muscular induzida por exercício envolvendo a habilidade específica de remate tem efeitos deletérios na sensação de posição do ombro de andebolistas.

ABSTRACT

Skeletal-muscle fatigue decreases shoulder position sense in handball players

Literature indicates that local muscle fatigue diminishes joint proprioception. However, few studies have been conducted investigating the effect of functional protocols, more close to the demands of the sport activity. The purpose of the present study was to assess the effect, in handball players, of exercise-induced acute muscle fatigue using a specific motor task, handball shot, on the shoulder joint position sense. The sample was composed by 24 male athletes. Shoulder position sense was evaluated, prior to and immediately after exercise using the technique of active positioning of a passively determined position, and was reported as absolute, relative and variable angular errors. The exercise protocol to induce fatigue consisted on repeated shots from a 7 meters distance to goal with maximum velocity. Athletes finished the exercise when a level ≥ 15 on the Borg scale was reached. The athletes performed in average 59.96±12.97 shots, reaching or exceeding the scores of 15 (16.9±0.68) on the Borg scale. After exercise, the absolute angular error increased (2.53±1.10 to 3.46±1.64; p=0.03) and the reliability in estimating shoulder angles decreased, as showed by the increase (37.7%) in variable error. The results of the present study suggest that muscle fatigue induced by the specific motor task of handball shot has deleterious effects on shoulder joint position sense in handball players.
