Perfil neuromuscular de atletas de handebol durante curta competição no Brasil

Abstract

-The aim of this study was to assess the neuromuscular profile of handball (TH) players during a short-term condensed competition. Nine TH athletes (age: 23 ± 3 years; height: 176.2 ± 10.5 cm; mass: 75.3 ± 8.6 kg) played 5 handball matches in 5 consecutive days and had exercise-induced muscle damage (EIMD) markers such as soreness (SOR), thigh circumference (CIR), knee range of motion (ROM) and countermovement jump height (CMJ) collected before the first match and at the end of each day of competition. Changes over time in these markers were analyzed. Significant changes were found for all EIMD markers assessed. CMJ significantly decreased at the fourth day of competition when compared to baseline (0.41 ± 0.03 m vs. 0.45 ± 0.02 m). ROM decreased on the first day of competition and remained stable until the last day of competition (baseline: 126.5 ± 7.2º; 1 st day: 115.8 ± 5.9º; 2 nd day: 115 ± 7º; 3 rd day: 113.9 ± 8.8º; 4 th day: 114.4 ± 8.6º). SOR and CIR were increased at the second day of competition and remained altered thereafter. It was concluded that the characteristics of short-term condensed competition have led TH athletes to significant EIMD. If not avoided, EIMD might lead to reductions in performance in the most important (final) matches. Key words: Fatigue; Neuromuscular monitoring; Sports; Wounds and Injuries. (idade: 23 ± 3 anos; estatura: 176,2 ± 10,5 cm; massa: 75,3 ± 8,6 de competição, quando comparado ao valor basal (0,41 ± 0,03 m vs. 0,45 ± 0,02 m). A ADM diminuiu após o primeiro dia de competição e permaneceu comprometida até o último dia (basal: 126,5 ± 7,2º; 1 o dia: 115,8 ± 5,9º; 2 o dia: 115 ± 7º; 3 o dia: 113,9 ± 8,8º; 4 o dia: 114,4 ± 8,6º Resumo -O objetivo do presente estudo foi medir o perfil neuromuscular de jogadores de handebol durante uma competição em formato de jogos. Nove jogadores de handebol kg) jogaram cinco partidas da modalidade em cinco dias consecutivos e tiveram marcadores de DM [como percepção subjetiva de dor (PSD), circunferência da coxa (CIR), amplitude de movimento do joelho (ADM) e altura de salto com contra-movimento (AS)] coletados antes da primeira partida e ao final de cada dia de competição. Mudanças ao longo do tempo nesses marcadores foram analisadas. Alterações significantes foram encontradas para todos os marcadores de DM coletados. A AS diminuiu significantemente durante o quarto dia
