Resumo
Introdução: O treinamento de salto é realizado habitualmente por atletas de voleibol. A fototerapia e a estimulação elétrica neuromuscular (EENM) são recursos eficazes na melhora da performance muscular. Porém, há pouca evidência que compare a utilização
desses recursos no treinamento de salto em atletas de voleibol. Objetivo: Avaliar a
adição da fototerapia e da estimulação elétrica ao treinamento de força muscular e salto
em atletas de voleibol. Métodos: Trinta e seis atletas foram distribuídos aleatoriamente
em 3 grupos (controle, fototerapia e EENM). Os atletas realizaram treinamento de força
muscular e salto associado ou não a fototerapia e a EENM. Os desfechos avaliados
foram: força muscular, habilidade de salto, efeito global percebido e frequência de salto
na linha de base, e nos acompanhamentos de seis e oito semanas. Resultados: Houve
diferença estatisticamente significante na força muscular do membro dominante com
oito semanas de acompanhamento a favor do grupo fototerapia e EENM (diferença
entre as médias = 1,7; IC 95% 1,1 a 2,4 e diferença entre as médias = 2,5; IC 95% 1,8 a
3,2 respectivamente) e diferença significante na força muscular do membro não
dominante a favor do grupo fototerapia e EENM nos acompanhamentos de seis semanas
(diferença entre as médias = 1,8; IC 95% 1,1 a 2,6 e diferença entre as médias = 2,6; IC
95% 1,7 a 3,6 respectivamente) e oito semanas (diferença entre as médias de 2,4;
IC95% 1,7 a 3,1 e diferença entre as médias de 3,7; IC 95% 3 a 4,5 respectivamente).
Os mesmos efeitos não foram observados nos demais desfechos. Conclusão: A
fototerapia e a EENM promovem efeito benéfico no ganho de força muscular, porém
estes efeitos não foram vistos nos desfechos de performance do salto.
Introduction: The jump training is usually done by volleyball players. Phototherapy and neuromuscular electrical stimulation (NMES) are effective resources in improving muscle performance. However, there is little evidence that compares the use of these resources in jump training in volleyball athletes. Objective: To evaluate the addition of phototherapy and electrical stimulation to the training of muscle strength and jump in volleyball athletes. Methods: Thirty-six athletes were randomly divided into 3 groups (control, phototherapy and EENM). The athletes performed strength training and associated jump or not phototherapy and EENM. The outcomes assessed were: muscular strength, jumping ability, overall effect and jump frequency at baseline and 6 and 8 weeks in follow-ups. Results: There were significant differences in muscle strength of the dominant limb with 8 weeks of follow-up in favor of phototherapy group and EENM (difference between means = 1.7, 95% CI 1.1 to 2.4 and difference between means = 2.5; 95% CI 1.8 to 3.2 respectively) and significant difference in muscle strength of the non-dominant limb in favor of phototherapy and EENM group in the 6- week follow-ups (difference between means = 1.8, 95 1.1 to 2.6% and difference between means = 2.6, 95% CI 1.7 to 3.6 respectively) and 8 weeks (difference between the average of 2.4, 95% CI 1.7 to 3 , and one difference between the average of 3.7, 95% CI 3 to 4.5, respectively). The same effects were not observed in other outcomes. Conclusion: Phototherapy and EENM promote beneficial effect on muscular strength gain, but these effects were not seen in the jump performance outcomes.
