Resumo: | Physiological effects of thermal changes in tissues might influence some physical properties of muscle fibers, such as strength. The aim of this study was to compare the effects of cryotherapy and microwave diathermy application on the strength production capacity of the elbow flexor muscles. Thirty male, healthy and sedentary subjects, with average age of 22.40 (±3.42) years, participated in this prospective study. Participants were submitted to assessment of isometric strength production capability by an adapted load cell. Half of volunteers received cryotherapy on the first day of application and microwave diathermy (MD) 48 hours later, whereas the other half was treated the other way around. Cryotherapy was applied up to the temperature of the biceps region reached 25ºC, and MD was applied up to 42ºC. Six peak strength reevaluations were made over 2 hours. There was significant increase in peak strength (PS) up to 15 minutes after cryotherapy, then there was a decrease in maximum isometric strength, however, statistically significant difference remained up to 1 hour and 30 minutes after cryotherapy. In MD, PS decreased significantly after application until 15 min. From this moment, PS returned close to the initial value, and in the last assessment, PS reduced again. Cryotherapy and MD differently interfered in isometric muscle strength production capacity of elbow flexors, while cooling generated increment, heating caused decline. |

O objetivo deste estudo foi comparar os efeitos da aplicação da crioterapia e da diatermia por micro-ondas (DMO) sobre a capacidade de produção de força dos músculos flexores de cotovelo. Participaram deste estudo prospectivo 30 voluntários do sexo masculino, saudáveis, não praticantes de atividade física, com valor médio de 22,40 (±3,42) anos de idade. Foram submetidos à avaliação da capacidade de produção de força isométrica, por meio de uma célula de carga adaptada. Metade dos voluntários recebeu no primeiro dia aplicação da crioterapia e no outro dia (48 horas depois) a DMO, e a outra metade dos sujeitos o inverso. A crioterapia foi aplicada até que a temperatura na região bicipital atingisse 25ºC e a DMO foi aplicada até que atingisse 42ºC. Seis reavaliações do PF foram feitas ao longo de 2 horas. Houve incremento significativo no pico de força (PF) até 15 minutos após a aplicação da crioterapia, a partir desse momento houve decréscimo da força isométrica máxima, no entanto, a diferença estatisticamente significativa esteve presente até 90 minutos depois. Na DMO, o PF reduziu significativamente até 15 min após a aplicação do recurso. A partir deste momento, o PF foi retornando próximo ao valor inicial. Na última avaliação, o PF reduziu novamente. A crioterapia e a DMO interferiram de maneira diferente na capacidade de produção de força muscular isométrica de flexores de cotovelo, enquanto o resfriamento gerou incremento, o aquecimento causou declínio.Universidade Federal de Santa Catarina.
