Força muscular e massa corpórea de ratos Wistar

Abstract

A utilização de ratos em pesquisas que procuram verificar os efeitos do exercício físico é bastante comum, inclusive em trabalhos que fazem uso de sobrecarga. Entretanto, a correta determinação da carga de treinamento é fundamental para o sucesso do trabalho. Assim, objetivando verificar a correlação da massa corpórea de ratos Wistar com sua respectiva força muscular e a correlação do teste de 1RM com o teste de número de repetições, 40 ratos Wistar, com 90 dias de idade e pesando em média 220 gramas, foram submetidos a um programa de adaptação ao meio líquido e, em seguida, a testes para determinação da força máxima e submáxima. Depois de mensurada a massa corpórea total e a força muscular, foi possível observar que ocorre relação diretamente proporcional entre a força máxima e a massa corporal total em 0.97 (P≤0,01), sendo a força muscular máxima equivalente a 109% da massa corpórea total. Entre a força muscular submáxima e a massa muscular também se verificou correlação diretamente proporcional entre as variáveis; o que nos permite concluir que o teste de força submáxima e a massa corpórea total são ferramentas eficazes na determinação da carga de treinamento de ratos Wistar.

The use of rats in studies that seek to monitor the effects of physical exercise is fairly common, even in works that make use of overload. However, the correct determination of the training load is critical to success of studies. Thus, with the objective of verifying the correlation of total body mass of the rats with their respective strength, and the correlation of the 1RM test with test repetitions, 40 rats, 90 days old and weighing average 0,49 pounds underwent a program of adaptation to the water and then were subjected to tests to determine the maximal and submaximal loads. After measuring the total body mass and maximal and submaximal strenght, it was possible to observe directly proportional relationship between maximum strenght and total body mass of 0.97 (P ≤ 0.01), being the maximum muscle strength equivalent to 109% of the total body mass. Between muscle strength and mass submaximal muscle strength was also found direct correlation between the variables, allowing to conclude that the submaximal strength test and total body mass are effective tools in determining the training load of rats.
