Resumen
Introduction: The aim of this study was to investigate
the effects of high intensity resistance circuit (HIRC) and
traditional strength training (TST) on neuromuscular fatigue and
metabolic responses. Methods: Twelve trained young subjects
performed HIRC and TST in a counterbalanced order with 1
week rest in-between. The amount of workload and the interset
time for each local muscle group were matched (180 s),
however, the time between successive exercises differed. The
twitch interpolation technique was used to test neuromuscular
function of the knee extensor muscles. Blood lactate concentration
was used to evaluate metabolic responses. Results: Maximum
voluntary contraction and resting potentiated twitch
amplitude (Qtw) were significantly reduced after HIRC, but there
were not changes after TST, while reductions in voluntary activation
were similar. Lactate concentration increased significantly
more after HIRC. Conclusions: The higher lactate concentration
after HIRC ...
