title: The influence of high-velocity resistance circuit training on aerobic power*.
abstract: * This work was supported by the Natural Sciences and Engineering Research Council. This study was designed to investigate the influence of high-velocity resistance circuit training on maximal aerobic power. Twenty-seven trained males participated either as training (N = 16) or control (N = 11) subjects. The training group exercised for two 20 sec sets at each of six stations of hydraulic, variable resistance apparatus over two or three circuits maintaining an exercise:relief ratio of 1:2 during each circuit. Subjects trained four times weekly over 5 weeks. The resistance at each station was adjusted as necessary to maintain consistent angular limb velocities of approximately 3.2 rad/sec. The VO2max for the training group was increased (p < 0.001) by 9.5% when expressed in either absolute or relative terms. No changes were observed for control subjects. Oxygen consumption responses measured over two circuits for six training group subjects averaged 61 and 57% of VO2max for exercise and relief intervals, respectively. It is therefore suggested that the hydraulic circuit resistance program described will elicit a metabolic intensity sufficient to improve aerobic power, even in previously trained subjects.J Ortho Sports Phys Ther 1988;9(10):339-344.
