Joint angle specificity of fixed mass versus hydraulic resistance knee flexion training

Academic Article


  • Ten untrained 18- to 22-year-old subjects trained one leg using isoinertial fixed-mass (FM) and the other leg using hydraulic resistance (HR) to determine the effect on the torque-position knee flexion curve. Three sets of 10 reps were performed three times a week for 8 weeks. Strength was evaluated using a 1-RM test at 60 and 240°/sec isokinetically. Both legs increased in 1-RM and isokinetic strength. The FM leg increased more than the HR leg in the 1-RM test and across the range of motion for both isokinetic test velocities. Increases in strength were similar at the different joint positions in the range of motion for both legs. The results indicate that FM training can increase strength at the strongest as well as the weakest points in the range of motion, and that at least for this training protocol and this population of subjects, FM training may induce greater increases in strength than HR training. © 1995 National Strength & Conditioning Association.
