MetadataPokaż pełny rekord
The aim of this study was to compare biomechanics and special methods control of judo training process. The study was conducted on eight junior judoists. Special abilities were evaluated using a Special Judo Fitness Test (SJFT). Muscle torque measurements in static conditions were performed. Ten muscle groups were examined: flex¬ors and extensors of the trunk, shoulder, elbow, hip and knee. The maximal power and height of jump were mea¬sured at BCMJ and CMJ jumps. Power-velocity relations were determined from 5 maximal cycle ergometer exer¬cise bouts at increasing external loads equal to 2.5, 5.0, 7.5, 10.0 and 12.5% of body weight. Mean values (±SD) index of Special Judo Fitness Test was 12.71±1.94. The values of BCMJ relative maximal power and height of jump were 44.75±8.97 W·kg–1 and 0.526±0.071 m, respectively. The mean values of Pmax 900.8±152.9 W and Pmax/mass 13.44±1.28 W·kg–1 were corresponding to mean optimal velocity 119.3±16.0 rpm. The relative values of the muscle torque were correlated with index of SJFT, the coefficients ranging from –0.15 to –0.68. Index of SJFT correlated significantly with BCMJ values of the relative power and height of jump (r=–0.72 and –0.88, respectively). SJFT index correlated with power output and velocity in the maximal cycloergometer test, the coefficients ranging from –0.71 to 0.48. In training process should be used biomechanics measurements, physical fitness tests and special fitness tests char¬acteristic for own discipline as well. It will give optimal training control.
