Subjects agreed on the above conditions in writing. Thirteen selleck chemical Carfilzomib judoists (age 18.4��3.1 years, body height 178.6��8.2 cm, body mass 82.3��15.9 kg, BMI 25.65��3.59, FAT% 10.8��4.0 %) volunteered to participate in the study. Maximal muscle torque of ten muscles groups Flexors and extensors of the elbow, shoulder, hip, knee and trunk were measured in static conditions with the use of a special device (Institute of Sport, Poland) Type SMS1 (upper extremities) and SMS2 (lower extremities and trunk) (Jaszczuk et al., 1987). During the measurement of muscle torque of elbow flexors and extensors the subject was sitting, with his arm bent at a right angle and placed on the armrest, and with the trunk stabilized. The muscle torque of shoulder flexors and extensors was measured in a sitting position.

The flexion angle was 70�� and the extension angle 50��. The trunk was stabilized and the chest pressed against the testing station. The measurements of muscle torque of knee flexors and extensors were carried out on subjects in a sitting position. The hip and knee joints were bent at 90��. The subjects were stabilized at the level of anterior iliac spines and thighs, with the upper extremities resting on the chest. The subjects were lying face down during the measurement of the muscle torque of hip extensors, and face up during the measurement of the muscle torque of hip flexors. The hip joint angle remained at 90�� during measurement. The maximal extension of the elbow, knee and hip joints was accepted as 0��. For the shoulder joint, the positioning of the arm along the side was taken as 0��.

The axis of rotation during muscle torque measurement corresponded to the axis of rotation of the torque meter. Muscle torques of the right and left limbs were measured separately, always in the order flexion-extension. Each subject was supposed to achieve the maximal power output during measurement. The force-velocity (F�Cv) and power-velocity (P�Cv) relationships Were determined on the basis of results of exercises performed on a Monark 874 E cycloergometer (Sweden) connected to a PC, using the MCE 4.0 software package (��JBA�� Zb. Staniak, Poland) (Bu?ko, 2007). After adjusting the ergometer saddle and handlebars, each subject performed the tests in a stationary position, without lifting off the saddle, with his feet strapped onto the pedals.

Each subject performed five 10-second maximal cycloergometer tests with increasing external loads amounting to 2.5, 5.0, 7.5, 10.0 and 12.5% of body weight (BW), respectively. There were 2 min rest periods between the tests. The standard procedures of exercise performance were followed, and the subjects were verbally encouraged Brefeldin_A to achieve and maintain the maximal pedaling velocity as quickly as possible. With the use of MCE, maximal power output at a given load (Pi; i �C load value) and velocity (vi) necessary to achieve Pi were determined (Bu?ko, 2007).
