ABSTRACT Our aim with the present study was to determine relationships between the isokinetic variables, force and work, during the abduction-adduction movement of the shoulder articular complex. A further goal was to relate these variables between both limbs and to speeds and movements. With this in mind, and using a sample of 40 healthy young people (20 men and 20 women), all of them right-handed, a muscular evaluation was carried out by means of an electromagnetic dynamometer (Biodex), following a strict protocol for test performance. Peak torque and the total work of each limb were quantified during the abduction-adduction movement on the frontal plane. Statistical correlations were analysed and each corresponding correlation coefficient calculated. Our results reflect evident statistical correlations between isokinetic peak torque and total work. Likewise, a constant interrelationship of such variables between both limbs appeared, along with interdependence in their abductor-adductor behaviour and between speeds of 60°/s and 120°/s. Since there was a statistically significant linear relationship, the statistic r2 (determination coefficient) was also high and, as a consequence, a large percentage of the isokinetic behaviour of one variable could be explained with respect to the other.
