Abstract

During the positive work phase of pull-ups, integrated electromyographic signals (EMGs) were obtained from selected muscles of the upper chest, shoulder,upper beck, and arm in one male and one female subjects of comparable age, height, and body mass. In addition, displacement of body mass as well were calculated as were force and power. Forward as well as reverse grasps on the horizontal bar were additional variables. Irrespective of bargrasp, the data failed to show sex differences in the electromyographic and biomechanical aspects of pull-up performance, assuming of course applied forde and power and therefore number of completions of pull-ups of the freehanging body were expressed as a function of mass being displaced. Pull-ups research represents a complex and challenging study having many fundamental ramifications, but the methodology we have presented has the integrity and capacity to be utilized in the scrutiny and expansion of pull-ups studies.
