A influência da envergadura na carga máxima do supino reto

Abstract

With the increasing of weight- lifiting popularization, some of the sciences that studies this area increased its scientific production, being one of then, the biomechanic. The following study objective is to verify if there is influence of the wingspan on the maximal load of the bench press. Twelve male volunteers, divided into groups "A" and "B", participated in the study, the first group being all individuals with more than 180 cm of wingspan and the second, all with less than 170 cm. The 1RM test was performed to determine the maximum load lifted by the volunteers in a single repetition, and the body mass index (BMI) to verify body property of all individuals. The results showed that maximum span and maximal load have a strong negative correlation in group "A" (r= -0.82) and that span has strong positive correlation (r> 0.7) with range of motion and lever arm in both groups. It can thus conclude that individuals with larger wingspan tend to lift less load than individuals with smaller wingspan and that this occurs because smaller individuals also have smaller range of motion and lever arm when performing the bench press exercise, thus making exercise easier for this type of person.
