There are many different ways that people perform pullups. In this experiment, we are analyzing two of these pullup methods to determine if there are any kinematic differences between them. The two types of pullups that we are analyzing are the overhand and the underhand. In the physical fitness tests given in schools, generally the females perform the pullup using the underhand grip, while the males use the overhand grip. This is done because the overhand pullup is thought to be too difficult for females to perform. It is thought that since the overhand pullup is more difficult to do, it is more advantageous for building muscle mass. In this experiment we will analyze several aspects of each type of pullup to see if there are any significant differences between them.
The purpose of our experiment is to compare the biomechanics of two different types of pullups (underhand grip vs. overhand grip), to analyze the advantages of each method and to determine if one type of pullup would be preferable over the other. We analyzed the two types of pullups by comparing range of motion and joint and segment velocities for various parts of the body.
