An Upper Extremity Biomechanical Model: Application To The Bicep Curl, Adam Miller Apr 2007

An Upper Extremity Biomechanical Model: Application To The Bicep Curl, Adam Miller

Masters Theses

An upper extremity biomechanical model was developed based on recommendations provided by the International Society of Biomechanics. The model was used to investigate biomechanical differences between two variations of the bicep curl exercise: the standing and incline dumbbell curls. An 8-camera Vicon motion capture system was used to collect data on five subjects that executed 10 repetitions of each type of curl.

Four key biomechanical indicator variables were investigated: range of motion, maximum elbow flexion moment, mean elbow flexion moment, and the flexion angle at which the maximum flexion moment occurs. On average, the range of motion at the elbow …
