Objective: To investigate the muscular activation amplitudes of three regions of triceps musculature during functional activities. We hypothesized that the medial and lateral triceps would be greatest in the terminal 30° arc of extension activities.
Design: Cross sectional.
Setting: Musculoskeletal Clinical Laboratory.
Participants: 20 healthy subjects recruited from a sample of convenience.
Intervention: Fine wire electromyograhical (EMG) electrodes were placed into the medial, central, and lateral triceps to measure muscular activation amplitude and two dimensional electrogoniometric kinematic activity was recorded during functional activities associated with activities of daily living.
Main Outcome Measure(s): Root mean squared amplitudes of triceps muscles normalized …
