Abstract
Context: There are numerous ways to overload the scapular stabilizers. Objectives: To assess scapular stabilizer activity using the Bodyblade® and other traditional training devices. Design: Repeated measures analysis of surface EMG data collected from the upper trapezius (UT), lower trapezius (LT), and serratus anterior (SA) during shoulder flexion and abduction using Bodyblade® , cuff weight, and Thera-Band® resistance. Setting: Laboratory. Participants: Thirty collegiate athletes (20.0 ± 1.7 years). Intervention: Participants performed 10 repetitions of shoulder flexion and abduction. Main Outcome Measures: For each movement, normalized root mean square values (NrmsEMG) were computed for each muscle during each repetition under each training condition. Data were analyzed using 3 (condition) X 10 (repetition) repeated measures ANOVAs. Results: During shoulder flexion and abduction, the NrmsEMG of the UT, LT, and SA were signifi cantly greater when using the Bodyblade® than the Thera-Band® or cuff weight. Conclusion: The Bodyblade® produces greater scapular activity than traditional resistance techniques. © 2007 Human Kinetics, Inc.
