The Effect Of Varying Weightload Intensities On Biceps Curl Technique, Jeffrey C. Gailhouse
Masters Theses
This study described biomechanical deviations from proper biceps curl technique specifically in the shoulder, trunk, body and knee angles, that occurred in response to varying intensities of an individual's 1 RM (repetition maximum). Ten college age males participated in the study. Subjects were required to perform one repetition at 60%, 70%, 80%, 90% and 100% of his 1 RM. The only differentiating factor was the order in which the five intensities were performed. Condition order was randomized to minimize bias. Movement was filmed with a high-speed motion picture camera, digitized and then analyzed with computer software.
The findings indicated that …
