Abstract
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 a relationship existed between resistance and the magnitude of movement in the selected angles. As resistance increased, angular movement correspondingly increased.
It was concluded that training at intensities less than 90% of an individual's 1 RM was more conducive to proper technique and would still allow for optimal strength gains.
