Abstract

This study compared the biomechanical characteristics of the log lift and clean and jerk. Six experienced male strongman athletes performed log lifts and clean and jerks at 70% of their 1RM clean and jerk. Significant (p<0.05) between-exercise kinematic differences were observed throughout all the lifting phases, except at lift completion. The log lift demonstrated significantly greater trunk (↑24%) and hip (↑9%) range of motion than the clean and jerk. Significantly greater peak bar velocities were achieved in the clean and jerk in the second pull (16%) and the jerk (↑14%). While similarities existed in ground reaction force data between the lifts, mean and peak powers were significantly greater (↑40% to ↑64%) in propulsive phases of the clean and jerk. The log lift may be an effective conditioning stimulus to teach rapid triple extension while generating similar vertical and anterior-propulsive forces as the clean and jerk with the same given load.
