This study compared the biomechanical characteristics of the heavy sprintstyle sled pull and squat. Six experienced male strongman athletes performed sled pulls and squats at 70% of their 1RM squat. Significant kinematic and kinetic differences were observed between the sled pull start and squat at the start of the concentric phase and at maximum knee extension. The first stride of the heavy sled pull demonstrated significantly (p<0.05) lower stride lengths and average velocities and a higher mean ratio of force than the stride at 2-3 m. The force orientation and magnitude associated with the heavy sprint-style sled pull demonstrates that the heavy sled pull may be an effective conditioning stimulus to generate superior anterior-propulsive forces compared to vertically orientated exercises such as the squat with the same given load. Such adaptations may be beneficial in sports where higher levels of sprint momentum are needed to make and break tackles.
