A Comparison of muscle activity in Squats vs. Leg Press Avera Sports Science A Comparison of muscle activity in Squats vs. Leg Press A high power output in the lower body is significantly correlated with sprint speed, vertical jump, agility and overall athletic performance. Hence, athletes dedicate an enormous amount of time to developing this measure. Traditionally, a primary means of training to enhance lower body power output involves performing weighed squat jumps in an upright position; however, this approach often take months to safely learn. Alternatively, weighted squat jumps may also be performed on a horizontal leg press, an approach that may be learned more quickly. To date, however, no comparisons have been made between weighted squat jumps performed in an upright and reclined position to determine the differences in muscle activity patterns and forces generated during these exercises. Therefore, the aim of this project is to examine the muscle activity and force generating characteristics of these two exercises. A secondary aim involves comparing these outcomes to the same measures captured during a vertical jump. There is no cost to you to participate in this study. The criteria for participating in this research project includes being 18-35 years of age and currently not experiencing any lower musculoskeletal issues such as knee or back pain. We seek individuals who routinely strength train, and who are excited at the prospect of participating in an investigation that helps clarify the optimum approach to developing lower body power For more information, please call or email: Derek Ferley, PhD, CSCS 605-322-5183 derek.ferley@avera.org
