Abstract
The 180º cutting maneuver (also known as the 505 drill) is commonly seen in field and court sports, and it consists of a 15 m run up to a turning point, followed by a timed stop and 180º change of direction for 5 m. The purpose of this study was to determine the most effective joint movements, limb velocities and body positions to perform the 180º cutting maneuver. Additionally, the study compared the kinematics of the 505 drill performed indoors while wearing running shoes and outdoors while wearing cleats. For this study, twelve athletes executed the 505 drill indoors while wearing running shoes, and twelve executed the 505 drill outdoors while wearing cleats. Fifty nine independent variables were measured for each athlete and compared to the athlete’s time to complete the test. Mean test time was 2.27 seconds for the indoor group and a significantly lower 2.47 s for the outdoor group. Correlation analysis and forward stepwise multiple regression analysis was performed on both groups to determine which variables were significantly related to test time. Trunk forward lean at push off of the jab leg was most highly correlated to test time for the indoor athletes (r= -0.887), however, flexion at maximum flexion of the jab knee was most highly correlated to test time for the outdoor group (r= - 0.748). Outdoor athletes could benefit from assuming a lower and more flexed body position similar to the indoor athletes and attain a greater degree of trunk lean at jab leg touchdown.
