The purpose of this study was to determine if body weight support influences the stride length-speed relationship. Additionally, the purpose was to determine if impact characteristics of running are influenced by body weight support and speed. Subjects (n=10; 6 female, 4 male) volunteered to participate in this study. All subjects were injury free and were comfortable running on a treadmill for 30 minutes. Subjects ran on a lower body positive (LBPP, Alter-G, G-Trainer) treadmill for 4 conditions of body weight (100, 40, 30 and 20% of body weight) and 4 running speeds (100, 110, 120 and 130% of the preferred speed). Subjects ran at each trial for 1 minute. Leg acceleration and stride length were recorded using an accelerometer mounted on the distal anterior-medial aspect of the tibia. Dependent variables (stride length, leg impact acceleration) were compared using 4 (speed) × 4 (body weight) repeated measures ANOVAs. It was determined that stride length was influenced by speed (p0.05). Leg impact acceleration was influenced by the interaction of speed and body weight (p
