Abstract

INTRODUCTION. This exploratory investigation examines the biomechanical correlations underlying axe throwing accuracy among amateur throwers, due to the fact that there is limited literature on upper extremity kinematics across wrist, elbow, and shoulder velocities affecting the handle, angle, and distance accuracy of the axe during time of release. PURPOSE. The purpose was to systematically examine the biomechanical factors influencing throwing precision across athletic populations, utilizing research methodologies to map the intricate relationships between kinematic variables and performance accuracy. METHODS. Utilizing Awinda inertial measurement units, researchers analyzed upper extremity kinematics across wrist, elbow, and shoulder velocities during twelve trials involving four collegiate competitive axe throwers. For the target, we used four pieces of plywood, about 8’ feet tall, with a line going horizontally in the middle of the wood to determine the target point for each throw. Variables used were distance to the bullseye, angle of axe on the target, and angle of handle on the target. RESULTS. Pearson’s correlation analysis revealed nuanced relationships between velocity parameters and throwing precision. For each test of the elbow, the correlations are as followed: distance/level: 0.17; axe angle/velocity: -0.03; handle/velocity: 0.54. For each test of the shoulder, the correlations are as followed: distance/velocity: 0.28; axe angle/velocity: -0.23; handle/velocity: 0.95. CONCLUSION. Shoulder velocity exhibited more substantive correlations with target distance and axe trajectory compared to elbow velocity measurements. Notably, most kinematic correlations were moderate. The research underscores the complexity of athletic motor performance, highlighting the necessity for expanded studies to comprehensively map the intricate relationship between biomechanical parameters and throwing precision.
