ABSTRACT: DURING LANDING, THE BODY IS EXPOSED TO HIGH GROUND REACTION FORCES (GRFs), CONTRIBUTING TO LOWER-BODY INJURY OCCURRENCE. DROP HEIGHT, JUMPING DISTANCE, LANDING STRATEGY, AND SPECIFIC LANDING KINEMATICS HAVE BEEN IDENTIFIED AS FACTORS THAT HAVE A SIGNIFICANT INFLUENCE ON LANDING GRF. EFFECTIVE LANDING PROGRESSIONS INCLUDE INCREASING JUMP HEIGHT AND DISTANCE, LANDING BILATERAL TO UNILATERAL, FOREFOOT TO HEEL FOOT PLACEMENT, ENLARGING KNEE ANGLE ON IMPACT, AND REDUCING PASS HEIGHT. IN ADDITION, IMPLEMENTING FUNDAMENTAL LANDING PRINCIPLES ALLOWS THE BODY TO DISSIPATE GRF SAFELY AND EFFICIENTLY. THEREFORE, THE INCORPORATION OF THESE FACTORS INTO GENERAL CONDITIONING PRACTICE TO PROGRESS LANDING INTENSITY IS RECOMMENDED.
