Backward Sprinting and Sports Performance, Blog Entry by NASEinc

Abstract: Backward running (BR) is a form of locomotion that occurs in short bursts during many overground field and court sports. It has also traditionally been used in clinical settings as a method to rehabilitate lower body injuries. Comparisons between BR and forward running (FR) have led to the discovery that both may be generated …

Ground Reaction Forces During a Drop Vertical Jump: Impact of External Load Training, Blog Entry by NASEinc

This study provides new information concerning specific training exercises that elicit a higher vertically-directed ground reaction force (GRF); a key factor in determining maximum mph speed. Abstract External load training (ELT) is a supplemental training method used to potentially improve high intensity task performance. However, biomechanical parameters such as ground reaction forces (GRF), ground contact …

Kinetic Determinants of Reactive Strength in Highly Trained Sprint Athletes, Blog Entry by NASEinc

Abstract: The purpose of this study was to determine the braking and propulsive phase kinetic variables underpinning reactive strength in highly trained sprint athletes in comparison with a nonsprint-trained control group. Twelve highly trained sprint athletes and 12 nonsprint–trained participants performed drop jumps (DJs) from 0.25, 0.50, and 0.75 m onto a force plate. One …

Towing at Supra-maximal Speed and Form and Technique by NASEinc

The amount of force utilized during supra-maximal towing with surgical tubing and other devices determines training effectiveness. A force that causes athletes to break form is too much. Force that does not result in faster stride rates and shorter ground contact time is too little. The study below examines these and other factors to provide …
