Hamstring Flexibility and Peak Hamstring Muscle Strain in Sprinting, Blog by NASEinc

Abstract and Background: The effect of hamstring flexibility on the peak hamstring muscle strains in sprinting, until now, remained unknown, which limited our understanding of risk factors of hamstring muscle strain injury (hamstring injury). As a continuation of our previous study, t

Unloaded and Sled-resisted Sprinting, Blog Entry by NASEinc

Abstract: In this study, we sought to compare force-velocity relationships developed from unloaded sprinting acceleration to that compiled from multiple sled-resisted sprints. Twenty-seven mixed-code athletes performed six to seven maximal sprints, unloaded and towing a sled (20-120%

Understanding Cutting Maneuvers – The Mechanical Consequence of Preparatory Strategies and Foot Strike Pattern

Abstract and Objectives: This study investigated the relation of different previously reported preparatory strategies and musculo-skeletal loading during fast preplanned 90° cutting maneuvers (CM). The aim was to increase the understanding of the connection between whole body orientat

Vertically and Horizontally-Directed Exercises and Sprint Performance, NASEinc Blog Entry

Abstract: The capacity to rapidly generate and apply a great amount of force seems to play a key role in sprint running. However, it has recently been shown that, for sprinters, the technical ability to effectively orient the force onto the ground is more important than its total amou

Comparison of Backpedal and Cross-over Technique to Acceleration and Change of Direction Speed, Blog Entry by NASEinc

This study compared the efficiency and speed of the cross-over step to backward pedaling for defensive backs when covering a receiver. Abstract In American football, defensive backs guarding receivers use either the cross-over (CO) run or backpedal (BP) technique, but the efficacy of

Usain Bolt and Maximum Sprint Velocity, Blog Entry by NASEinc

Abstract: This study investigated the maximal sprint velocity kinematics of the fastest 100 m sprinter, Usain Bolt. Two high-speed video cameras recorded kinematics from 60 to 90 m during the men 100 m final at the IAAF World Challenge Zagreb 2011, Croatia. Despite a relatively slow r

Resistance Sled Training and Sprint Performance, Blog Entry by NASEinc

Abstract: Sprinting is key in the development and final results of competitions in a range of sport disciplines, both individual (e.g., athletics) and team sports. Resisted sled training (RST) might provide an effective training method to improve sprinting, in both the acceleration an

Conditioning Hops, Drop Jumps, and Sprint Performance, Blog Entry by NASEinc

Abstract – Background: It has previously been shown that conditioning activities consisting of repetitive hops have the potential to induce better drop jump (DJ) performance in recreationally active individuals. In the present pilot study, we investigated whether repetitive cond

June 17, 2019 NASEinc Blog: Dynamic Calf Strength and Sprint Performance

June  17, 2019 by NASE Abstract Sprinting represents a result-relevant task in many sports. The correlation of sprinting performance and one-repetition maximum (1RM) in a squat has been assumed as assured. Results of the correlation with 1RM of the plantar flexors are still
