H2No – Why Drinking Water All Day Long Is Not the Best Way to Stay Hydrated BY MARKHAM HEID, NASEinc Blog

Dehydration is a drag on human performance. It can cause fatigue and sap endurance among athletes, according to a 2018 study in the journal Frontiers in Physiology. Even mild dehydration can interfere with a person’s mood or ability to concentrate. Water is cheap and healthy. And drin

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

Kinetic Demands of Sprinting Shift Across the Acceleration Phase: Novel Analysis of Entire Force Waveforms , Blog entry by NASEinc

Abstract: A novel approach of analyzing complete ground reaction force waveforms rather than discrete kinetic variables can provide new insight to sprint biomechanics. This study aimed to understand how these waveforms are associated with better performance across entire sprint accele

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)
