Abstract Background: Based on recent findings regarding the mechanical determinants of sprint performance, resisted sled sprint (RSS) training may provide an effective tool for the improvement of sprint acceleration and maximal velocity. However, the volume and intensity for effective RSS training in different populations is unclear. Objectives: The primary objective was to evaluate the effectiveness of RSS …

Purpose: We transposed the concept of effectiveness of force application used in pedaling mechanics to calculate the ratio of forces (RF) during sprint running and tested the hypothesis that field sprint performance was related to the technical ability to produce high amounts of net positive horizontal force. This ability represents how effectively the total force developed …

Abstract Background: Synchronized arm and leg motion are characteristic of human running. Leg motion is an obvious gait requirement, but arm motion is not, and its functional contribution to running performance is not known. Because arm-leg coupling serves to reduce rotation about the body’s vertical axis, arm motion may be necessary to achieve the body …

Abstract Introduction: A growing body of research has focused on between-leg asymmetry as a critical factor for athletic performance and dysfunction. Specifically, various measures of between-leg asymmetry during running have been investigated in both healthy and injured populations. However, while the most important factor for running performance is the magnitude and rate of ground force application, …

Abstract: Although running shoes alter foot-ground reaction forces, particularly during impact, how they do so is incompletely understood. Here, we hypothesized that footwear effects on running ground reaction force-time patterns can be accurately predicted from the motion of two components of the body’s mass (mb): the contacting lower-limb (m1 = 0.08mb) and the remainder (m2 …

Abstract Background: A scarcity of anthropometric and kinematic data for elite United States (US) sprinters currently exists. Further analysis of how these variables correlate with sprint velocity in practice is warranted. Aim: The purpose of this investigation was to examine the relationship of anthropometric and kinematic variables and practice sprint velocity of elite sprint athletes …

Abstract: The objectives of this study were to determine the relationship between average core strength and sprint acceleration performance. Besides that, this study also intended to determine the relationship between body height and body weight with average core strength and sprint acceleration performance. Sixty-three male sport science students (height 1.67 ± 0.07 m; body mass …

ABSTRACT: The barbell hip thrust has historically been associated with the aesthetics of mainstream strength training; however in recent years due to recent studies, this exercise has started to gain respect amongst coaches and athletes looking to improve sprint performance. The purpose of this review was to investigate the relationship between the barbell hip thrust …

Abstract: Background Weightlifting training (WLT) is commonly used to improve strength, power and speed in athletes. However, to date, WLT studies have either not compared training effects against those of other training methods, or been limited by small sample sizes, which are issues that can be resolved by pooling studies in a meta-analysis. Therefore, the …
