Comparison of Weightlifting, Traditional Resistance Training and Plyometrics on Strength, Power and Speed 

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 …

Occurrences of Near-to-Maximum Speed-Running Bouts in Elite Soccer

ABSTRACT – Aim: To quantify the occurrence of near-to-maximal speed-running bouts in elite soccer players. Methods: Tracking match data from 35 professional players (23 ± 3 yrs) were analysed over four seasons (2015–2019). The number of runs reaching >80, >85 and >90% of players’ individual maximal sprinting speed (MSS) was computed. Differences in peak speed …

Thigh Angular Acceleration During Running Performance

ABSTRACT: The hip joint and surrounding musculature must generate and withstand torque during the swing phase of running. Prior research has demonstrated that sagittal plane hip torque increases with speed, indicating that thigh angular acceleration likely increases in a similar manner and may be an important gait parameter. In this investigation, we modelled thigh angle …

Are Females Closer to Males in Shorter Sprint Races?

Abstract: The body size and composition differences between men and women are set by genetic factors with relatively constant offsets, particularly in homogeneous athletic populations. However, performance differences between the sexes appear to be more variable, potentially due to the mechanical demands of different events. Here, we set out to analyze the sex performance differences …

Muscle Elasticity of the Medial Gastrocnemius and Sprint Performance

Abstract / Purpose: Limited information is available on the association between muscle material properties and sprint performance. We aimed to identify whether and how the elasticity of passive and active muscle of the medial gastrocnemius (MG) is related to sprint performance.Methods: MG shear wave speed was measured under passive and active (20%, 50%, 80% of maximal voluntary …

Specificity of Strength Exercises to Improve Acceleration

Abstract: The purpose of the study was to use musculoskeletal modelling to examine the specificity of bounding and loaded countermovement jumps (CMJ) to sprinting acceleration. Ten male participants performed 10 m sprints, continuous bounding, and loaded CMJs. A generic OpenSim model was scaled to each individual and used to calculate joint moments, angles and angular …

Active and Passive Recovery following High-intensity Interval Exercise

Abstract Introduction: It has been suggested that recovery mode may contribute to performance during high-intensity interval exercise. However, there is no consensus regarding the effects of active and passive recovery modes on subsequent performance. The aim of this study was to compare the effect of active versus passive recovery on performance during repeated high-intensity interval exercise. …

Gluteus and Posterior Thigh Muscle Sizes in Sprinters

ABSTRACT: Muscle hypertrophy can occur non-uniformly in athletes who repetitively perform particular movements, presumably leading to a unique muscle size distribution along the length. The present study aimed to examine if sprinters have unique size distributions within the gluteus and posterior thigh muscles. Nineteen male sprinters and 20 untrained males participated in the present study. …
