Replication study: Investigating the effects of maximal anaerobic fatigue on dynamic postural control using the Y-Balance Test.

Objectives: The aim of this study was to replicate the study titled "Investigating the effects of maximal anaerobic fatigue on dynamic postural control using the Y-Balance Test" by Johnston et al. (2018) as part of a large replication project. This study aimed to determine the effects of maximal anaerobic fatigue on dynamic postural control using the Y-Balance Test, with a specific focus on anterior reach distance.

Publication bias, statistical power and reporting practices in the Journal of Sports Sciences: potential barriers to replicability.

Two factors that decrease the replicability of studies in the scientific literature are publication bias and studies with underpowered desgins. One way to ensure that studies have adequate statistical power to detect the effect size of interest is by conducting a-priori power analyses. Yet, a previous editorial published in the reported a median sample size of 19 and the scarce usage of a-priori power analyses.

Replication concerns in sports and exercise science: a narrative review of selected methodological issues in the field.

Known methodological issues such as publication bias, questionable research practices and studies with underpowered designs are known to decrease the replicability of study findings. The presence of such issues has been widely established across different research fields, especially in psychology. Their presence raised the first concerns that the replicability of study findings could be low and led researchers to conduct large replication projects.

Proposal of a Selection Protocol for Replication of Studies in Sports and Exercise Science.

Introduction: To improve the rigor of science, experimental evidence for scientific claims ideally needs to be replicated repeatedly with comparable analyses and new data to increase the collective confidence in the veracity of those claims. Large replication projects in psychology and cancer biology have evaluated the replicability of their fields but no collaborative effort has been undertaken in sports and exercise science. We propose to undertake such an effort here.

The effects of footwear on dynamic stability and impact loading in jump landing.

Research into the effect of footwear on dynamic stability and impact loading is still in its infancy. The aim of this study was to determine whether cushioned footwear influenced dynamic stability (dynamic postural stability index (DPSI) and time to stabilisation (TTS)) or impact loading (peak ground reaction force (pGRF) and loading rate (LR)) through a series of single-leg jump landings when compared to barefoot and minimalist shoes. Fourteen healthy, active participants (9 males, 5 females, Age: 21 ± 1 years; height: 174 ± 9.

Electric Muscle Stimulation (EMS) Does Not Improve Anaerobic Performance Measures During a Repeated Wingate Test.

: The aim of this study was to examine differences between a control warm-up and an Electric Muscle Stimulation (EMS)-induced warm-up in off-road cyclists when examining anaerobic performance measures from a repeated Wingate test (WAnT). : Twelve trained off-road cyclists completed a randomized crossover study (age: 31 ± 10 years, height: 176.79 ± 6.

Training and technique choices predict self-reported running injuries: An international study.

Objectives: The aim of this study was to describe the self-reported injury, training, and running technique choices of regular runners in four international regions.

Design And Setting: 756 participants began an expert derived self-report online survey in Ireland, USA, Hong Kong and Australia.

Participants: 325 participants completed the survey (age = 38 ± 10 years; weight = 68.

Small Step Frequency Changes Due to Footwear Condition Have No Effect on Running Economy.

The aim of this study is to examine if small increases to step frequency associated with minimal footwear can influence Running Economy (RE). Twelve club-level runners with eight weeks of minimal footwear experience were recruited (age, 41±9 years; stature, 177.2±10.

Transitioning to Minimal Footwear: a Systematic Review of Methods and Future Clinical Recommendations.

Background: Recent interest in barefoot running has led to the development of minimalist running shoes that are popular in distance runners. A careful transition to these shoes has been suggested and examined in the literature. However, no guidelines based on systematic evidence have been presented.

Kinetic changes during a six-week minimal footwear and gait-retraining intervention in runners.

An evaluation of a six-week Combined minimal footwear transition and gait-retraining combination vs. gait retraining only on impact characteristics and leg stiffness. Twenty-four trained male runners were randomly assigned to either (1) Minimalist footwear transition Combined with gait-retraining over a six-week period ("Combined" group; n = 12) examined in both footwear, or (2) a gait-retraining group only with no minimalist footwear exposure ("Control"; n = 12).

Eight weeks gait retraining in minimalist footwear has no effect on running economy.

Purpose: To evaluate the effects of an eight week combined minimalist footwear (MFW) and gait-retraining intervention on running economy (RE) and kinematics in conventional footwear runners.

Methods: Twenty-three trained male runners (age: 43 ± 10 years, stature: 177.2 ± 9.
