How to Compare Relative Age Effect in Different Sports? A New Methodological Approach-Example of Youth Olympic Games.

This research aimed to propose a new methodological approach for analyzing relative age effect (RAE) in different sports or samples named "Relative age effect overall scale" (RAEOS). The sample consisted of 1455 male and female young athletes who competed in four different sports (basketball, = 159; handball, = 215; swimming, = 981; taekwondo, = 100) at the Youth Olympic Games (YOG) in Buenos Aires in 2018. To construct the new model, the sample was classified into four unified quartiles of a specific range depending on the sport (swimming: 48-month range, taekwondo: 24-month range, and basketball and handball: 36-month range).

Height-based model for the categorization of athletes in combat sports.

Reducing bodyweight within a short-time participating in kicking combat sports can adversely affect health. This study's aim creating an improved model to categorize athletes in kicking combat sports. The investigation focused on 795 athletes (11-24 years), participating in the Croatian National Taekwondo Championship.

Explosive Push-ups: From Popular Simple Exercises to Valid Tests for Upper-Body Power.

Zalleg, D, Ben Dhahbi, A, Dhahbi, W, Sellami, M, Padulo, J, Souaifi, M, Bešlija, T, and Chamari, K. Explosive push-ups: From popular simple exercises to valid tests for upper-body power. J Strength Cond Res 34(10): 2877-2885, 2020-The purpose of this study was to assess the logical and ecological validity of 5 explosive push-up variations as a means of upper-body power assessment, using the factorial characterization of ground reaction force-based (GRF-based) parameter outputs.

Barbell Hip-Thrust Exercise: Test-Retest Reliability and Correlation With Isokinetic Performance.

Dello Iacono, A, Padulo, J, Bešlija, T, and Halperin, I. Barbell hip-thrust exercise: Test-retest reliability and correlation with isokinetic performance. J Strength Cond Res 35(3): 659-667, 2021-The barbell hip-thrust (BHT) exercise is growing in popularity as evident by the large increase in research outputs investigating its utility as a training intervention and a testing tool.

Reliability, Sensitivity, and Minimal Detectable Change of a New Specific Climbing Test for Assessing Asymmetry in Reach Technique.

Reliability, sensitivity, and minimal detectable change of a new specific climbing test for assessing asymmetry in reach technique. J Strength Cond Res 35(2): 527-534, 2021-The aims of this study were to establish intertrial and intersession reliability, sensitivity, and minimal detectable change of a new climbing test specifically for assessing asymmetry in reach technique (TEST).

Validity and Reliability of the 30-s Continuous Jump for Anaerobic Power and Capacity Assessment in Combat Sport.

Cycling test such Wingate anaerobic test (WAnT) is used to measure anaerobic power (AP), but not anaerobic capacity (AC, i.e., the metabolic energy demand).
