Relative age effect in male and female elite international amateur boxing.

This study aimed to determine whether the Relative Age Effect (RAE) was present in different sexes and age categories in 12 elite-level international amateur boxing competitions. A total of 4813 athletes competing between 2013 and 2022 were analysed. Athletes were split into four quartiles according to their birth date and compared to the expected (equal) birth date distribution using chi-squared goodness of fit.

Performance progression and variability in 100 m freestyle Paralympic swimmers: A comparison of medallists and para classifications.

This study quantified the performance progression and variability of elite 100 m freestyle para swimmers according to classification and medal status. To depict progression, annual world ranking times from 2009 to 2016 were obtained for 253 male and 236 female para swimmers and expressed relative to their respective (2012 & 2016) Paralympic Games performances. Comparisons according to medalling status and para classification were made using linear mixed models.

J Strength Cond Res 31(12): 3396-3402, 2017-The aim of this study was to examine the reproducibility of the internal load and performance-based responses to repeated bouts of a three-round amateur boxing simulation protocol (boxing conditioning and fitness test [BOXFIT]).

The development of a reliable amateur boxing performance analysis template.

The aim of this study was to devise a valid performance analysis system for the assessment of the movement characteristics associated with competitive amateur boxing and assess its reliability using analysts of varying experience of the sport and performance analysis. Key performance indicators to characterise the demands of an amateur contest (offensive, defensive and feinting) were developed and notated using a computerised notational analysis system. Data were subjected to intra- and inter-observer reliability assessment using median sign tests and calculating the proportion of agreement within predetermined limits of error.
