ABSTRACT

Evaluating the relationships between physical-test and match performance in team sports could be useful for training prescription and athlete evaluation. Here we investigated these relationships in women's Rugby Sevens. Thirty provincial-representative players performed Bronco-fitness, countermovement-jump, acceleration, speed, and strength tests within two weeks before a two-day tournament. Match-running and match-action performance measures were provided by GPS units and video analysis. Generalised and general linear mixed models were employed to estimate the effect of a two standard-deviation difference in physical-test measures on match measures. Effect magnitudes were assessed via standardisation (using the between-player SD) and, for effects on tries scored, also via match winning (based on simulating matches). Evidence for substantial and trivial true magnitudes was provided by one-sided interval-hypothesis tests and Bayesian analysis. There was good evidence of positive effects of many physical-test measures on match high-intensity running, with large effects for jump height and acceleration. There was some evidence of small-moderate positive effects of speed and Bronco, and of small-moderate negative effects of maximal strength and jump height, on match total running and high intensity changes in speed. The evidence was generally inadequate for associations between physical-test measures and match actions, but there was good evidence of small-large positive effects of back squat and jump height on tries scored. Enhancing players' jump height and back-squat performance might therefore increase the likelihood of match success in women's Rugby Sevens.

ABSTRACT

Sella, FS, McMaster, DT, Beaven, CM, Gill, ND, and Hébert-Losier, K. Match demands, anthropometric characteristics, and physical qualities of female rugby sevens athletes: A systematic review. J Strength Cond Res 33(12): 3463-3474, 2019-Since the inclusion of rugby sevens in the 2016 Olympic Games, the popularity of women's rugby sevens has grown rapidly worldwide. This systematic review aimed to summarize the scientific literature addressing the match demands, anthropometric characteristics, and physical qualities of female rugby sevens athletes and to highlight differences between competition levels and playing positions. Four electronic databases were searched, as were the reference lists and key journals. Hedges' g effect sizes with 95% confidence intervals were calculated to evaluate differences between elite and nonelite athletes, and backs and forwards. Twenty-seven studies met inclusion criteria and scored 68 ± 13% upon quality assessment. Comparisons between groups were restricted to variables where data were available. Greater running demands and intensities, number of sprints and accelerations, but lower physiological responses characterized international matches compared with nationals. At international level, backs demonstrated greater running demands and intensities, number of sprints, and physiological responses than forwards. Elite athletes were leaner, taller, and displayed superior physical qualities (e.g., maximal speed, power, upper-body strength, and aerobic capacity) compared with nonelite athletes. At elite level, forwards were heavier and displayed greater upper-body strength, whereas backs showed greater acceleration and maximal speed abilities. The specific match demands and physical requirements of female rugby sevens athletes competing at different playing levels and playing positions must be considered for developing effective training programs.

ABSTRACT

BACKGROUND: A number of key performance indicators (KPIs) have been found to discriminate between winning and losing performances in Rugby Union competitions. This study aimed to investigate the KPIs of winning and losing teams during recent Rugby Championship and Super Rugby seasons. METHODS: Data from 139 matches during the 2014-2015 Rugby Championship and 2015 Super Rugby were extracted from the SANZAAR website and retrospectively analyzed. Seventeen KPIs were used to describe the differences between winning and losing performances in different aspects of the game. Magnitude-based inferences, effect size with 90% confidence interval, percentage changes, and statistical significance were calculated. RESULTS: Winning teams during the Rugby Championship were most likely to score more tries, and very likely to gain more meters, beat more defenders, and miss less tackles compared to losing teams. In Super Rugby, winning teams were most likely to score more tries, execute more clean breaks, kicks in play and very likely to win more turnovers and concede a lower number of turnovers. The number of tackles made, and meters gained were also likely higher in Super Rugby winning teams compared to the losing counterparts. CONCLUSIONS: A limited number of KPIs differentiated were observed between winning and losing performances in the Rugby Championship, whereas numerous attacking and defensive KPIs were found to discriminate between winning and losing teams during Super Rugby. The method of data extraction, analysis and interpretation used herein could assist with game strategies and in turn better prepare teams and players for competition.
