Rugby is a demanding contact sport. In light of research, poor balance, reduced jumping ability, muscle strength, and incorrect landing patterns might contribute to the increased risk of injury in athletes. Investigating the relationship between tests assessing these abilities might not only allow for the skillful programming of preventive training but also helps in assessing the risk of injury to athletes. Thus, the main purpose of this study was to investigate the relationship between dynamic balance, vertical and horizontal jumps, and jump-landings movement patterns. Thirty-one healthy amateur adolescent rugby players (age: 14.3 ± 1.6 years, height 171.4 ± 9.7 cm, body mass 80 ± 26 kg) participated in the study. Data were collected by the Y-balance Test (YBT), Counter Movement Jump (CMJ), Single Leg Hop for Distance (SLHD), and Landing Error Score System (LESS). Significant positive correlations were found between SLHD both legs (SLHDb) and YBT Composite both legs (COMb) (r = 0.51, p = 0.0037) and between SLHDb and CMJ (r = 0.72, p < 0.0001). A relationship was also observed between the CMJ and YBT COMb test (r = 0.51, p = 0.006). Moderate positive correlations were found between the dominant legs in SLHD and the posterolateral (r = 0.40, p = 0.027), posteromedial (r = 0.43, p = 0.014), and composite (r = 0.48, p = 0.006) directions of the YBT. These results indicate that variables that are dependent on each other can support in the assessment of injury-risk and in enhancing sports performance of young athletes.

The purpose of this study was to examine the relationship between scores on the attentional subscales of Nideffer's Test of Attentional and Interpersonal Style (TAIS) and playing standard, age, and position played within the sport of rugby. 144 male volunteer rugby players from the Vancouver Island Rugby Union were tested. The sample included 72 above average rugby players and 72 of average playing standard who were further classified by age: 24 under 19 yr. (U.19), 24 under 23 yr. (U.23), and 24 senior. Four specific positional groups were identified within the sample: Tight Five ( n = 56), Backrow ( n = 24), Halfbacks ( n = 20), and Outside Backs ( n = 44). A series of two-way multivariate analyses of variance gave no significant differences between the two different playing standards except for age. The senior group differed from both the U.19 and U.23 groups on narrowing. In addition, significant differences were also observed between the Halfbacks and the remaining positional groups (Tight Five, Backrow, and Threequarters) on two of the six measures, they demonstrated greater broad-external focus and less internal overload. It was concluded that the Halfbacks, who are the decision makers within the team, reflected most closely Nideffer's concept of an effective attentional style and the attentional subscales did discriminate minimally between rugby players of different ages and playing position.

Sprint Ability

Repeated sprint ability (RSA) is typically used for speed-endurance and agility-endurance training and assessment. RSA is preferred as it mimics actual performance during competition. RSA test involves straight sprint and quick turning movements. Thus, the aim of this study is to determine the relationship between height and body weight measurements on RSA performance, as height and weight may influence the mechanical properties of it. Ten male rugby players (body weight 72.99 ± 14.29 kg, height 169 ± 5.55 cm) selected for Perak SUKMA 2018 team were assessed during centralized training ~9 months prior to their competition.  Body weight and height were measured using standard laboratory weight and height scales prior to the RSA test. RSA were hand-timed for 5 repetitions x 2 sets x 60 seconds rest in between repetitions x 5 minutes rest in-between set. The sprints were performed in the evenings, on grass surface with participants wearing full playing attire. Standardized pre-game warm-up and cooling down were performed. Data recorded was analyzed statistically using a t-test comparison for set one versus set two performances. Pearson correlation coefficient was used to analyze the relationship between anthropometric measures and the RSA test. RSA performance has a negative correlation with the athletes’ height (r= -0.233 set 1, r = -0.435 set 2) and body weight (r= -0.556 set 1, r= -0.629 set 2). RSA performance was significantly different between set 1 and set 2 (p=0.001), with set 1 performance better than set 2. Body height and body weight did not influence RSA performance. Athletes involved did not have adequate speed-agility-endurance needed. In practical, selecting athletes based on their body height and body weight with the assumption that taller and heavier athletes may perform better may not be suitable for this kind of sport. On the other hand, using RSA to test and develop the speed-agility-endurance ability for rugby players is suggested.

The evaluation of change-of-direction (COD) performance is strongly focused on the time spent to perform the test trials, while much less is known about the technical execution adopted during the COD movements. Thus, the purposes of this study were to evaluate (1) the relationship between straight- and COD-sprint tests and (2) the technical execution of COD movements in relation to different age categories of young rugby players. Young rugby players (N = 157, age range 8–19 y) completed a test battery composed of a 15-m straight-sprint test (15SS) and a 15-m sprint test performed with 2 changes of direction (15COD). Significant differences were detected between age categories for both tests. Significant correlations were found between 15SS and 15COD. The analysis of the technical execution of the 15COD test showed differences between age categories, with a prevalence of rounded turns up to the U15 category. These findings confirmed the relationship between straight and COD abilities in young male rugby players. Moreover, the new approach introduced by this study, based on the analysis of COD technical execution, revealed that this performance could be conditioned by the age and mastery level of the players.

The aim of this study is to consider the hypothesis that wearing mouthguards (MGs) from a young age helps to shape players’ habit of continuing to wear MGs as adults. In addition, we consider the mandatory rule of wearing mouthguards in the youth category on the future wearing rates of mouthguards. Eighty-five Japanese male amateur rugby players were included in this study. We examined the relationship between the wearing rates of mouthguards when participants were high school students and as adults (in 2018) using a questionnaire. Collected data were classified into categories (age, mouthguard type, and applied mandatory rule or not), and their relationships were analyzed. The wearing rate of mouthguards in high school was significantly related to the wearing rate of mouthguards in adulthood (χ2 = 12.1, p < 0.01). The mandatory rule to wear mouthguards at high school was related to the wearing rates of mouthguards as adults, but not significantly (χ2 = 3.42, p = 0.06). Participants’ mouthguard wearing rates as adults were affected by their high school wearing rates. The mandatory rule of wearing mouthguards in the youth category may be somewhat effective for improving mouthguard wearing rates; however, it is more important to provide knowledge about their importance.
