Rugby is a game in which the rules are regularly evaluated and changed to make the game more attractive, safer, and faster for spectators. This affects the requirements of the game and the profile depending on the position of the game. Objective.The purpose of this work is to analyze and prove that in the game of rugby 7 there are no major differences between the two compartments depending on the motor capacity. Material and method. In the present work, 14 players were investigated, performance sportswomen from the rugby team in7 women's C.S. Politehnica Iasi. The tests applied were:speed over the distance of 10 m and 50 m, CMJ, agility test 505 and VamEval. The statistical analysis was done using the SPSS Statistics 23 program. Results. The results of the tests proved that thephysical profile of the athletes is homogeneous, there are no significant differences between the compartments. Conclusions.The results of this study show that a good athlete is a good rugby player in seven. Polyvalence is an advantage of rugby players in 7 because it gives them the opportunity to quickly move from the position of forward to that of a player of backwards and vice versa

Lower Body Power

AbstractThis study investigated relationships between lower-body power, measured by a vertical jump (VJ) and standing broad jump (SBJ), with multidirectional speed in collegiate female rugby players. The rugby player data was compared to that of general team sport athletes to ascertain whether there were characteristics specific to collegiate rugby players. Multi-directional speed was measured by a 20-meter (m) sprint (0-5, 0-10, 0-20 m intervals) and 505 change-of-direction speed test. Eight rugby players and eight team sport athletes completed all tests. Spearman’s correlations calculated relationships between the VJ and SBJ with the speed tests, and stepwise multiple regressions determined whether the jump tests predicted speed performance (p≤ 0.05). For the rugby players, the VJ correlated with the 0-20 m interval (r = −0.73). The SBJ correlated with the 0-5 and 0-10 m intervals, and the left-leg 505 (r = −0.71 to −0.88), and predicted 0-5 m and left-leg 505 time (r2= 0.50-0.58). For the team sport athletes, only the VJ correlated with left-leg 505 (r = −0.80), and predicted left- and right-leg 505 times (r2= 0.61-0.69). The results suggest that horizontal power measured by a SBJ has a greater contribution to multidirectional speed in collegiate female rugby players.

<p>This thesis examines the cultural and social significance of women’s rugby. It attempts to make sense of the experience of the everyday women rugby player at a grass roots level and is an area that has received limited attention in sociology. The purpose of this thesis was to document, explore and reflect upon personal stories and experiences of women rugby players by using qualitative research methods. The participants in the research were 12 women rugby players from different rugby clubs. They were arranged in small focus groups that ran over a period of four weeks where personal stories and experiences were shared and critical reflection of the narratives took place. Common themes identified throughout the research process included the current structure and organisation of women’s rugby that still results in women’s rugby being less valued on and off the field. The stories and experiences revealed the fine line that woman rugby players tread as they try to manage the tension of playing to the ideal image of a rugby player on the field and maintaining their femininity after the game. The findings suggest that the pleasures of rugby found in physicality, roughness, drinking, and associated with masculine culture, are equally pleasurable for these women rugby players. These findings provided insights into the lived experiences of the everyday women’s rugby player at a grass root level. They also suggest that the various experiences of women rugby players, both positive and negative, need to be recognised so that women can be better valued as rugby players rather than as women who just play rugby.</p>

A key to success in many sports stems from the ability to anticipate what a player is going to do next. In sporting duels such as a 1 vs. 1 in rugby, the attacker can try and beat the defender by using deceptive movement. Those strategies involve an evolution of the centre of mass (COM) in the medio-lateral plane, from a minimal state to maximal displacement just before the final reorientation. The aim of this work is to consider this displacement as a motion-gap, as outlined in Tau theory, as a potential variable that may specify deceptive movement and as a means of comparing anticipatory performance between mid-level players and novices in rugby. Using a virtual reality set-up, 8 mid-level rugby players (ML) and 8 novices (NOV) observed deceptive (DM) and non-deceptive movements (NDM). The global framework used an occlusion time paradigm with four occlusion times. Participants had to judge the final direction of the attacker after the different cuts-off. For each movement and at each occlusion time, we coupled the ability to predict the good final direction with the value of the COM displacement in the medio-lateral (COM M/L) plane or with the Tau of this parameter (Tau COM). Firstly, results show that the Tau COM is a more predictive optical variable than the simple COM M/L. Secondly, this optical variable Tau COM is used by both groups, and finally, with a specific methodology we showed that mid-level players have significantly better anticipatory ability than the novice group.

If we make a set of measurements, such as narrow-band or multicolour photo-electric measurements, which are designed to improve a scheme of classification, and in particular if they are designed to extend the number of dimensions of classification, i.e. the number of classification parameters, then some important problems of analytical procedure arise. First, it is important not to reproduce the errors of the classification scheme which we are trying to improve. Second, when trying to extend the number of dimensions of classification we have little or nothing with which to test the validity of the new parameters.Problems similar to these have occurred in other areas of scientific research (notably psychology and education) and the branch of Statistics called Multivariate Analysis has been developed to deal with them. The techniques of this subject are largely unknown to astronomers, but, if carefully applied, they should at the very least ensure that the astronomer gets the maximum amount of information out of his data and does not waste his time looking for information which is not there. More optimistically, these techniques are potentially capable of indicating the number of classification parameters necessary and giving specific formulas for computing them, as well as pinpointing those particular measurements which are most crucial for determining the classification parameters.

Spectrum Imaging

As interest for parallel EELS spectrum imaging grows in laboratories equipped with commercial spectrometers, different approaches were used in recent years by a few research groups in the development of the technique of spectrum imaging as reported in the literature. Either by controlling, with a personal computer both the microsope and the spectrometer or using more powerful workstations interfaced to conventional multichannel analysers with commercially available programs to control the microscope and the spectrometer, spectrum images can now be obtained. Work on the limits of the technique, in terms of the quantitative performance was reported, however, by the present author where a systematic study of artifacts detection limits, statistical errors as a function of desired spatial resolution and range of chemical elements to be studied in a map was carried out The aim of the present paper is to show an application of quantitative parallel EELS spectrum imaging where statistical analysis is performed at each pixel and interpretation is carried out using criteria established from the statistical analysis and variations in composition are analyzed with the help of information retreived from t/γ maps so that artifacts are avoided.
