The purpose of this study was to evaluate the energy, macronutrient an selected micronutrient intake of second league Rugby Union players and to assess the anthropometric characteristic of this group. Players (n = 44) were divided into forwards (n = 20) and backs (n = 24), who differed significantly in weight (92.6 vs 80.8 kg), BMI (28.6 vs 24.5 kg/m2) and percentage of body fat (22.0 vs 13.3%). The dietary intake was assessed using 3-day dietary recalls. There were no significant differences in dietary intake related to player position. Athletes reported a mean daily energy intake of 3613.4 ±942.6 kcal (carbohydrates 41.4%, protein 17.8%, fats 39.3%). The mean intake of carbohydrates and protein were on a level of 4.8 and 1.9 g/kg of body weight/day, respectively. Although the mean daily intake of minerals and vitamins met recommendations, some players did not reach the requirements, especially for potassium (61.4%) and vitamin C (22.7%). The differences in body compositions of the players suggest differences in the type of training and the specificity of the player’s position. These improper proportions of dietary nutrients within the study group may decrease opportunities to achieve optimum results during matches.

This study aimed to compare the physical demands of contact small sided game (CSSG), non-contact small sided game (NCSSG) and match play in female rugby union. Fifteen female rugby union players participated within this study. Participants completed two testing sessions. Session one involved two 20-minute small sided games (contact and non-contact). Session two involved a competitive rugby union game. Movement characteristics, heart rate, PlayerLoadTM and tackles were recorded using GPS units and heart rate monitors. No significant differences were identified between conditions in relation to average heart rate or time spent in different heart rate zones. Significant differences were identified between conditions for distance, normalised PlayerLoadTM and tackles. Distance covered was significantly higher in the non-contact small sided game, while normalised PlayerLoadTM and tackles were significantly lower in this condition. These findings suggest that the physiological stress, in terms of heart rate, is comparable between the match and both small sided games. Thus both small sided games seem to elicit an appropriate internal training response. However, the reductions in tackles and normalised PlayerLoadTM in the non-contact small sided game are likely to reduce injury risk, while the increase in distance covered may enhance the training stimuli provided in this condition.
