Purpose:This study examined the body composition, nutritional knowledge, behaviors, attitudes, and educational needs of senior schoolboy rugby players in Ireland.Methods:Participants included 203 male rugby players age 15–18 yr competing at Senior School’s Cup level in Leinster, Ireland. Estimation of body composition included measurement of height, weight, and percentage body fat (PBF; using bioelectrical impedance analysis, Tanita BC-418). Nutritional knowledge, behaviors, attitudes, and education needs were assessed by questionnaire.Results:The range of PBF was 5.1–25.3%. Sixty-eight percent of the players in this study had a healthy PBF (10–20%), 32 (22%) were classified as underweight (<10% body fat), and 9.7% (n = 14) were overweight. Assessment of nutritional knowledge demonstrated poor knowledge of the foods required for refueling, appropriate use of sports drinks, and the role of protein in muscle formation. Alcohol consumption and dietary supplement use were reported by 87.7% and 64.5%, respectively. A perception that greater body size enhances sport performance did not predict dietary supplement use. Nutritional advice had been previously sought by 121 players from coaches (66.9%), magazines (42.1%), Web sites (38.8%), peers (35.5%), family (28.1%), sport organizations (16.5%), and health professionals (8.2%). Nutritional knowledge was no better in these players, nor did better nutritional knowledge correlate with positive dietary behaviors or attitudes.Conclusions:Most players had a healthy PBF. Despite a positive attitude toward nutrition, poor nutritional knowledge and dietary practices were observed in many players. Young athletes’ nutritional knowledge and dietary practices may benefit from appropriate nutritional education.

Objective. The aim of this study was to describe the body composition, strength and speed characteristics of elite junior South African rugby players. Design. Cross-sectional. Setting. Field study. Subjects. Rugby players (16 and 18 years old, N = 174) selected for the South African Rugby Union National Green Squad. Outcome measures. Body composition, 10 m and 40 m speed, agility, 1RM bench press, underhand pull-ups, push-ups, multistage shuttle run. Results. The under-16 players were on average shorter (175.6 ± 5.7 v. 179.2 ± 6.7 cm), weighed less (76.5 ± 8.2 v. 84.8 ± 8.3 kg) had less upper body absolute strength (77.1 ± 11.8 kg v. 95.3 ± 16.7 kg) and muscular endurance (41 ± 12 v. 52 ± 15 push-ups) and aerobic fitness (87.1 ± 19.4 v. 93.5 ± 15.3 shuttles) than the under-18 players. There were no differences in body fat, sprinting speed (10 m and 40 m) or agility between the two age groups. There were differences between playing positions, with the props having the most body fat, strongest upper bodies, slowest sprinting speed, least agility and lowest aerobic capacity compared with players in the other positions. Conclusion. This study provides data for elite junior rugby players and can be used to monitor the progression of players after intervention while also assisting with talent identification for the different playing positions.

Dietary Supplement Use

The use of dietary supplements is prevalent among many groups worldwide. However, few studies have examined their use among government employees. The aim of this cross-sectional study was to determine the association among sociodemographic characteristics, body weight status, and energy intake with dietary supplement use among government employees in Putrajaya, Malaysia. Simple random sampling was used to select a sample of 460 government employees from six ministries in Putrajaya, Malaysia. The data used in this study were collected through anthropometric measurements (height, weight, % body fat, waist and hip circumferences), a self-administered questionnaire (sociodemographic characteristics and dietary supplements use), and an interviewer-administered questionnaire (24-hour dietary recall; fruit and vegetable intake). The results indicated that the prevalence of dietary supplement use was 55.4%, with vitamin C (38.4%) being the most popular type of dietary supplement. Health issues (80.8%) were the most common reason for usage, internet (59.2%) was the main source of information, and pharmacies (71.8%) were the most indicated places to purchase dietary supplements. A multivariate analysis showed that participants who were female, married, had better monthly income, lived within a smaller household size, had a normal body mass index, classified as having unhealthily high body fat percentage, did not skip breakfast, and consumed at least five servings of fruits and vegetables per day were significantly more likely to use dietary supplements. In conclusion, health-conscious groups were more prone to consume dietary supplements, and due to the high prevalence of dietary supplement use, dissemination of accurate scientific information regarding dietary supplements is highly recommended among government employees.

Abstract Background: The physical exertion in the game of rugby is intense and depends on the playing position. This study hypothesized that peculiarities of body composition are important and should be properly interpreted in order to improve fitness and particularly in order to reduce the risk of injuries. Purpose: The aim of the present paper is to highlight the importance of body composition evaluation and to underline the usefulness of the data thus obtained for both training individualization and sports injuries risk reduction. Material and Methods: Thirty seven senior male rugby players from the former Romanian national team were assessed on body composition using a segmental multi-frequency bio-impedance analyzer InBody 720 (The Body Composition Analyzer – South Korea). We compared the results from both the preseason and the regular season 2012 with the international norms for elite players and we categorized the data by playing positions. Results: We have analyzed the amount of lean mass on each limb (kg), body water content (l), percentage of body fat, bone mineral and protein content (kg). We observed that the number of injuries is directly correlated to high levels of body fat percentage, low lean mass, and edema scores. Conclusions: The risk of injury can be identified among elite rugby players not only by using fitness tests, but also by using a simple and objective test of body composition. These results show how important it is to monitor the level of body fat, lean muscle mass and muscular development in order to modify nutrition and food habits, individualize trainings and thus reduce the number of injuries.

AbstractObjectiveAlthough dietary supplement use is increasing in Europe and the USA, little research involving adults’ beliefs regarding dietary supplements has been conducted. Therefore, the present study aimed to explore and compare users’ and non-users’ beliefs towards dietary supplements.DesignThirteen focus group discussions were conducted of which seven groups were dietary supplement users and six groups were non-users. Based on the socio-cognitive factors of the Integrated Change Model, a semi-structured topic guide was set up. The discussions were audio-recorded and subjected to qualitative content analysis, applying the framework approach.SettingData were collected in Maastricht, the Netherlands, in 2014 and 2015.SubjectsIn total fifty-six individuals participated in the study, of whom twenty-eight were dietary supplement users and twenty-eight non-users. The average age of participants was 42·9 years.ResultsDietary supplement users’ attitude beliefs were mainly related to mental and physical health enhancement, illness prevention and curative health benefits. Users were critical of the nutritional knowledge of health professionals and of the quality of food products. Non-users were convinced that the human body does not need any support and that regular food is enough to cover one’s nutritional needs. Users and non-users held comparable beliefs regarding the definition and risks of dietary supplements, and perceived social influences.ConclusionsIn their decision about dietary supplement use, both groups were guided by their own convictions to a great extent. Both groups would benefit from improved understanding of the health effects of dietary supplements to improve informed decision making.

ObjectivesConcerns regarding marked differences in the weights and body composition of young rugby players competing within the same age groups have led to the suggestion of alternative models for grouping young players. The aims of this study were (1) to compare variance in the body size and body composition of schoolboy rugby players (9 to 14 years), across weight- and age-grading models, and (2) to identify morphotypes for the weight model using Hattori’s body composition chart.Materials and MethodsSkinfold thickness measurements were used to assess body fat mass (BF), fat-free mass (FFM), body fat mass index (BFMI), and fat-free mass index (FFMI). Standardized measure of height and weight were taken for all participants. Data were grouped according to the age categories of the French Rugby Federation (U11: Under 11 years, U13: Under 13 years, and U15: Under 15 years), and to the weight categories (W30–44.9; W45–59.9; and W60–79.9) carried out from 25th and 75th weight percentile in each age category. Body mass index status (NW normal-weight versus OW/OB overweight/obese) was considered. Extreme morphotypes are characterized from BFMI and FFMI in the weight-grading model on Hattori’s body composition chart.ResultsThe dispersion of anthropometric characteristics decreased significantly for the weight model, except for height in all groups and BFMI for U13. Among NW, 3, 1.8, and 0% upgraded; 18.2, 68.7, and 45.5% downgraded; among OW, 50, 21.5, and 12.5%; and among OB, 91.3, 83.3, and 74.6% upgraded, respectively, in U11, U13, U15. FFMI/BFMI were correlated in U11 (r = 0.80, p &lt; 0.001), U13 (r = 0.66, p &lt; 0.001), and U15 (r = 0.77, p &lt; 0.001). There was no significant correlation in W45–59.9 and low correlations in W30–44.9 (r = 0.25, p &lt; 0.001) and W60–79.9 (r = 0.29, p &lt; 0.001). Significant grading difference between the centroids (p &lt; 0.05) and the distribution deviates from centroids of BFMI and FFMI (p &lt; 0.0001) were noted between the two models. Thirteen players were located in adipo-slender, twenty-three in adipo-solid, twenty-two in lean-slender, and two located in the lean-solid morphotype in weight model.ConclusionA weight-grading model should be considered to limit mismatches in anthropometric variables. However, variations of body composition also persisted for this model. Hattori’s body composition chart allowed more detailed examination of morphological atypicalities among schoolboy rugby players.

AbstractMultiple studies have elucidated the antioxidant properties of Se, which are now well known among the nutrition and biomedical science communities. Recently, considerable interest has been focused on the possible association between Se exposure and risk of metabolic disease, such as lipid dysregulation; however, there is limited epidemiological data on this topic. The present study aimed to investigate associations between toenail Se levels and dyslipidaemia or individual lipid levels, and to examine the effect of dietary supplement use on these associations. We analysed baseline data from a cohort in the Yeungnam area, including 232 men and 269 women. Information on demographic, dietary and lifestyle characteristics was obtained through a self-reported questionnaire. Se levels in toenail specimens were measured using neutron activation analysis. Fasting blood lipid levels were measured during medical examinations. After adjusting for multiple confounding variables, we observed no association between toenail Se levels and dyslipidaemia or individual lipid profiles. However, the association was modified by dietary supplement use. Among the supplement users, higher toenail Se levels were associated with a higher prevalence of lipid dysregulation, whereas non-users exhibited a lower prevalence of lipid dysregulation. Associations between toenail Se levels, lipid levels and dyslipidaemia may be influenced by taking dietary supplements. Future large-scale, prospective cohort studies should be conducted to further evaluate the association between Se levels in the body and metabolic health effects in light of increasing rates of dietary supplement use.

Dietary Supplement Use

Introduction We examined the dietary intake of iron, zinc and folate, estimated from both food and supplement sources, in 2019 pregnant women who participated in the Prenatal Health Project (PHP). The PHP recruited pregnant women from ultrasound clinics in London, Ontario, in the years 2002–2005. Methods Participants completed a telephone survey, which included a food frequency questionnaire and questions on dietary supplement use. Frequencies of use of dietary supplements were generated. Nutrient intake values were estimated from food and supplement sources, and summed to calculate total daily intake values. Results Most women took a multivitamin supplement, and many women took folic acid and iron supplements; however, one-fifth of the sample did not take any supplements providing any of the three micronutrients. Despite being of a higher socio-economic status overall, significant proportions of the cohort ranked below the recommended dietary allowance values for iron, zinc, and folate. This suggests there may be other barriers that impact dietary practices. Conclusion Further research is required on how to better promote supplement use and a healthy diet during pregnancy.

Background. Rugby is a physically demanding body contact sport. Optimising dietary intake and body composition can positively affect the performance of rugby athletes.Objectives. To determine the body composition, habitual and game-specific nutritional practices of FNB Maties Varsity Cup (MVC) rugby players.Methods. A descriptive, cross-sectional study with an analytical component was conducted. Of all the MVC rugby players (N=35), 18 completed the sections on body composition and match-day dietary intake, while 11 completed the habitual dietary intake section. Body composition data were collected by an International Society for the Advancement of Kinanthropometry-accredited biokineticist. Habitual dietary intake data (via a self-administered 7-day food record) and match-day dietary strategies (via telephonic 24-hour recall interview) were collected and compared with nutritional requirements reported by the International Olympic Committee, the American Dietetic Association, the American College of Sports Medicine and the International Society of Sport Nutrition.Results. Forwards had significantly higher weight (p=0.01), sum of seven skinfolds (p=0.01), percentage body fat (p=0.02), fat mass (p=0.01) and fat-free mass (p=0.01) than backs. Compared with current recommendations, group habitual dietary intake (mean (stand­ard deviation)) was inadequate for total energy (45.4 (9.0) kcal/kg body weight (BW)), carbohydrate (4.3 (0.4) g/kg BW), polyunsaturated fatty acids (6.2 (1.7)% of total energy (TE)), calcium:protein ratio (6.5:1 (3.5:1)) and copper (2.3 (0.4) mg), while displaying higher-than-recommended intakes for total protein (2.4 (0.7) g/kg BW), fibre (37.7 (7.3) g/day), total fat (33.8 (4.3)% TE), saturated fatty acids (11.2 (13.1)% TE), cholesterol (766.3 (371.8) mg) and niacin (45.2 (6.9) µg). Habitual supplement use was high at 91% (n=10/11). Nutritional match-day strategies were excessive for protein (1.2 (0.6) g/kg BW) and fat (0.9 (0.4) g/kg BW) in the pre-event meal, inadequate for energy and carbohydrate during the game and excessive for alcohol (54.4 (59.9) g) after the game.Conclusion. Forwards and backs differed significantly in various body composition measurements. In relation to observed practices, hab­it­ual dietary intake and nutritional match-day strategies were suboptimal, with high reported supplement use. Players in this sport potentially could benefit from specialist input to optimise dietary strategies and body composition in order to enhance performance.
