Abstract Background The aim of this study was to analyze the consumption of sports supplements (SS) in competitive level fencers and compare differences based on sex and competitive level (international and national). Methods A total of 49 fencers (18 men and 31 women) of national (n = 16) and international (n = 33) level completed a questionnaire with questions about SS consumption and the possible repercussions on health and / or sports performance. The results were analyzed based on the different categorizations established by the Australian Institute of Sport (AIS), as well as by sex and level of competence to which the participants belonged to. Results 46.9% of fencers have consumed SS with the main motivation being performance improvement (34.2%). Medical doctors were the individuals who were more likely to advise men to consume SS (50.0% vs 5.6%; OR = 3.29 [1.50–7.20]). Friends were most likely to advise women (38.9% vs 8.3%; OR = 1.75 [1.05–2.93]). The most consumed SS were sport drinks (44.9%), vitamin C (43.4%), sport bars (38.8%), and caffeine (28.6%). In regards to the SS categories, it was observed differences in the interaction level·sex in medical supplements (p = 0.017). In addition, there was a higher prevalence of whey protein consumption in women (25.8% vs 0%; p = 0.020) and iron consumption in men (33% vs 6.5%; p = 0.039). Conclusions The prevalence of SS use in fencers is within the values previously reported in athletes of the same competitive level. There were no differences by sex and competitive level in the total consumption of SS, nor in each of the groups of level of evidence, being sport drinks, bars and caffeine the most consumed SS.

The sports performance of dinghy sailors is determined by their state of nutrition and hydration. Sports supplementation plays a prominent role in elite sailors, being essential in periods of competition due to its characteristics. This study aims to analyze the consumption of sports supplements (SS) in the different categories and groups of sailors based on the level of evidence, differentiating according to sex, competitive level, and type of boat. A total of 42 sailors from national and international levels and belonging to the Laser, 420, Techno-293 and RS:X classes participated in this study. They completed a questionnaire with questions about the consumption of SS and the possible repercussions on health and/or sports performance. The results were analyzed based on the different categorizations and group organization recently established by the Australian Institute of Sport (AIS), as well as by sex, level of competition and class to which the participants belonged. The male sailors and those who competed internationally had a higher prevalence in the consumption of SS. Among the classes of vessels studied, class 420 had the lowest SS consumption. SS intake was higher during competition days, regardless of sex or level of competition. Based on the classification established by the AIS, statistically significant differences were observed in sex, level of competition, and the type of boat.

Context: The use of creatine as a dietary supplement has become increasingly popular over the past several decades. Despite the popularity of creatine, questions remain with regard to dosing, effects on sports performance, and safety. Evidence Acquisition: PubMed was searched for articles published between 1980 and January 2017 using the terms creatine, creatine supplementation, sports performance, and dietary supplements. An additional Google search was performed to capture National Collegiate Athletic Association–specific creatine usage data and US dietary supplement and creatine sales. Study Design: Clinical review. Level of Evidence: Level 4. Results: Short-term use of creatine is considered safe and without significant adverse effects, although caution should be advised as the number of long-term studies is limited. Suggested dosing is variable, with many different regimens showing benefits. The safety of creatine supplementation has not been studied in children and adolescents. Currently, the scientific literature best supports creatine supplementation for increased performance in short-duration, maximal-intensity resistance training. Conclusion: While creatine appears to be safe and effective for particular settings, whether creatine supplementation leads to improved performance on the field of play remains unknown.

ABSTRACT Objective: To investigate the prevalence and establish the profile of the consumption of dietary supplements among Brazilian athletes. Methods: A total of 182 athletes of both genders from 20 different sports participated in this study. The athletes answered a questionnaire containing sociodemographic and sports-related questions and were interviewed about the consumption of dietary supplements. Results: Forty seven percent of athletes reported having consumed at least one type of dietary supplement and 38% said they use more than three different types of supplements concurrently. Whey protein was the most commonly consumed supplement, and the most frequently mentioned reason for its consumption was performance improvement. The main source of information was coaches, and individual sport athletes were the greatest consumers and the most likely to seek dietary supplement. Conclusion: Approximately half of the participants used dietary supplements, which on most occasions were recommended by coaches. The consumption profile also revealed multiple supplementation practice and showed that nutrition education is essential for this specific population.

Context: Sleep schedule adjustments are common requirements of modern-day athletes. Many nonpharmacologic and pharmacologic strategies exist to facilitate circadian rhythm shifts to maximize alertness and performance during competition. This review summarizes the evidence for commonly used pharmacologic agents and presents recommendations for the sports medicine provider. Evidence Acquisition: MEDLINE searches were performed using the following keywords: sleep aids, circadian rhythm adjustment, athletes and sleep, caffeine and sports, melatonin and athletes, and sleep aids and sports. Pertinent articles were extracted and discussed. Study Design: Clinical review. Level of Evidence: Level 2. Results: There are very few available studies investigating pharmacologic sleep aids in athletes. Data from studies involving shift workers and airline personnel are more abundant and were used to formulate recommendations and conclusions. Conclusion: Melatonin, caffeine, and nonbenzodiazepine sleep aids have a role in facilitating sleep schedule changes in athletes and maximizing sports performance through sleep enhancement.

La literatura científica sobre el consumo de suplementos deportivos (SD) en levantamiento de potencia es escasa. El objetivo del presente estudio fue evaluar el consumo de SD y la ingesta de proteína dietética en un grupo de levantadores de peso que compiten a nivel nacional. Se utilizaron enfoques experimentales y no experimentales, registrándose un total de 22 cuestionarios y diarios dietéticos. Los resultados muestran que el 100% de los sujetos afirma haberlos consumido en alguna ocasión y el 96,9% los consume en la actualidad. Los SD más consumidos por la muestra son monohidrato de creatina (100%), cafeína (95%), proteína de suero (92%), aminoácidos ramificados (73%), barritas energéticas (68%), ácidos grasos omega-3 (63%), bebidas isotónicas (63%) y complejos vitamínicos (59%). La mayoría (36,4%) no prevé en qué momento del día consumirlos. Durante el transcurso del diario dietético, los SD más consumidos fueron la proteína de suero y el monohidrato de creatina; además, los sujetos ingirieron una media de 2.37 g/kg/día de proteína dietética. Teniendo en cuenta el presente estudio y otras aportaciones en la bibliografía, podemos afirmar que la ingesta de proteína dietética en levantadores de peso es suficiente para la ganancia y preservación de masa muscular; y que el consumo de SD es elevado y cada vez más frecuente, lo que puede ocasionar serios riesgos de salud pública debido a la falta de información existente en el sector, e inespecífica y mejorable legislación de los SD en Europa.Abstract. The scientific literature on the consumption of sports supplements (SS) within powerlifting is scarce. The goal of the study was to evaluate the consumption of SS and dietary protein intake in a national-level powerlifting group. Experimental and non-experimental approaches were used with a total of 22 surveys and dietary logs. The results show that 100% of the subjects claimed to have consumed SS at some point and 96.9% of them are currently consuming them. The most consumed SS are creatine monohydrate (100%), caffeine (95%), whey protein (92%), branched-chain amino acids (73%), energy bars (68%), omega-3 fatty acids (63%), isotonic drinks (63%) and multivitamin complex (59%). Most of the subjects (36.4%) do not plan when to consume them throughout the day. According to the dietary logs of the subjects, the most taken SS were whey protein and creatine monohydrate; furthermore, the subjects consumed an average of 2.37 g/kg/day of dietary protein. Taking into account this study and other studies, we can confirm that the protein intake of powerlifters is enough to fuel muscle gain and maintenance; and that the consumption of SS is high and that it is continuously growing, which may cause serious public-health issues in the future due to the lack of information within the fitness industry and the unspecific and undeveloped legislation of SS within Europe.

ABSTRACT Introduction Since its debut at the 1996 Atlanta Olympics, beach volleyball has grown on the international sports scene. An extensive collection of data from several countries and levels of competition will provide a database that can be used to characterize beach volleyball players and define references for training stages. Objective The purpose of this study was to describe and compare the anthropometric profiles of Spanish male and female beach volleyball players at different levels of competition in relation to sports performance. Methods The sample comprised 150 players participating in the 2011 Spanish Beach Volleyball Championships (Under 19, Under 21, and Senior categories). Using the ranking provided by the Royal Spanish Volleyball Federation, the subjects were distributed by performance level (level 1: players ranked first to fourth; level 2: players ranked fifth to ninth; and level 3: players ranked tenth to seventeenth). The study comprised a group of male players, with 18 level 1 ( M1 ), 39 level 2 ( M2 ), and 22 level 3 players ( M3 ), and a group of female players, with 18 level 1 ( F1 ), 41 level 2 ( F2 ), and 12 level 3 players ( F3 ). Results The top level male sample ( M1 ) had a significantly lower average age (19.33 years) than the men’s international elite players (30 years). The top Spanish players of both genders had much lower values for height and body weight than the international elite players. Conclusions Height and fat component are responsible for the differences between top and lower level beach volleyball players, for both men and women. Moreover, as the level of performance increases, players are taller and have a lower fat component. In view of the data observed in this study, the talent selection process in Spanish beach volleyball should aim to select taller individuals than at present.

Aims This study investigates the motives and discourses around the decision taken by the Icelandic parliament in 1989 to legalise beer sales after a prohibition of 74 years. A bill was passed in 1988 that allowed the selling of beer in licensed restaurants and the state alcohol monopoly stores. Design The sources used for this study are mainly newspaper articles and other materials and reports published in the period 1980 to 1989. Results The passing of the bill was preceded by many controversial discourses in Iceland. Lobbying groups with commercial interests campaigned for the legalisation of beer, while representatives of the alcoholism movement took no formal stance on the issue, parliamentarians broke from party lines and medical doctors were split into two factions. Common questions included the plausibility of the total consumption model, various understandings of WHO recommendations, diverging interpretations of other countries’ experiences of beer, and different views on how beer would affect individuals suffering from alcoholism. Conclusions The changes in Icelandic alcohol policy to legalise beer were in keeping with contemporary societal processes of globalisation and modernisation, but public health arguments were given less priority. While the decision to legalise beer increased the commercial functions of the state alcohol monopoly, it also strengthened the monopoly's role as an actor in alcohol policy.

Diferentes marcas de três tipos de suplementos esportivos à base de proteína de soro de leite foram avaliadas: 15 do tipo à base de proteína de soro de leite, 4 "hipercalóricos" e 7 barras de proteína. Um procedimento de preparo de amostras foi estudado empregando digestão ácida assistida por micro-ondas para determinar os teores de sódio e potássio usando Espectrometria de Emissão Atômica com Chama (Fotometria de Chama). As concentrações de sódio obtidas variaram na faixa de: 0,30 a 5,9 mg/g, de 0,52 a 2,8 mg/g e de 2,3 a 5,0 mg/g para suplementos a base de proteínas do soro de leite, suplementos hipercalóricos e suplementos em barra de proteína, respectivamente. Enquanto as concentrações de potássio, variaram de: 1,3 a 13 mg/g, de 0,47 a 5,4 mg/g e de 1,7 a 12 mg/g para as mesmas amostras, respectivamente. A razão entre os níveis de sódio e potássio, um parâmetro associado à hipertensão incidente, foi calculada e mostrou que, para algumas amostras, os valores excederam a recomendação da Organização Mundial de Saúde. O método desenvolvido apresentou alta frequência analítica, com boa exatidão e precisão sendo adequado para aplicação em rotinas de controle de qualidade.
