“…The athletes are regularly far away from the coast, and they wear sailing suits made of neoprene and latex materials that do not allow regular perspiration. It has already been noted that most of the sailing athletes are in a negative fluid balance after racing (mean loss for males: - 2.1%; for females: - 0.9%) [14]. In addition, Croatia is a Mediterranean country with a temperature ranging from 15 to 30 degrees Celsius (from March through the end of September, when most sailing occurs), and it is clear that adequate rehydration is difficult to achieve without isotonic drinks.…”

BackgroundAlthough dietary supplements (DSs) in sports are considered a natural need resulting from athletes’ increased physical demands, and although they are often consumed by athletes, data on DS usage in Olympic sailing are scarce. The aim of this study was to study the use of and attitudes towards DSs and doping problems in high-level competitive sailing.MethodsThe sample consisted of 44 high-level sailing athletes (5 of whom were female; total mean age 24.13 ± 6.67 years) and 34 coaches (1 of whom was female; total mean age 37.01 ± 11.70). An extensive, self-administered questionnaire of substance use was used, and the subjects were asked about sociodemographic data, sport-related factors, DS-related factors (i.e., usage of and knowledge about DSs, sources of information), and doping-related factors. The Kruskal-Wallis ANOVA was used to determine the differences in group characteristics, and Spearman’s rank order correlation and a logistic regression analysis were used to define the relationships between the studied variables.ResultsDS usage is relatively high. More than 77% of athletes consume DSs, and 38% do so on a regular basis (daily). The athletes place a high degree of trust in their coaches and/or physicians regarding DSs and doping. The most important reason for not consuming DSs is the opinion that DSs are useless and a lack of knowledge about DSs. The likelihood of doping is low, and one-third of the subjects believe that doping occurs in sailing (no significant differences between athletes and coaches). The logistic regression found crew number (i.e., single vs. double crew) to be the single significant predictor of DS usage, with a higher probability of DS consumption among single crews.ConclusionBecause of the high consumption of DSs future investigations should focus on real nutritional needs in sailing sport. Also, since athletes reported that their coaches are the primary source of information about nutrition and DSs, further studies are necessary to determine the knowledge about nutrition, DSs and doping problems among athletes and their support teams (i.e., coaches, physicians, and strength and conditioning specialists).

“…Only two previous studies have directly recorded hydration status in competitive sailors. Slater and Tan reported dehydration greater than 2% of body weight in sailors, potentially leading to performance decrements (Slater & Tan, 2007). Lewis et al reported significant body mass losses in competitive sailors even in cold conditions despite ad libitum fluid intake (Lewis, Fraser, Thomas, & Wells, 2013).…”

“…Additionally, athletes remain on the water for long durations with limited access to fluids due to the nature of the sport and lack of space in the boat (Allen & De Jong, 2006). The small amount of research specific to sailing performance and nutrition indicates that sailors fail to prevent dehydration greater than -2% of body weight throughout competition (Slater & Tan, 2007). Also, elite sailors demonstrate a lack of knowledge regarding sports nutrition, including guidelines for fluid consumption during exercise (Legg et al, 1997).…”

The purpose of this manuscript is to assess hydration status of elite young sailing athletes during World Championship competition. 12 young elite male Laser Class sailors (age: 15.8±1.1 y, height: 1.74±0.1 m, weight: 65.1±1.5 kg, body fat: 12.5±3.1%, training experience: 7.0±1.2 y) participated in this descriptive study. After three-day baseline bodyweight measurements, hydration status was assessed via pre-and post-race body weights, urine specific gravity, and thirst ratings via a visual analog scale during 4 consecutive days of racing.Measurements and data collection took place at the same time each racing day, with mean environmental temperature, humidity, and wind speed at 23.0±0.8 o C, 64-70% and 9±1 knots, respectively. Average racing time was 130±9 min. Body weight was significantly decreased following each race-day as compared to pre-race values (day 1: -1.1±0.2, day 2: -2.5±0.1, day 3: -2.8±0.1, and day 4: -3.0±0.1% of body weight; P<0.05). The participants exhibited dehydration of -2.9±0.2 and -5.8±0.2% of body weight before and after the 4th racing day as compared to the 3-day baseline body weight. Urine specific gravity (pre -post  day 1:1.014-1.017; day 2: 1.019-1.024; day 3: 1.021-1.026; day 4: 1.022-1.027) and thirst (pre -post  day 1: 2.0-5.2; day 2: 3.2-5.5; day 3: 3.7-5.7; day 4: 3.8-6.8) were also progressively and significantly elevated throughout the four days of competition. The data revealed progressive dehydration throughout four consecutive days of racing as indicated by decreased body weight, elevated urine concentration, and high thirst.

“…Estudos apontam as diversas exigências necessárias para a prática da vela, como: demandas de força, equilíbrio, coordenação, resistência, nutrição adequada, além de boas condições psicológicas para interpretar adequadamente ações do vento e do mar, tomar decisões rápidas, e manter a concentração e o foco de atenção (SLATER; TAN, 2007;DUARTE, 2007;MACKIE;LEGG, 1999;DAUTY et al, 2006;BERNARDI et al, 2007;CUNNINGHAM;HALE, 2007;LÉGER et al, 2007;PARDAL;SPURWAY, 2007;VALLEJO;ROSIQUE;GONZÁLEZ-MORO, 2008). Somado a isso, também se torna necessária uma boa atenção em tarefas individuais e simultâneas, estando estas relacionadas à capacidade do velejador em automatizar tarefas (ABERNETHY et al, 2007).…”

“…A prática da vela consiste em uma atividade esportiva que, devido às suas complexas características, exige fisicamente do atleta e o estimula intelectualmente (SLATER; TAN, 2007). Um barco a vela sempre navega movimentado pelo vento, pois não é permitido o uso de motores ou outros meios de propulsão durante as regatas (MAIA, 2008).…”
