“…This research showed that the incidence of pre-practice dehydration among junior sub-elite athletes in Yogyakarta is high (90.9%), indicating that athletes and their parents do not understand about the seriousness of fulfilling fluid requirement level in their body prior to training. The research result is similar to a research conducted by Spulveda et al which showed that many young athletes started their training in dehydrated conditions [4,5].…”

karate is high intensity sport which often leads to dehydration. The purpose of this study was to identify prepractice hydration status of Indonesian junior sub-elite karate athletes. This descriptive cross-sectional research recruited junior (under-17) sub-elite karate athletes in Yogyakarta, Indonesia. The population sample entailed eleven players (6 male; 5 female, age 14.09 + 2.34 years , weight 50.14 + 10.85 kg, height 1.55 + 0.11 m, BMI 20.65 + 2.03 kg/m 2 ). Hydration status was checked by urine specific gravity (USG) using urine strip test 15-30 minutes before training started. The values of USG were compared with the reference value to categorize the hydration status into good hydration (USG < 1.010), minimal dehydration (1.010 -1.020), and significant dehydration (1.021 -1.030). The study established that 90.9% (n = 10) of the participants suffered from dehydration and 10.1% (n=1) had good hydration before training. Six from 10 dehydrated athletes (60%) were categorized into minimal dehydration and the rest (40%; n = 4) were of significant dehydration. Incidence of prepractice dehydration among junior sub-elite karate athletes in Indonesia was high. Education and promotive strategies are needed to prevent the risk of dehydration during exercise.

“…These findings reinforce the importance of stimulating the water intake at all times of the day for soccer players, once you start practicing sports in dehydration conditions cause changes in the physiological homeostasis, including reduction of blood volume, increased heart rate, increased blood osmolarity, decreased blood flow to the skin, decreased sweating rate and heat loss, increased body temperature and increased perceived exertion 26 . Recognizing the importance of hydration for this population, the consumption from 600 to 1,000 ml of a 6 to 10% carbohydrate solution would be most appropriate in this situation 27,28 .…”

Introduction: It is known that ingestion of carbohydrate-containing beverages can enhance sports performance. However, many teams do not have sufficient financial resources to invest in commercial products and need to prepare their own hydration drinks. Jacuba is a beverage used as sport drink (source of carbohydrate) in soccer clubs in Northeastern Brazil. Objective: To evaluate the influence of two beverages with carbohydrate on blood glucose, dehydration and fatigue in a soccer team of Northeastern Brazil. Methods: Twenty-two soccer players were evaluated in two days of physical training, with ingestion of water ad libitum and two beverages: 1) maltodextrin-based drink, or 2) Jacuba. Capillary blood glucose was measured before and after training. Fatigue was assessed using Borg Scale after exercise. To evaluate the dehydration of the athletes at the end of exercise, the urinalysis test and the verification of the body mass change during the training were performed. Results: Blood glucose changed to 13.1±29.5 mg/dL and 7.6±22.2 mg/dL on training days with consumption of maltodextrin and Jacuba, respectively, without statistical significance. There were no changes in body mass and in water and total fluids intake in the two days of training. The Borg Scale score after training was 15.2±2.6 and 14.9±3.0 for maltodextrin and Jacuba, respectively (p=0.12). Conclusion: Jacuba can be used to improve hydration and maintain blood glucose in soccer players because their results do not differ with those of maltodextrin-based drink.Keywords: soccer; carbohydrates; blood glucose; fatigue; dehydration. de 15,2±2,6 y 14,9±3,0 para maltodextrina y Jacuba, respectivamente (p = 0,12). Conclusión: Se puede utilizar Jacuba para mejorar la hidratación y mantener la glucosa en sangre en jugadores de fútbol, debido a que sus resultados no fueron diferentes de la bebida con maltodextrina.

“…Similar results regarding hydration status on athletes have been reported elsewhere. In a study performed by Castro-Sepúlveda et al (2015) professional soccer players began training sessions with an average USG of 1.026 ± 0.005 (98% dehydration prevalence) [14]. Furthermore, Díaz-Castro et al (2018) observed basketball players with an average USG of 1.021 ± 0.006 (98% dehydration prevalence) [15].…”

Background: Hydration status affects endurance performance. Pre-exercise hydration recommendations target the consumption of high carbohydrate and sodium beverages. Milk, due to its carbohydrate and sodium content, may be considered an effective pre-exercise hydration beverage. Purpose: In a randomized cross-over trial, we compared the effects of an isotonic sport drink (SPD) with skim milk (SM) consumption before a race, on fluid homeostasis and time-trial performance in road cyclists. Methods: Male road cyclists (n = 9; age, 26.8 ± 4.78 years) with 10.8 ± 8.56 years of experience in national competitions, consumed either SPD or SM in doses of 350 mL at 3 h and 350 mL at 1.5 h before a 18.6 km time-trial race. Measurements of body mass, urine specific gravity (USG), urine color and time-trial were compared between drinks (group; g) before and after the race (time; t). Results: The two-way ANOVA showed no differences between SPD and SM in body mass (t, p < 0.0001; g, p = 0.89; t × g, p = 0.54), USG (t, p = 0.01; g, p = 0.63; t × g, p = 0.29) and urine color (t, p = 0.01; g, p = 0.54; t × g, p = 0.28) before or after race. Furthermore, no differences on water consumption during the race (p = 0.55) or time-trial performance (p = 0.84) were observed between trials. Conclusion: Current results may help athletes with different beverages preferences to increase their options of hydration strategies.
