ABSTRACT Introduction: It is known that ingestion of carbohydrate-containing beverages can enhance sports perfor-mance. 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 mal-todextrin-based drink.

Aim. The efficacy of triphala on lipid profile, blood glucose and anthropometric parameters and its safety were assessed. Methods. Databases such as PubMed, ScienceDirect, Web of Science, and Thai Library Integrated System (ThaiLIS) were systematically searched to review current evidence of randomized controlled trials (RCT) on triphala. RCTs investigating the safety and efficacy of triphala on lipid profile, blood glucose and anthropometric parameters were included. Study selection, data extraction, and quality assessment were performed independently by 2 authors. Results. Twelve studies on a total of 749 patients were included. The triphala-treated groups showed significantly reduced low-density lipoprotein-cholesterol, total cholesterol and triglyceride in 6 studies. Five RCTs demonstrated triphala-treated groups led to statistically significant decrease in body weight, body mass index and waist circumference of obese patients. Moreover, triphala significantly decreased fasting blood glucose level in diabetic patients but not in people without diabetes. No serious adverse event associated with triphala was reported during treatment. Conclusions. This review summarized a current evidence to show triphala might improve the lipid profile, blood glucose, the body weight, body mass index and waist circumference under certain conditions. However, large well-designed RCTs are required to confirm this conclusion.

BACKGROUND Balance training in young adults may increase coordination, cognitive function or the symmetry of strength on both sides of the body. It is an essential tool for injury or fall prevention and a precondition for becoming a professional athlete. OBJECTIVE The aim of this study was to assess the effect of Xbox 360 Kinect training on postural balance in young, healthy individuals. METHODS The study enrolled 75 individuals who were randomly assigned to three equal groups. The first group (Group VR) performed exercises on an Xbox 360 Kinect console, and the second group (Group T) performed conventional all-round exercises. The third group was a control group (Group C). Each group underwent balance assessments on the Biodex Balance posturographic platform, including the Balance Error Scoring System test, before and after the training cycle. The level of statistical significance was set at P<.05. RESULTS Group VR and Group T achieved statistically significant improvements in the sway index compared with baseline. Group T gained significant decrease in the sway index on the unstable surface (P=.002). Group VR and group T demonstrated significant decreases in the mean sway index on stable and unstable surfaces (group VR — P=.035; group T — P=.001) Group C did not achieve a statistically significant improvement in the sway index. None of the groups demonstrated a statistically significant decrease in the test error count. CONCLUSIONS Virtual reality in the form of video games played on an Xbox 360 Kinect console may be an effective method of balance training in healthy individuals.

Introduction: There is a strong relationship between malnutrition and increased length of hospitalization and morbidity and mortality. Studies have shown that malnourished patients can have up to twenty times more complications than eutrophic ones. In critically ill patients, there is a tendency to catabolism, resulting in the loss of lean body mass, which when it reaches 40% is usually lethal. Methods: A quantitative, descriptive study was conducted on adults from both genders, admitted to the intensive care unit (ICU) of a university hospital, from March to December 2018. The following variables were collected from the evaluation and nutritional records: length of hospitalization in the ICU, date of discharge or death, nutritional risk through specific screening, height, weight and arm circumference (AC). For the screening, the Nutric score was used. For the nutritional evaluation, the body mass index (BMI) and AC indicators and the classifications recommended by the World Health Organization (2004) and Blackburn and Thornton (1979) were used. After collecting the data, they were analyzed in the Statistical Package for Social Sciences (SPSS) 13.0 and for the association of the variables the Chi-square test was used, considering statistical difference when the p value <0.05. Results: The sample consisted of 116 patients, mostly female (53.4%) whose median age was 46 years (interquartile range IQR 31-53). Regarding the frequency of nutritional risk, most patients (61.5%) had a low score. There was an important frequency of malnutrition, according to the AC indicator (73%), although BMI (43.5%) showed eutrophy. Even though most patients had low nutritional risk, those with high nutritional risk (38.5%) had a higher tendency to mortality, however, not statistically confirmed (p> 0.05). There was also a tendency of association between death and malnutrition, although no statistical significance was shown(p> 0.05). Conclusion: Patients at nutritional risk and/or malnutrition appear to be vulnerable to worse clinical outcomes.

Adolescent judo athletes who train in tropical climates may be in a persistent state of dehydration because they frequently restrict fluids during daily training sessions to maintain or reduce their body weight and are not given enough opportunities to drink.Purpose:Determine the body hydration status of adolescent judo athletes before, immediately after, and 24 h after (24H) a training session and document sweat Na+ loss and symptoms of dehydration.Methods:Body mass and urine color and specific gravity (USG) were measured before, after, and 24 h after a training session in a high-heat-stress environment (29.5 ± 1.0°C; 77.7 ± 6.1% RH) in 24 adolescent athletes. Sweat sodium loss was also determined. A comparison was made between mid-pubertal (MP) and late pubertal (LP) subjects.Results:The majority of the subjects started training with a significant level of dehydration. During the training session, MP subjects lost 1.3 ± 0.8% of their pretraining body mass whereas LP subjects lost 1.9 ± 0.5% (P < .05). Sweat sodium concentration was 44.5 ± 23.3 mmol/L. Fluid intake from a water fountain was minimal. Subjects reported symptoms of dehydration during the session, which in some cases persisted throughout the night and the next day. The 24H USG was 1.028 ± 0.004 and 1.027 ± 0.005 g/mL for MP and LP, respectively.Conclusions:Adolescent judo athletes arrive to practice with a fluid deficit, do not drink enough during training, and experience symptoms of dehydration, which may compromise the quality of training and general well-being.

CONTEXT AND OBJECTIVE: Increasing obesity is starting to occur among Brazilians. The aim of this study was to investigate the weight and length of children under two years of age in relation to sociodemographic variables and according to whether they were breastfed. DESIGN AND SETTING: Cross-sectional randomized study conducted in 2004-2005, based on the declaration of live births (SINASC) in Campinas, Brazil. METHODS: 2,857 mothers of newborns were interviewed and answered a questionnaire seeking socioeconomic and breastfeeding information. The newborns' weights and lengths were measured at the end of the interviews and the body mass index was calculated. Percentiles (< 15 and > 85) and Z-scores (< -1 and > +1) were used for classification based on the new growth charts recommended by WHO (2006). The log-rank test, multiple linear regression and binomial test (Z) were used. The statistical significance level used was 5%. RESULTS: The predominant social level was class C. The median for exclusive breastfeeding was 90 days; 61.25% of the children were between P15 and P85 for body mass index and 61.12% for length, respectively. Children whose mothers studied for nine to eleven years and children whose mothers were unemployed presented lower weight. Children whose mothers worked in health-related professions presented lower length when correlated with breastfeeding. CONCLUSION: The breastfeeding, maternal schooling and maternal occupation levels had an influence on nutrition status and indicated that obesity is occurring in early childhood among the infants living in the municipality.

We investigated the impact of nutrient intake on hydration biomarkers in cyclists before and after a 161 km ride, including one hour after a 650 mL water bolus consumed post-ride. To control for multicollinearity, we chose a clustering-based, machine learning statistical approach. Five hydration biomarkers (urine color, urine specific gravity, plasma osmolality, plasma copeptin, and body mass change) were configured as raw- and percent change. Linear regressions were used to test for associations between hydration markers and eight predictor terms derived from 19 nutrients merged into a reduced-dimensionality dataset through serial k-means clustering. Most predictor groups showed significant association with at least one hydration biomarker: (1) Glycemic Load + Carbohydrates + Sodium, (2) Protein + Fat + Zinc, (3) Magnesium + Calcium, (4) Pinitol, (5) Caffeine, (6) Fiber + Betaine, and (7) Water; potassium + three polyols, and mannitol + sorbitol showed no significant associations with any hydration biomarker. All five hydration biomarkers were associated with at least one nutrient predictor in at least one configuration. We conclude that in a real-life scenario, some nutrients may serve as mediators of body water, and urine-specific hydration biomarkers may be more responsive to nutrient intake than measures derived from plasma or body mass.

The aim was to analyze the influence of competitive round on muscle strength, body-fluid balance, and renal function in elite badminton players during a real competition. Body mass, jump height during a countermovement jump, handgrip force, and urine samples were obtained from 13 elite badminton players (6 men and 7 women) before and after the 2nd-round and quarterfinal matches of the national Spanish badminton championship. Sweat rate was determined by using prematch-to-postmatch body-mass change and by weighing individually labeled fluid bottles. Sweat rates were 1.04 ± 0.62 and 0.98 ± 0.43 L/h, while rehydration rate was 0.69 ± 0.26 and 0.91 ± 0.52 L/h for the 2nd round and quarterfinals, respectively. Thus, dehydration was 0.47% ± 1.03% after the 2nd round and 0.23% ± 0.43% after the quarterfinals. There were no differences in prematch-to-postmatch jump height, but jump height was reduced from 37.51 ± 8.83 cm after the 2nd-round game to 34.82 ± 7.37 cm after the quarterfinals (P < .05). No significant differences were found in handgrip force when comparing prepost matches or rounds, although there were significant differences between dominant and nondominant hands (P < .05). The succession of rounds caused the appearance of proteinuria, hematuria, glycosuria, and higher nitrite and ketone concentrations in urine. Rehydration patterns during a real badminton competition were effective to prevent dehydration. A badminton match did not affect jump height or handgrip force, but jump height was progressively reduced by the competitive round. Badminton players’ renal responses reflected diminished renal flux due to the high-intensity nature of this racket sport.

Background: Adolescent is characterised by rapid physical growth and sexual development, accompanied by changes in the percentage of body fat. Obesity and underweight are one of the most prominent problems of the modern society which consists of a wide range of short-term and long-term complications. The rising prevalence of childhood obesity is directly related to the vascular, metabolic condition and risk factor to cognitive decline or dementia. Under-weight is also often associated with acute and chronic medical complications like Anorexia nervosa, low bone density and mass with impaired immune system and increased mortality rate. Therefore purpose of this study is to identify early signs of impaired BMI as a cause of cognitive impairment and prevent the child obesity and underweight to overcome the future health risk factors. The aim of this study is to find a correlation between BMI and MMSE score in Indian adolescent females. Methodology: 31 female subjects with mean age 16±3 years were selected according to random sampling in this study. The Quetlets formula was used to measure body mass index. Group division for Underweight, Normal and Over-weight was done for the BMI score then Score of MMSE, a measure of cognition was taken. Data was analyzed using SPSS version 16. The Karl Pearsons Coefficient correlation was calculated to see correlation between BMI and MMSE cognitive function. P < 0.05 was considered of statistical significance. Result: The study found correlative change in variables as observed in group A MMSE mean 25.84±3.83 and BMI mean 16.10±1.08 with P<0.05 i.e which was found statically significant.
