The effect of nutrition education sessions on energy availability, body composition, eating attitude and sports nutrition knowledge in young female endurance athletes.

Nutrition knowledge plays a pivotal role in shaping dietary habits and food choices, particularly in the realm of sports nutrition. This study investigates the effects of a series of nutrition education sessions conducted by a registered dietitian on energy availability, various anthropometric measurements, eating attitudes, and sports nutrition knowledge in young female endurance athletes aged 15-18 years (football, basketball, volleyball) who engage in training for more than 10 h per week (n = 83). Participants were randomly divided into two groups with 45 individuals receiving six physical nutrition education lectures, and the remaining 38 participants receiving no nutrition education. Participants completed the low energy availability in females questionnaire (LEAF-Q), Eating Attitude Test (EAT-26), and Sports Nutrition Knowledge Questionnaire (SNKQ). Energy and nutrient intakes were evaluated through 3-day food records, while exercise energy expenditure was assessed using 3-day activity logs. All of the questionnaires were repeated after 6 months. At baseline, the prevalence of LEA among athletes was determined to be 63.8%. In the intervention group, energy availability (EA) and SNKQ scores increased, and LEAF-Q scores decreased significantly (p < 0.05). However, there was no significant change in EAT-26 scores between the two groups. Energy intake, weight, fat-free mass, and resting metabolic rate have been increased significantly in the intervention group (p < 0,05). These findings suggest that nutrition education proves beneficial in enhancing dietary intake, positively influencing body composition, and improving nutrition knowledge, ultimately contributing to increased energy availability in female athletes over the short term.

Effects of Hardaliye, a Fermented Grape Drink, on Oxidative Stress, Lipid Profile, and Blood Pressure in Young Soccer Players: A Randomized Controlled Trial.

OBJECTIVE: Hardaliye, a traditional fermented grape juice, can prevent imbalances in the antioxidant defense systems of soccer players. Hardaliye is mainly produced through the fermentation of grapes, sour cherry leaves, and mustard seeds and is consumed as a drink. This study was aimed at investigating the effects of hardaliye consumption on oxidative stress parameters, lipid profile, and blood pressure in young elite soccer players. METHODS: In this single-blind, randomized, placebo-controlled, parallel-design study, while the participants in one of the groups consumed 250 mL/d of hardaliye drink (Hardaliye Group), the participants in the other group consumed placebo drink (Placebo Group) for 28 days. Three-day food record and blood samples were taken from the soccer players and their blood pressure was measured. RESULTS: Nutrient intakes in both groups were similar at the beginning and end of the study (p > 0.05). Dietary carbohydrates and vitamin A, E, and C intakes were below the recommended levels in both groups. Hardaliye consumption significantly increased the serum total antioxidant capacity level but significantly decreased serum total oxidation status, oxidative stress index, malondialdehyde, and nitric oxide levels compared to the Placebo Group (p < 0.05). Lipid parameters and diastolic blood pressure levels were not significantly different between the groups (p > 0.05). Hardaliye consumption significantly decreased systolic blood pressure compared to that in the Placebo Group (p < 0.05). CONCLUSION: Hardaliye consumption in young elite soccer players showed antioxidative effects and decreased systolic blood pressure but did not affect their lipid profiles.

Vegetable and Fruit Consumption and Its Relationship with Body Mass Index in Adults: A Cross-Sectional and Seasonal Research from Türkiye.

This study examines the relationship between fruit and vegetable consumption and the BMI in Türkiye. In this cross-sectional study, which 6332 adults were included, fruit and vegetable consumption, and preferences were collected. The quantities of vegetables and fruits were classified based on the WHO and the national recommendations. Of the adults (33.39 ± 12.59 years), 52.9% of men and 39.7% of women had an above-normal BMI. Based on WHO recommendations, overweight and obese people consumed less vegetables and fruits compared to their counterparts (ORs for women, overweight: 1.2, obese: 1.3; ORs for men, overweight: 1.3, obese: 1.5; 95% CI). The regression analysis revealed that the quantities of vegetable and fruit intake were higher in young individuals, men, and married people. Although the majority consume more than 400 g/day of vegetables and fruits, the intake is inadequate in people with obesity.

Assessment of hydration status of elite young male soccer players with different methods and new approach method of substitute urine strip.

BACKGROUND: The purpose of the study is to determine and compare the hydration status with different methods and determine fluid intake, dehydration percentages and sweat rate of 26 young male soccer players (15 ± 1.2 years) before an important competition. More specifically, the study aims at validating the urine strip and advising the players to use it as an easy and practical method. METHODS: Measurements of urine analysis were taken from the urine sample of the participants before breakfast and conducted for 3 consecutive days before the competition. Hydration status was assessed through analysis of urine color, urine specific gravity (USG) (laboratory, strip, refractometry), and osmolality. The players' dehydration percentages and sweat ratio were calculated. RESULTS: The average values for all samples were 3 ± 1 for color, and 1.021 ± 4 g/cm(3) for USG (laboratory), and 1.021 ± 3 g/cm(3) for USG (strip), and 1.021 ± 4 for USG (refractometry), and 903 ± 133 mOsm/kg for osmolality. USG (strip) was highly correlated with USG (laboratory), USG (refractometry) (r = 0.8; P < 0.01) and osmolality (r = 0.7; P < 0.01), and moderately correlated with urine color (r = 0.4; P < 0.05). The mean dehydration percentage and sweat rate of the soccer players were observed as 0.5 % and 582.3 ± 232.0 mL/h, respectively. CONCLUSION: We found that youth soccer players are under a slight risk of dehydration under moderate weather conditions. As indicated by the research results, determination of hydration status of athletes must be taken into account more carefully under moderate and hot weather conditions. In addition, hydration methods were compatible with one another as measured in this study.

An evaluation of wheelchair basketball players' nutritional status and nutritional knowledge levels.

BACKGROUND: This study aimed to assess the nutritional status of women paralympic athletes and their nutritional knowledge. METHODS: Twenty two players of National Wheelchair Women Basketball Team (15-38 years) participated in this study and answered a questionnaire (76 questions) Players were at sport camp during the assessment where their body weight is measured regularly by the team coach. The waist, hip size and the height of the players who are able to stand have been used for the assessment, while the knee height of the players who are not able to stand have been measured for the study. SPSS 15.0 and BEBIS (Nutritional Data System) have been used for statistical assessment. RESULTS: The average age and sport years as a player of the participants are; respectively; 25.5±7.2 years and 3.9±2.8 years. The average daily energy consumption is 2867.8±523.6 kcal/day. The average proportion of energy, converted from carbohydrate, protein, fat are been calculated as, respectively; 42.7% (5.3±1.5 g/kg/day), 13.3% (1.6±0.3 g/kg/day), 44% (2.5±0.8 g/kg/day). It is also found that Vitamin B1, folic acid, magnesium, iron and fiber have not been consumed enough. The questions about sport nutrition have been mostly answered incorrectly. CONCLUSIONS: Athletes have inadequate food consumption and nutrition information. The athletes have to be educated more about nutrition and they should have nutritional counseling support.

Assessment of nutrition and life quality scores of individuals aged 65 and over from different socio-economic levels in Turkey.

Determination and assessment of nutritional status of elderly people is important to improve healthy living. The aim of the study was to determine the quality of life (QoL) and nutrition inadequacies of elderly people. For the nutrition risk scanning (NRS) including food consumption frequency with nutrition status of individuals above 65 years of age from different socio-economic status (SES), we selected 1060 elderly subjects. Of them, 400 (200 women, 200 men) are from low SES, 360 (180 women, 180 women) are from medium SES, and 300 (150 women, 150 women) are from upper SES. Their QoL scores were assessed according to the index of competence developed by Tokyo Metropolitan Institute of Gerontology (TMIG-IC). Parallel with the increase in SES, it has been found that scores of nutrition risk and capability index are increased and it is thought that this result is based on increased education status and pecuniary capabilities (p<0.05). Body mass index (BMI) (kg/m(2)) averages have been found as 29.3+/-4.9 kg/m(2) for women, and 26.9+/-4.0 kg/m(2) for men. It has been found that elderly individuals, at each of these three levels, consume milk and milk products at the recommended level (p>0.05), meat and meat products below the recommended level (p<0.05), fruit and vegetables at the recommended level (p<0.05). Lower SES consumes the cereals and cereal products the most. It has been found that daily liquid consumption (water, tea, fruit juice, and buttermilk) does not differ according to SES and is close to the recommended level (2300 ml/day).
