Coaches' perceptions about food, appetite, and nutrition of adolescent Indian athletes - A qualitative study.

Adolescence is a transitional phase of development with the risk of adopting unhealthy behaviours, which is carried on to adulthood. Adolescent athletes tend to resort to unhealthy eating habits resulting in eating disorders and other clinical outcomes. Hence, it forms a crucial age to understand modifiable food habits and provide appropriate counselling. In India, coaches closely monitor the adolescent athletes, even concerning their eating habits due to the lack of multi-disciplinary support staff. Thus, our study aimed to understand the perceptions of coaches towards food, appetite and nutrition of adolescent athletes using In-depth interviews (IDI). Of all 14 coaches at the state-sponsored residential sports centre, 10 consented. The IDI were conducted in a standardized manner and were recorded and transcribed. They were coded manually, using the open and axial coding in the grounded theory approach to determine themes. They considered nutrition as key to performance and consumption of higher animal protein as important. Majority of them considered sprouts, dry fruits, fruits and vegetables as healthy foods, though were unable to define the quantities nor nutrients therein. Coaches considered protein as "important", while fat as "unhealthy". They also observed that athletes were avoiding fruits and vegetables, while consuming more rice. Meal timing, fluid and supplement intake were considered essential for international performance, albeit unaware of the specific requirements. Hygiene practices and peer isolation were considered to affect food intake. This lacunae in the nutrition knowledge and the modifiable nutrition practices explored can be targeted by developing a nutrition education and assessment tool for coaches and junior athletes. Further, a long-term engagement of a nutritionist with every sports academy in India is recommended.

Energy Balance Coexists With Disproportionate Macronutrient Consumption Across Pretraining, During Training, and Posttraining Among Indian Junior Soccer Players.

PURPOSE: To evaluate energy expenditure, energy intake, and nutrient adequacy of Indian junior soccer players. METHOD: Forty junior national-level soccer players (Under-12 and Under-16 age groups) were assessed for 3-day weighed food records and 3-day energy expenditure. Energy and nutrient intake was analyzed from food records, and energy expenditure was measured using a portable metabolic analyzer and activity records. Nutrient adequacy was determined by comparing intake with prevailing recommendations. RESULTS: Players exhibited no significant difference between energy intake (boys = 3062 [340.9] and girls = 2243 [320.3] kcal·d-1) and expenditure (boys = 2875 [717.3] and girls = 2442 [350.3] kcal·d-1). Across age groups, the Under-12 boys showed positive energy balance as against energy deficits in Under-16. Girls showed energy deficits, although not significant. There were 58% of girls showing energy availability <30 kcal·kg-1 fat-free mass, of which 37% were Under-16 players. Carbohydrates contributed to >60% of energy expenditure among 95.2% boys and 73.7% girls. Among 52.4% boys and 47.4% girls, <25% of energy expenditure was contributed by fat. More than 95% players consumed <1 g·kg-1 carbohydrates pretraining and 100% of them consumed >1.2 g·kg-1 carbohydrates posttraining. CONCLUSION: Junior soccer players consumed more than recommended carbohydrates in the diet, although not aligning with the pretraining, during training, and posttraining meal requirements. Considering the energy deficits observed among Under-16 players, a suitable dietary modification is warranted.

Resting metabolic rate of Indian Junior Soccer players: Testing agreement between measured versus selected predictive equations.

OBJECTIVES: Owing to a dearth of research related to Resting Metabolic Rate (RMR) among adolescent athletes in India, our study aimed to document RMR among junior soccer players (JSP) and to identify suitable RMR predictive models for JSP from nine existing equations. METHODS: Forty Indian JSP (Boys = 21, Girls = 19) representing the under-12 and under-16 age categories were assessed for body composition (skinfold technique) and RMR (oxycon mobile). Two-way ANOVA and ANCOVA were used to examine the differences across age and sex. Bland-Altman plot was used to test agreement between measured vs. predicted RMR using the equations of Cunningham (, The American Journal of Clinical Nutrition, 33), Soares et al. (, European Journal of Clinical Nutrition, 47; 1998, British Journal of Nutrition, 79), Henry (, Public Health Nutrition, 8), and Patil and Bharadwaj (, Journal of Postgraduate Medicine, 59) for non-athletic populations and the equations of De Lorenzo et al. (, The Journal of Sports Medicine and Physical Fitness, 39), Wong et al. (, Singapore Medical Journal, 53), and ten Haaf & Weijs (, PloS One, 9) for adult athletes. RESULTS: RMR showed significant (P < .01) sex differences (Boys: 1343 ± 297.1; Girls: 1135 ± 116.7 kcal·day-1 ). While RMR values adjusted for fat-free mass (FFM) were similar across age and sex. The equation of Soares et al. (, British Journal of Nutrition, 79) for girls and Wong et al. (, Singapore Medical Journal, 53) for boys showed better RMR predictability. CONCLUSIONS: FFM explained variation in RMR across age and sex. The FFM-based Soares et al. (, British Journal of Nutrition, 79) equation for girls and body weight-based Wong et al. (, Singapore Medical Journal, 53) equation for boys are best suited for predicting RMR.
