Low dietary intakes, BMI, iron and aerobic endurance among Sri Lankan professional female Hockey players

Abstract

Background: Compromised micronutrient or energy intake can influence body composition which could affect aerobic endurance of athletes potentially resulting in poor sports performance. Objective: To study the nutritional status, nutritional intake and aerobic endurance, and to identify potential associations between these parameters in Sri Lankan professional female hockey players. Methods: Professional, female hockey players (n=31) were recruited exclusively from professional clubs and the national team. Pretested questionnaires were administered to assess sport specific data and dietary intake. BMI, haemoglobin, serum ferritin and aerobic endurance were assessed. Results: Total energy intake from the diet was less than the individual specific requirement in 52%. Less diversity in carbohydrate intake observed (approximately 1/3 of total energy intake and 1/2 of the carbohydrates, is from rice). Twenty nine per cent were under weight (BMI Conclusion: Inadequate and less diverse dietary intakes, low BMI and iron deficiency were observed in this cohort of professional hockey players. Observed low aerobic endurance levels in these athletes is a concern for performance and the nutritional factors that coexist may have played a part. Education on the concept of optimum nutrition for performance in these individuals is warranted.
