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<18.5 kg/m2).Over half the players were anaemic (Hb<120 g/L) and 25% were iron deficient (ferritin<15.00 µg/L). Dietary intake of iron was less than the Recommended Dietary Allowance (<18 mg/day) in 90%. Mean aerobic endurance (27.98±6.90 mL/min/kg) (maximal oxygen uptake, VO2 max) was very low. A moderate negative correlation (r=-0.672) (P<0.01) for BMI and a moderate positive correlation (r=+0.538) (P<0.01) for energy balance were observed for VO2 Max.

 

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.
