Abstract
The impact of dietary modification and nutrition
education on athletic performance was studied. This study
was done on thirty adolescent athletes (13-14 years of
age) from Boys Sports Company, Artillery Centre, Hyderabad
where talented children are given extensive sports
training.
The dietary pattern, nutritional status and
nutritional knowledge of these athletes were assesed.
The diet of the athletes had iron, carotene, B-complex
vitamins and ascorbic acid below the RDA. The calories
from fat and protein was within the.RDA limit but that of
carbohydrates was marginally low. The ·calcium and
phosphorus intakes · exceeded the RDA. These intakes
reflected in the nutritional status. Sixty three per cent
had mild malnutrition as per BMI and 70 per cent had mild
iron deficiency with mean haemoglobin level of 11.36 g/dl.
All the athletes scored below 40 per cent in nutrition
knowledge pretest on total score of 65 with mean score of
26 per cent. However the knowledge in the area of sports
nutrition was higher (49%) than general nutrition (17%)
during pre test.

daily. Dietary modification was introduced and implemented
along with nutrition education for a period of 60 days.
A significant improvement in the nutritional
status of the subjects was observed with 53 per cent ,
achieving normal BMI, due to increase in weight by 4 kg
during the study period. The lower body weight observed
in the beginning of the study resulted in low energy
expenditure, BMR and energy cost during stepping exercise
which increased after the weight gain. Sixty per cent
subjects achieved normal haemoglobin level, the mean level
being 12.35 g/dl. This reflected on the heart rates, with
13-15 per cent increment in work efficiency while in basal
h~art rate there was five per cent increment.
In post nutrition knowledge test 80 per cent
scored above 60 per cent with mean 69 per cent. There was
increase in both sports and general nutrition knowledge.
Nutrition knowledge ~as negatively correlated · with fat
content (P<0.01) ·systolic pressure (P<0.05), basal heart
rate, energy expenditure, energy cost during stepping
exercise and positively correlated with energy intake.
