Abstract

The study was designed to determine the relationship among iron status, energy and physical fitness levels of 20 female physical and health education students of Lagos State University aged 19 - 27±3.6 years purposely selected using a convenient sampling technique. A food survey questionnaire was used to record the food intake of the subjects for three days. To determine the percent fat of the subjects, three (3) skinfold thickness were taken at 3 different sites: triceps, thigh and subscapular and a formula for percent fat was applied. The height (cm) and weight (kg) were taken and were used to determine their Body Mass Index (BMI). Sample of blood was taken for biochemical analysis; 1ml blood sample was digested in the serum sample to determine the serum iron, while Coulter Counter machine was used to determine the full blood count. The fitness levels of the subject were determined using the Harvard step test. In order to determine the energy expenditure and balance, activity such as bench step was classified as heavy exercise. Data collected were subjected to descriptive statistics of mean, range and standard deviation while inferential statistics of Pearson's Product Moment Correlation Coefficient was used to test the hypotheses at 0.05 alpha level. The result revealed that there was a positive significant relationship among iron status and energy (r=1.00:p<.05), iron status and physical fitness levels (r=0.951:p<0.05) and physical fitness and energy expenditure (r=1.00:p<0.05) of female physical and health education students of Lagos State University. It was concluded that the subjects consumed less energy, had low iron status and low physical fitness level in spite of the fact that they are physical education student. There was significant correlation between serum ferritin and serum iron. This was because subjects who had high serum iron also had high serum ferritin levels, while those who had low serum iron had low serum ferritin. It was therefore recommended among others that young women should increase the intake of iron rich foods to improve their energy and iron levels.
