Differences in Health-related Fitness and Nutritional Intake in Collegiate Female Athletes

The purpose of the study was to determine differences in health-related fitness and nutrition intake by exercise type in collegiate female athletes. Thirty collegiate female athletes (10 for taekwondo, 10 for field hockey, and 10 for soccer) participated in this study. Mean ages for each group were 19.1 years for Taekwondo, 18.9 years for field hockey, and 20.6 years for soccer. Body weight and height were measured. Body composition parameters were determined by DXA (Hologic, QDR-4500, USA). Health-related fitness included sit and reach, grip strength, sit-ups, and cardio-respiratory endurance. Maximal heart rate and maximal oxygen consumption were assessed during incremental treadmill exercise using by a Bruce protocol. Nutrition intake was evaluated from three randomly assigned days of diet records, including one weekend day and two weekdays. From these records, average daily intakes of the nutrients were estimated using Computer Aided Nutritional Analysis Program (CANAP, Korean Nutrition Association). One-way ANOVA and Duncan's a posteriori tests were utilized to analyze the data. The significance level was set at p < .05. The results showed that significant differences could be obtained for lean tissue (F = 4.32, p < .02) and grip strength (F = 24.39, p < .0001) between groups. Field hockey athletes had significantly higher mean values for both lean tissue and grip strength than those of soccer athletes. With regard to the nutrition intake, there were significant difference for total calory intake, protein, fat, phosphorus, serum, and zinc between groups. Field hockey athletes had significantly higher mean values for total calory (2766.6 ± 566.32kcal), protein (103.8 ± 27.74g), fat (92.0 ± 33.81g), phosphorus ron (1301.8 ± 259.32mg) and zinc (13.1 ± 3.67 mg) than those of other two groups. In conclusion, collegiate female athletes from different sports had different lean tissue, grip strength, and nutrition intake.
