PubReader - OBJECTIVES
The purpose of this study was to compare the physical activity level (PAL), the physical activity pattern and the energy expenditure in male and female elementary school soccer players using the accelerometer and the physical activity diary.
METHODS
Twenty-five (male 11, female 14) elementary school soccer players (9–12 years) participated in this study. During their daily activities, they wore an accelerometer for seven days (five weekdays and two weekend days) and completed the physical activity diary for three days (two weekdays and one weekend day). PAL was calculated by using the physical activity diary and three equations (Pate Preschool, Freedson Children, and Freedson) were used to calculate the intensity of physical activity and energy expenditure from the counts of accelerometer.
RESULTS
The average of physical activity by day of the week, CPM (Counts Per Minute) and METs (Metabolic Equivalents) were significantly higher in males (723.3 ± 149.2 CPM, 2.07 ± 0.18 METs) compared to females (505.6 ± 119.9 CPM, 1.79 ± 0.20 METs), but there was no significant difference in PAEE (Physical Activity Energy Expenditure) between the two groups (males: 15.5 ± 9.1 kcal/day, females: 11.5 ± 6.0 kcal/day). During weekdays, physical activity intensity was significantly higher in males compared to females at lunch time and training time than at other times. In both genders, the PAL was higher during weekdays (males 1.98, females 1.89) compared to weekend (males 1.62, females 1.61) (p<0.05).
CONCLUSIONS
Our study observations suggest the necessity to develop an accelerometer equation for accurately evaluating the physical activity of elementary school athletes. -

Abstract

- This study was performed to compare food consumption patterns, dietary behavior, and nutrition knowledge between Korean professional soccer players and the non-athletic males. Data were collected from 53 soccer players working for Korean professional soccer clubs and 44 non-athletic males, using self-administered questionnaires. There were significant differences in food consumption frequency between two groups. Meats and eggs, fishes and shellfishes, sea weeds were consumed more frequently by the soccer players. The frequency scores of foods rich in iron, calcium, and protein were also higher in the soccer players compared with the non-athletes. Meanwhile, the consumption of alcohol was more frequent in the non-athletes. As for the cooking method, the soccer players showed higher preference for steaming/parboiling and consumed raw vegetables and fruits more frequently than the non-athletic males (p < 0.05). The average scores of soccer players on nutrition knowledge for basic nutrition and athletic nutrition were lower than the respective values of the non-athletic males. However, the soccer players showed better eating behaviors and dietary habits compared with non-athletic males (p < 0.001). They had well-balanced, regular diet and good habits for chronic disease prevention. No significant relationship could be observed with respect to nutrition knowledge and nutritional behavior. Moreover, the experience of getting nutrition information did not affect either nutrition knowledge score or nutritional habits score, except that for habits of chronic disease prevention in non-athletes. Therefore, it is suggested that more effective and practical nutrition education program be needed for promoting healthy eating habits and improving nutritional status in young males.
