概要 We examined the relationship between energy intake at breakfast and physical activity to determine the ideal breakfast size(in kcal) cross-sectionally. Twenty healthy student volunteers recruited. We analyzed 133 days dietary intake. Intensity of physical activity and step counts were measured with a Polar V800 accelerometer. When recorded activity was 2.0 METs (standing intensity)or higher, it was regarded as "active time". Active time and step count were significantly lower on days when breakfast was skipped than when it was not. Linear regression showed a significant positive correlation between energy intake at breakfast and active time. An inverted U-shaped quadratic curve was a better fit than a straight line. The resulting regression formula indicated that an energy intake of 526 kcal would yield the longest active time. Too little breakfast, as well as too much breakfast, can lead college students to be less physically active.
