简要总结
The effects of physical inactivity on variations in blood glucose and vascular health are not fully understood. The purpose of this study is to determine if an acute transition from physical activity to inactivity alters vascular health. Specifically, the investigators wish to examine in healthy, lean physically active individuals (obtaining greater than 10,000 steps/day) if decreasing physical activity (obtaining less than 5,000 steps/day) will alter blood flow following a meal a marker of vascular health. Furthermore, the investigators wish to examine if a one day return to physical activity (obtaining >10,000 steps/day) can restore the detrimental effects on blood flow following a meal.
详细描述
Herein, we tested the hypothesis that an acute reduction in daily activity (from \>10,000 to \<5,000 steps/day) for 5 days in healthy individuals reduced meal-stimulated blood flow and if a 1 day return to activity improved this outcomes.

Effects of Physical Inactivity on Post Prandial Blood Flow
时间窗: 10 days
There was a pre-measurement period of 3 days, then 5 days of inactivity, followed by 1.5-2 days of return to activity. A 10 day time frame overall. Blood flow measured by Doppler ultrasound during an oral glucose tolerance test before and after 5 days of inactivity.
