囧研究：夜猫子不爱运动是有原因的

Why night owls shun exercise: Waking up late 'makes it harder to keep a fitness regime'
夜猫子不运动是有原因的：晚睡晚起很难做到坚持“健身”

Late sleepers more sedentary and find it harder to exercise, study found.
研究表明，晚睡的人都有久坐不动的习惯，很难坚持运动。

Night owls also make up more reasons not to be active.
夜猫子们也为自己不运动找了很多理由。

Adults should take 150 minutes of moderate-intensity exercise a week.
成人每周应做150分钟中等强度的运动。

Night owls who wake up late are less likely to take exercise.
夜猫子们起床晚，坚持运动锻炼的可能性也就很小了。

Latest research suggests night owls are more sedentary and feel that they have a harder time maintaining an exercise schedule.
最新研究结果表明，夜猫子久坐不动的生活方式，使他们在坚持锻炼健身计划上就变得比较困难。

Results show that later sleep times were associated with more self-reported minutes sitting, and sleep timing remained a significant predictor of sedentary minutes after controlling for age and sleep duration.
研究结果表明，晚睡次数和他们自己记录的久坐时间有关系，同时在控制年龄和睡眠持续时间等因素后，发现睡眠时间可以极大程度地推算久坐不动时间。

However, people who characterized themselves as night owls reported more sitting time and more perceived barriers to exercise, including not having enough time for exercise and being unable to stick to an exercise schedule regardless of what time they actually went to bed or woke up.
不过，那些自称夜猫子的人，说自己坐着的时间比较长，认为自己在运动上有各种障碍，包括没有时间运动，而且无法坚持按照健身时间表进行运动锻炼，实际上他们并没有考虑自己的上床睡觉时间或起床时间。
