Sleep variables were measured by seven days of wrist actigraphy along with sleep diaries. Self-reported physical activity and attitudes toward exercise were evaluated by questionnaires including the International Physical Activity Questionnaire.

　　用腕式睡眠活動記錄儀記錄了七天的睡眠情況，并做睡眠日記,。通過調(diào)查問卷方式,，包括通過國際體力活動的調(diào)查問卷，調(diào)查鍛煉身體和運動態(tài)度的自我評定情況,。

　　'This was a highly active sample averaging 83 minutes of vigorous activity per week,' said Glazer Baron.

　　“每周平均83分鐘的劇烈活動已經(jīng)屬于運動量很大的范例了,，”格雷澤·巴倫說。

　　'Even among those who were able to exercise, waking up late made it and being an evening person made it perceived as more difficult.'

　　“即使是能夠運動鍛煉的人,，晚睡晚起或久坐不動也會使得堅持運動成為一件很困難的事情,�,！�

　　According to Baron, the study suggests that circadian factors should be taken into consideration as part of exercise recommendations and interventions, especially for less active adults.

　　根據(jù)巴倫做的這項研究，建議應(yīng)考慮把生理因素視為運動鍛煉的一部分干預(yù)因素,，尤其是不運動的成人更要把這個因素考慮在內(nèi),。

　　'Sleep timing should be taken into account when discussing exercise participation,' she added.

　　“與參與運動鍛煉的人討論這個問題時，應(yīng)該考慮到睡眠時間這個因素,，”她補(bǔ)充道,。

　　'We could expect that sleep timing would play even a larger role in a population that had more difficulty exercising.'

　　“我們會認(rèn)為在夜貓子這類人群中，睡眠時間在其中起了比較大的作用,，堅持按時運動鍛煉就比較困難,。 ”

　　The Centers for Disease Control and Prevention recommends that adults get at last 150 minutes of moderate-intensity aerobic activity every week and participate in muscle-strengthening activities on two or more days a week.

　　美國疾病控制和預(yù)防中心建議:成人每周堅持做150分鐘中等強(qiáng)度的有氧運動，每周進(jìn)行兩天或兩天以上增強(qiáng)肌肉力量的運動,。（翻譯：Junjunmiao 滬江英語）
