People who consider themselves to be “owls” tend to sit more instead of exercise, and are generally less motivated to stick to a training plan compared to “larks”.
This is stated by researchers participating in the Behavioral Sleep Medicine Program at the Feinberg School of Medicine at Northwestern University in Chicago.
The results of a new study were presented in the journal Sleep..
For the first time, scientists presented their data in Minneapolis, where the 28th annual meeting of the Association of Professional Societies for the Study of Sleep was held the other day..
The U.S. Centers for Disease Control and Prevention recommends that adults sleep at least 7-8 hours a day. Lack of sleep can affect a person’s ability to fight chronic diseases, including diabetes, depression, obesity, and cardiovascular disease..
The study included 123 healthy adult volunteers who reported sleeping at least 6.5 hours a day. Carpal actigraphy and sleep diaries for 7 days were used by scientists to measure the variability of sleep patterns in a group. Participants filled out questionnaires, including the questionnaire for physical activity (International Physical Activity Questionnaire), where they themselves talked about the physical exercises performed..
“It was a very active sample of participants, with an average of 83 minutes of intense physical activity per week. For those who were physically involved, getting late to bed and getting up late (a typical “owl” regimen) posed certain difficulties, ”writes lead researcher Dr. Kelly Glazer Baron, professor of neurology and director of the Behavioral Sleep Medicine Program.
The results of the latest study show that those people who later go to bed, by their own admission, spend more time instead of doing physical exercises. Thus, sleep patterns can be considered a factor that affects physical activity..
The author of the study explained: “We found that even among healthy, physically active individuals, falling asleep is associated with activity patterns and the effectiveness of physical activity. Late awakenings are associated with longer sitting and lack of adequate physical activity during the day, especially when it comes to weekends ”.
Participants who referred to themselves as “owls” more often described their lifestyle as sedentary and found more reasons not to exercise, citing, for example, lack of time for classes or inability to follow a training plan.
The study suggests that circadian factors should be considered in adult exercise guidelines..
“Sleep time should be taken into account when you are discussing a person’s participation in a training program.. We believe that sleep is especially important for those who are engaged in more intense workouts, ”the scientists concluded.
US CDC recalls that physical activity helps improve overall health and reduces the risk of many chronic diseases.
CDC experts recommend that all adults engage in medium-intensity aerobic exercise of at least 150 minutes a week, and give muscle strengthening exercises 2 days a week.
In February 2014, Medical News Today published a report on another study conducted by Northwestern University of Chicago.. Then scientists found that sitting too long is the main risk factor for disability in people over 60. The researchers concluded that for an older person every extra hour a day spent on the couch is a doubled risk of disability in the future.
