Night owls may be more sedentary, less motivated to exercise

04.06.2014

Later sleep timing is associated with greater sedentary minutes and perceived barriers to exercise

A new study suggests that night owls are more sedentary and feel that they have a harder time maintaining an exercise schedule.

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.

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.

"We found that even among healthy, active individuals, sleep timing and circadian preference are related to activity patterns and attitudes toward physical activity," said principal investigator Kelly Glazer Baron, PhD, associate professor of neurology and director of the Behavioral Sleep Medicine Program at the Feinberg School of Medicine at Northwestern University in Chicago, Illinois. "Waking up late and being an evening person were related to more time spent sitting, particularly on weekends and with difficulty making time to exercise."

The research abstract was published recently in an online supplement of the journal Sleep, and will be presented Wednesday, June 4, in Minneapolis, Minnesota, at SLEEP 2014, the 28th annual meeting of the Associated Professional Sleep Societies LLC.

The study group comprised 123 healthy adults with a self-reported sleep duration of at least 6.5 hours. 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.

"This was a highly active sample averaging 83 minutes of vigorous activity per week," said Glazer Baron. "Even among those who were able to exercise, waking up late made it and being an evening person made it perceived as more difficult."

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.

"Sleep timing should be taken into account when discussing exercise participation," she added. "We could expect that sleep timing would play even a larger role in a population that had more difficulty exercising."

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.

Im Focus: The pyrenoid is a carbon-fixing liquid droplet

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Im Focus: Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.

The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
