Adolescent sleep patterns are often measured with self-report ( Lewandowski, Toliver-Sokol, & Palermo, 2011 ) or actigraphy ( Galland et al., 2018 ). Although self-report is easier to administer, lower in cost, and requires less technical expertise than actigraphy, it is often affected by social

( Koltyn, 2002 ; Mathesom et al., 2013 ). One method that may be beneficial in altering lifestyle habits and health behaviors is through the utilization of wearable technology. When measuring activity levels, this technology is referred to as actigraphy, which is used to objectively measure physical

collegiate soccer players (8.00 AM vs 8.00 PM). They observed while the player’s chronotype did not influence actigraphy-based sleep quality in response to a morning HIIT session it did have a significant effect on sleep parameters in response to the evening session. The morning-type (M-type) subjects

We, therefore, tested if the timing of meals, light exposure, physical activity, and sleep were associated with body mass index (BMI) in a sample of healthy adults who recorded the timing of behaviors over multiple days using a novel smartphone application and actigraphy. We first

Critically, due to the mismatch between subjective and objective measures of sleep quality in both phases, actigraphy should be used to evaluate sleep in athlete populations. The shorter sleep
