Objective PA will be measured through ActiGraph GT3X tri-axial accelerometers.
Because of the severe vibration during flight process, the elastic deformation caused by the weight of avionic devices which are placed in the head nacelle of the helicopter such as millimeter wave radar cannot be measured through the optical-imaging and accelerometer-induction method.
Measurements: Sedentary behaviors were measured through the use of daily activity logs, physical activity measured with accelerometers, and energy intake measured by means of repeated 24-hour recalls collected during each phase.
PA was measured with accelerometers.
Objective PA was measured with accelerometers.
Its mechanical response is measured with accelerometers.
Objective measures, such as sleep regularity measured by accelerometer data, may provide a more accurate understanding.
