Measuring Children’s Physical Activity with Accelerometers and EMG – Dr. Ying Gao (Pt1)

Physical Activity Researcher

"Can we accurately measure children’s physical activity with just one device?"
In this insightful episode, Dr. Olli Tikkanen speaks with Dr. Ying Gao about her research on sedentary behavior and physical activity in children, combining accelerometer and EMG data to improve accuracy. Dr. Gao explains the challenges of using only accelerometers, as they capture movement but not muscle contractions, which are essential for understanding true physical activity. She describes her study on setting a reliable threshold to differentiate between sitting, light movement, and active play in children, aiming to create a standardized approach for assessing activity levels.

Dr. Gao also discusses her findings on how combining EMG with accelerometer data provides a clearer picture of muscle activity, especially for distinguishing between sedentary and active behaviors in school-aged children. This episode sheds light on new methods in physical activity measurement that could improve research on children’s health and activity habits.
