Prediction of Energy Expenditure and Physical Activity in Preschoolers
ACCELEROMETER HEART RATE ACTIHEART ACTIGRAPH CALORIMETRY
2017/5/23
Accurate, nonintrusive, and feasible methods are needed to predict energy expenditure (EE) and physical activity (PA) levels in preschoolers. Herein, we validated cross-sectional time series (CSTS) an...
Effects of Altered Airway Function on Exercise Ventilation in Asthmatic Adults
AIRWAY CALIBER AIRWAY MECHANICS BRONCHOCONSTRICTION BRONCHODILATION EXERCISE-INDUCED BRONCHODILATION PULMONARY MECHANICS
2017/5/23
Variable airway function is a central feature of the asthmatic condition. Thus, habitually active asthmatics are certain to exercise under conditions of variable airway (dys)function. The purpose of t...
