The Physical Activity & Health Laboratory focuses on developing and examining technology-enhanced physical activity interventions to promote health,  cognition, and psychological well-being in school-aged children, young adults, and older adults. Our research examines the effects of (a) school-based physical  activity interventions on improving students’ motor skill competency, physical fitness, and physical activity behaviors; (b) different types of physical activities on improving the mental health and psychological well-being in college students; and (c) technology-enhanced two-level physical activity interventions on promoting functional fitness and psychological well-being in older adults living in retirement communities.
