Karin Allor Pfeiffer is a professor and director of the Institute for the Study of Youth Sports at Michigan State University. She also is a member of the Center for Physical Activity and Health. Pfeiffer is an exercise physiologist with an interest in population-based investigations. Her research focuses on two major areas, both of which are related to physical activity in children and adolescents. Her work spans the age range of preschool through high school (and even addresses college students sometimes). The first major area of research is measurement of physical activity, which she has been investigating since graduate school. The second major area is interventions to increase physical activity, which she has been investigating since her post-doctoral research position at the University of South Carolina. She has been involved with many school-based studies and is interested in incorporating families and communities into her research. She has also been at the forefront of work examining physical activity in preschool children and plans to continue more research in that area.
