Dr. Klentrou is an exercise physiologist who uses applied and basic science approaches to study human performance and health implications of sport training in children and youth. Supported by NSERC, CIHR and various sports agencies, her current research is trying to identify the cellular mechanisms that explain how exercise and diet affect bone development and lifelong bone health. With >120 publicationsDr. Klentrou is a leader in her field, and involved with many health and sports organizations including Osteoporosis Canada, and the International Gymnastics Federation.
