Rechnitzer Annual Lecture Series

Peter Rechnitzer, CCAA co-founder
The Rechnitzer Annual lecture is given by an invited speaker who is highly-regarded and recognized nationally and internationally for work in the areas of exercise, well-being and aging. The lecture also provides a platform for bringing together its invited speaker with CCAA’s Research Associates to promote scholarly dialogue and to explore research collaborations in the area of exercise, activity, health, well-being and aging. The lecture recognizes the outstanding contributions of CCAA co-founder Dr. Peter Rechnitzer.
About Peter A. Rechnitzer
Peter Rechnitzer was a practising physician who donated his efforts and expertise to combine research with practical application. He and Professor David Cunningham co-developed the idea for a research centre that focuses on physical activity in people ages 55 to 90 years. He enthusiastically joined with scientists, Professors Cunningham and Donald Paterson, and Nancy Ecclestone to develop the Centre for Activity and Aging.

Distinguished lecture in-person at Western
Speaker: Lora Giangregorio
Lora Giangregorio is a Professor and Tier 1 Canada Research Chair in Bone Health and Exercise Science Department of Kinesiology and Health Sciences. She received her doctorate at McMaster University. Her research interests include using medical imaging technologies to evaluate bone strength and muscle size and density in response to intervention after neurologic injury, evaluating the effects of interventions (e.g. exercise) for reducing fracture risk in high risk individuals, and knowledge translation.
Presentation Abstract
Fall-related injuries, including fractures, are the number one cause of hospitalization in older adults. Osteoporosis is a bone disease that results in low bone strength, and an increased risk of fractures. Balance, muscle strength, and bone strength decline with age, leading to an increased risk of falls and fall-related injuries, including fractures. Balance and functional training, with or without resistance training, can prevent falls. During this presentation you will learn about what osteoporosis is, and what clinical practice guidelines and other research says about the benefits and harms of balance and functional training, resistance training, and other types of exercise when it comes to fall and fracture prevention. The presentation will also include practical tips on participating in strength and balance training, including ideas for progressing your exercise program, or how to modify it for certain bone or joint concerns.
Webinar Recording & Slide Deck
Exercise for Osteoporosis & Fall Prevention
Lora Giangregorio, Professor and Tier 1 Canada Research Chair in Bone Health and Exercise Science at the University of Waterloo, presents on fall-related injuries—the leading cause of hospitalization in older adults. She will discuss how aging and osteoporosis increase fall and fracture risk, and what research says about the role of exercise in prevention. The session includes practical tips for safely progressing strength and balance training, even with bone or joint concerns.
