ACSM Northwest Webinar Series
The ACSM Northwest chapter is planning a series of free webinars for late 2019 and early 2020 leading up to our Annual Meeting in Boise, ID in February. You will find registration links to our upcoming webinar as well as information on future webinars.
Physiological Adaptations to Interval Training in Health and Disease
Dr. Martin Gibala- November 13th, 2019 at 10:00am PST
Interval training refers to an intermittent style of exercise in which repeated bouts are separated by recovery periods within a single training session. The last two decades have seen a resurgence of interest into the physiological responses to interval training and associated impacts on health indices. The method is infinitely variable, but can be broadly classified as either “aerobic”- or “resistance”-based, and further subdivided based on absolute or relative intensity. Most research has focused on an aerobic style commonly termed "high-intensity interval training" (HIIT), which generally refers to submaximal efforts that elicit at least ~80% of peak heart rate. HIIT induces physiological responses that resemble, and can be superior to, changes typically associated with traditional moderate-intensity continuous training (MICT), as reflected in public health guidelines. Systematic reviews and meta-analyses comparing MICT and HIIT, matched for total work or energy expenditure, have found that intermittent exercise elicits superior gains in cardiorespiratory fitness, and potentially other health-related indices such as glycemic control, depending on the characteristics of the participants studied. “Sprint interval training" (SIT) is a more intense version that involves ‘all out’ efforts or an intensity corresponding to ≥100% of the workload that elicits peak oxygen uptake. SIT has been shown to elicit physiological responses that are similar to MICT despite a much smaller total exercise volume and time commitment. This session will consider the physiological basis of responses to various types of interval training in both healthy and diseased states, and emerging research trends in the field.
Dr. Martin Gibala is a professor and chair of the Department of Kinesiology at McMaster University in Hamilton, Canada. He is an integrative physiologist who studies the mechanistic basis of exercise responses in humans, and associated health impacts. Gibala's research on the topic of interval training has helped to establish the efficacy of brief, vigorous exercise to enhance fitness in both healthy and diseased states. His knowledge translation efforts include a book for the general public on the science of time-efficient exercise, The One-Minute Workout: Science Shows a Way to Get Fit That’s Smarter, Faster, Shorter (Penguin Random House, 2017). Gibala has received three awards for teaching excellence at McMaster and the President’s Award for Excellence in Graduate Student Supervision.
Mobile Health Tools in Sedentary Behavior and Physical Activity Research
Dr. Dori Rosenberg- November 26th at 12:00pm PST
The presentation will discuss the use of various wearable devices in physical activity and sedentary behavior research. Several examples of research studies will be shared that have used wearable technology to assess and intervene on sedentary time and physical activity focusing on older populations and populations with chronic conditions. Challenges to using such technologies will be discussed.
Dori Rosenberg, PhD, MPH is an Associate Scientific Investigator at the Kaiser Permanente Washington Health Research Institute and is an Affiliate Associate Professor with the University of Washington, Department of Health Services. She has conducted extensive research on physical activity and sedentary time among older adults and populations with chronic conditions. She completed her PhD in clinical psychology & behavioral medicine at the University of California San Diego and San Diego State University. She is currently the principal investigator of the Healthy Aging Resources to Thrive (HART) Trial (R01 HL132880) where she is testing the efficacy of a sitting reduction intervention for older adults.
