We may prefer exercising at certain temperatures, but does ambient temperature actually affect our performance? And if so, is there a difference between men and women? Created by Stephen Cheung, Ph.D., Director of the Environmental Ergonomics Lab and Professor at Brock University ( EELBrock). Papers discussed: Sandsund M et al. Effect of ambient temperature on endurance performance w...

Cold exposure leads to a higher metabolic rate to increase heat production. Does your level of body fat change the amount of metabolic rate increase that is possible? Created by Stephen Cheung, Ph.D., Director of the Environmental Ergonomics Lab and Professor at Brock University ( EELBrock). Papers discussed: Brychta RJ et al. Quantification of the capacity for cold-induced thermogen...

Cold injuries to the hands and feet can be debilitating for workers, soldiers, and others in cold environments. Is it possible to predict who may be at greatest risk? Does your cold tolerance improve over time? Created by Stephen Cheung, Ph.D., Director of the Environmental Ergonomics Lab and Professor at Brock University ( EELBrock). Papers discussed: Brändström H, H Grip, P Hallber...

Weight cutting is often done by combat sport athletes before competitions in order to compete at a lighter weight category. But can too rapid and too much weight cutting impair strength, balance, or power, all essential factors for success? Created by Stephen Cheung, Ph.D., Director of the Environmental Ergonomics Lab and Professor at Brock University ( EELBrock). Papers discussed: M...

Regular moderate exercise can provide many health benefits. Can it help to reduce the risk of death during spikes in air pollution? Created by Stephen Cheung, Ph.D., Director of the Environmental Ergonomics Lab, Department of Kinesiology, Brock University ( EELBrock). Paper discussed: Wong CM et al. Does regular exercise protect against air pollution-related mortality? Preventative M...

Virtual ICEE Webinar Season 3 discussion on hypoxia and its impact on cognitive performance. 5:16 Dr. Joe Costello (U Portsmouth, UK) discusses his research on hypoxia and cognition. 31:00 Dr. Kate O'Keeffe (U College Dublin, Ireland) discusses her research on the role of psychological factors on cognition in hypoxia.

Heat adaptation can be critical for athletic success, but might it slow down our response to training and our long-term fitness gains? Created by Stephen Cheung, Ph.D., Director of the Environmental Ergonomics Lab, Department of Kinesiology, Brock University ( EELBrock). Paper discussed: Slivka D, R Shute, W Hailes, K Marshall, M Opichka, H Schnitzler, B Ruby. Exercise in the heat bl...

Early human migration into Europe date to about 500,000-350,000 years ago, before evidence for the invention of fire. Could these early humans survive in these northern regions year-round without fire for heating? Created by Stephen Cheung, Ph.D., Director of the Environmental Ergonomics Lab and Professor at Brock University ( EELBrock). Papers discussed: Shivering in the Pleistocene...

Exertional heat stress (EHS) can be a big danger for soldiers, workers, and athletes. With advances in wearables technology, can core temperature and balance measures help to predict who's at risk for EHS BEFORE it happens? Created by Stephen Cheung, Ph.D., Director of the Environmental Ergonomics Lab and Professor at Brock University ( EELBrock). Papers discussed: Buller M et al. Ga...

In 2020, the CORE temperature monitor was introduced to major publicity, and it has been adopted by many cycling teams and triathletes as a way to non-invasively measure deep body temperature. However, it was introduced into the market without any independent testing of its validity or reliability - until now. Created by Stephen Cheung, Ph.D., Director of the Environmental Ergonomics Lab and Pr...

Virtual ICEE Webinar Season 3 Episode 3. Co-organizer Professor Stephen S Cheung from Brock University surveys 4 topics in cold physiology research: 1. Does hypothermia actually impair exercise capacity? 2. What is the metabolic fuel source for shivering? 3. Are there sex differences in cold response? 4. Can beetroot juice and exogenous nitrates improve hand and finger tolerance to cold?

Manual dexterity is critical to our survival, and it gets reduced greatly when our hands or cold and wet. Is that impairment due to cold or moisture, or both? Created by Stephen Cheung, Ph.D., Director of the Environmental Ergonomics Lab and Professor at Brock University ( EELBrock). Papers discussed: Ray M, E Sanli, R Brown, KA Ennis, H Carnahan. The combined effect of cold and mois...
