Validity and reliability of the Apple Watch for measuring heart rate during exercise (2017)
Journal Article
Khushhal, A., Nichols, S., Evans, W., Gleadall-Siddall, D., Page, R., O'Doherty, A. F., …Abt, G. (2017). Validity and reliability of the Apple Watch for measuring heart rate during exercise. SMIO / Sports Medicine International Open, 1(6), (E206-E211). doi:10.1055/s-0043-120195. ISSN 2367-1890

We examined the validity and reliability of the Apple Watch heart rate sensor during and in recovery from exercise. Twenty-one males completed treadmill exercise while wearing two Apple Watches (left and right wrists) and a Polar S810i monitor (crite... Read More

Effectiveness of short-term heat acclimation on intermittent exercise in thermoneutral and hot environments (2015)
Journal Article
Nation, F., Birkett, M., Gleadall-Siddall, D., Burke, R., Towlson, C., Bray, J., …Garrett, A. (2015). Effectiveness of short-term heat acclimation on intermittent exercise in thermoneutral and hot environments. Extreme Physiology and Medicine, 4(1), A120. doi:10.1186/2046-7648-4-S1-A120

It is well-established that repetition of heat stress exposure has been shown to facilitate adaptations to the heat but these protocols have tended to be of a fixed work intensity, continuous exercise, long-term in duration (>7 days) and use hydratio... Read More

Cardiometabolic health benefits of a six-week high-intensity interval training intervention : a case study (2014)
Journal Article
Siddall-Gleadall, D., Gritt, J., Burke, R., O'Carroll, G., Bray, J., Ingle, L., & Garrett, A. (2014). Cardiometabolic health benefits of a six-week high-intensity interval training intervention : a case study. Journal of sports sciences, 32(Supplement 2), s28-s32. doi:10.1080/02640414.2014.968381

Regular physical activity is recommended for patients diagnosed with impaired glucose tolerance (IGT) and Type 2 Diabetes. However, "lack of time" is a common cited barrier in achieving the recommended weekly physical activity guidelines. High-intens... Read More

Effectiveness of a six-week high-intensity interval training programme on cardiometabolic markers in sedentary males (2014)
Conference Proceeding
Gleadall-Siddall, D., Burke, R., Gritt, J., O'Carroll, G., Bray, J., Ingle, L., & Garrett, A. (2014). Effectiveness of a six-week high-intensity interval training programme on cardiometabolic markers in sedentary males. doi:10.1080/02640414.2014.968390

High-intensity interval training (HIT) has been proposed as an effective, time efficient strategy to elicit similar cardiometabolic health benefits as traditional moderate-intensity endurance training. This is an important consideration as "lack of t... Read More
