The validity and inter-device variability of the Apple Watch™ for measuring maximal heart rate (2017)
Journal Article
Abt, G., Bray, J., & Benson, A. C. (2018). The validity and inter-device variability of the Apple Watch™ for measuring maximal heart rate. Journal of sports sciences, 36(13), 1447-1452. https://doi.org/10.1080/02640414.2017.1397282

Maximal heart rate (HRmax) is a fundamental measure used in exercise prescription. The Apple Watch measures heart rate yet the validity and inter-device variability of the device for measuring HRmax are unknown. Fifteen participants completed a maxim...

Quantifying the external and internal loads of professional rugby league training modes : consideration for concurrent field-based training prescription (2017)
Journal Article
Weaving, D., Jones, B., Till, K., Marshall, P., Earle, K., & Abt, G. (2020). Quantifying the external and internal loads of professional rugby league training modes : consideration for concurrent field-based training prescription. Journal of strength and conditioning research, 34(12), 3514-3522. https://doi.org/10.1519/JSC.0000000000002242

The intermittent movement, collision and skill components of professional rugby league match play require players to have a wide range of physical (e.g. repeated effort ability, speed) and technical qualities (e.g. passing, kicking, tackling ability)...

Multiple measures are needed to quantify training loads in professional rugby league (2017)
Journal Article
Weaving, D., Jones, B., Marshall, P., Till, K., & Abt, G. (2017). Multiple measures are needed to quantify training loads in professional rugby league. International journal of sports medicine, 38(10), 735-740. https://doi.org/10.1055/s-0043-114007

To investigate the effect of training mode (conditioning and skills) on multivariate training load relationships in professional rugby league via principal component analysis. Four measures of training load (internal: heart rate exertion index, sessi... Read More about Multiple measures are needed to quantify training loads in professional rugby league.

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., Carroll, S., Ingle, L., & 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. https://doi.org/10.1055/s-0043-120195

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...
