Aspartame in conjunction with carbohydrate reduces insulin levels during endurance exercise (2012)
Journal Article
Siegler, J., Howell, K., Vince, R., Bray, J., Towlson, C., Peart, D., …Atkin, S. (2012). Aspartame in conjunction with carbohydrate reduces insulin levels during endurance exercise. Journal of the International Society of Sports Nutrition, 9, https://doi.org/10.1186/1550-2783-9-36

Background: As most sport drinks contain some form of non-nutritive sweetener (e.g. aspartame), and with the variation in blood glucose regulation and insulin secretion reportedly associated with aspartame, a further understanding of the effects on i...

Exercise-induced dehydration with and without environmental heat stress results in increased oxidative stress (2011)
Journal Article
Hillman, A. R., Vince, R. V., Taylor, L., McNaughton, L., Mitchell, N., & Siegler, J. (2011). Exercise-induced dehydration with and without environmental heat stress results in increased oxidative stress. Applied Physiology, Nutrition, and Metabolism, 36(5), (698-706). doi:10.1139/h11-080. ISSN 1715-5312

While in vitro work has revealed that dehydration and hyperthermia can elicit increased cellular and oxidative stress, in vivo research linking dehydration, hyperthermia, and oxidative stress is limited. The purpose of this study was to investigate t... Read More about Exercise-induced dehydration with and without environmental heat stress results in increased oxidative stress.

The effects of a constant sprint-to-rest ratio and recovery mode on repeated sprint performance (2011)
Journal Article
Abt, G., Siegler, J. C., Akubat, I., & Castagna, C. (2011). The effects of a constant sprint-to-rest ratio and recovery mode on repeated sprint performance. Journal of strength and conditioning research, 25(6), 1695-1702. doi:10.1519/JSC.0b013e3181dbdc06

It is unclear if a constant sprint-to-rest ratio allows full performance recovery between repeated sprints over different distances. This is important for the development of sprint-training programs. Additionally, there is conflicting evidence on whe... Read More about The effects of a constant sprint-to-rest ratio and recovery mode on repeated sprint performance.
