Coupling heart rate and power data in professional road cycling: Shorter heart rate response indicate better 10-min time trial power output. Journal of Sports Sciences, 43(10), 978-985.
The aim of our study is to investigate whether coupling power output (PO) and heart rate (HR) data of semi-professional road cyclists collected in the field is helpful for optimising the training process.

To extract, prioritize, and model the highly conserved variations in mean-maximal power (MMP) data in cyclists utilizing functional principal component (FPC) analysis.
Mulligan, M., Adam, G., & Emig, T. (2018). A minimal power model for human running performance. PloS one, 13(11), e0206645.
Models for human running performances of various complexities and underlying principles have been proposed, often combining data from world record performances and bio-energetic facts of human physiology. The purpose of this work is to develop a novel, minimal and universal model for human running performance that employs a relative metabolic power scale.
