Dr. Moritz Schumann is a post-doctoral researcher at the Department of Molecular and Cellular Sports Medicine, German Sport University, Cologne. He received his PhD focusing on physiological adaptations to various training modes of concurrent endurance and strength training from the Department of Biology of Physical Activity, University of Jyvskyl (Finland). Dr. Schumann has published numerous international scientific articles discussing methods to optimize concurrent endurance and strength training for both untrained populations and endurance athletes. He was the coordinator of an International Symposium organized in Finland in the Fall of 2015, which entirely focused on the topic of the book. Furthermore, he has given several presentations for sport and exercise scientists, students and practitioners promoting various aspects of concurrent training. Currently Dr.

Schumann is working in a large network of international experts to further scientifically explore the methodological challenges of combined aerobic and strength training, especially for clinical populations. Prof. Dr. Bent R Rnnestad is a professor at the Section for Sport Science, Lillehammer University College (Norway) and a consultant for The Norwegian Olympic Federation, providing physiological research and supervision for the Norwegian elite coaches and athletes in endurance and team sports. He received his PhD from the Norwegian School of Sports Sciences where he was focusing on the effect of concurrent endurance and strength training on cycling performance in well-trained cyclists. Prof. Rnnestad has published a large number of international scientific articles focusing on the effects of concurrent strength and endurance training on elite sport performance in road cycling, cross-country skiing and endurance running. He has also been an invited speaker on various topics of concurrent training at both international and national conferences and symposiums.

Therefore, Prof. Rnnestad is part of a large network of international experts which helps to scientifically explore the methodological challenges of combined aerobic and strength training, especially for well-trained populations.
