Current or recently finished research projects as a PI or Co-PI
Academy of Finland 2014-2019 (publications until 2022). “Adequate muscle mass and aerobic capacity prolonging survival from muscle wasting: MassA”. I have been investigating the extent and mechanisms how adequate muscle mass and aerobic capacity can prolong survival from a catastrophe situation (muscle wasting). See publications: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13.
Muscle protein homeostasis: Proteostasis 2015-2020: This study investigated the effects of exercise, hypertrophy and atrophy on muscle protein homeostasis. See publications: 1, 2, 3, 4.
Fitness/physique sports and weight reduction 2015-. We study the effects of weight reduction on physiology and systems biology on fitness competitors. This study combines the skills from the experts of exercise and nutrition physiology, genetics, systems biology and sports psychology together. See publications: 1, 2, 3, 4, 5.
In vitro exercise 2019-. We investigate using e.g. C-Pace EPS system the effects of in vitro muscle contraction on muscle metabolism and "exerkines". See publications: 1.
Metabolic reprogramming in muscle atrophy and hypertrophy 2021-. This study investigates how parallel pathways to glycolysis are perhaps essential in maintaining or increasing muscle size in in vitro models.
Training, detraining and retraining in young individuals 2022-. We investigate physiological and molecular adaptations to resistance training, detraining and retraining when compared to control period and continuous resistance training.
