Summary

The overall aim of this project is to investigate if the responsiveness to chronic resistance training is dependent on the muscle typology. In a second aim we will investigate the most optimal training frequency for slow-twitchers and fast-twitchers. For the latter we hypothesize that slow-twitchers might cope better with higher frequencies and higher volumes compared to fast-twitchers. Male and female adult participants (18-45y) will be recruited. The subjects' muscle typology will be non-invasively estimated in the leg muscles by measurement of muscle carnosine using H-MRS. In total 21 subjects (11 slow and 10 fast subjects) will participate. Subjects will be assigned to a whole-body resistance training exercise protocol of 9 weeks in wich arm A and leg A will train 3 times per week and arm B and leg B will train 2 times per week. Before and following the training period, subjects will be subjected to different measurements (fitness level, muscle volume, strength tests, blood sampling, muscle biopsies).
