Research Interests

My main research interest lies in the field of muscle architecture and function. This interest mainly evolved during a project in my bachelors (Human Movement Sciences, VU, 2008-2010) a fellow student and I were challenged to investigate jumping performance in marmosets (small monkeys). During the MOVE research masters this project continued and finally let to my first real scientific contribution in 2014.  In the final year of my masters under the supervision of dr. R.T. Jaspers we investigated architectural changes of the medial gastrocnemius during adolescence with a novel 3D ultrasound technique. We found that longitudinal growth of the medial gastrocnemius muscle belly in boys between 10-19 years is predominantly mediated by increases in the length component of the physiological cross-sectional area. I’ve presented the outcome of this study at both the ECSS in Amsterdam (2014) and the WCB in Boston (2014).

Medial gastrocnemius muscle growth during adolescence is mediated by an increase of fascicle diameter rather than by longitudinal fascicle growth.
