Whilst working at Al Ahli Saudi FC, Jan van Winckel asked me whether I would like to participate with his book Fitness in Soccer. So we wrote the following chapter together with:
McMillan, K., VanWinckel, J., Seerden, G. & Helsen, W. High-intensity interval training (with special reference to Small-Sided Games). In van Winckel et al. (2014). Fitness in Soccer: the science and practical application. (pp. 83-108).
