The authors give necessary and sufficient conditions for the existence of trapped surfaces in spherically symmetric initial data sets. The conditions they obtain show explicitly that the formation of trapped surfaces depends on the degree of concentration and on the average flow of matter. Thus they give an explicit realisation of the so-called 'trapped surface conjecture'.
