The development of the sprint events indoors has been studied, namely the 60 m, 200 m and 400 m dash. The analysis carried out has enabled us to formulate the following conclusions: 1. A wave-shape cyclic development has been displayed with alternating of results, which can be taken into consideration when defining the Bulgarian norms for participation in these European contests. 2. Indoor competitions are not always an object and aim in the training of the best European elite and that is the reason why prize placement with results lower than the norms may be possible.
