In this article the author gave an abstract of his study concerning a research the aim of which was to find the answer to the question whether it is more advantageous to train the more difficult gymnastic movements in a concentrated way in successive P. T. lessons, or whether it is preferable to train them in lessons separated by an interval of certain length. By his research the author aimed at finding out the significance of the time factor in the proce'ss of the initial training of gymnastic skills in order that any possible gain of time resulting from a more economical time-table of training might be used for a better fulfilment of the tasks of physical training in our schools.
This research proved by means of pedagogical methods that a concentrated time-table of training led the pupils, especially the least gifted and the backward ones to achieve a higher quality of gymnastic skills than a staggered timetable, and it also aroused greater attention and interest of pupils in the exercises. The concentrated time-table of training in the gymnastics of pupils of the medium age group proved to be the most suitable and efficient. The degree of concentration which brought the best results was found to be everyday training, for teachers and pupils achieved relatively the best results while exerting the least effort. Everyday training created conditions for shortening the total amount of time necessary for the training to a minimum, which is of considerable importance from the point of view of didactic economy.
The general comparison method, applied in experimental teaching in the form of an experimental and control team with parallel classes, and in a pedagogical experiment in the form of homogenous groups, brought positive results.
In conclusion of his article the author states that it is necessary to investigate the problem further from the point of view of specificity of the other most important branches of P. T. and to further develop the applied methods of research .and make them more accurate.
