Slavic nations are celebrating 150 years of Sokol gymnastics in their countries. The first Sokol club started in Praque in 1862 and more about Czech and Slovak gymnastics you can find in the first article written by well known Professor Ph.D Anton Gajdoš with Maria Provaznikova. It is worth to note another Anton Gajdoš idea of preparing National encyklopedy of Sport in Slovakia - from 1840 till present time www .sportency .sk. The second article is from Myrian Nunomura (Brazila); Yoshinori Okade (Japan); Paulo Carrara(Brazilia) and covers very interesting topics - how much coaches know about gymnasts motivation, or better where is their lack of knowledge. The third article comes from United Kingdom. Authors Fernanda Faggiani, Allistair P. McRobert and Zoe Knowles prepared article with title Developing pre-performance routines for acrobatic gymnastics: A case study with a youth tumbling gymnast, it is the first article dealing with acrobatics, but their experience can be used in any gymnastics sport. The Greek authors Proios Miltiadis, Mavrovouniotis Fotios, and Proios Michalis are rounding psychological topics in this issue with review article titled Propolsal of psychological preparation in artistic gymnastics. Important topics for coaches to what they should be also focused beside the technical training. The fifth article is from Croatia young researcher Mateja Kunješic, she was researching what are parents expectations for their children exercising gymnastics. It is worth to note, despite injuries in high performance gymnastics, the main reason is child health, competitions are not important by itself and even more surprisingly, there is no differences between mothers and fathers. The last article comes from Tunisians Bessem Mkaouer, Samiha Amara and Zouhair Tabka. They made a biomechanical analysis of split leap with and without ball throw-catch. With task to throw and catch the ball the biomechanic parameters of split leap change significantly. It is a matter of motor control and article brings us inside of which parameters we are changing to catch ball. I wish you pleasant reading and a lot of inspiration, for preparing new researches and articles, Ivan Čuk Editor-in-Chief 3
