17-18 metų rankininkų detreniruotumo kitimas treniruojantis septynias savaites mažesniu intensyvumu ir dešimt savaičių pasyviai ilsintis

ENThe purpose of this study was to determine peculiarities of detraining of 17–18 years old handball players after different activities during 17 weeks. One alternative experiment was applied. Subjects: 15 handball players of 17–18 years old from Olympic Sport Centre of Lithuania were observed (height 188,1±6,5; weight 84,6±17,8; BMI 23,3±1,2). Sport performance level of subjects was tested before experiment – after the main competitive season (on April), after 7 weeks low intensity trainings – before the transition period (on June), and after 10 weeks of passive rest – at the end of transition period (on August). After the finishing of the main competitive period, handball players had trainings for 7 weeks. There were 3–4 trainings per week. The training consisted of low intensity of endurance training, and the other sports games. They played several friendly handball matches. During the transition period players passively rested for 10 weeks (at the same time as studentÿs holiday). Physical and technical fitness was tested. During the last 7 weeks of competitive period were determined the significant decrease of aerobic endurance, speed-strength and strength-speed (p<0.05), but the technical indices remained the same or some of them slightly increased. An activity of specific training programme was the reason of unchanged technical fitness. During 10 weeks of transition period athletic and technical fitness decreased. 10 weeks of passive rest during transition period had the greatest influence on the changes on technical fitness of handball players aged 17-18 years while changes in physical fitness were of contradictory nature. Passive rest of 10 weeks had greater influence on decreasing of specific fitness of handball players. 7 weeks of competitive period with training programme of lower intensity helped to maintain technical fitness but not athletic of 17–18 years old handball players.The passive rest of 10 weeks had negative influence to detraining of 17–18 years old handball players and especially to technical and athletic fitness. Interaction between indices of technical and physical fitness before experiment after 7 weeks of low intensity of physical loads and after 10 weeks of passive rest were different. These findings allow to make statement that detraining of different indices of 17–18 aged handball athletes is dynamically individual. The changing of indices of some clusters not have any regularity and uniformity of changing indices of further clusters (Drinkwater, Horvath, 1972; Skarbalius, 2003; Skarbalius, Astrauskas, 2001; Svedenhag, 1992).
