Mokslinių darbų, kuriuose būų nagrinėjami Lietuvos didelio meistriškumo vidutinių nuotolių bėgikių rengimo problemos yra labai mažai. Irina Krakoviak – daugkartinė Lietuvos čempionė, Pabaltijo mačų, Europos čempionatų dalyvė, pasaulio ��empionatų ir olimpinių žaidynių dalyvė. Ji yra viena pajėgiausių Lietuvos vidutinių nuotolių bėgikė. Šiame darbe analizuojami I. Krakoviak metinio treniruočių ciklo rengiantis pasaulio čempionatui Helsinkyje (2004 – 2005 metų sezonas), ir Europos čempionatui Gioteborge (2005 – 2006 metų sezonas) treniruočių metodika, krūvių kaita metiniame treniruočių cikle bei varžybų rezultatų dinamika. Darbo tikslas - Išanalizuoti Lietuvos vidutinių nuotolių bėgikės I. Krakoviak mėtinį treniruočių ciklą, jos rezultatus 2004 – 2005 ir 2005 – 2006 metų laikotarpiu. 2004 – 2005 ir 2005 – 2006 metų treniruočių cikle I. Krakoviak sportinę formą siekė įgyti du kartus – žiemą ir vasarą. Sportininkė 2004 – 2005 metų sezone dalyvavo Pasaulio čempionate 1500 m bėgimo distancijoje ir u��ėmė 11 vietą - 4.08,18 laikų. 2005 – 2006 metų sezone bėgikė dalyvavo Europos čempionate 1500 m bėgimo distancijoje įveikus šį nuotolį per 4.13,27 užėmė 27 vietą.. / There are not many paperworks analyzing problems of high class middle distance runners in Lithuania. Irina krakoviak is Lithuanian champion in women midle distance running championschip as well es participant in Balticstates, Europe and World running competitions. She is one at the most eksperieced middle distance athlets in Lithuania. This paperwork discloses problems which Irina Krakoviak has faced during preparation for world championchip in Helsinki and Europe championship in Goteborg. Paperwork discribes training methodology, exercises and table of resalts and achievements. The purpose of this work is to analize yearly trainingspecifications an cycle together with an analysis at result during 2004-2005 and 2005-2006 year. During 2004-2005 and 2005-2006 Irina Krakoviak was trying to get her athlets shape two times: one in winter season and one in summer season. An athlet took part in world chamionship ( 1500m distance group) and finished 11-th between other athlets (her result was 4.08.18). In 2005-2006 year she took part in Europe running championship. She finished 27-th (result was 4. 13.27).

Shortsea shipping promotion and optimization issues have been repeatedly emphasized by the EU Commission and long-term researchers of the segment. The problem we are facing today is, that many commercial players still wrongly approach shortsea shipping with scepticism, as a bit outdated mode of transport; besides there are numerous administrative obstacles and factors involved that impede ultimate integration of shortsea shipping into the existing intermodal and multimodal transport chains. Inadequate infrastructures of port terminals, lack of logistics elements, as well as protectionism related barriers existing in the EU member states, all these urge the necessity to investigate the feasibility and potential of shortsea shipping across the EU.

Pagrindiniai trys faktoriai lemiantys bėgikų ištvermę yra: maksimalus deguonies suvartojimas (MDS), laktato slenkstis (LS), bei bėgimo ekonomiškumas. Geriausi sportininkai turi panašų MDS, LS, bėgimo ekonomiškumą, bet įrodyta, kad raumenų faktoriai gali įtakoti ištvermę labiau, nei MDS. Yra duomenų, kad sportininkų raumenų galingumą įtakoja anaerobiniai adenozintrifosforo rūgšties (ATP) resintezės procesai, kurie gali turėti įtakos ir aerobinės ištvermės sportininkų varžybų rezultatams. Nustatyta, kad nuosekliai sunkėjančio krūvio (NSK) testo pabaigoje yra didesnis anaerobinis ATP resintezės indėlis. Vadinasi, didesnė raumenų masė ir jėga gali padėti toleruoti vis didėjantį ATP pareikalavimą ir parodyti didesnį deguonies suvartojimo pastovios fazės pasireiškimą. Labai įdomu būtų sužinoti, kaip anaerobinis pajėgumas gali įtakoti ilgų nuotolių bėgikų deguonies suvartojimo pastovios fazės trukmę. Mes manome, kad mūsų gauti tyrimo duomenys, leis geriau suprasti, kokį indėlį anaerobinis pajėgumas vaidina skirtingos deguonies suvartojimo pastovios fazės trukmės pasireiškime. Tyrimo tikslas – Nustatyti deguonies suvartojimą atliekant sunkėjantį krūvį ir pastovios fazės sąsaja su anaerobiniu pajėgumu. Tyrimo objektas: anaerobinio pajėgumo poveikis deguonies suvartojimo kaitai sunkėjančio krūvio metu. Tyrimo uždaviniai: 1. Palyginti aerobinio ir anaerobinio pajėgumo rodiklius tarp bėgikų pasiekiančių ilgesnę ir trumpesnę pastovią fazę. 2. Nustatyti koreliacinį ryšį tarp aerobinių ir...

The three main factors determining runners endurance are: maximum oxygen consumption, lactate threshold and running economy. However, among the best sportsmen of similar maximum oxygen uptake, lactate threshold and running economy has been shown that muscular factors may influence the endurance more than the maximum oxygen consumption. There is evidence that the athletes' muscle power affects the ATP resynthesis anaerobic processes that may affect the aerobic and endurance sports events. showed that a consistent worsening at the end of the test is more anaerobic ATP contribution resynthesis, thus more muscle mass and strength can help to tolerate the increasing demand of ATP longer a burden, and to show increased oxygen consumption in stable phase of occurrence. It is interesting to learn how to influence the anaerobic capacity for long-distance runners' oxygen consumption in stable phase duaration. Therefore, our survey data to obtain a better understanding of the contribution of anaerobic capacity plays a different oxygen consumption constant phase term occurs. The study objective – identify the oxygen uptake during increasing workload constant phase interface with the anaerobic capacity. The object of the study – anaerobic capacity effects on the oxygen consumption change during increasing exercise load. Study tasks: 1. To compare the aerobicand anaerobic capacity in...

There are few scientific studies, that research the problems of the high skills in the average distance runners training in Lithuania. M. Norbutas is a Lithuanian record - breaker in 800m distance running. And he was the first Lithuanian, who entered a contest in World Championship and the Olympic Games. M. Norbutas annual training cycle in the run – up to the World Championship in San Denis (the season of years 2002 – 2003) are analyzed in herein work. Also the training technique, the strain alternation in the annual training cycle and the dynamics of the contest score in the Athens Olympics (the season of years 2003 – 2004) are analyzed. And similarly, the best world runners of the average distance: the world record – breaker in 1500m distance running, the champion of Athens Olympics in 1500m and 5000m distance, the Maroccan H. El. Geurroj (preparation for the World Championship in 1997), the champion of Athens Olympics in 800m distance, the Russian Y. Borzakovskiy (preparation for the World Championship in closed accommodation in 2001), the Olympic champion of 1500m distance running in Barcelona and the European record – breaker, the Spaniard F. Cacho (preparation for the World Championship in Barcelona in 1992). The training techniques and the structure of micro cycles of those sportsmen are compared to the techniques of M. Norbutas. The physical development, the physical qualification, the functional alternation of a fitness rate in the run – up to the Olympic Games in... [to full text]
