EI grupė dirbo pagal fizinės saviugdos skatinimo programą, kurioje daugiau dėmesio buvo skiriama aerobiniam pajėgumui ugdyti (greitumui - 20%, jėgai - 20%, aerobinei ištvermei - 40%, kitoms fizinėms ypatybėms - 20%). E 2 gnipė dirbo pagal fizinės saviugdos programą, kurioje daugiau dėmesio buvo skiriama jėgai ir greitumui ugdyti (greitumui - 30%, jėgai - 30%, aerobinei ištvermei - 20%, kitoms fizinėms ypatybėms - 20%). E4 grupė dirbo pagal fizinės saviugdos skatinimo programą, kurioje buvo numatyta tolygiai ugdyti visas fizines ypatybes. E3 ir E 5 grupės lankė tik akademines kūno kultūros pratybas. Darbe taikyti tyrimo metodai: 1. Literatūros šaltinių analizė. 2. Pedagoginis ugdomasis tyrimas. 3. Anaerobinio glikolitinio pajėgumo (AGP) nustatymas panaudojant 1 min maksimalaus intensyvumo darbą veloeigometni (Szogy, Cherebetin, 1974). 4. Matematinės statistikos analizė. Tyrimų rezultatai ir išvados. Nustatyta, kad Vilniaus pedagoginio universiteto pirmo kurso studentų (n = 105) vidutinis anaerobinio glikolitinio darbo pajėgumas yra 360,1 ±4,33 W, po 1 min maksimalaus fizinio krūvio pulsas per tris minutes nuo 184,5±0,96 tv./min suretėja iki 130,3±l,17 tv./min. Pritaikius fizinės saviugdos skatinimo sistemą, eksperimentinių grupių studentų anaerobinis glikolitinis pajėgumas turėjo tendenciją gerėti, tačiau patikimai (p <0,005) gerėjo tik E4 grupės studentų anaerobinioglikolitiniopajėgumo rodikliai. E3 irE5grupių studentų anaerobinisglikolitinispajėgumas kito labai nedaug, todėl galime teigti, kad darbas pagal fizinės saviugdos skatinimo sistemą gerina studentų anaerobinį glikolitinį pajėgumą. Eksperimentinių grupių studentų atsigavimas (pagalpulso dažnį) po 1 min maksimalaus fizinio krūvio turėjo tendenciją gerėti, tačiau tik E4 grupės studentų atsigavimas per tris minutes pakito palikimai (p < 0,005). Kontrolinių grupių studentų atsigavimas po 1 min maksimalaus fizinio krūvio kito nedaug, todėl galime teigti, kad darbas pagal fizinės saviugdos skatinimo sistemą turėjo teigiamą poveikį studentų organizmo galimybei greičiau atsigauti po fizinių krūvių. Didžiausią poveikį studentų anaerobiniam glikolitiniam pajėgumui ir atsigavimui po 1 min fizinio krūvio turėjo fizinis darbas, kuomet visos fizinės ypatybės buvo ugdomos tolygiai, mažiausią - kuomet buvo akcentuojamas greitumo ir jėgos ugdymas.

Specific qualities of competitive performance observed in different sports demand that athletes demonstrate definite special characteristics. Training and competitive performance provokes different adaptive changes within athletes' organisms. There are some sports giving preference to tall athletes. However in the greater part of sports, remarkable results may be achieved also by medium-height or even short athletes. To compare the specific influence produced by separate sports on athletes' organisms, it would be necessary to choose study groups involving athletes similar in terms of height characteristics. Study purpose was to examine specific characteristics of physical development, physical skills, and definite functions demonstrated by high performance athletes, very similar in their body height yet very different in terms of performed sport activity; and to carry out a corresponding comparative analysis. Our study involved 48 high performance athletes practising different sports. All of them were either member candidates or full members of Lithuanian Olympic Team: kayakers and canoeists (k/c) (n=12); - skiers and biathlonists (n=12); cyclists (n=12); and master team football players (n=12).). There was determined that body height and most other indices of physical development and capacity demonstrated by Lithuanian high performance athletes practising different sports differ slightly. It was only kayakers and canoeists who surpassed others in their body built and muscle power which allowed them to get among the leading athletes of the world. It was found that athletes' muscle mass was closely related to SMCP, AAMP, and high jump indices. Development of the mass of special muscles is one of the vital factors for the improvement of muscle power at short work. The study revealed problems existing in the area of selection and training of Lithuanian high performance athletes. This information may help elaborate further training of athletes...

Such correlation was found also in athletes from other sport disciplines (Pečiukonienė, Dadelienė, 2003; Платонов, 2004). SMCP, AAMP, 10-s and 30-s special performance indices were closely related among themselves and with muscular mass. The results suggest that the ability of cyclists to perform in various events is strongly predetermined by genetic factors and particularly by a rapid and slow fibres ratio in the muscles. This correlation is reliably reflected by SMCP indices (Bosco et al., 1983). The test could be useful in selecting cyclists' specialization. The PRT and 10-s MF indices showed no functional ties with special anaerobic alactic and combined anerobic alactic glycolytic capacity. These tests may reflect the CNS condition, but not muscular power.

The aim of this study was to investigate the young athletes' nutrition planning according to the concept of adequate nutrition and formula of balanced nutrition taking into consideration athletes' canteen menus and their variations. For the investigation, athletes' canteen menus of the different seasons of years 2005-2006 were selected. From each seasonÿs every month, there were chosen 6-day menus with 4-day intervals (72 menus in total). The obtained data was compared to chemical composition of athletes' canteen menus of the year 1989. After carrying out comparative analysis of the menus, the variations of nutrition in athletes' canteen were assessed. The study results showed that the total energy quantity of athletes' canteen menu rations of the years 2005/2006 cover athletes' energy inputs. The mean energy value of rations equals 4882,63 ± 57,90 ccal (S = 127,34). Just slight variations where found following evaluation of the mean energy value of different season menus. Winter season menus had the highest energy value – 5044,83 ± 64,28 ccal (S = 276,40), while for the spring season, it was the lowest – 4726,4 ± 75,40 ccal (S = 324,21). However, the difference was statistically insignificant (p>0,05). Athletes canteen menus of the years 2005/2006 meet their energy requirements. On the other hand, the nutrition balance is reflected at best by the percentage of energy value supplied with proteins, fat and carbohydrates.

Another division of respondents was based on gender difference, i.e. the fourth group (E4) included 13 - 14 year old track & field female athletes, the fifth group (E5) - 13 - 14 year old male athletes, the sixth group (E6) - 15 - 17 year old female athletes, the seventh group (E7) - 15 - 17 year old male athletes. It has been proved that there were many factors, which influenced preference for track & field, for example, socializing with other athletes, coach, travel (54,4%); interest to cross-fertilize knowledge, gain practical activity skills (49,5%); build up self confidence (32,2%); invitation by a coach (48,6%); recommendation by a teacher of physical education (42,6%); parental influence (26,2%). Motivation for training is very much influenced by an interest to seek for better sport results (83,7%), to participate in sports events (73,3%), to become healthy and strong (74,1%), to become a member of a National Team (62,7%), to become an Olympian (58,3%). The minimal motivation for training is associated with material benefits (18,3%) as well as a wish to become a recognized and honourable person (30,0%).

The food provided in athletes canteen only partially covers energy expenditure of athletes, depending on the age, sex, sport discipline, height and weight. So it is very important to estimate the athlete’s satisfaction with the canteen’s nourishment, evaluating the amount of the provided food in relation with hunger, appearing three hours after eating, also with the energy value of the provided food, depending on athletes’ nutrition schedule, in order to ascertain the objective groups, which have major connection with the risk of inadequate, unsuitable and unbalanced nutrition. The aim of this study is to evaluate the athletes’ satisfaction with the nutrition planning. The investigation have been performed during the year 2007. The investigation involved 50 athletes of Lithuanian Olympic Sport Centre selected randomly and eating in athletes’ canteen every day. In this study anonymous questionnaire method was used. Athletes’ satisfaction with the canteen’s nutrition of Lithuanian Olympic Sport Centre was investigated by this method. The data of the research was evaluated distributing respondents by age, sex, height, weight and sport discipline. The SPSS version 13,0 analytical software was used for the analysis of the research data. The data are statistically correct if the probability of bias is (p<0,05). Statistic relation is evaluated by Chi square parameter (χ2 ). The investigation showed that these athletes, who do not eat or eat very rarely their breakfast food portion, feel more hungry three hours after eating. Food amount receivable during the dinner is inadequate for athletes of track-and-field athletics and contemporary pentathlon, who are 18 – 20 years old, weigh 82 – 110 kg and 182 – 204 height. With the growth of age, height and especially weight the amount of food obtainable in the canteen is too small.[...]

The programme of swimming is very broad and includes different swimming styles as well as distances. Such a variety determines different methodological approaches to training and conditions various adaptive changes in the body. The aim of the work is to investigate the change in the physical development, physical capacity and functional capacity of high performance young brass swimmer, Lithuanian swimming record-holder, world youth championship prizeman and a member of Lithuanian Olympic team over the four-year Olympic cycle and to compare the acquired indices with the statistical indicators of the Lithuanian national team. The sample of the research included one high performance athlete specialising in brass swimming. The indicators of his physical development and anaerobic alactic muscular capacity in the four-year Olympic cycle were established. Special physical anaerobic glycolytic capacity was investigated applying special ergometer for handwork of swimmers at 60 s maximum work. The functional capacity of circulatory system was also measured. During the four-year Olympic cycle considerable changes were observed in the majority of physical development indices: the height of the athlete rose by 4.5 cm, the body mass increased for account of muscle mass growth (5.7 kg), whereas the fat mass remained almost the same. The hand power and ventilation lung capacity went up significantly. The indices of single muscle capacity and anaerobic alactic muscle capacity changed slightly. As they were relatively high, it was concluded that that fast fibres prevail in the athlete’s muscle structure. The indicators reflecting the level of glycolytic capacities and acquired during the special 60 s hand work capacity test were improving considerably (from 203 to 272 W) and the work endurance parameters demonstrated a considerable increase.[...]
