Hypothesis. Heterochronicity of body functions reveals itself during the performing different movement tasks, in particular at onset of the exercise or in changing the parameters of the load as well as during the recovering period. We think that estimations of body functional state of the sportsmen can better reflect manifestations of complexity of body functioning during the physical loads tries join different movement tasks: a dosed aerobic load and a maximum effort anaerobic load try. In order to verify this hypothesis it is purposeful to estimate peculiarities of functional state change and long-term adaptation effects due to concentrated physical loads of different direction. The aim of the research: to define how the functional state of subjects adapted to speed-power physical loads is affected by concentrated aerobic and anaerobic type loads by using various assessments of sportsmen functional state. CONCLUSIONS 1. Subjects adapted to speed-power physical loads distinguish themselves by the higher indices of muscles working-capacity by performing maximum short-term effort requiring tasks than non-athletes or the subjects adapted to endurance physical loads. From the standpoint of central nervous system functional state indices they distinguish themselves by greater central nervous system mobility and smallest central nervous system functional stability values. Speed-power representatives distinguish themselves by lower cardiovascular system indices related to... [to full text]

The objective of this study was to determine sprint athletes and non–athletes girls acute muscles and heart adaptation peculiarities to multiple anaerobic loads. The study‘s participants were girls of similar age: 5 trained athletes in sprint events and 5 non–athletes. There were estimated their antropometric parametres, assessed body mass index (BMI) and heart rate at rest. Also participants performed multiple anaerobic workloads. The results of this research showed that girls well–trained athletes managed to perform greater extent of physical load, were less tired and managed faster to recover between reiterations. The non–athletes performed significantly lower extent of physical load and before the third workload their heart rate‘s indices and results of running 10 m distance with 10 % of body mass weighting indicated considerable fatigue. In consideration of long term adaptation effect we propose, that well–trained athletes have lower body mass, BMI, heart rate at rest, higher running velocity and greater increase of velocity compare to non–athletes. Eaqual duration, intensity, rest pauses and the number of reiterations with and without weighting have different effect on muscle working ability. Athletes showed greater running velocity and it remained unaltered during reiterations in performing eaqual workload without weighting. Participants reached lower velocity and there were obtained velocity reduction in performance with weighting.

Nustatyti intervalinio treniruotės metodu atliktų pratybų įtaką širdies funkcinių rodiklių kaitai atliekant dozuoto aerobinio krūvio mėginį. 4. Nustatyti intervalinio treniruotės metodu atliktų pratybų įtaką širdies funkcinių rodiklių kaitai atliekant dozuoto aerobinio ir maksimalaus anaerobinio krūvio mėginius. Tyrimo objektas: Raumenų ir širdies funkcinių rodiklių reakcija į intervaliniu treniruotės metodu atliktas pratybas. Tyrime dalyvavo dvylika vidutinio meistriškumo vidutinių nuotolių bėgikai (LSU studentai), kurie prieš intervalinio treniruotės metodu atliktu pratybų ir praėjus 15 min. po jų LSU Kineziologijos laboratorijoje dalyvavo fizinės ir funkcinės būklės vertinime. Šių vertinimų metu tiriamieji atliko vertikalius šuolių testus ant Tenzo plokštės: šuolis į aukštį pritūpiant 900 kampu, šuolis į aukštį iš fiksuotos 900 kampu padėties, šuolis į aukštį nuo 10 cm pakylos (Drop jump), taip pat Rufje fizinio krūvio mėginį (dozuoto fizinio krūvio mėginys), 30 s vertikalaus šuoliavimo testą ir po penkių minučių – dar kartą atliko Rufje mėginį.

The following tasks were set: 1- Determine the influence of anaerobic interval training session on the muscular performance during the vertical jump tasks. 2 – Compare the muscle work capacity after and before anaerobic interval training on 30 seconds vertical jump test. 3 – Determine the influence of anaerobic work-load on dynamics of cardiac indices while performing a dosed exercise test. 4 – Determine the influence of interval anaerobic training on cardiac indices while performing a dosed and maximal exercise tests. Methods. The study subjects were healthy and physical active students (men, n = 12). Before and after the anaerobic type training session performed by method of interval training were tested on physical and functional condition tests. To find out physical conditional were used vertical jump tasks. To asses the vertical jump the force plate with the jump height and take-off time measurer was used. Function condition tests were Roufier test and the 30 second vertical jump test, and after 5 minutes Roufier test was repeated. Main parameters of anaerobic interval training were 5x200m (28,0–29,0) [2:00] or some more repetition. The results obtained during the study showed that muscular changes can be described by registered parameters of vertical jumps indicating that the same result of the jump could be achieved by use if compensatory abilities, i...
