Abstract: Nuo atsigavimo ypatumų ir trukmės priklauso kito fizinio krūvio poveikis organizmui ir superkompensacijos treniruojamasis poveikis. Tikslas – įvertinti ištvermės šakų sportininkų arterinio kraujo spaudimo (AKS) ir arterinio kraujo kitimus blauzdos raumenyse nustatant didžiausią pėdos lenkiamųjų raumenų jėgą. Tyrimuose dalyvavo 17 prie ištvermės fizinių krūvių adaptuotų sportininkų. Po 20 min adaptacijos būnant ramiai buvo matuojamas AKS ir arterinis kraujo kiekis blauzdos raumenyse. Įvertinus AKS ir arterinio kraujo kiekį buvo atliekami trys maksimaliosios valingos jėgos (MVJ) matavimai. Po kiekvieno jėgos nustatymo buvo matuojami AKS ir arterinio kraujo kiekis. [...]
The peculiarities and duration of recovery determine other physical loads’ influence on organism and supercompensation training effect. The study aim is to assess endurance athletes’ arterial pressure and arterial blood variations in the calf muscles during maximal foot flexor muscles strength. Seventeen middle and long distance runners took part in our research. After 20 minutes’ adaptation period in sitting position, measurement the arterial blood pressure (ABP) and calf muscles blood flow intensity was performed using the method of venous occlusive plethysmography. After ABP and blood flow measurement three tests of maximal voluntary strength (MVS) were performed. After every strength measurement ABP and arterial blood flow intensity are tested. After three measurements, the MVS of the foot flexor of the endurance athletes did not differ much statistically (p>0,05). Systolic ABP in the condition of rest was 121,6±2,2 mm Hg. After the first physical loads it changed in the following way: 130,0±2,2 mm Hg (p0,05), and after 150 s it decreased in comparison with the initial level– 120,5±2,2 mm Hg (p0,05), whereas after the 150-th s–73,1±2,3 mm Hg (p>0,05). After the second and the third MVS measurement diastolic ABP changed analogically the first strength test. Arterial blood flow in the condition of rest was– 4,3±0,2 ml/min/100 ml. Immediately after the first measurement, maximal blood flow intensity can be noticed – 25,7±2,3 ml/ min/100 ml (p0,05); after the 77th, 106th, 141st, and 167th seconds blood flow intensity is lower than before physical loads in the condition of rest. After the second and third MVS measurement arterial blood flow intensity changed like after the first strength test. ABP (systolic and diastolic), are significantly higher one minute after the strength measurements if compared with those in the condition of rest. Arterial blood flow intensity is the highest after physical loads, and later after work hyperemia its intensity gradually decreases, as already during the 53rd s of recording, blood flow intensity nearly achieves initial level, and during the 77th s blood flow in many cases is significantly lower the initial level in comparison with the condition of rest.
