EFFICIENCY INCREASING OF NORDIC WALKING CLASSES AMONG OLDER WOMEN THROUGH FUNCTIONAL TESTING

Vishnevskij Vladimir Antonovitch

The reaction of the cardiorespiratory system of the elderly women organism to the functional tests of Nordic walking on a treadmill with a closed power cycle has been studied, using the mobile systems «COSMEDK5» and "GuarkT12x". For analyzing the data a hysteresis loop was constructed, reflecting the dependence of the indicators on the load capacity, with the load phase angles evaluation (α), the load downward phase (β) and the hysteresis loop area (S). Based on the results of the tests, individualization of Nordic walking classes was carried out using both straight-line and variable methods and speed-strength training. The advantages of the experimental group were identified according to the growth of heart rate (αHR), oxygen pulse (αVO2/HR), respiratory quotient (αRQ) with increased load, pulse load cost (BPHR), physiological costs on load with respiratory quotient (BPQ), reduced oxygen consumption (VO2) at resting, at the pinnacle of the standard load and immediately after it ends.
