Subject to the study were senior permanent residents of Yugra North (n=24 including 11 males and 13 females aged 68.2±5.6 years). The study was designed to analyze benefits of treadmill walking practices with paces varying within 2-7 km/h and stepped by 1 km/h. The oxygen demand (VO2 ml/min) rate, minute ventilation (Ve, l/min) rate, exhaled oxygen content (КО2, %) and heart rate (HR, beats per min) were obtained using FitmatePro Metabolograph system and a HR test system. The tests found the above rates growing with the growing pace (t test, p<0.05), with the only exclusion for КО2. We also found a close correlation of Ve with VO2 in the treadmill practices (r=0.86; p=0.0000) and HR (r=0.81; p=0.0000); and the finding gives the grounds to recommend equation VO2 = 81.7 + 29.3 Ve for the energy cost rating for the female group health improvement practices; and equation VO2 = -57.2 + 31.0 Ve for the male group health improvement practices. The regression equations factoring in the study data may be applied to control and manage physical loads in the health improvement practices in application to the senior residents of Yugra North. We recommend the lung ventilation being rated per 1 min by a dry spirometer followed by the rate being used to compute the oxygen demand rate using the above formulae.

Keywords: controlled walking practice, treadmill, HR, oxygen demand, lung ventilation, linear regression equation.
