Introduction. Effect of physical activity to people of various ages, proven by science research, leaves no doubt [1; 2]. Quite often too much desire to achieve expected result is observed. Overrating of physical capabilities not only gives no benefit but contrary – increases risk of injuries and health disorders [3]. The use of modern technology in order to record heart rate during physical activity allows to assess specifics of organism’s adaptation and the intensity of physical activity. Research aim. Determine young and middle – aged women heart rate dynamics during group aerobic training. Research methods and organization. Our study involved 20 women. Women were divided into two groups: the group of young women (n=12), age 21.7±1.6 years, and the group of middle – aged women (n=8), age 50±6.3 years. Young women BMI was 23.1±2.3 kg/m2, middle – aged women – 23.8±1.9 kg/m2. The participants were selected according to the criteria: not diagnosed with heart problems, positively assesses the state of one’s health and does not have serious complaints about their health, normal BMI (18.5- 24.9 kg/m2), attended aerobic workouts at least 6 months, attended to physical activity training at least 10 times, Physical Activity Readiness Questionnaire (PAR-Q) responses all negative. If at least one question is answered "yes", it is recommended to consult a doctor. Aerobic training were run two times a week, one hour each time. Training consisted of four phases: 1) the warm up (duration 10 min), 2) development of aerobic work (duration 30 min) 3) local individual muscle exercises (duration 10-15 min) 4) stretching, relaxation exercises (duration 5-10 min). During all workout, heart rate of each participant was measured using heart rate monitor "PolarH7", real-time data was being sent to software “Polar beat”. Heart rate was being observed during 15 workouts. The statistical analysis was executed usin[...].
