Characteristics of hemodynamic and psycho-emotional state indicators among women aged 25-30 years in the process of step-aerobics
When assessing the correspondence of the level of physical activity to the functional capabilities of the body, the choice of criteria that most adequately reflects the state of functional systems is of great importance. The purpose of the study was to assess the state of hemodynamics and psycho-emotional state among women 25-30 years age in the process of doing step aerobics in combination with stretching. The study involved 20 women aged 25-30 years old. Within 12 weeks, classes were held in health-improving physical culture by using step aerobics and stretching. For the subjects there were indicated the heart rate, stroke and minute volume of blood circulation, cardiac index, systolic, diastolic, pulse rate, mean arterial pressure, coefficient endurance according to the Kvass formula, blood circulation efficiency coefficient, Robinson coefficient, as well as an assessment of the psycho-emotional state. A decrease in the ability to adapt in women 25-30 years old in terms of hemodynamics was revealed: the stroke and minute volume of blood circulation were reduced by 33.6% and 12.8%, respectively, compared with the lower limit of normal. The values of systolic and diastolic blood pressure, on the contrary, corresponded to the upper limit of the norm. The minute volume of blood circulation, mean arterial pressure and Robinson coefficient were higher than normal by 12.7%, 17.7% and 8.0%, respectively, which indicates fatigue. After 12 weeks of training, the values of the most indicators corresponded to normal, stroke and minute volume of blood circulation indicators significantly increased by 1.2 times, a decrease in coefficient endurance by 1.3 times was noted. The values of the studied indices for well-being, activity and mood increased by 1.26, 1.16 and 1.23 times, respectively. Controlling the compliance of loads with the functional capabilities of the body based on a wide range of hemodynamic parameters will allow you to maximize the individualization of fitness programs for middle-aged women.
