Introduction. The development of the physical qualities of future architects is determined by the peculiarities of their professional activities. Static endurance helps to maintain a working posture while sitting and standing, bent at an angle of 30-45 ° for a long time, and overall endurance increases the resistance of the body and the efficiency of the specialist [1].
The purpose of the study is to identify the features of the development of endurance among architecture students during four years of study.
Methodology and organization of the study. Under supervision were students of the Faculty of Architecture and Urban Planning in the number of 125 people – 42 men (m) and 83 women (w). The volume of classes for 1-2 courses ‑ 4 hours a week, for 3-4 – 2 hours. The means used: ORU, cyclic exercises – long running at a speed of 6.54–8.71 km / h (m) and 5.87–7.17 km / h (w), special running exercises, acceleration. The severity of physical activity in terms of pulse rate (PE) is 140-160 beats/min. Criteria for assessing overall endurance in the 1st year – results in running 1000 m (m, w), strength endurance – "push‑ups" (m, w); in the 2nd–4th courses - in running 3000 m (m), 2000 m (w), "vis on a high crossbar" (m), "plank" (g). Adaptation and physical activity were controlled by reaction to a four-minute walk up and down the floors (N. M. Amosov, I. V. Muravov) with the calculation of emergency (ud/min), MP (kgm/kg), MPC (ml/min/kg). The functional state was determined by the Skibinskaya (IS) and Rufier (IR) indices.
The results of the study and their discussion. After two years of training, there is a significant increase in performance in running at 1000 m (m) – 3.12 ± 0.36 min, which is 33.2% higher than at admission. In women, the increase is 30.1%. Power parameters increased by 18.6% (m) and by 15.2% (w). At the 3rd‑4th courses, there is a decrease in all indicators to the initial level. The functional state remains stable and quite high: IS – 28.5–29.8 units, IR – 10 units in all courses, the score is "good" and "excellent". Moreover, the initial indicators of IS are 28.5 units (m) and 17.9 units. (g) indicate the beneficial effect of physical exercise on the body of students.
A four–minute ascent through the floors on each course is rated "good" and "excellent", reaching the indicators of MP – 24.5–25.2 kgm /min / kg, MPC - over 50 ml/min / kg, which characterizes adaptation to the intensity of physical exercises performed.
Conclusions. Exercises of a cyclical nature and strength orientation in the amount of 4 hours per week can develop and maintain at a sufficiently high level the physical qualities of "general" and "special endurance". Two hours a week and the lack of independent studies lead to a sharp decrease in endurance and, ultimately, can cause a drop in general and professional performance indicators.
