Role of change students'' residence during adaptation of their cardiovascular system to training conditions in high school
The role of change of students' residence in the adaptation of cardiovascular systems to training condition in high school is studied. Indicators of heart rate (HR) in both study groups were similar in their baseline values (73,06±5,36 and 71,60±8,64, respectively) and increased throughout the study (up to 84,94±9,5 at urban students and up to 84,93±8,35 - at visitors). Examination period is characterized by a marked increase in heart rate in a group of urban students (10,3%, from visitors - 5,9%), and at post-examinationtime prevailing intensity of regulatory mechanisms in visiting boys and girls on 18,6%, at urban - on 16,3%. Values of stress index (SI) in after examination period in the urbangroup (112,58±97,1), and in group of visiting students (87,53±83,1) increase from baseline inter-sessional period by 36,1% and 20,5%, respectively. In the post-session period not occurs restore the original states, in contrast, values of SI continue to increase in both groups (from baseline by 53,4% and 180,3%, respectively). Change of residence is a significant adaptogenic factors that impact on the process of adaptation to training in high school.
