Latent Hypertension and Dysautonomia Among Athletes With Office Prehypertension During One Year Training Macrocycle

Abstract

The research topicality is needed to diagnose in time and correct properly athletes’ autonomic dysfunction (especially among sportspeople with pre-pathological states). The study of latent hemodynamic changes and detection of dysautonomia among prehypertension athletes (particularly those who train heavily) is a promising way to raise sportsmen’s health and achievements. The research purpose is a hemodynamic profile study of athletes with office prehypertension during different training macrocycle periods. Methods. The research comprised 30 athletes of acyclic activity. Their average age was 23.1 (2.71) years. Females were nine individuals (30%). We monitored arterial blood pressure and heart rate in each macrocycle period, carried out the dysautonomia test and established anamnesis and complaints. Results. For prehypertension athletes, the most challenging moment was the competition period. Therefore, the systolic arterial hypertension rate within preparation, competitive and transition training periods was 17%, 47% and 7% (χ2=14.53; р0.001) while the diastolic one was 17%, 37% and 7% respectively (χ2=8.75; р=0.012). Significantly, we observed an increasing possibility of arterial blood pressure rise over normal values among dysautonomia athletes during the competition period (RR=3.27 (р=0.01); OR=8.33 (р=0.006)). However, during the preparation and recovery periods, arterial hypertension possibility was not significant (р0.05). Conclusions. In the competition period of training macrocycle is highly expectable development of arterial hypertension of latent course in athletes with office prehypertension. Besides, the relative risk of latent arterial hypertension in extra-training time increases if there are other symptoms of dysautonomia, but these changes are not persistent. However, their proper diagnosing and correcting may lead to athletes’ better health and achievements.
