CHANGE IN THE FUNCTIONAL STATUS OF EXTREME ATHLETES IN RESPONSE TO ADVERSE ENVIRONMENTAL CONDITIONS

Keywords: heart rate variability, functional status, type of regulation, athletes, adaptation

Abstract

Aim: the authors aim to develop criteria for assessing the functional status of extreme athletes in response to adverse environmental conditions by using the data obtained from the circulatory and autonomic nervous systems. Materials and methods: the study included 60 extreme athletes (mean age 25.1 ± 3.1 years). Heart rate variability (HRV) measurements were performed with the Varicard 2.51 system and used for assessing the functional status of athletes. The statistical analysis was performed with STATISTICA 7.0 software. Results: based on HRV data, it was demonstrated that heart rate (HR), mean and maximum RR intervals (Mean RR and XMax), the percentage of successive RR intervals that differed by more than 50 ms (pNN50), the mode (Mo), the amplitude of the mode (AMo50), and the stress index (Si) of the regulatory systems could be used for assessing the functional status of extreme athletes in response to adverse environmental conditions (p < 0.001). Conclusions: dynamic HRV monitoring in extreme athletes allowed for the assessment of the functional status of extreme athletes by using the following parameters: HR, AMo50, Si, Mean RR, XMax, pNN, and Mo. The authors developed significant (p < 0.001) team criteria, which had strong positive and negative correlations (r > 0.70; r > –0.70) with the functional status of extreme athletes.
