Diving and autonomic cardiovascular system regulation in persons with paraplegia
Journal Title: Rehabilitacja Medyczna - Year 2010, Vol 14, Issue 1
Abstract
Background: Diving has become popular among individualss with various kinds of disabilities and may be applied as a rehabilitation method. This form of activity has a beneficial effect on movement abilities and the psychological state. Some physical limitations disappear under water enabling disabled persons to discover new possibilities for their bodies. Yet there is not enough information - about the influence of diving on different aspects of physiology in disabled persons, in particular about sympathetic-parasympathetic balance in cardiovascular system regulation.Aim: To investigate whether diving can influence heart rate variability (HRV) in individuals with paraplegia.Material and methods: In the case series study 19 men with paraplegia were examined during the couse of two 20-minute, 6 meters deep open water dives in wet suits. There were two phases of the investigation: 10 minutes before and 10 minutes after diving. Two kinds of diving were tested: tourist and task diving. HRV parameters measured before and after diving were obtained by means of the sport-tester Polar Vantage .Results: There were no significant changes in heart rate variability after diving but interindividual differences were shown.Conclusions: The unfavourable influence of diving on balance in the autonomic regulation of the cardiovascular system was not confirmed but due to interindividual differences one is unable to foresee heart rate variability changes in persons with paraplegy during diving.
