Background. Studies investigating the relationship between exercise and haemodynamic regulation conducted in older caucasian and blackAfrican populations suggest that lifestyle modification is effective in the management of numerous disease processes. There are few longtermstudies in young healthy populations and even less is known about the influence of habitual exercise on autonomic and haemodynamicvariables in young black African subjects.Objective. To investigate the benefit of prolonged exercise on cardiovascular and haemodynamic variables in young healthy black African males.Methods. Fifty-five healthy male volunteers between 18 and 22 years of age participated in this prospective 20-week medium- to highintensityexercise intervention study with a self-control design. The Finometer Pro (Finapres Medical Systems, the Netherlands) was usedfor non-invasive data sampling of a number of cardiovascular and autonomic variables. Results were generated by computer algorithm andwere analysed using non-parametric Wilcoxon signed rank tests.Results. Significant (p 0.05).Conclusion. The measured changes suggest a favourable response to exercise and imply that habitual exercise may be an important lifestylemodification for reducing the risk of cardiovascular disease in young black African males.
