Abstract

Objective: The aim of this study was to determine the effect of continuous training program on the correlates of white blood cell count (WBCc) and psychosocial stress in black African (Nigerian) male subjects with essential hypertension.

Two hundred and seventeen subjects with stage 1 and 2 [systolic blood pressure (SBP) between 140 and 180 and diastolic blood pressure (DBP) between 90 and 109 mmHg) hypertension were age matched and randomly grouped into continuous (112) and control groups (105). The continuous group involved in an 8 weeks continuous training (60-79% HR max) of between 45 and 60 minutes, three times per week, while the controls group remain sedentary. Blood pressure (SBP and DBP), WBCc, VO 2 max and psychosocial status were assessed. Student t test and Pearson correlation test were used in data analysis. Results: The study revealed significant beneficial effect of continuous training programs on VO 2 max, SBP, DBP, WBCc and psychosocial status (P Conclusion: This study supports the recommendations of moderate intensity (continuous) training program as an adjunct multi-therapy in blood pressure, inflammatory, and psychosocial stress management in hypertension.
