Aims and objectives: Hypertension remains a significant risk factor in cardiovascular morbidity and mortality. The purpose of the present study was to investigate the effects of 8 weeks interval training programme on blood pressure, aerobic capacity (VO max), indices of adiposity and marker of inflammation in black African men with essential hypertension. Patients and methods: Two hundred and forty five (245) male subjects with stage 1 and 2 (systolic blood pressure [SBP] between 140-179 & diastolic blood pressure [DBP] between 90-109 mmHg) essential hypertension were age matched and grouped into experimental and control groups. The experimental (n=140; 58.90 ± 7.35 years) group involved in an 8 weeks interval training (60-79% HRmax) programme of between 45 and 60 minutes, while age-matched control hypertensive (n=105; 58.27± 6.24 years) group remain sedentary during this period. All subjects in both groups were on antihypertensive drugs throughout the study period. Cardiovascular parameters (SBP, DBP) & VO max and percent body fat [%BF], waist to hip ratio [WHR] and C-reactive protein [CRP] were assessed. Independent t-test and Pearson correlation test were used in data analysis. Results: Findings of the study revealed significant decreased effects of interval training programme on SBP, DBP, %BF, WHR and CRP and significant increased effect on VO max at p< 0.05. Also, changes in CRP as a result of exercise training significantly and positively correlated with changes in SBP, DBP, %BF, WHR, CRP and negatively correlated with VO max at p< 0.05 Conclusion: It was concluded that interval exercise training is an effective adjunct in the management of essential hypertension.
