| Abstract: The study investigated the "effect of moderate-intensity interval and continuous training on diastolic blood pressure and resting heart rate of overweight adults in Yenagoa, Bayelsa State." It was guided by two objectives, questions, and hypotheses. The study employed a "randomized pretest-posttest control group design." Pretests were administered to both experimental and control groups to measure diastolic blood pressure and resting heart rate. The experimental groups participated in a 12-week moderate-intensity interval and continuous training programme, while the control group did not receive any training. A posttest was conducted for all groups at the end of the intervention. The sample comprised 109 overweight adult volunteers (57 males and 52 females), randomly assigned to the experimental and control groups using the fishbowl method. Data collection instruments included a Stadiometer (SECA 217) and an Omron Karda Scan Body Composition Monitor (HBF-511), which are both standardized and validated tools. The reliability coefficient for resting heart rate and blood pressure measurements was r = .69 for males and r = .80 for females, respectively. Analysis was done using descriptive statistics for the research questions and ANCOVA for the null hypothesis at 0.05 alpha level, with the aid of SPSS version 26. Findings indicated that "both training protocols significantly influenced diastolic blood pressure and resting heart rate, with a small effect size." Thus, both moderate intensity interval and continuous training are effective in improving cardiovascular health among overweight adults. The study recommended the adoption of structured exercise programmes to manage cardiovascular risk factors in overweight populations. |
