Introduction. Prehypertension is a precursor for developing hypertension and is a risk factor for cardiovascular diseases. Yoga therapy may have a role in lowering the blood pressures in prehypertension and hypertension. This systematic review aims to synthesize the available literature for the same. Methodology. Databases such as PubMed, Embase, Scopus, and Web of Science were searched for randomised control trials only in the time duration of 2010–2021. The main outcome of interest was systolic and diastolic blood pressures. Articles were screened based on the inclusion criteria, and 8 articles were recruited for the review. Meta-analysis was done for suitable articles. RevMan 5.4 by Cochrane was used for meta-analysis and forest plot construction. Risk of bias was determined using the Downs and Black checklist by three independent authors. Results. The meta-analysis of the articles favoured yoga intervention over the control intervention. Yoga therapy had significantly reduced the systolic pressure (−0.62 standard mean difference, at IV fixed 95% CI: −0.83, −0.41) and diastolic pressure (−0.81 standard mean difference, at IV random 95% CI: −1.39, −0.22). Secondary outcome measures studied were heart rate, weight, BMI, waist circumference, and lipid profile. The main protocol of yoga therapy included postures, breathing exercises, and different meditation techniques. A significant reduction in secondary outcomes was observed, except for HDL values in lipid profile which showed a gradual increase in yoga group in comparison with alternative therapy. Conclusion. Yoga therapy has shown to be significant in the reduction of systolic and diastolic pressure in prehypertensive population. Supporting evidence lacks in providing a proper structured dosage of yoga asanas and breathing techniques. Considering the existing literature and evidence, Yoga therapy can be used and recommended in prehypertensive population and can be beneficial in reducing the chances of developing hypertension or cardiovascular diseases.

Background: Physical Inactivity (PI) and sedentary behaviour are the most important and modifiable risk factors to prevent cardiovascular diseases (CVD). Cardiac rehabilitation (CR) is a multidisciplinary program for patients who have undergone cardiac surgeries. Through CR, monitoring physical activity (PA) is possible and may reduce the rate of rehospitalization. The pedometer is a device that is useful to track the step count of the person day to day. It helps in self-monitoring of PA. The purpose of this review was to summarise the evidence about the effect of pedometer-based exercise program in phase 1 and phase 2 CR. Methods: Databases such as MEDLINE, Cochrane, Scopus, Embase, and Web of Science were searched. This search is limited to randomized controlled trials (RCTs), human trials, a 10-year period, and English language journals. Based on inclusion criteria of pedometer-based exercise programs in phase 1 (inpatient phase) and phase 2 (outpatient phase) of CR and exclusion criteria of studies using pedometer in maintenance phase CR. The primary outcome of the study is step count, while secondary is PA (in terms of time), heart rate, sedentary behaviour, and quality of life. This study quality was assessed by the Downs and Black’s checklist. Results: The study includes 6 RCTs based on the inclusion and exclusion criteria. Most studies show a considerable increase in step count associated with increased patient PA. Few studies have explained a significant increase of PA in the study group and maintained for longer terms. More research is needed to determine the impact of cardiovascular risk factors.
