Effects of interval training on haemodynamic variables after coronary artery bypass graft: A meta-analysis.

Objective: To assess the combined impact of interval training programme on haemodynamic variables, specifically blood pressure and heart rate, in patients having undergone coronary artery bypass graft surgery. METHODS: The meta-analysis was conducted from October to December 2022, and comprised search on PubMed, MEDLINE, Web of Science, PeDro, EMBASE, Science Direct, Cochrane Central Register of Controlled Clinical Trials, Google Scholar and Scopus electronic databases by two researchers independently for literature published between 2009 and 2020 related to the effects of interval training on coronary artery bypass graft patients. Meta-analysis was then performed to analyse the effects of an interval training on systolic blood pressure, diastolic blood pressure, and heart rate. The meta-analysis was performed in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. RESULTS: Of the 122 studies initially located, 7 were related to the effects of different forms of interval trainings and their impact on systolic and diastolic blood pressure of the patients, and 5 studies analysing the effects of interval trainings on heart rate. Interval training showed mild improvement in decreasing SBP compared to control groups. Standardized mean difference suggested an effect size of -0.226 in random effect model (I2=52.01; p=0.064). Similarly, a small effect size of 0.136 (I2=39.19%, p=0.14) was observed for diastolic blood pressure. Also, there was a small effect size of 0.155 (I2= 28.08, p=0.23) observed for heart rate. Conclusion: Interval training programmes, including high-intensity interval training, low-volume interval training, and aerobic interval training, had a small effect on systolic blood pressure, whereas continuous training protocols had a similarly small effect size on diastolic blood pressure and heart rate.

Improving Kyphotic Postures and Neck Pain in Young Adults: A Meta-Analysis of Exercise-Based Interventions.

The study aimed to review the findings concerning the effects of exercises on Cobb angle and pain in patients suffering from cervical pain caused by thoracic kyphosis. Two investigators separately conducted a systematic review of the electronic literature from 2018 till 2022. PubMed, MEDLINE, Web of Science, Science Direct, Cochrane Central Register of Controlled Clinical Trials, Google Scholar, and Scopus were among the electronic databases that were accessed. This meta-analysis included 5 studies, published between 2019 and 2022. A sample size of 261 patients; included in 5 studies were estimated on Cobb angle and pain. The between-groups pooled random SMD for Cobb angle and pain showed a larger effect size of -2.146 and -1.126, respectively. The findings suggested that physical therapy exercise may result in larger changes among the Cobb angle and neck pain of kyphotic patients.
