Acute Blood Pressure Response to Different Types of Isometric Exercise: A Systematic Review with Meta-Analysis

Background: This study aimed to identify the blood pressure (BP) responses during different types of isometric exercises (IE) in adults and evaluate whether BP according IE is influenced by characteristics participants exercise protocols. Methods: The search was conducted PubMed, Cochrane Central, SPORTDiscus, LILACS databases June 2020. Random effects models with a 95% confidence interval p < 0.05 were used analyses. Results: Initially, 3201 articles found and, finally, 102 studies included this systematic review, seven which meta-analysis comparing handgrip other IE. Two-knee extension deadlift promoted greater increases systolic (+9.8 mmHg; = 0.017; I2 74.5% +26.8 ≤ 0.001; 0%, respectively) diastolic (+7.9 0.022; 68.6% +12.4 36.3%, compared handgrip. Men, middle-aged/elderly adults, hypertensive individuals, protocols higher intensities potentiate (p 0.001). Conclusions: involving larger muscle groups elicit than those smaller masses, especially men, individuals. Future should directly compare various populations.
