We performed a meta-analysis of randomized controlled trials (RCTs) assessing the effect of Aquatic High Intensity Interval Training (AHIIT) on cardiometabolic and physical health markers in women.
Systematic search used 7 databases (MEDLINE, PubMed, SPORTDiscus, Cochrane, Embase, CINAL complete, PsycINFO). The Physiotherapy Evidence Database (PEDro) score was used to evaluate the methodological quality of the studies. Clinical trials compared AHIIT with a control group that receive no exercise training. We integrated randomized controlled trials published in English, and participants were women aged 18 years. The outcome of interest was the change in cardiometabolic and physical health markers.
Among 242 articles screened, 18 articles (13 trials) were included in this meta-analysis comparing AHIIT (n ¼ 261) with a control group (n ¼ 215). The median PEDro score was 5.5 out of 10 (range, 4e8). AHIIT significantly improved peak oxygen uptake (Hedges’ g 0.610; 95% CI 0.277e0.943; P < 0.001), reduced resting heart rate (Hedges’ g 0.495; 95% CI -0.866 to 0.124; P < 0.05), as well as chair to stand test. (Hedges’ g 0.548; 95% CI 0.019 to 1.077; P < 0.05).
AHIIT has a moderate effect in improving cardiometabolic and physical health markers in women.
