Kwok (2022) The effect of aquatic High Intensity Interval Training on cardiometabolic and physical health markers in women: A systematic review and meta-analysis

Summary of the Effects of Aquatic High-Intensity Interval Training on Women’s Health


Aquatic High-Intensity Interval Training (AHIIT) is a novel approach in exercise, particularly for women. This systematic review and meta-analysis by Kwok et al. focuses on AHIIT’s impact on cardiometabolic and physical health markers in women.


The study analyzed randomized controlled trials (RCTs) involving women aged 18 years and above. The main parameters assessed were cardiometabolic health markers such as peak oxygen uptake (VO2 peak), resting heart rate (HR), and physical health markers including body fat percentage, bone mineral density, and muscular strength.


  • VO2 Peak and Resting Heart Rate: AHIIT showed a moderate improvement in VO2 peak and a reduction in resting HR. These parameters are crucial indicators of cardiometabolic health.
  • Blood Pressure and Lipid Profile: There was no significant reduction observed in systolic and diastolic blood pressure (SBP and DBP) or changes in lipid profile.
  • Body Fat Percentage: The effect of AHIIT on body fat percentage in women was not significant.
  • Muscle Strength and Bone Mineral Density: No significant changes were observed in knee extension and flexion strength or total body and femur bone mineral density.
  • Functional Improvement: There was a notable improvement in functional ability, as shown by the chair to stand test results.


AHIIT appears to be a beneficial exercise modality for improving certain cardiometabolic and physical health markers in women. However, its impact on blood pressure, lipid profile, body fat percentage, and muscle strength needs further investigation.
