Key result
Four weeks of high-intensity intermittent training significantly increased HDL-C and decreased triglycerides, VLDL-C, BMI, and blood pressure compared to a non-exercising control group in obese middle-aged men.
Why the study?
Elevated blood lipids and physical inactivity are recognized risk factors for atherosclerosis.
Does 4 weeks of high-intensity intermittent training or continuous walking improve atherogenic indices, BMI, and blood pressure in obese middle-aged men compared to no exercise?
RCT (n=36)
Open-label

No
Does 4 weeks of high-intensity intermittent training or continuous walking improve atherogenic indices, BMI, and blood pressure in obese middle-aged men compared to no exercise?
Absolute Event Rate: 45.2% vs 38.9%
p-value: p=0.042
A 4-week high-intensity intermittent training program significantly improves lipid profiles, BMI, and blood pressure in obese middle-aged men compared to no exercise.
Supports 4-week HIIT for obese middle-aged men to improve lipids and BP; confirms efficacy of brief high-intensity exercise in RCTs.
Background and objectives: Elevated blood lipids and physical inactivity are known risk factors of atherosclerosis. The objective of this study was to compare effects of four weeks of high-intensity intermittent training (HIIT) and continuous walking on atherogenic indices of obese middle-aged men.

Shahamat et al. (2021) conducted an RCT in Obesity (n=36). High-intensity intermittent training (HIIT) vs. No-exercise control was evaluated on High-density lipoprotein cholesterol (HDL-C) (p=0.042). Four weeks of high-intensity intermittent training significantly increased HDL-C and decreased triglycerides, VLDL-C, BMI, and blood pressure compared to a non-exercising control group in obese middle-aged men.
