Key result
HIIT increases EDV, LV mass, stroke volume, and EF in untrained men.
Why the study?
There are few data describing cardiovascular adaptations arising from high-intensity interval training (HIIT) interventions compared to traditional prolonged training.
Does high-intensity interval training improve cardiac morphology and function in untrained young men?
Comparison

HIIT may induce LV remodeling in untrained young men; leaves open durability, safety, and relevance to clinical populations.

Does high-intensity interval training improve cardiac morphology and function in untrained young men?
p-value: p=0.001
High-intensity interval training induces significant cardiac remodeling and functional improvements, including increased end-diastolic volume, left ventricular mass, and stroke volume in previously untrained young men.
Saadatnia et al. (2016) conducted an RCT in Untrained healthy individuals (n=22). High-intensity interval training (HIIT) vs. Control was evaluated on Cardiac morphology and function (including EDV, LVM, stroke volume, and EF) (p=0.001). High-intensity interval training significantly increased end-diastolic volume (P=0.001), left ventricular mass (P=0.002), stroke volume (P=0.003), and ejection fraction (P=0.001) in untrained men.
