Key result
MIIT improves VO2max over HIIT and usual care in patients with acute myocardial infarction.
Why the study?
Increasing VO2max is important for acute myocardial infarction morbidity and recurrence, with exercise intensity suggested as a key factor in improving VO2max.
Does maximal-intensity interval training improve exercise capacity and quality of life compared to high-intensity interval training and usual care in patients with acute myocardial infarction?

Does maximal-intensity interval training improve exercise capacity and quality of life compared to high-intensity interval training and usual care in patients with acute myocardial infarction?
p-value: p=<0.001
Maximal-intensity interval training significantly increases V̇O2max more than high-intensity interval training and usual care in post-MI patients, suggesting higher intensity in phase II cardiac rehabilitation yields better physiological outcomes.
No takes yet. Share an insight, caveat, or question.
MIIT may outperform HIIT for VO2max gains in low-moderate risk post-MI patients; extends RCT comparisons of interval training intensity in cardiac rehab.
Nam et al. (2023) conducted an RCT in acute myocardial infarction (n=91). Maximal-intensity interval training (MIIT) vs. High-intensity interval training (HIIT) and usual care was evaluated on maximum oxygen intake (V̇O2max) (p=<0.001). Maximal-intensity interval training significantly increased VO2max compared to high-intensity interval training and usual care in patients with acute myocardial infarction (P<0.001).
