Why the study?

Does a high intensity exercise training programme improve quality of life and physical working capacity compared to light exercise in men after acute myocardial infarction?

Population

224 men under 70 years of age admitted to a coronary care unit with transmural acute myocardial infarction

Comparison

Group programme lasting eight weeks of high… vs Group programme lasting eight weeks of light…

Design

RCT, Randomly allocated in hospital

Follow-up

1 year

Implication

Light exercise yields equivalent long-term post-MI outcomes to high-intensity training; extends evidence that short-term intensity gains are not sustained.

Key Points

To determine if light exercise improves quality of life after acute myocardial infarction as effectively as high intensity training.
Random allocation of 224 men to high intensity or light exercise programmes for eight weeks.
Assessment of physical working capacity and quality of life via treadmill tests and self-report scores at multiple time points.
Analyzed data after 11 weeks and one year using repeated measures analysis.
At 11 weeks, mean metabolic equivalents were 10.7 for high intensity and 9.7 for light exercise (p = 0.005).
No significant differences in quality of life or treatment effects observed at one year.
Improvement in occupational adjustment score was greater in high intensity group at four months than in light exercise group.

Structured PICO

Does a high intensity exercise training programme improve quality of life and physical working capacity compared to light exercise in men after acute myocardial infarction?

Population

224 men under 70 years of age admitted to a coronary care unit with transmural acute myocardial infarction

Intervention

Group programme lasting eight weeks of high intensity exercise training

Comparator

Group programme lasting eight weeks of light exercise

Outcome

Physical working capacity based on metabolic equivalents achieved from treadmill exercise tests and quality of life based on self report scores and interview assessments at entry, after 11 weeks/4 months, and after one yearpatient reported

A low-cost program of light exercise yields similar long-term quality of life benefits as a high-intensity exercise training program in men recovering from acute myocardial infarction.
