NCT01676870

Brief Summary

The primary objective of the study is to compare in a real-world setting the efficacy of traditional training (today's guideline, vigorously or moderate exercise) and amount of aerobic interval training (1-AIT) in reduction of risk factors constituting metabolic syndrome. The secondary objective is to compare the efficacy of traditional moderate training (today's guideline) and amount of aerobic interval training (1-AIT vs. 4-AIT) in improving aerobic capacity, cardiovascular function, skeletal muscle contractile function, skeletal muscle energy metabolism, left ventricle systolic and diastolic function at rest and right ventricular function. The investigators hypothesized that aerobic interval training would reverse features of the metabolic syndrome more than traditional training.

Interventions

endurance training as walking/running "uphill" 3 times/week for 16 weeks (2 supervised sessions (treadmill) and 1 at home each week) at 90% of Hfmax. Warm-up 10 min at 70% of maximal heart frequency (Hfmax), 5min cool-down.

1x4 aerobic interval training

endurance training as walking/running "uphill" 3 times/week for 16 weeks (2 supervised sessions (treadmill) and 1 at home each week) at 90% of Hfmax. Warm-up 10 min at 70% of maximal heart frequency (Hfmax), 3 min active pause between each interval, 5min cool-down.
