NCT04829955

Brief Summary

Patients with ischemic cardiomyopathy and mildly reduced ejection fraction suffer from reduced functional capacity and fatigue caused by loss of muscle strength and reduced aerobic capacity. A few studies have shown that structured endurance and resistance training programs were able to improve walking capacity and limb strength. Although both concentric and eccentric training programs are beneficial for these patients, eccentric training is less stressful to the cardiovascular system. The aim of the study is to determine if eccentric-orientated body weight and manual resistance training in ischemic cardiomyopathy patients will lead to superior results compared to concentric training.

Study Arms (3)

Observation phase

NO INTERVENTION

After screening and randomization for either the eccentric orientated intervention group or the concentric orientated intervention group, all measurements will be made for the first time by investigators at point A1. An observational phase for six weeks will follow to achieve an intern acceptance sampling for the measurements which will be used.

Eccentric training group

ACTIVE COMPARATOR

Subjects in the eccentric training group (GEC) will attend six weeks of eccentric orientated training. The eccentric orientated training will use the cadence 3-0-1 for eccentric - break - concentric. * 3 sessions/week * 60 minutes per session including a warming up and cool down phase * 6 exercises * total of 18 sessions

Other: Eccentric manual resistance training

Concentric training group

ACTIVE COMPARATOR

The concentric training group (GCO) will attend six weeks of concentric orientated training. Each group will perform a manual resistance/bodyweight resistance training accentuating the concentric phase of the movement. The concentric orientated training will use the cadence 1-0-3 for eccentric - break - concentric. * 3 sessions/week * 60 minutes per session including a warming up and cool down phase * 6 exercises * total of 18 sessions

Other: Concentric manual resistance resistance training
