Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Low volume high intensity interval training
This group will receive the usual care (standard medical treatment) in addition to LV-HIIT on a treadmill for 8 weeks, 2 sessions per week.
low-volume high intensity interval training
Low-volume HIIT (LV-HIIT) is a particularly time-efficient subtype of interval training, which has gained increasing attention in recent years. As per the previous definition, these brief training protocols typically involve≤10 min of intense exercise within a session lasting≤30 min including warm-up, recovery phases between intervals, and cool-down
Standard medical treatment
standard medical treatment for chronic heart failure as per international guidlines
high volume high intensity interval training
In this group, the patients will receive the usual care (standard treatment) in addition to HV-HIIT on a treadmill for 8 weeks, 2 sessions per week
High volume high intensity interval training
long (2-4 min) bouts of high (not maximum) intensity exercise interspersed with recovery periods which have wide varieties in the protocols according to the intensity, duration, and number of intervals performed
Standard medical treatment
standard medical treatment for chronic heart failure as per international guidlines
control group
It includes 15 patients who will receive standard medical treatment only
Standard medical treatment
standard medical treatment for chronic heart failure as per international guidlines
