NCT02009475

Brief Summary

The aim of the present study is to evaluate differential lactate removal kinetics in heart failure patients that are trained according to 2 different exercise protocols: (A) High intensity intervals training (HIT); (B) Continuous moderate aerobic training (MAT)

Outcome Measures

Primary Outcomes (1)

  • Lactate clearance kinetics

    Change from baseline of lactate clearance kinetics followoing a 12 weeks exercise program based on two different training protocol (continues and interval training)

    Baseline and following 12 weeks of training

Secondary Outcomes (1)

  • Peak VO2 change

    Pre- and post 12 week exercise program

Other Outcomes (1)

  • Quality of life questioner (MLWHF)

    Pre training and 12 weeks later post exercise training period

Study Arms (2)

Continues aerobic training

ACTIVE COMPARATOR

Treadmill or exercise bike training with target heart rate of 50-70% of the heart rate reserve (or 50-60% of the peak VO2 reserve). Overall 45 minutes of exercise (including the 5-10 minute warm-up period).

Other: Continues aerobic training

Interval Exercse Training

EXPERIMENTAL

Bouts of high intensity interval treadmill or exercise bike training, comprising of 85-95% of the heart rate reserve (or 80-90% of the peak VO2 reserve), for the duration of 4 minutes, separated by periods of low intensity activity until the heart rate reaches 50% of the peak heart rate. This set will be repeated 3 times.

Other: Interval exercise training

Interventions

Interval Exercse Training
Continues aerobic training
