Exercise Training in Individuals With Peripheral Arterial Disease

September 19, 2017 updated by: Borut Jug, University Medical Centre Ljubljana

Influence of Different Types of Exercise Training on Selected Cardiovascular Parameters in Individuals With Peripheral Arterial Disease

In this controlled trial, patients with peripheral arterial disease will be randomized to either maximal walking, submaximal walking, or usual care groups.

Detailed Description

Exercise training (walking) is a recommended therapeutic intervention for patients with peripheral arterial disease (PAD). Studies have shown that exercise training improves walking distance, pain-free walking distance, endothelial function and quality of life in these patients. However, to date the most effective exercise training option in terms of improvement of cardiovascular parameters has not been clearly identified. In this controlled trial, patients with PAD will be randomized to either maximal walking group, submaximal walking group, or usual care. The aim of the study is to compare the effect of maximal vs. submaximal walking training programmes on i) walking ability, ii) vascular function, iii) arrhythmogenic potential, iv) parameters of inflammation, hemostasis and heart failure severity, v) health-related quality of life in individuals with PAD.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
ACTIVE_COMPARATOR: Maximal walking group
Patients to be randomized to the 'maximal walking group' will have exercise training sessions 3 times per week for a period of 12 weeks. They will undergo an exercise training programme consisting of 60 minutes of repetitive interval muscle training/walking up to the point of pain-free walking distance.
Other: Exercise training
Patients to be randomized to the 'maximal walking group' or 'submaximal group' will undergo exercise training sessions 3 times per week for a period of 12 weeks.
ACTIVE_COMPARATOR: Submaximal walking group
Patients to be randomized to the 'submaximal walking group' will have exercise training sessions 3 times per week for a period of 12 weeks. They will undergo an exercise training programme consisting of 60 minutes of repetitive interval muscle training/walking up to 2/3 of pain-free walking distance.
Other: Exercise training
Patients to be randomized to the 'maximal walking group' or 'submaximal group' will undergo exercise training sessions 3 times per week for a period of 12 weeks.
NO_INTERVENTION: Usual care group
Patients to be randomized to the 'usual care group' will undergo standard care for 12 weeks.
