Brief Summary

Peripheral arterial disease is part of the diseases derived from arteriosclerosis are the leading cause of mortality in developed countries. There is evidence of the benefits of physical exercise programs supervised in patients with cardiovascular risk. Despite being a treatment with proven efficacy and relatively inexpensive, it continues being little used for the management of patients with intermittent claudication caused by peripheral arterial disease. The objective of this study is to develop an evidence-based intervention strategy on the effectiveness of supervised physical exercise in intermittent claudication to determine its impact compared to standard counselling in these patients.

Study Arms (4)

Walking intervention group

EXPERIMENTAL

It will consist of performing the Treadmill training progression for 36-72 sessions. 3 sessions of 60 minutes, will be held weekly.

Other: Walking intervention

Strength intervention group

EXPERIMENTAL

The training program consists of performing a training program with resistance exercises for 36-72 weeks.

Other: Strength intervention

Concurrent intervention group

EXPERIMENTAL

The training program consists of alternating strength and resistance stimuli in the same session for 36-72 weeks. There will be 3 weekly sessions of 60 minutes, where exercises with resistance will be applied for 35 minutes and to complete the 60 minutes, the same guidelines will be followed as in the walking exercise, applying resistance stimuli.

Other: Concurrent intervention

Control group

NO INTERVENTION

It will receive standard advice consisting of the recommendation to perform aerobic exercise at the lower limbs level.

Interventions

It will consist of performing the Treadmill training progression for 36-72 sessions. 3 sessions of 60 minutes, will be held weekly. Depending on the data obtained in Visit 1, the speed will be determined for each patient and the degree of the initial slope that is comfortable when walking until it induces symptoms of moderate intermittent claudication. The progression of the intensity of the speed and incline of the slope will be increased progressively and individually for each patient.

Walking intervention group

The training program consists of performing a training program with resistance exercises for 36-72 weeks. There will be 3 weekly sessions of 60 minutes, where exercises with resistance will be applied. The same guidelines will be followed as in the walking exercise, but in this case, applying force stimuli. If symptoms of moderate intermittent claudication occur (3-4) based on the Claudication Symptom Rating Scale in 5-10 minutes, a period of rest (sitting or standing) will be performed until the pain disappears at the level of the lower limb. This sequence will be repeated until the strength training session is completed. The progression of force stimuli will be increased weekly depending on the subjective perception of the patient's effort and according to the guidelines set by our group of investigation.

Strength intervention group

The training program consists of alternating strength and resistance stimuli in the same session for 36-72 weeks. There will be 3 weekly sessions of 60 minutes, where exercises with resistance will be applied for 35 minutes and to complete the 60 minutes, the same guidelines will be followed as in the walking exercise, applying resistance stimuli. If claudication symptoms occur moderate intermittent (3-4) based on the Claudication Symptom Rating Scale in 5-10 minutes, a period of rest (sitting or standing) will be performed until the pain in the lower extremity disappears. This sequence will be repeated until the 20 minutes established to end the session are completed concurrent training. The progression of the strength and resistance stimuli will be increased weekly depending on the perception subjective effort of the patient and according to the guidelines established by our research group.

Model Details: Randomized longitudinal controlled trial, parallel, blinded to the analysis, with a sample of participants studied between 3 and 6 months after starting a physical exercise program. Participants will be randomly assigned to four groups. Intervention walking group: The intervention will consist of carrying out the walking training progression. The strength group will carry out a resistance training program. The concurrent training intervention group will carry out an exercise program that will alternate strength and endurance training in the same session. Both experimental groups will hold 36-72 sessions, with a frequency of 3 sessions per week and 60 minutes per session. The control group will receive standard advice consisting of the recommendation to perform aerobic exercise at the lower limbs level warning.
