Acute Effects of Exercise in Peripheral Arterial Disease Patients
Sponsor: European University Miguel de Cervantes
Summary
Peripheral arterial disease (PAD) affects over 200 million people worldwide and is caused by narrowing of the arteries. Intermittent claudication, characterized by pain when walking, is its main symptom. Despite the proven benefits of exercise, there is no optimal protocol for treatment. To analyze the effects of different exercise conditions on proteomic and physiological markers in patients with PAD and to determine their preferences regarding exercise conditions. A clinical cross-over study with four randomized experimental conditions (aerobic training, traditional strength training, circuit training and control) will be conducted. Patients with grade IIa-IIb PAD according to the Leriche-Le Fontaine scale will be recruited from the Department of Angiology and Vascular Surgery Department of the Hospital Clínico Universitario de Valladolid. In each experimental session, measurements of cardiorespiratory capacity, post-exercise oxygen debt, ankle-brachial index, blood flow, peripheral oxygen saturation, perceived exertion, heart rate variability and blood proteome changes will be performed.

Interventions
Aerobic exercise
Intermittent walking will be performed on a treadmill (F2W DUAL, BHFitness®, Spain). There will be 8 sets of 2 minutes in duration at an intensity equivalent to the level at which the patient experienced claudication symptoms. The recovery period between each set will be two minutes. All training sessions will conclude with a cool-down period of 5 minutes of walking at 50-60% of peak heart rate, followed by 3 minutes of joint mobility exercises. Throughout the session, heart rate will be continuously monitored using a heart rate monitor (Polar H10, Polar Electro Ltd., Kempele, Finland) and the Polar Team application (Polar Electro Ltd., Kempele, Finland).
Traditional strength exercise
Two sets will be performed with a moderate-to-high effort level (15-16 repetitions out of 20RM) consisting of 6 multi-joint exercises. The recovery period after each set will be two minutes of passive rest. Each participant will be asked to move the load as quickly as possible during each repetition. All training sessions will conclude with a cool-down period of 5 minutes of walking at 50-60% of peak heart rate, followed by 3 minutes of joint mobility exercises. Throughout the session, heart rate will be continuously monitored using a heart rate monitor (Polar H10, Polar Electro Ltd., Kempele, Finland) and the Polar Team application (Polar Electro Ltd., Kempele, Finland).
Circuit strength exercise
Two sets (rounds) will be performed with a moderate-to-high effort level (15-16 repetitions out of 20RM) in a circuit consisting of 6 multi-joint exercises. The recovery time between exercises will be the minimum required to change exercises, and the recovery between sets (rounds) will be two minutes of passive rest. Each participant will be asked to move the load as quickly as possible during each repetition. All training sessions will conclude with a cool-down period of 5 minutes of walking at 50-60% of peak heart rate, followed by 3 minutes of joint mobility exercises. Throughout the session, heart rate will be continuously monitored using a heart rate monitor (Polar H10, Polar Electro Ltd., Kempele, Finland) and the Polar Team application (Polar Electro Ltd., Kempele, Finland).
