Walking Training Improves Ambulatory Blood Pressure Variability in Claudication.

Background: Walking training (WT) improves walking capacity and reduces clinic blood pressure (BP) in patients with peripheral artery disease (PAD), but its effects on ambulatory BP remains unknown.

Objective: To investigate the effect of 12 weeks of WT on ambulatory BP and its variability in patients with PAD.

Methods: Thirty-five male patients with PAD and claudication symptoms were randomly allocated into two groups: control (n = 16, 30 min of stretching) and WT (n = 19, 15 bouts of 2 min of walking at the heart rate of leg pain threshold interspersed by 2 min of upright rest).

Reproducibility of Anaerobic and Pain Thresholds in Male Patients With Intermittent Claudication.

Purpose: Maximal and submaximal parameters assessed during treadmill tests are used to prescribe exercise training and assess exercise-induced adaptations in patients with intermittent claudication (IC). Although reproducibility of maximal parameters is well documented, the reproducibility of submaximal is not clear. The aim of this study was to identify the reproducibility (reliability and agreement) of heart rate (HR) and oxygen uptake ((Equation is included in full-text article.

Are the barriers for physical activity practice equal for all peripheral artery disease patients?

Objective: To investigate barriers to physical activity related to the sociodemographic comorbidities and clinical variables of patients with intermittent claudication.

Design: Cross-sectional study.

Setting: Ambulatory care.

Post-walking exercise hypotension in patients with intermittent claudication.

Purpose: This study aimed to investigate the acute effect of intermittent walking exercise (WE) on blood pressure (BP) responses in patients with intermittent claudication (IC). Secondly, this study aimed to gain improved insight into the physiological mechanisms controlling BP regulation after intermittent WE in this patient group.

Methods: Twenty patients with IC participated in two experimental sessions in a random order, as follows: WE (15 × 2-min bouts of WE interpolated with 2-min rest intervals) and control (standing rest on a treadmill for 60 min).

Comparison between subjective and objective methods to assess functional capacity during clinical treatment in patients with intermittent claudication.

Objective: To analyze if there is any relation between functional capacity assessed by subjective and objective methods regarding the current state and after clinical treatment in patients with intermittent claudication.

Methods: A total of 500 patients with intermittent claudication were enrolled. All patients underwent clinical examination and a functional evaluation by subjective (clinical visit) and objective method (treadmill test).

Effects of clustered comorbid conditions on walking capacity in patients with peripheral artery disease.

Background: Comorbid conditions are known to increase cardiovascular risk in patients with peripheral artery disease (PAD). However, whether comorbid conditions affect walking capacity remains controversial. Previous studies have analyzed comorbidities separately, but they are known to occur in a clustered fashion in PAD patients.

Exercise prescription using the heart of claudication pain onset in patients with intermittent claudication.

Objective: To assess the acute metabolic and cardiovascular responses to walking exercise at an intensity corresponding to the heart rate of claudication pain onset and to investigate the effects of a 12-week walking training program at this intensity on walking capacity.

Methods: Twenty-nine patients with intermittent claudication were randomly allocated to the walking training (n=17) or control (CO, n=12) group. The walking training group performed an acute exercise session comprising 15×2-min bouts of walking at the heart rate of claudication pain onset, with 2-min interpolated rest intervals.

Predictors of walking capacity in peripheral arterial disease patients.

Objective: To estimate walking capacity in intermittent claudication patients through a prediction model based on clinical characteristics and the walking impairment questionnaire.

Methods: The sample included 133 intermittent claudication patients of both genders aged between 30 and 80 years. Data regarding clinical characteristics, the walking impairment questionnaire and treadmill walking test performance were obtained.

Stages of health behavior change and factors associated with physical activity in patients with intermittent claudication.

Objective: To analyze, in people with intermittent claudication, the frequency of individuals who are in each of stages of health behavior change to practice physical activity, and analyze the association of these stages with the walking capacity.

Methods: We recruited 150 patients with intermittent claudication treated at a tertiary center, being included those > 30-year-old-individuals and who had ankle-arm index < 0.90.
