“…Twelve hours of walking exercise at the heart rate of claudication pain onset spread over 12 weeks induced improvements (in the claudication onset distance and total walking distance) that were similar in magnitude to the improvements previously observed after higher volume walking exercise training programs in patients with intermittent claudication (16–18). Claudication onset distance and total walking distance were increased by 104±141 m and 316±141 m, respectively, which represent clinically meaningful changes, particularly because our patient cohort had a higher walking capacity at baseline than that reported in previous studies (3,5,7).…”

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. The claudication symptoms and cardiovascular and metabolic responses were evaluated. Walking training was then performed at the same intensity twice each week for 12 weeks, while the control group engaged in twice weekly stretching classes. The claudication onset distance and total walking distance were evaluated before and after the interventions. Brazilian Registry Clinical Trials: RBR-7M3D8W.RESULTS:During the acute exercise session, the heart rate was maintained within tight limits. The exercise intensity was above the anaerobic threshold and >80% of the heart rate peak and VO2peak. After the exercise training period, the walking exercise group (n = 13) showed increased claudication onset distance (309±153 vs. 413±201m) and total walking distance (784±182 vs. 1,100±236m) compared to the control group (n = 12) (p<0.05).CONCLUSION:Walking exercise prescribed at the heart rate of claudication pain onset enables patients with intermittent claudication to exercise with tolerable levels of pain and improves walking performance.

“…home-based walking). However, relatively few studies have compared the efficacy of a homebased, unsupervised exercise program to a control group in patients with claudication, 77,78 none have used a randomized, controlled trial design, and most of the non-randomized trials have suffered from small sample sizes, [78][79][80][81][82][83][84] have had high percentages of dropouts, [84][85][86][87] and have focused primarily on ambulatory outcomes such as claudication distances without considering the impact of home-based exercise on vascular function. [88][89][90][91] In addition to these problems, the inability to accurately quantify the volume of exercise performed in home-based programs is the most serious limitation, rendering previously reported data as difficult to interpret.…”

Background: Peripheral artery disease (PAD) is characterized by arterial lesions of the lower extremities. Patients with PAD present ambulatory dysfunction due to intermittent claudication, limiting daily physical activity and increasing morbidity. Therefore, objectively measured daily ambulation is a clinically relevant outcome in these patients. Objective: To quantify daily ambulation with a step activity monitor (Step Watch 3 TM ; Cyma Inc., Mountlake Terrace, WA, USA) in patients with PAD. Major findings: Patients with claudication ambulate less each day than controls, as they take 1081 fewer strides (1 stride52 steps) and spend 48 fewer minutes ambulating each day. The cadence obtained during endurance ambulation (maximum cadences for 60, 30, and 20 continuous minutes of ambulation) and short bouts of ambulation (maximum cadence for continuous minutes of ambulation and for the minute having the single highest cadence value each day) is also lower in patients. Demographic factors and comorbid conditions, particularly sex, dyslipidemia, abdominal obesity, and the number of components of metabolic syndrome, affect the ambulatory activity patterns of patients with claudication. Conclusions: Patients with claudication perform a lower amount of daily ambulatory activities and lower intense physical activities than controls, which is impaired further by comorbid conditions. The clinical implication is that patients with claudication should not only be advised to walk more during each day, but to do so at a cadence that is higher than their self-selected slower cadence. This approach will increase total daily exercise volume by increasing both the duration as well as the intensity of ambulation.

“…Other mechanisms responsible for improvement in patients' functioning in response to exercise include, among others, improvement in the rheological properties of blood, reduction of risk factors of atherosclerosis, and improvement in walking economy. To date, the impact of exercise on the development of collateral circulation in patients with chronic lower limb ischaemia has not been fully confirmed [13–16]. …”

Objective. The objective of this paper is to compare the impact of supervised walking and resistance training upon the walking distance in PAD patients. Materials and Methods. The examination involved 50 PAD patients at the 2nd stage of the disease according to Fontaine's scale. The participants were randomly allocated to two groups: one exercising on the treadmill (n = 24) and one performing resistance exercises of lower limbs (n = 26). Results. The 12-week program of supervised rehabilitation led to a significant increase in the intermittent claudication distance measured both on the treadmill and during the 6-minute walking test. The group training on the treadmill showed a statistically significant increase of the initial claudication distance (ICD) and the absolute claudication distance (ACD) measured on the treadmill, as well as of ICD and the total walking distance (TWD) measured during the 6-minute walking test. Within the group performing resistance exercises, a statistically significant improvement was observed in the case of parameters measured on the treadmill: ICD and ACD. Conclusions. The supervised rehabilitation program, in the form of both walking and resistance exercises, contributes to the increase in the intermittent claudication distance. The results obtained in both groups were similar.
