Tags : Spinal cord injuries Exercise Rehabilitation Technology Physical fitness Oxygen consumption Résumé : Background: Many wheelchair users adopt a sedentary lifestyle, which results in progressive physical deconditioning with increased risk of musculoskeletal, cardiovascular and endocrine/metabolic morbidity and mortality. Engaging in a walking program with an overground robotic exoskeleton may be an effective strategy for mitigating these potential negative health consequences and optimizing fitness in this population. However, additional research is warranted to inform the development of adapted physical activity programs incorporating this technology.
Objectives: To determine cardiorespiratory demands during sitting, standing and overground walking with a robotic exoskeleton and to verify whether such overground walking results in at least moderate-intensity physical exercise.
Methods: We enrolled 13 long-term wheelchair users with complete motor spinal cord injury in a walking program with an overground robotic exoskeleton. Cardiorespiratory measures and rate of perceived exertion (RPE) were recorded by using a portable gas analyzer system during sitting, standing and four 10m walking tasks with the robotic exoskeleton. Each participant also performed an arm crank ergometer test to determine maximal cardiorespiratory ability (i.e., peak heart rate and O2 uptake [HRpeak , VO2peak ]).
Results: Cardiorespiratory measures increased by a range of 9%35% from sitting to standing and further increased by 22%52% from standing to walking with the robotic exoskeleton. During walking, median oxygen cost (O2Walking ), relative HR (%HRpeak ), relative O2 consumption (%VO2peak ) and respiratory exchange ratio (RER) reached 0.29mL/kg/m, 82.9%, 41.8% and 0.9, respectively, whereas median RPE reached 3.2/10. O2Walking was moderately influenced by total number of sessions and steps taken with the robotic exoskeleton since the start of the walking program.
Conclusion: Overground walking with the robotic exoskeleton over a short distance allowed wheelchair users to achieve a moderate-intensity level of exercise. Hence, an overground locomotor training program with a robotic exoskeleton may have cardiorespiratory health benefits in the population studied.

Tags : Walking Menopause Physical fitness Obesity Lipoprotein levels Participants compliance Résumé : Objective : The aim of this study was to evaluate the impact of brisk walking on physical fitness, body composition and fasting lipid-lipoprotein profile of women 5065 years-old, once adherence or exercise intensity is considered.
Methods : A sample of 159 healthy, sedentary, obese postmenopausal women (body mass index [BMI]=2935kg/m2) was subjected to 3 sessions/week of 45 min-walking, at 60% of heart rate reserve (HRR), during 16 weeks. Body composition, physical fitness and fasting lipid-lipoprotein profile were assessed before and after the intervention.
Results : Among the three tertiles of adherence to exercise sessions (87%) women displaying the greatest one were characterized by the highest reduction in body weight (−1.9±2.7kg) (mean±SD), fat mass (−2.0±2.3kg) and waist girth (−4.4±3.4 cm) and the best improvement in physical fitness (7.3±3.5mL O2 /kg/min), (P 63% HRR) did not show between-group differences in body composition or physical fitness. Also, the fasting lipid-lipoprotein profile was improved by a reduction of cholesterol, LDL cholesterol, and triglyceride levels and by an increase in HDL cholesterol, irrespective of the participants adherence (0.05 Conclusions : A high practice rate seems to be the most important factor for physical fitness improvement and fat mass loss. Health benefits appear at 78 minutes of brisk walk per week and increase with adherence to training, in moderately obese and initially sedentary, postmenopausal women.
