Filter by:Background: Patients awaiting bariatric surgery, apart from suffering higher BMI, show a large number of comorbidities and a low physical fitness. These factors are associated with a longer surgery time, a longer hospital stay and a greater number of operative complications. To reduce these disadvantages, a nutritional intervention is performed to reduce total weight and the comorbidities associated with obesity prior to surgery. However, the prescription of an exercise program, which can be an effective tool to improve these factors, is not usually part of the usual care of these patients. Objective: To know the effects of a semi-supervised exercise program on body composition, cardiovascular risk factors and operative complications in bariatric patients. Methods: Approximately 3 months before surgery, 60 patients awaiting bariatric surgery will be recruited. Patients will be randomized into two groups: a) an experimental group (n = 30); b) a control group (n = 30). The experimental group will perform a semi-supervised exercise program, while the control group will only perform the corresponding evaluations. Both groups will be assessed for body composition, cardiovascular risk factors, physical condition, quality of life and physical activity levels at the beginning and at the end of the intervention. In addition, surgery time, hospital length of stay and operative complications will be evaluated in both groups.
The National Records of Scotland population projections show the pension age population increasing by 25% over the next 25 years. Falls are a major cause of hospitalisation in older adults, one in three community dwelling older adults over 65 years of age fall each year. There is a need to explore novel methods of delivering care to a growing older adult population. A programme of exercise called OTAGO has been found to reduce the number of falls for older adults. Several studies have explored the use of students to lead exercise interventions but these have not included assessing the impact to student educational experiences and outcomes with varying degrees of success on patient outcomes and no adverse events. Research Aim: To examine the feasibility of a student-led exercise intervention in improving falls risk outcomes for community dwelling older adults at risk of falling referred from NHS falls services. Study Design: A feasibility study examining a single patient group undertaking a 12 week, student-led, OTAGO exercise class for community dwelling older adults at Glasgow Caledonian University. OTAGO consists of progressive strength and balance exercises. Participants will be screened, invited to consent to the trial, asked to undertake the 12 week intervention and assessed using physical measures before and after the trial and face to face interviews after the trial. Recruitment will be through the NHS Greater Glasgow and Clyde and Lanarkshire community falls teams and the exercise delivery is consistent with usual care, the main difference is the location and student leaders. Students are qualified OTAGO Leaders. Funding has been received from AGILE the Chartered Society of Physiotherapists professional network working with older adults. Student educational experiences and outcomes will be assessed over the study period and are included in a separate study protocol
This study evaluates the influence of motor imagery and the observation of actions on pain perception. Participants in this study are asymptomatic subjects who will perform an IM and AO protocol of an aerobic exercise.
The phenotype based on the insertion/deletion (I/D) polymorphism of the human angiotensin converting enzyme (ACE) gene has been associated with individual training response. Briefly, intervention studies have demonstrated an 11-fold greater training-induced improvement in muscular endurance for ACE I/I homozygotes compared to ACE D/D homozygotes. Importantly, the ACE I/D polymorphism causes large inter-individual differences in serum ACE activity. Because the ACE D/D genotype is characterized by high plasma ACE activity and potentially blunted endurance exercise training response, it appears likely that ACE inhibitors (ACEi) have the potential to improve the outcome of exercise training for ACE D/D homozygotes. Thus, in the present study the investigators apply a randomized double-blind placebo-controlled longitudinal design to investigate whether pharmacological inhibition of ACE activity can amplify the exercise training response in healthy humans carrying either the ACE D/D or ACE I/I genotype. The study hypothesis is that inhibition of ACE activity in healthy humans with the ACE D/D genotype will amplify the health beneficial effects of exercise training while this is not the case in ACE I/I homozygotes.
Introduction: Studies on resistance training (RT) associated with blood flow restriction (BFR) have emerged as an alternative method of gaining strength and hypertrophy; however, the cardiovascular and autonomic repercussion of BFR at different intensities is unknown. Thus, it becomes relevant to investigate this type of training in post-exercise. Objective: investigate and compare autonomic and hemodynamic responses of acute eccentric RT with different intensities associated or not to BFR in healthy youngsters. Method: This is a randomized clinical trial including 60 healthy men aged 18-35 years, divided into four groups according to exercise intensity and BFR: 80% without BFR, 40% without BFR, 80% with BFR and 40% with BFR. Exercise intensity will be determined by the peak of excentric torque on the dinamometer isokinetic method and by the BFR, as being 40% of the intensity required for the complete examination of the blood flow evaluated by Doppler. Participants will do an eccentric femoral quadriceps muscle exercise session on the isokinetic dynamometer according to the previously randomized group. For recovery analyzes, the recovery heart rate (HRR) in the 1st (HRR1) and 2nd (HRR2) minute, rMSSD of 30 seconds, the hemodynamic parameters (heart rate, systolic and diastolic blood pressure, respiratory rate, peripheral oxygen saturation and rate pressure product) and heart rate variability (HRV) indices analyzed in the time domain (mean HR, rMSSD and SDNN), frequency domain (LF and HF [nu and ms2]) and Poincaré plot (SD1 and SD2). The analysis will be occur on baseline, immediately e after the excentric exercise and in the post exercise period for 60 minutes. Descriptive statistics method and comparison of HRV indices and hemodynamic parameters between moments and groups will be performed with the aid of the analysis of variance technique for the repetitive measures model without the schema of two sets of tests to follow . The level of significance will be p <0.05.
Clinical prescription and use of opioids is a clear problem in large parts of the world and has the recent years received an increasing publicity in sports. This is in particular due to the World Anti-Doping Agency monitoring list, which reveal that endurance athletes utilize the opioid Tramadol frequently with the aim to enhance performance according to anecdotal evidence. Studies investigating the effect of tramadol on exercise performance in healthy humans is limited to one study in moderate trained subjects. However, this effect may be different in highly trained subjects due to the effects of chronic exercise. Furthermore, ingestion of tramadol may impact motor-cognitive performance and it remains unknown whether tramadol can be detected in highly trained subjects following exercise. In the present study the investigators apply a randomized double-blind placebo-controlled counterbalanced cross-over design to investigate whether tramadol treatment improves a preloaded cycling time trial performance, whether it affects motor-cognitive performance and whether it is detectable following exercise.
This study evaluates the effects of a structured exercise (The LFN-exercise protocol) program plus diet, on cerebral hemodynamics (cerebral blood flow) and hepatic hemodynamics (portal pressure), as well as on nutritional status (body composition and nutritional markers) in order to facilitate the prescription of exercise in patients with cirrhosis.
- Physical exercise for 6 months produced significant improvement in adiponectin, hs-CRP, and nitric oxide (NO) and was significantly correlated with adiposity markers, lipid profile and glycemic control factors in both obese and non-obese diabetic patients. - Patients with good physical activity reported a significant decrease in BMI, CHD risk scores, reduced hs-CRP, an increase in the levels of adiponectin and nitric oxide. - In patients with type 2 diabetes mellitus, adiposity markers, lipid profile, hs-CRP, and adiponectin were significantly improved following moderate exercise interventions
This study evaluates possible barriers to physical activity/exercise training for patients with chronic kidney disease in Europe. The study's aim is to investigate structural problems and attitudes at different levels of care. Both a systemic and individual approach are applied. Barriers due to health care organisation and reimbursement policies will be investigated in the health care system and at the renal unit. Perceived benefits of physical activity and personal attitudes towards a healthy lifestyle will be investigated in nephrologists and renal nurses. Patients' health related quality of life, attitudes and perceived availability will be explored.
This study planned to investigate the effect of hip-focused neuromuscular activation exercise on foot posture and neuromuscular control in symptomatic and asymptomatic participants. We will follow a cross-over study design to compare the effect of hip focused neuromuscular activation exercise or a sham exercise on foot posture and lower extremity biomechanics. Foot posture will be assessed by Navicular Drop Test (NDT), and lower extremity neuromuscular control will be assessed with Star Excursion Y-Balance Test (SEBT-Y) and Frontal Plane Projection Angle (FPPA) during single leg squat before and after the experiments. The results of this study may provide scientific knowledge for a kinetic chain approach during functional foot rehabilitation.
