Filter by: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 will compare short-term post-exercise muscle glycogen synthesis following combined galactose-glucose, glucose alone or galactose alone ingestion.
The aim of the study was to evaluate the effect of a 8 week training period compared with control group in physical and mentally disabled adults. The effect was evaluated in relation to their physical status. Furthermore, physical activity was measured using steps and active minutes.
This study is designed as a single blind randomized controlled trial. Thirty-six elderly with non-specific low back pain (NSLBP) will be recruited. The participants will randomly divided two parallel groups as control and intervention. Traditional physiotherapy methods will be applied to all participants. Traditional physiotherapy will include heat modality (a hot pack for 15 minutes), electrotherapy (transcutaneous electrical nerve stimulation (TENS), a 50 Hz conventional TENS with a pulse duration <150 microseconds). For the control group, core stability exercise will be applied 3 days/week, 6 weeks. For the intervention group, in addition to the core stabilization exercises myofascial relaxation technique will be performed with roller massager ((Thera-Band; The Hygenic Corporation, Akron, OH) 3 days/week, 6 weeks. The myofascial relaxation technique will be performed along the superficial back line. To the best of our knowledge, there is no randomized controlled study investigating the effect of the myofascial release technique combined with core stabilization in elderly with NSLBP. This study aimed to investigate the myofascial release technique combined with core stabilization exercise in elderly with NSLBP.
TITLE: Effects of a high-intensity progressive-cycle program on quality of life and motor symptomatology in Parkinson's disease population BACKGROUND: The benefits of aerobic exercise in persons with Parkinson's disease (PD) have been widely studied; however, little research has been done on the effect of high-intensity aerobic exercise in this group. HYPOTHESIS: The high-intensity aerobic training in pedaliers, combined with balance training, improves motor symptoms and quality of life in a population with Parkinson Disease, Hoehn & Yahr 1-3. OBJETIVES: To ascertain whether high-intensity aerobic training with exercise peddlers and balance training can improve motor symptoms and quality of life in a PD population of Hoehn &Yahr (H&Y) disability score 1-3. METHODOLOGY Setting: Rehabilitation centers in secondary care. Design: A pilot randomized controlled trial. Participants: A total of 14 patients participated in the 8-week study. Interventions: They were comprised of a control group (n=7) that followed a balance protocol and an experimental group (n=7) that performed high intensity (70%) aerobic workout using an exercise peddler + a balance protocol once a week. Main Outcome Measures: The primary outcome measures included the 8-Foot Up and Go, test, 6-minute walk test, test 2-minute step tets, Parkinson Disease Questionnaire-39 (PDQ39), Unified Parkinson's Disease Rating Scale (MDS-UPDRS) and Tinetti test.
Whole Body Vibration Therapy (WBVT) has been identified as a useful tool to increase peripheral blood flow. The present study aimed at how dynamic exercises with WBVT immediate effect on hemodynamic response and fatigue parameters in patients with obesity.
