Filter by:It is known that the global socioeconomic burden of individuals with knee osteoarthritis (OA) is on a constantly rising curve. In addition, it is predicted that this burden will increase with the increase in the aging rate of countries. While the evidence level of exercise in the treatment of individuals with knee OA is at A level, a standard exercise program has still not been established for these individuals. One of the most important elements in establishing a standard exercise protocol can be realized by understanding how exercise provides positive effects in these individuals. Today, the gold standard practice used in examining the effectiveness of treatments such as exercise is the follow-up of biomarkers. However, for this purpose, biological fluids (blood, urine, synovial fluid) samples are not taken from individuals with knee OA during routine health controls. Existing laboratory detection methods, especially ELISA analysis, are very detailed, time-consuming and expensive, among the reasons why they cannot be included in routine clinical practice. This situation makes it difficult to examine which biomarkers the exercise programs applied in individuals with knee OA have an effect on and to establish a standard exercise protocol. Therefore, the number of randomized controlled studies examining this issue is very few in the literature, and this number is much less in Turkey. The researchers aimed to create a standard home-based exercise program by examining the effects of the holistic exercise approach for all lower extremity muscles, which the researchers created considering the EMG studies in the literature for individuals with knee OA and the age group to be included in the study, both at the physical (pain, functional status, quality of life) and biochemical level (inflammatory biomarkers that have not been examined together before and whose relationship with OA has been newly discovered).
Using a Virtual Reality (VR) games-based application is as an innovative falls prevention technology in an aged care service. The VR intervention has promising effects on improving the physical and balance performances in the older adults.The study explored and evaluated the effects of VR activity-based training on falls prevention among community-dwelling older adults with mild cognitive impairment.
Background: The Fontan operation has been used to treat complex cardiac anomalies with a single-functioning ventricle. A study performed by Instituto do Coracão-Hospital das Clínicas-Universidade de Sao Paulo (InCor/HCFMUSP)-Brazil, Hospital das Clínicas of Ribeirão Preto-Brazil, department of the University of Aarhus, and Rigshospitalet, Denmark demonstrated an impairment peripheral lymphatic function in Fontan patients compared with healthy controls. However, the ability to increase the frequency of contractions is impaired when stressed by hyperthermia. Lymph vessels in Fontan patients were unable to respond usually. The participants were only able to increase the frequency of contraction twice during stress, compared to a five-fold increase among healthy controls. At the microcirculation level, Fontan patients filtered less fluid into the capillaries interstitial space than healthy controls at venous occlusion pressure. Studies carried out at InCor/HCFMUSP demonstrated that supervised aerobic exercise training improves the functional capacity and neurovascular control in Fontan patients compared to the non-training control group. However, the effect of aerobic exercise and light muscle resistance performed through online rehabilitation has not yet been demonstrated in peripheral lymphatic function and microcirculation. Aim: Evaluate the effects of an aerobic and light muscle resistance exercise program on peripheral lymphatic function, capillary filtration, functional capacity, and quality of life in adults with Fontan circulation. Methods: The function of the superficial lymphatic vessels in the lower leg will be investigated during rest in supine and standing positions, using near-infrared fluorescence imaging using Indocyanine Green (ICG; Verdye, Diagnostic Green GmbH, Germany). The variables analyzed are contraction frequency (contraction/minute), pumping Pressure (mmHg), and packet velocity. Venous congestion plethysmography will perform to analyze the capillary filtration and cardiopulmonary exercise test for functional capacity. The quality of life will be evaluated using the SF-36 Short-Form questionnaire. Expected results: the physical training improves peripheral lymphatic function, capillary filtration, functional capacity, and quality of life in patients with biventricular compared to the control group (no exercise training)
The goal of this interventional study is to compare training for different numbers of days each week in healthy, young individuals. The main questions it aims to answer are: - Does exercising less often improve endurance fitness as much as exercising more often? - Are endurance fitness improvements caused by improvements in the muscle and blood? Participants will train on a stationary bike for eight weeks. Researchers will measure the participants endurance fitness, as well as muscle and blood characteristics, before and after training to look for improvements from the training protocols. Researchers will compare low-frequency exercise (two times per week) and high-frequency exercise (four times per week) to see if they each improve endurance fitness.
Pilates training, a type of mind and body exercise that focuses on muscle strength and flexibility, has become increasingly popular in recent years. Research has shown that Pilates could be an effective exercise form to improve body composition, particularly in obese individuals, while beneficial effects on flexibility, muscular strength, and muscular endurance have also been observed in young and older adults. It is well documented that protein supplementation can augment the effects of resistance training on body composition and performance. While there is an abundance of studies investigating the effect of protein supplements on adaptations to resistance exercise, there is a knowledge gap regarding their effectiveness in Pilates training. The aim of this research is to investigate the effects of protein supplementation, compared to placebo (maltodextrin) on body composition, performance, and biochemical indices in healthy young and middle-aged, eumenorrheic (regular menstrual cycle) women who perform Pilates. Participants will be randomly assigned to receive either 0.6 g of whey protein or maltodextrin per kg body weight per day for 10 weeks. Participants will be asked to avoid modifying their dietary habits for the duration of the study to limit the effect of diet on the measured parameters. To check for this, participants will record their diet for 3 days (2 weekdays and one weekend day) on the first, middle, and last weeks of the intervention. Dietary records will then be analyzed. Pilates classes will be performed at least two times per week, while specialized Pilates equipment (Reformer or Cadillac) will be used according to the Pilates principles. The duration of each workout will be set at around 50 min. Participants will undergo measurements of body composition, core muscle endurance, and joint flexibility at the beginning and end of the study. In addition, hematologic parameters, clinical chemistry parameters, hormones, and plasma amino acids will be measured. All these outcome measures will be compared between the whey protein and maltodextrin groups to determine the effectiveness of protein supplementation in Pilates training.
Guayusa extract is a caffeinated Amazonian 'super-leaf' belonging to the holly species that contains a very unique blend of polyphenol antioxidants and caffeine (~20% caffeine, 30% chlorogenic acids, 5% catechins). It is also remarkably low in tannins which are responsible for the bitter taste found in most teas - giving it a sweet flavor profile. As such, it is marketed as an ingredient that can help support energy and performance with potential health-related benefits due to its antioxidant properties. Indeed, ingredients such as these are often consumed by individuals prior to exercise in order to help improve exercise performance, or otherwise to support health-related goals. Whereas several studies have suggested that caffeine and chlorogenic acid consumption may improve performance, mood, and concentration, and some evidence in animals have linked catechin consumption to improved health outcomes, no studies have previous studied whether guayusa extract supplementation helps to support exercise performance in humans. In this study, we will test the whether dietary supplementation with the botanical organic guayusa extract helps support (1) the desire to exercise and exercise performance throughout a 6-week high intensity exercise training program, and thus (2) helps support the physiological adaptations (including body composition, fasting metabolic biomarkers, blood pressure and heart rate, submaximal and maximal exercise performance and fuel metabolism, and changes in the gut microbiome/mycobiome) to a 6-week high intensity exercise training program. Question 1: Does organic guayusa extract supplementation support the desire to train and training load in physically-active women performing a high-intensity exercise training program? Question 2: Does organic guayusa extract supplementation support physiological adaptation to exercise (including body composition, fasting metabolic biomarkers, blood pressure and heart rate, submaximal and maximal exercise performance and fuel metabolism, and changes in the gut microbiome/mycobiome) in physically-active women performing a high-intensity exercise training program?
Our study aims to decrease independence by increasing upper extremity strength and performance by applying blood flow restrictive training, which has entered the literature as a new method, to the upper extremity in the elderly. The application will only be applied to the upper extremity and will last for 6 weeks.
Recent studies have shown that polarized training (i.e. the combination in the same session of intermittent high intensity exercise training, consisting of repeated, short-duration, high-intensity exercises on a cycle ergometer or a treadmill, and moderate exercise) can encourage the participation of obese people in body weight reduction programs, providing more dynamic exercises, less tiring and therefore more acceptable. To date, no data are available on the effects of polarized exercise in the rehabilitation of obese adolescents, who are often unwilling to engage in prolonged and monotonous motor activities. The demonstration that the polarized exercise might encourage the participation of obese adolescents in multidisciplinary body weight reduction programs, improve the cardiovascular capacity and also favor an adequate oxidation of lipids during the phase of exercise and post-exercise rest, could support its prescription in the programs of integrated metabolic rehabilitation of adolescent obesity.
Ageing in humans is accompanied by a progressive decline in lower-limb muscle power production. In addition to a decline in musculoskeletal fitness, ageing is associated with a reduction in cardiovascular and metabolic fitness. Therefore, if exercise interventions aim for a high impact on the overall health status of middle-aged and older adults, they should combine endurance, high-intensity interval training and muscular strengthening activities. Recreational football training combines all these training components, which implies that it could constitute an adequate training modality for participants of all ages. What remains to be investigated in more detail, is whether recreational football training can improve muscle power production in middle-aged to older adults and whether this potential improvement is present across the full force-velocity (F-V) profile. Next to a detailed analysis of the leg-extensor F-V profile as primary outcome, simultaneous effects on functional capacity, body composition and endurance exercise capacity were investigated. In addition, feasibility and the physical demands (internal and external load indicators) of the training program were tracked throughout the intervention period.
The research project is aiming to examine the muscular adaptations to resistance training (RT), detraining (DT) and repeated RT (i.e. retraining). The research project will also examine differences in muscular adaptations between 20 weeks of continuous RT and 20 weeks of intermittent RT including a 10-week DT period in the middle of the training intervention. This is randomized controlled trial in which the research participants will be randomized into discontinuous and continuous groups (both n=~20). Both will be doing a 2-3-week familiarization and control period at the start. Then in the former there will be an initial strength training period (10-wks), a DT period (10-wks), and a second strength training (retraining) period (10-wks). The second group includes a 10-wk non-training control period (10-wks) followed by a RT period (20-wks). Participants will be young, healthy men and women (age 18-35, which 50% are females) with no systematic RT experience during the last 6 months. Measurements will be completed before and after each study period. Body composition will be measured via bioelectrical impedance analysis (BIA) and 3D body scans. Dynamic leg press and elbow flexion one repetition-maximum (1RM) will be used to test maximal strength. Anaerobic performance and strength endurance will be tested in elbow flexion and dynamic leg press using RM tests. Vastus lateralis (VL) and biceps brachii muscle cross-sectional area (CSA) will be assessed via ultrasound. Muscle biopsies of the VL muscle will be obtained to assess changes in muscle fiber morphology and factors regulating and associated with the hypertrophic processes and metabolism. Blood samples will be collected to analyze changes in metabolism and physiology. A rating of perceived exertion (RPE) during training will be collected after every exercise to ensure proper training intensity. Finally, nutrition and habitual physical activity will be assessed with 4-day diet diaries and physical activity questionnaires before the intervention and during each 10-week period.
