Filter by:Physical exercise is an effective tool for the prevention of various chronic diseases. Fibromyalgia (FM) is a common chronic pain condition, in which patients may also experience a variety of other symptoms, including sleep disturbances, fatigue, stiffness, frequent episodes of pain and mental health problems, as well as possible gastrointestinal disorders. Furthermore, according to the American College of Rheumatology, such a generalised non-joint pain state occurs for at least three months in duration, predominantly in women over 50 years of age. In turn, chronic fatigue syndrome (CFS) presents as a disease characterised by persistent and debilitating fatigue lasting at least six months. The origin of FM and CFS is unknown, although alterations in the central nervous system (CNS), as well as abnormalities in muscle physiology and immune/inflammatory response are suggested as the main causes. In addition, most patients with FM are sedentary and in poor physical condition, exacerbated by pain, fatigue or depression, which can limit their daily activities and affect their quality of life and work opportunities. In this regard, physical exercise is considered the most important non-pharmacological strategy for the treatment of FM; however, many clinically relevant questions remain unanswered regarding the most effective approach to exercise therapy in FM patients. Therefore, the main objective of this project is to analyse the possible physical and mental benefits of a physical exercise programme in people diagnosed with fibromyalgia and/or chronic fatigue syndrome.
There are few studies in the literature that have evaluated the effects of using percutaneous stimulation of the auricular branch of the vagus nerve for sports purposes (to accelerate recovery after physical exertion). It has been demonstrated that tVNS in athletes improved the rate of heart rate recovery, reduced lactic acid levels in blood plasma, reduced pain, reduced overtraining syndrome and fatigue levels.
To gain a comprehensive understanding of the biomechanical behaviour of human heart to explore the concept of myocardial fatigue in response to a temporal range of preload, afterload and drug-induced inotropy using in-vitro contractile assays.
Overloading is a key training principle used by athletes and coaches to improve physical performance. Intensified training periods are therefore commonly incorporated into the course of a regular training season. From a clinical point of view, very intense periods of training are associated with a temporary immunological deficiency which can lead to teh "overreaching syndroms". During periods of overreaching, nutritional strategies are mainly aimed at ensuring sufficient amounts of energy to support the increase in effort. However less is known about nutritional supplements to attenuated the inflammatory/immunological response to training stress. Probiotic bacteria are defined as live food ingredients beneficial to the host's health. Numerous health benefits have been attributed to probiotics, including effects on gastrointestinal tract function and disease, immune function, hyperlipidemia, hypertension, and allergic conditions. Studies in the literature on the ergogenic effect of probiotics in athletes are still scarce today. this study aims to explore the potential role of probiotics on performance, recovery from fatigue and immune function during intensive period of training.
The purpose of this study is to assess the efficacy of dynamic tape in prevent shoulder muscle fatigue.
Musculoskeletal injuries amongst surgeons are prevalent. This project will determine whether Robotic-assisted Laparoscopic surgery (RALS) offers superior benefits to surgeon's musculoskeletal health than standard laparoscopic surgery (LS), by identifying the comparative changes in muscle fatigue during RALS Vs LS surgical procedures, and additionally identify any cognitive effects of this. The Study if successful, could help reduce injury rates in surgeons.
The aim of the study is to test a Fasting Mimicking Diet (FMD) for its efficacy on improving muscular resistance and endurance. The investigators will perform a randomized clinical trial to test the efficacy of the FMD on improving muscular strength, muscular resistance and endurance in physically active young adults (18-40 years of age). The study will include two arms: Placebo (Placebo diet) and FMD (3 cycles of 5-day fasting-mimicking diet within two months). Study endpoints will include muscular strength evaluation of lower limbs, cardio-pulmonary responses, neuromuscular function and muscle architecture. Subjects will be evaluated 4 times within 3 months: at baseline (T1), after the 1st cycle of diet (T2), 7 to 15 days after the 3rd cycle of diet maintaining baseline intensity (T3) and with re-assessment of Peak Power Output (T4).
What are the implications of wheelchair propulsion-induced fatigue for the development of shoulder pain and how can this knowledge improve prevention programs? With this project, the "Shoulder Health and Mobility group" of the Swiss Paraplegic Research in Nottwil (Switzerland) wants to investigate how fatigue during wheelchair propulsion affects risk factors for shoulder pain of persons with a spinal cord injury (SCI). The investigators want to find out how the handrim wheelchair propulsion technique changes with fatigue and want to define persons who are susceptible to fatigue. Getting life back after a SCI will most likely occur with the help of a wheelchair, whether it is at the beginning of rehabilitation or throughout further life. Gaining back mobility and participation in social life is important, also because of the multiple positive effects of physical activity on person's health and self-esteem, preventing several chronic diseases. Therefore, it is needed to try to stay away from shoulder injuries. Since the shoulder is very mobile and thus unstable, the joint is at increased risk for injuries. This is reflected in the high amount of persons with a SCI having shoulder pain (between 30 to 70 %). Once pain or an injury occurred, it is hard to recover, as so far no effective treatment is available. Several factors as gender, weight, age, level and completeness of the SCI, movement patterns and muscle strength were found to be related with injury and pain. However, it is currently not well understood what exactly causes shoulder injuries. Handrim wheelchair propulsion is an inefficient mode of propulsion and asks a lot of demands to the upper body. Because of the inefficient movement and the shoulder being prone to injuries, wheelchair propulsion has a high chance of inducing shoulder injuries and pain. Propelling with a technique minimizing the loads on the shoulders and improving the capacity to perform these movements (as increasing muscle strength) is of utmost importance as these factors can be modified by training. Previous intervention programs have learned wheelchair users to propel with long and smooth strokes aiming to reduce the loads. Although someone might be aware of the recommended techniques and can apply them, propulsion technique might change with fatigue and could become less optimal. A similar phenomena happens for example in landing strategies from a jump. In a fresh state, persons will try to have a stable landing reducing the impact on the lower limbs. With fatigue, however, there will be a tendency to forget about the proper landing technique which on its turn can increase the risk of injuries. This was suggested to be one of the reasons why there is an increased prevalence of injuries towards the end of a game. So far, it is unclear how fatigue alters propulsion technique and how these changes are related with an increased risk of shoulder pain. Tis project aims to achieve the goals by investigating how very strenuous wheelchair propulsion (fatigue intervention) of 15 minutes alters the propulsion technique of 50 persons with a SCI. All participants will perform the fatigue protocol in the movement analysis lab at the Swiss Paraplegic Research. During the protocol, participants will be requested to perform as many 8 loops as possible with their wheelchairs, including starts, stops, and right and left turns. Before and after the protocol, movement patterns, muscle usage and loads during wheelchair propulsion and the characteristics of the shoulder muscle tendons during rest will be assessed. Furthermore, the person's characteristics, such as weight, age, gender, time since injury, injury level, health conditions, use of medication, muscle strength and activity levels will be assessed. All these factors might be associated with the susceptibility to fatigue. To answer our questions, we will first compare the propulsion technique (movement patterns, loads, and muscle usage) before and after the protocol to investigate the direct effect of fatigue. Secondly, we will investigate the association of negative changes in tendon appearance (which has been related to injury) with the changes in the propulsion technique to investigate the implications of acute changes that might increase the risk of injury. Finally we will run a model including all variables to determine which person's characteristics are associated with an increased susceptibility to fatigue. The results will be highly relevant as it will give answers about the content, the aims and the target population of prevention programs for shoulder injury, aiming to improve mobility, participation, and quality of life in persons with SCI.
