As humans age, there is a gradual loss of skeletal muscle mass and strength, termed sarcopenia. The underlying causes of sarcopenia are yet not fully elucidated but are thought to be multifactorial and include increased levels of systemic pro-inflammatory mediators, a decrease in anabolic hormones and changes in the neuromuscular system. Furthermore, physical inactivity, chronic diseases, immobilisation and hospitalisation are known to play an important part in the development of sarcopenia. The prevalence of sarcopenia ranges from 20-30% (aged >70yrs) within the general community. However, the prevalence of sarcopenia in geriatric patients after an acute hospital admission is substantially higher, estimated at ≈50%. Furthermore, successive events of hospitalisation have been suggested to contribute to the development of sarcopenia, as even short periods (4-5 days) of skeletal muscle disuse are known to induce muscle atrophy. Mean length of hospital stay in geriatric wards due to acute illness or hip-fracture is typically 7 to 11 days during which the level of physical activity is strongly reduced leading to an accelerated loss of muscle mass that many older patients never recover from. Notably, a substantial part of the deterioration in functional capacity could be avoided just by counteracting loss of muscle mass during hospitalization. As such, we need to identify sensitive biological, clinical and functional biomarkers predicting loss of muscle mass and function during hospitalization to identify patients at risk of developing sarcopenia. Additionally, it is crucial to investigate the association of these biomarkers with hospital length of stay, as hospitalisation has been suggested to contribute to the development of sarcopenia while longer hospital stays may increase patient risk of hospital-acquired infections and place an economic burden on society.
The research project explores how non-invasive brain stimulation can be used to detect and ameliorate loss of muscle strength after inactivity. At present, there is a limited understanding of how to maintain muscle strength during inactivity. Increasing evidence indicates that reduction in muscle strength following immobilisation is associated with reduced cortical motor output. Therefore, the aim of the study is to test if brain stimulation, can maintain cortical motor output and ameliorate the loss of muscle strength following immobilisation.
This study aims to investigate the muscle anabolic potential of adding ketone (3-hydroxybutyrate) to whey protein compared with isocaloric, isonitrogenous whey protein in a human model of inflammatory catabolic disease. Further, this study aims to investigate whether the same amount of whey protein has different effects on muscles in an catabolic inflammatory setting compared with a healthy setting.
This is a prospective, single center study conducted at the University of Pittsburgh designed to test the applicability and utility of XenMatrix™ AB Surgical Graft in the restoration of function in the setting of volumetric muscle loss after soft tissue trauma.
Whether higher dietary protein benefits skeletal muscle health in older adults remains an ongoing area of investigation. This study will determine whether adding an alkaline salt supplement, potassium bicarbonate, to reduce the dietary acid load of a high protein diet can further enhance the beneficial impact of a high protein diet alone on muscle performance and mass in older underactive adults on baseline low protein diet.
Introduction: The improvement of strength affects muscle volume, dynamic stability and sports performance in water polo athletes. Plyometric exercises can improve biomechanics, performance and the most explosive actions during sports. The work done with elastic bands will increase the effectiveness and the resistance on the isometric exercises developed. Objectives: To evaluate the effectiveness of plyometric exercises in the increase of quadriceps muscle strength, volume and stability dynamic in female athletic of water polo players from 18 to 25 years old. Study Design: A randomized, multicentric, single-blind clinical study with a follow-up period. Methodology: 25 water polo players will be recruited and randomly assigned to the two study groups: experimental (plyometric exercises plus isometric exercises with elastic bands) and control (isometric exercises with elastic bands). The intervention will last for 8 weeks, with 3 weekly sessions, of 15 minutes each. The study variables will be: strength (measured with the RM test), muscle volume (using anthropometry), and dynamic stability (through the SEBT test). The analysis of normality will be carried out with the Shapiro Wilk test. In case of homogeneity of the groups, we will use parametric tests: t-student test of repeated measures (difference between evaluations) and ANOVA of repeated means (intra and intersubject effect). Expected Results: It is expected to observe improvement in muscle strength and quadriceps volume, as well as dynamic stability.
The purpose of the study is to describe the change in muscle mass in critically ill patients. The study will examine rectus femoris cross sectional area with ultrasound and identify risk factors of this changes.
