Filter by:Ageing is characterized by a decline in neuromuscular control and a progressive loss of muscle mass, strength and power, leading to reduced mobility, loss of independence, higher hospitalizations rate, and increased all-cause mortality. Several studies suggest a non-linear decay of these age-related changes. Denervation-reinnervation processes, resulting in fewer but larger surviving motor units in advanced age, start as early as age 50-60yr and can be magnified in older adults (>75yr). Significant functional consequences in daily living activities are not usually observed until approximately 50yr. However, after 50yr, muscle strength/power reduction is accelerated and becomes faster than average muscle mass loss. Most observations come from cross- sectional studies and several confounding factors associated with secondary aging, such as physical activity levels, may contribute to (or compensate for) the observed age-related reductions in neuromuscular function. Compared to cross-sectional designs, prospective ones are advantageous in their ability to investigate fundamental mechanisms by excluding inter-subjects variability. In this project, the investigators will characterize longitudinal age-related changes in motor function, physical performance and muscle aerobic metabolism with an integrated approach. The investigators aim to combine classical methods of in-vivo and ex-vivo evaluation of neuromuscular function with innovative approaches for assessing changes and interactions between neural, structural and metabolic variables in two critical phases of ageing: 55-60yrs and 75-80yrs. Within each age-group, subjects will be classified based on their functional capabilities and divided in either active or sedentary. The investigators will describe the 2-yr time course of 1) mechanisms impairing neuromuscular function (denervation-reinnervation processes); 2) interactions between muscle structural changes and neural/metabolic impairments; 3) functional and metabolic changes occurring at whole muscle as well as single fibers level. The results will extend current understanding of physiological determinants of neuromuscular alterations in aging by identifying the course and rate of changes of specific factors that mediate functional loss and disability in older adults.
Movement screening tests to identify deficits or poor movement quality is commonly used in soccer and other sports to assess injury, to evaluate rehabilitation goals and return to sport after injury. Female soccer players have an increased risk of suffering a knee injury which can be related to a poor knee control. Knee control can be observed and assessed by the Single Leg Squat (SLS) test. The SLS test is reported to be reliable, but there still is an overall lack of clear evidence of the accuracy for tests used for assessing movement quality in sports medicine, and the discriminate and predictive validity of the SLS test in a female soccer cohort needs to be further investigated. It is also not clear what significance other physiological- psychosocial- and hormonal factors have for the outcome of the SLS and for injury. The overall aim of this project is to investigate if the outcome of a visually assessed SLS test can discriminate between individuals with a previous injury in the lower extremity, and if the outcome, separate or together with physiological-, psychosocial- and hormonal factors can predict future injury in a cohort of female soccer players. The authors hypothesises that the outcome of the SLS cannot discriminate between individuals with a previous injury in the lower extremity but that the outcome of the SLS, separate or together with physiological-, psychosocial- and hormonal factors can predict future injury in a cohort of female soccer players. 269 female soccer players (≥16 Yr.) from Damallsvenskan, Elitettan and division 1 in the area of Stockholm was enrolled in the study and baseline measurements were done during 2022-01-08 to 2022-02-21. The female soccer cohort will be followed during the season 2022 regarding injuries upcoming injuries.
Long-distance mountain running is increasingly popular among European and North America countries. Long-distance races are organized in various mountains and can reach up to 160 km (100 miles) with several thousands meters of climbing. The pathophysiological consequences of such extreme effort is still a matter a debate. From a muskelo-skeletal perspectives, the potential lower-limb join damage is a major health issue. The present study aims to use objective magnetic resonance imaging (MRI) techniques to describe the consequences of performing long-distance mountain running races on the knee cartilage.
This study is designed to compare the effect of Voxx/eSmartr technology on common measures of sports vision performance including (Hand-Eye Coordination/Reaction time, visual concentration and basic visual functions of size detection and contrast sensitivity). The study will be a randomized, prospective, double-blind design in order to determine the effect of this technology on a subject's sports vision ability.
Is it feasible to perform acupuncture in the training field after sport performance in adolescent football players? Does acupuncture provide a decrease in muscle soreness and improvement in overall sense of well-being in the adolescent football population?
