Study Design Controlled laboratory study with repeated measures. Background Delayed-onset muscle soreness (DOMS) is one of the most common reasons for impaired muscle performance in sports. However, little consensus exists regarding which treatments may be most effective and the underlying mechanisms are poorly understood. Objectives To investigate the influence of compression garments on the development of DOMS, focusing on changes in muscle perfusion and muscle stiffness. Methods Muscle perfusion and stiffness, calf circumference, muscle soreness, passive ankle dorsiflexion, and creatine kinase levels were assessed on participants before (baseline) a DOMS-inducing eccentric calf exercise intervention and 60 h later (follow-up)...

Synopsis Patients with low-back pain have been shown to display differences compared to healthy individuals in all aspects of trunk motor control, most often studied as differences in muscle activity and kinematics. However, differences in these aspects of motor control are largely inconsistent. We propose that this may reflect existence of two phenotypes, possibly the two ends of a distribution, one with "tight" control over trunk movement and one with "loose" control. Both may have beneficial effects, with tight control protecting against large tissue strains from uncontrolled movement and loose control protecting against high muscle forces and resulting spinal compression...

OBJECTIVES: While previous studies have demonstrated an ergogenic effect of sport compression garments in exercise performance and recovery, the possible underlying mechanisms remain unclear. Claims for improved venous return from wearing sport compression garments with a low compression pressure remain unproven. The aim of this study was to determine the pressure profile exerted by low-pressure sports compression tights, and to investigate using a non-invasive Doppler ultrasound cardiac output monitor (USCOM), whether the compression applied will influence haemodynamic responses during an orthostatic challenge...

We report an exceptional clinical case of an ipsilateral dislocation fracture of the shoulder and right elbow, realizing a "swinging arm". Following a violent road accident, patient S.I, a 43-year-old left-handed sports educator, presented with an antero-medial shoulder dislocation fracture and a posterolateral ipsilateral elbow fracture-dislocation. The reduction in urgency, followed by the orthopedic compression by Mayo Clinic and functional rehabilitation, allowed obtaining a good result after seven months...

PURPOSE: Speed skating leads to blood-flow restriction and deoxygenation in the lower limbs (especially the right leg) that may affect performance. Although the acute influence of such deoxygenation is not clearly understood, we tested whether remote ischemic preconditioning (RIPC) could modify muscular oxygenation and improve time-trial performance in that sport. METHODS: Using a randomized, single-blind, placebo-controlled, crossover design, 9 elite speed skaters performed 1000-m on-ice time-trials preceded by either RIPC of the upper limbs (3x5-min compression/5-min reperfusion cycles at 30 mmHg > arterial systolic pressure) or SHAM (10 mmHg)...

Magnesium has been trending of late in automobile, aerospace, defense, sports, electronic and biomedical sectors as it offers an advantage in light-weighting. In aluminum, titanium, and steel dominated aerospace and defense sectors, applications of Mg were banned/restricted until recently due to perceived easy ignition and inability to self-extinguish immediately. Strength is generally inversely related to ductility, weak texture and unrelated to ignition resistance, making it challenging to optimize all four concurrently in a material...

BACKGROUND: Head-first impacts with an aligned cervical spine cause some of the most severe types of injuries due to the risk of fractures and associated spinal cord injury. Sports, such as football, mountain biking and horseback riding, contribute to the incidence of spinal cord injury but there is potential to reduce the risk of these injuries through a helmet-mounted device. METHODS: A novel device, the Pro-Neck-Tor mechanism, was incorporated into a commercial football helmet and tested in head-first impact experiments...

BACKGROUND: Although compression garments are used to improve sports performance, methodological approaches and the direction of evidence regarding garments for use in high-intensity exercise settings are diverse. OBJECTIVES: Our primary aim was to summarize the association between lower-limb compression garments (LLCGs) and changes in sports performance during high-intensity exercise. We also aimed to summarize evidence about the following physiological parameters related to sports performance: vertical jump height (VJ), maximal oxygen uptake (VO2 max), submaximal oxygen uptake (VO2 submax), blood lactate concentrations ([La]), and ratings of perceived exertion (RPE, 6-20 Borg scale)...

OBJECTIVES: The aim of the current study was to determine the effects of education with targeted or sham exercise on pain and function in postmenopausal women with greater trochanteric pain syndrome (GTPS). BACKGROUND: Conservative management of GTPS is poorly described, and to date, there have been no studies on education with exercise as an intervention for GTPS. Ninety-four postmenopausal women with GTPS were recruited to participate in this study. MATERIALS AND METHODS: Participants were randomized to receive one of two 12-week exercise programs (GLoBE vs...

INTRODUCTION: Popliteal artery entrapment is an uncommon syndrome, caused by extrinsic compression of the popliteal artery by muscular or tendinous structures. It occurs mainly in young individuals, with no atherosclerostic risk factors, and a mean age of presentation of 20 to 40 years, and has higher prevalence in males (83% of patients). Clinical presentation depends on the degree of arterial lesion, the most common being intermittent claudication, with critical ischemia being frequent...

Background: The treatment of humeral fractures remains controversial. Systematic reviews demonstrate similar results between dynamic compression plating and locked intramedullary nailing in the surgical treatment of these fractures. However, it appears that antegrade intramedullary nailing causes higher residual pain in the shoulder. The proposal of this work is to evaluate through the WORC protocol (Western Ontario Rotator Cuff Index) the consequences in the quality of life of patients submitted to osteosynthesis of the humerus with antegrade locked intramedullary nailing...

BACKGROUND: Although most anterior tibial stress fractures heal with nonoperative treatment, some may require surgical management. To our knowledge, no systematic review has been conducted regarding surgical treatment strategies for the management of chronic anterior tibial stress fractures from which general conclusions can be drawn regarding optimal treatment in high-performance athletes.

Background: The cause of heel pain among soccer players is multifactorial and is related to repetitive microtrauma due to impact forces involving technical moves, but also the playground, the exercise mode, the recovery time, the climatic conditions and the footwear used. Aim: To investigate the aetiology of plantar heel pain of soccer players with the objective of proposing an example of guidelines for treatment. Methods: We investigated the prevalence and characteristics of inferior heel pain of 1473 professional, semiprofessional and amateur players...

INTRODUCTION: Although the pathomechanism of isolated infraspinatus atrophy (ISA) in throwing sports is known to be traction, it is unclear why only some players are affected. One likely explanation is that the infraspinatus pulling force exerted by its contracture generate the compressive resultant component force (Fn) compressing the lateral trunk of the suprascapular nerve (LTSN) against the edge of scapular spine. This paper makes two key assumptions (1) the course of LTSN in relation to the scapular spine, defined as the suprascapular-scapular spine angle (SSSA) is the key individual anatomical feature influencing the Fn magnitude, and thus potentially ISA development (2) SSSA is correlated with scapular notch type...

Background: Ankle injuries account for up to 40% of all sport related injuries. These injuries can result in weeks to months of missed sport or work. The PRICE (Protection, Rest, Ice, Compression, Elevation) treatment is standard care for most acute ankle sprains. Recently, early mobilization in adults has been shown to decrease time off from sport or work, and the likelihood of developing chronic instability. To date, no research has been performed assessing the effectiveness of early mobilization in pediatric patients (<18 years)...
