Fatigue-induced changes in electromyographic activity after repeated racing turns: a pilot study.

Purpose: Alpine skiing races are physically demanding events characterized by numerous repeated near-maximal activations of the lower limb muscles. Although this type of task is known to induce neuromuscular fatigue, electromyographic activity (EMG) adaptations after repeated maximal-intensity skiing have not been previously investigated.

Methods: Six skiers completed a 6-turns section with (FAT) and without performing 30 giant slalom (GS) turns (CONT).

Singular case report of familial hypocalciuric hypercalcemia: a rare diagnosis of hypercalcemia in the older people.

Objective: to report a case of familial hypocalciuric hypercalcemia (FHH) in an older patient and highlight the diagnostic challenges in geriatric populations.

Case Presentation: We report the diagnosis of FHH in an 88-year-old polypathological patient with hypercalcemia discovered during a check-up for cardiac decompensation. Despite a confusing clinical presentation with gout symptoms, including repeated episodes of knee arthritis, persistent hypercalcemia conducted further investigations.

Effect of Midsole Hardness on Soft Tissue Vibrations: An Ascendant Hierarchical Clustering on 133 Runners.

Soft tissue vibrations (STV) can generate discomfort during running. Recent research has shown that footwear affects the amplitude of STV differently across runners but no studies have linked human characteristics and footwear construction yet. The purpose of this study was to investigate the runner specific STV responses to various midsole hardness and to identify functional groups, that is, groups of runners responding similarly to a given intervention.

Accelerated Red Blood Cell Turnover Following Extreme Mountain Ultramarathon?

Introduction: Mountain ultramarathon induces extreme physiological stress for the human body. For instance, a decrease in total hemoglobin mass (Hbmass) due to severe hemolysis is historically suspected. Nevertheless, hematological changes following a 330-km mountain ultramarathon have to date never been investigated.

Snow sports-specific extension of the IOC consensus statement: methods for recording and reporting epidemiological data on injury and illness in sports.

The International Olympic Committee's (IOC) consensus statement on 'methods for recording and reporting of epidemiological data on injury and illness in sport' recommended standardising methods to advance data collection and reporting consistency. However, additional aspects need to be considered when these methods are applied to specific sports settings. Therefore, we have developed a snow sports-specific extension of the IOC statement to promote the harmonisation of injury and illness registration methods among athletes of all levels and categories in the different disciplines governed by the International Ski and Snowboard Federation (FIS), which is also applicable to other related snow sports such as biathlon, ski mountaineering, and to some extent, para snow sports.

Pleasantness makes a good time: musical consonance shapes interpersonal synchronization in dyadic joint action.

Introduction: Music making is a process by which humans across cultures come together to create patterns of sounds that are aesthetically pleasing. What remains unclear is how this aesthetic outcome affects the sensorimotor interaction between participants.

Method: Here we approach this question using an interpersonal sensorimotor synchronization paradigm to test whether the quality of a jointly created chord (consonant vs.

Effect of Footwear Longitudinal Bending Stiffness on Energy Cost, Biomechanics, and Fatigue During a Treadmill Half-Marathon.

Introduction: Carbon plates have been used to increase running shoes' longitudinal bending stiffness (LBS), but their effect during a long duration run remains unknown. Our study aimed to identify the effect of LBS on energy cost of running (Cr), biomechanics, and fatigue during a half-marathon.Methods: Thirteen well-trained male runners (half-marathon time < 1 h40) performed two half-marathons at 95% of the running speed associated with their second ventilatory threshold on two separate visits, with either high-LBS shoes (HLBS, with carbon-plates) or standard-LBS (SLBS) shoes.

-related myopathies: clinical, myopathological and genotypic spectrum in a multicentre French cohort.

Background: Myosin heavy chain 7 ()-related myopathies (-RMs) are a group of muscle disorders linked to pathogenic variants in the gene, encoding the slow/beta-cardiac myosin heavy chain, which is highly expressed in skeletal muscle and heart. The phenotype is heterogeneous including distal, predominantly axial or scapuloperoneal myopathies with variable cardiac involvement.

Methods: We retrospectively analysed the clinical, muscle MRI, genetic and myopathological features of 57 patients.

The Effects of Heat Therapy During Immobilization and Rehabilitation on Muscle Atrophy and Strength Loss at Return to Sports in Healthy Humans.

Background: Animal research suggests that repeated heat exposures may stimulate skeletal muscle protein synthesis and downregulate protein degradation.

Hypothesis: Repeated heat exposures during ankle immobilization and rehabilitation would preserve human muscle strength and mass.

Study Design: Controlled laboratory study.

Decoding Ultramarathon: Muscle Damage as the Main Impediment to Performance.

Distinct and additive effects of visual and vibratory feedback for motor rehabilitation: an EEG study in healthy subjects.

Introduction: The use of visual and proprioceptive feedback is a key property of motor rehabilitation techniques. This feedback can be used alone, for example, for vision in mirror or video therapy, for proprioception in focal tendon vibration therapy, or in combination, for example, in robot-assisted training. This Electroencephalographic (EEG) study in healthy subjects explored the distinct neurophysiological impact of adding visual (video therapy), proprioceptive (focal tendinous vibration), or combined feedback (video therapy and focal tendinous vibration) to a motor imagery task.

Joint kinematic responses of Olympic medallist skiers to repeated slalom runs.

This case study aims to examine changes in the lower limb joint kinematic profile and performance stability induced by repeated ski runs in two world-class alpine skiers. Two Olympic medallist alpine skiers were tested during their slalom training, with continuous recording of right knee and hip angles, along with turn time and run time. The eight runs of the training session were analysed with linear mixed models.

The Dose-Response Relationship of an Exercise-Based Injury Prevention Program: A Secondary Analysis of a Randomized Controlled Trial on Athletics (Track-and-Field) Athletes Over a 39-Week Follow-Up.

Despite exercise-based injury prevention programs (EIPPs) being widely researched and used, several randomized controlled trials (RCTs) have failed to show their protective effect on injury risk. This is potentially due to underappreciating the EIPP dose-response relationship, by not controlling the analysis for the injuries sustained during the early EIPP implementation period, before the EIPP becomes efficacious. To determine the dose-response relationship of EIPP by controlling for the effects of injuries sustained before it became efficacious.

Methods: We conducted a study with data collection of: 1) national medical teams, 2) injury and illness complaints during the four weeks preceding the championships using an online pre-participation health questionnaire, and 3) newly incurred in-championship injuries and illnesses collected by national medical teams and the local organising committee using daily standardised online report forms, for all registered athletes at the championships.

Quadriceps Activation After Anterior Cruciate Ligament Reconstruction: The Early Bird Gets the Worm!

Arthrogenic Muscle Inhibition (AMI) is a phenomenon observed in individuals with joint injury or pathology, characterized by a reflexive inhibition of surrounding musculature, altered neuromuscular control, and compromised functional performance. After anterior cruciate ligament reconstruction (ACLR) one of the most obvious consequences of AMI is the lack of quadriceps activation and strength. Understanding the underlying mechanisms of AMI is crucial for developing effective therapeutic interventions.

French National Protocol for diagnosis and care of facioscapulohumeral muscular dystrophy (FSHD).

Facioscapulohumeral muscular dystrophy (FSHD) is one of the most common genetically inherited myopathies in adults. It is characterized by incomplete penetrance and variable expressivity. Typically, FSHD patients display asymmetric weakness of facial, scapular, and humeral muscles that may progress to other muscle groups, particularly the abdominal and lower limb muscles.
