Purpose: The application of horizontal resistance is key in sprint training to modulate velocity and promote adaptations. However, the interaction between velocity and resistance on muscle excitation remains insufficiently studied. This study assessed the electromyographic (EMG) activity of thigh and gluteal muscles in response to varying velocity...

To assess how altitude training impacts force-velocity-power (F-V-P) profiling and muscular power and anaerobic capacity in elite badminton players in reference to intra- and inter-individual sex-based variability. Following a quasi-experimental design, 14 players (6 females, 8 males) from the French national badminton singles and doubles teams per...

INTRODUCTION: This study aimed to assess how altitude training impacts force-velocity-power (F-V-P) profiling and Win- gate test in elite badminton players in reference to intra- and inter-individual gender-based variability. METHODS: Fourteen players (6 females, 8 males) from the French national badminton doubles team performed a 3-week “living hi...

Background Various training programs aim to make athletes faster by using methods like sprinting with additional resistance. Given that sprint running is associated with a high risk of hamstring injuries, it is of major importance for injury prevention to assess the effect of such training on lower limb electromyographic (EMG) activity. Objective...

Background Psychological processes have been associated with the risk of sports injury. However, different psychological processes can be related to different injury characteristics based on their modes of onset, severity or number. Objective To cluster injury characteristics and identify the links with psychological processes in elite athletes pr...

Background Hamstring strain injuries (HSI) are prevalent in elite sports. Monitoring for (re-)injury prevention often includes tests such as the straight-leg-raise, reflecting the stiffness of all the tissues crossing the hip joint. Alternatively, ultrasound shear wave elastography (SWE) allows to assess the regional shear modulus (index of elastic...

Objective: To describe the epidemiology of injury complaints related to the athletics activity in elite athletics (track and field) athletes practicing disciplines with sprints (i.e., sprints, hurdles, combined events, long jump, and triple jump). Methods: We conducted a cross-sectional study on elite sprinting athletes licensed with the French Fed...

Background: Wearable resistance (WR) training is a modality that allows athletes to perform loaded sport-specific movements to develop force and power outputs. The acute responses by which WR works is still relatively unknown, and the effects of WR load and location of the load has not yet been examined. Objectives: To investigate the acute neur...

Purpose: The present study aimed at comparing knee extensor neuromuscular properties determined with transcutaneous electrical stimulation using two pulse durations before and after a standardized fatigue protocol. Methods: In the first sub-study, 19 healthy participants (ten women and nine men; 28 ± 5 years) took part to two separate testing se...

Background: Effects of long-term (>6 months) stretching in spastic paresis are unknown. Objective: To compare architectural and clinical changes in plantar flexors of patients with chronic hemiparesis following a oneyear daily self-stretch program vs standard rehabilitation. Methods: Twenty-three patients with hemiparesis (8W; age, 56(12), mean(SD)...

Objective The effects of long-term (> 6 months) stretching in spastic paresis are unknown. The objective of this study was to compare the architectural and clinical changes in plantar flexors in patients with chronic hemiparesis following a one-year daily self-stretch program vs. standard rehabilitation. Material/patients and methods Twenty-three...

Rowing races require developing high level of force and power output at high contraction velocity. This study determined the force-velocity and power-velocity (F-P-V) profiles of lower and upper limbs of adolescent rowers and their relationships with a 1,500-m rowing ergometer performance. The power developed during the 1,500-m (P1500) was evaluate...

Introduction L’effet de l’etirement a long terme chez des patients paretiques reste inexplore [1]. L’objectif est d’etudier les modifications des parametres architecturaux de l’unite musculotendineuse du soleaire et du gastrocnemien medial (GM) chez des patients hemiparetiques chroniques apres un an de reeducation. Materiel, population et methode V...

Objective To explore changes in muscle architectural parameters of the muscle-tendon unit of soleus and medial gastrocnemius (GM) in patients with chronic hemiparesis, after 1 year of rehabilitation. Material/Patients and methods In this prospective study, 20 chronic hemiparetic patients (8 W, mean age: 56 [12], time since lesion 9 [8]) were evalua...

Purpose: The aim of the present study was to determine whether the anaerobic performance assessed by a modified Wingate test could account for the 1,500-m rowing ergometer performance in young competitive rowers. Methods: Fourteen national-level adolescent rowers performed on a rowing ergometer i) a 30-s all-out exercise (i.e., modified Wingate...

Performance during human movements is highly related to force and velocity muscle capacities. Those capacities are highly developed in elite athletes practicing power-oriented sports. However, it is still unclear whether the balance between their force and velocity-generating capacities constitutes an optimal profile. In this study, we aimed to det...

La capacité d’un athlète à accélérer un objet ou son propre corps constitue un déterminant essentiel de la performance sportive dans de nombreuses disciplines. Cette qualité d’explosivité est liée aux limites mécaniques du système neuromusculaire et notamment à la puissance maximale que l’athlète est capable de produire. L’évaluation précise de ce...

This study aimed to evaluate the validity and test-retest reliability of trunk muscle strength testing performed with a latest-generation isokinetic dynamometer. Eccentric, isometric, and concentric peak torque of the trunk flexor and extensor muscles was measured in 15 healthy subjects. Muscle cross sectional area (CSA) and surface electromyograph...

This study determined the concurrent validity and reliability of force, velocity and power measurements provided by accelerometry, linear position transducer and Samozino’s methods, during loaded squat jumps. Seventeen subjects performed squat jumps on two separate occasions in 7 loading conditions (0% to 60% of the maximal concentric load). Force,...

This study aimed to investigate the coordination of lower limb muscles during a specific fencing gesture in relation to its mechanical effectiveness. Maximal isokinetic concentric and isometric plantarflexor, dorsiflexor, knee and hip extensor and flexor torques of 10 female elite saber fencers were assessed and compared between both legs.
