Background: Knee proprioception may be compromised after anterior cruciate ligament reconstruction (ACLR), but associated factors and impact remain unclear. This study evaluated knee proprioception 4 months after primary ACLR, compared with healthy controls, and explored the impacts of leg dominance, anterolateral procedures (AEAPs), and their association with psychological readiness to return to sports.
Methods: This prospective cohort study included 30 ACLR participants and 20 healthy controls.
Background: The mechanical properties of knee flexors muscles contribute to reducing anterior cruciate ligament loading. This case-control study evaluated the passive knee flexors stiffness after primary anterior cruciate ligament reconstruction with comparison of healthy controls.
Methods: After anterior cruciate ligament reconstruction, 88 participants (24.
Article Synopsis
- The study investigates the effects of a 20-week high-intensity strength training program on heart structure and function in 27 healthy young men, addressing a gap in research compared to endurance training.
- Participants underwent various strength training exercises three times weekly; evaluations included body composition, ECG, echocardiography, and exercise testing before and after training at 12 and 20 weeks.
- Results showed significant improvements in exercise strength without changes in BMI or fat mass, suggesting that strength training can enhance muscle performance without adversely affecting body composition.
Objectives: To assess the impact of preseason shoulder testing on the risk of significant shoulder injury (SSI) in elite badminton players.
Design: Prospective cohort study.
Setting: Secondary care, academic medical center.
Context: Overhead athletes place tremendous demands on the shoulder complex, which result in adaptive kinematics but potential susceptibility to injury. This study aimed to compare shoulder glenohumeral range of motion (ROM) and rotator muscles strength in bilateral and unilateral overhead sports.
Design: Cross-sectional study; secondary care.
Background: Strength limb symmetry index (LSI) is a useful criterion to help in return-to-sport performance (RTP) after anterior cruciate ligament reconstruction (ACLR).
Objectives: We aimed to assess whether knee extensor and flexor LSI values at 4 months after ACLR are associated with those recommended at 8 months after ACLR for RTP (80%, 85% and 90%) and with successful RTP after 2 years.
Methods: This was prospective cohort study of 113 participants who underwent primary ACLR.
Muscle strength imbalances between the internal and external rotators of the shoulder are frequent in swimmers, but their role in shoulder injury remains unknown. We aimed to evaluate the association of shoulder rotator strength and injury in elite adolescent swimmers. Eighteen adolescent swimmers performed preseason isokinetic tests of the internal and external rotator muscles in concentric (con) and eccentric (ecc) modes.

- The study aimed to analyze the frequency and types of injuries in elite badminton players throughout a competitive season at the French National Institute of Sport.
- A total of 35 injuries were recorded among 20 players over 10,210 hours of play, revealing an injury rate of 3.4 per 1000 hours, with a significantly higher rate during matches compared to training.
- The majority of injuries were lower-limb, particularly affecting the foot, and musculotendinous injuries were the most common, with incidents primarily occurring in the early stages of play.
