Article Synopsis
- - This study focuses on time-loss muscle injuries in young football players from the Italian Under-19 Championship, addressing the lack of research in this area compared to adult players.
- - Over the 2022-23 season, data from 391 players revealed 479 total injuries, with 44% being muscle injuries, predominantly affecting the hamstrings, quadriceps, adductors, calves, and iliopsoas, leading to significant time lost.
- - The findings indicate hamstring injuries are the most severe, causing nearly half the days lost due to muscle injuries, and highlight that injuries involving myo-tendinous or myo-aponeurotic areas result in a longer recovery time.
Purpose: To investigate the 90° change of direction (COD) task in an extensive cohort of competitive healthy football players within the CUTtheACL study and to provide normative values and differences between males and females for full-body kinematics based on two-dimensional (2D) video analysis and scoring system.
Methods: One-thousand-and-two competitive football (soccer) players (age 16.3 ± 2.
The aims of the current study were to determine the most demanding passages of match play (MDP) and the distribution of match activities relative to maximum intensities during official matches in top-class women soccer players. Twenty-eight women players competing in European championship and international UEFA competitions were monitored during 38 official matches (277 individual samples). Maximum relative (m · min) total distance (TD), high-speed running (HSRD), very high-speed running (VHSRD), sprint, acceleration and deceleration distances were calculated across different durations (1-5, 10, 15, 90 min) using a rolling average analysis.

Methods: Seventeen male professional water polo players were randomly assigned to assume 5 grams per day of L-Arginine ( = 9) or placebo ( = 8) for 4 weeks. The players' fitness level was assessed in the maximal speed swimming test.
Background: Rehabilitation of soccer players after anterior cruciate ligament reconstruction is usually performed without sport-specific guidelines, and the final phases are often left to the team coaches. The possibility of changing this approach has not yet been investigated.
Study Design: Case series.
Background: Patellofemoral lesions represent a very troublesome condition to treat for orthopaedic surgeons; however, second-generation autologous chondrocyte implantation (ACI) seems to offer an interesting treatment option with satisfactory results at short-term follow-up.
Hypothesis: Hyaluronan-based scaffold seeded with autologous chondrocytes is a viable treatment for the damaged articular surface of the patellofemoral joint.
Study Design: Case series; Level of evidence, 4.
Background: The anterior cruciate ligament has been shown to have poor healing ability, and reconstruction is the standard treatment.
Hypothesis: Primary anterior cruciate ligament repair combined with bone marrow stimulation could restore stability and function in athletes with acute anterior cruciate ligament incomplete tears.
Study Design: Case series; Level of evidence, 4.
A novel apparatus, composed by a controllable treadmill, a computer, and an ultrasonic range finder, is here proposed to help investigation of many aspects of spontaneous locomotion. The acceleration or deceleration of the subject, detected by the sensor and processed by the computer, is used to accelerate or decelerate the treadmill in real time. The system has been used to assess, in eight subjects, the self-selected speed of walking and running, the maximum "reasonable" speed of walking, and the minimum reasonable speed of running at different gradients (from level up to +25%).
