25-OH-VitaminD3 level in elite sports: Impact on muscle damage and infections

Summary: Muscle damage as well as recurrent and serious infections especially to the end of the playing period in team sport or to the end of preparation for competition in endurance or single sport are the most common symptoms in elite sport demolishing optimal training results. Are VitaminD deficiency responsible for these symptoms in elite sport.

Chronic Exertional Compartment Syndrome in Athletes: A narrative Review

Chronic exertional compartment syndrome of the lower leg accounts for approximately 75% of sports-related chronic leg pain. Nevertheless, the exact and timely recognition in athletes might pose a great challenge to sports physicians. Among a variety of possible differential diagnoses such as tenosynovitis, stress fractures, periostalgia, or popliteal artery entrapment syndrome the physician has to be able to identify the correct entity as promptly as possible.

Exercise induced Leg Pain due to Vascular Compression Syndrome

Within a sports medicine setting vascular pathologies of the legs represent a rare entity and are often associated with a significant delay of diagnosis and treatment. Nevertheless, timely detection is crucial when it comes to management of athletes.

Differential coordination behaviour between concentric and eccentric contractions – many questions remain unanswered

Concentric and eccentric muscle work is characterized through different biochemical activating cascades. Concentric contraction is characterized by an ATP O2 coupling dependent interaction of the myofibril proteins Aktin and Myosin. In eccentric contraction, according to the Winding-filament hypothesis, a rotation movement around the thin filament is caused which is ATP independent. In addition, the processes of motor anticipation vary greatly between the two. This leads to the aim of the study: What are the differences in concentric versus eccentric muscle work concerning anticipation, perception and execution.

Strength deficits of the hamstrings following surgery on the anterior cruciate ligament: a case-control study of elite alpine ski racers

Background: Research to date clearly shows that injuries to the cruciate ligaments are a frequent occurrence in alpine ski racing. The hamstrings play an important role in protecting the anterior cruciate ligament (ACL). Here eccentric muscle activity, in particular, is of great significance as it plays a more important role in terms of duration and intensity than concentric muscle activity in alpine ski racing. The aim of this study was to establish whether the hamstrings of alpine ski racers show eccentric strength deficits following surgery on the anterior cruciate ligament.

Rectus femoris muscle rupture – 2 case reports

Eine komplette Ruptur eines Muskelbauchs kann zu einem partiellen oder vollständigem Funktionsverlust führen. Dies gilt insbesondere für wichtige Kennmuskeln. Ein solcher Muskel ist der M. rectus femoris. Er ist der wichtigste Kniestrecker. Ein vollständiger Funktionsausfall des M. rectus femoris führt zu einem Extensionskraftsdefizit im Kniegelenk, ähnlich einer Patellarsehnen- oder Quadricepssehnenruptur. Während bei einer Patellarsehnen- oder Quadricepssehnenruptur therapeutisch die chirurgische Sehnenrekonstruktion unbestritten ist, ist dies für den Muskelriss weniger eindeutig. In den zwei Fällen, die hier vorgestellt werden, wurde der chirurgische Therapieweg gewählt.

Outcome of muscle injuries in youth football

Background: Muscle injuries are the most common injury in soccer and account for almost 30 percent of all time-loss injuries. The aim of this study was to investigate the muscle length as a risk factor to sustain a muscle injury and to grade and monitore muscle injuries during the rehabilitation. Methods: 110 young male football players of 5 soccer teams (U15, U16, U17, U18 and U21) with (age 16,8 (14,3–21) years, height 174,5 (146,1–190,0) cm, weight 65,7 (35,5–84,6) kg) were monitored for 12 months in a prospective cohort study. Initially, muscle length in all players were measured. Every muscle injury was documented and monitored in a standardized protocol and graded clinically based on the Muscle-Injury-Score.

The burden of muscle injuries in youth football

Background: Muscle injuries affect up to 72% of professional soccer players within one season and there are well reviewed, but muscle injuries in youth soccer players are not widely documented. The aim of this study was to investigate incidence, localization, pathomechanism and point of time of indirect muscle injuries in youth soccer players. Methods: Prospective cohort study. 5 teams (U15, U16, U17, U18 and U21) with 110 young male football players (age 16,8 (14,3–21) years, height 174,5 (146,1–190,0) cm, weight 65,7 (35,5–84,6) kg) were monitored for 12 months. Every muscle injury was documented and monitored on a standardized evaluation score.

Evidence-based Treatment of Muscle Injuries

Injuries to skeletal muscle can pose a severe challenge for any team physician or medical professional. They account for up to one third of all sports-related injuries and can result in weeks of recovery and absence from play. Crucial in the successful treatment is the accurate classification of the type of injury, be it fatigue, structural or chronic.

Diagnostics and classification of muscle injuries in sports

Muscle injuries are responsible for up to one third of the musculoskeletal injuries occuring in professional football and summer Olympic Games. Classifying injuries has the objective to define the extent, to predict the time-loss, and potentially to suggest a treatment plan to optimize the return to sport and prevent from re-injury.
