When are the use of B2 agonist anabolic agents justified?

So, we work in a field where strength based rehabilitation is paramount and in many conditions from Osteoarthritis to tendinopathy rehabilitation has been shown to be superior or at least as successful as surgical intervention yet we struggle with innovation. Studies dabble between concentric versus eccentric, slow versus fast and the trend flip flops between…

How do running mechanics change with fatigue?

Injury risk during running is associated with high-weekly training distance as well as lack of running experience, putting both competitive long-distance runners and novice runners at risk of developing overuse injuries. The development of overuse injuries has been associated with kinematic variables of all lower limb joints. Some of these variables, such as increased ankle…

Myotendinous junction & muscle fibers response to heavy resistance training

The myotendinous junction (MTJ) as the interface between muscle and tendon is known to be the weakest link in the muscle-tendon chain, and ultrasonographic visualization of muscle strain injury in humans indicates that tissue damage involves the MTJ. Microscopy of experimental load-to-failure strain injuries in animals has revealed that the actual site of rupture is…

Patellofemoral Pain: What do phenotypic features show?

Ninety percent of patients with patellofemoral pain (PFP), a chronic musculoskeletal disorder characterized by anterior knee pain, are still in pain 4 years after the initial diagnosis. Specialists have optimized management of other chronic musculoskeletal conditions by subgrouping patients based on risk factors. While previous studies aimed to categorize patients based on imaging studies, this…

How much does visual distraction effect torso position in side-stepping

An important steering task in team sports is cutting and side-stepping (SS), a maneuver performed to evade oncoming opponents. Sidestepping during game situations is complex, as athletes are generally traveling at higher velocities and often required to sidestep under unpredictably high temporal constraints when responding to opponents’ defensive movements or other situational demands. Frontal plane…

Does Bench Press improve performance in 50m swimming?

To improve strength and power, top-level swimmers commonly execute traditional strength exercises (i.e., bench press and squat) on dry-land. It is assumed that the training adaptations resulting from these nonspecific strategies are able to enhance swimming performance. Therefore, it is interesting to ascertain which dry-land testing and training methods provide results more closely related to…

How focussed does you warm-up need to be?

In my review this week is my summary of a paper looking at soccer warm ups. ( Sign up to get it each week) In most sports, a warm-up is performed with an aim to prepare the body for high level performance and to prevent injuries when performing at that high level. In soccer, players…

Intramuscular tendon : A hidden problem in Muscle tears?

It is well known that some hamstring and quadriceps strains take much longer to repair than others, and some injuries are more prone to recurrence. A number of thigh muscles including the biceps femoris and rectus femoris have significant intramuscular tendons. Improved resolution via MRI and anatomical dissection studies provide evidence that in many muscles,…
