Risk factors for, and prevention of, shoulder injuries in overhead sports: a systematic review with best-evidence synthesis

Risk factors for, and prevention of, shoulder injuries in overhead sports: a systematic review with best-evidence synthesis

admin Biomechanics, Blog, Competition, Injuries, Latest&Greatest, Training Leave a Comment

The burden of shoulder problems highlights the need for injury prevention strategies. Identifying risk factors and developing strategies to prevent injury, based on these risk factors, are key components for preventing injuries in sports. This reflects the second and third step in the ‘sequence of prevention’ and ‘translating research into injury prevention practice’ models. Overall, 4,740 studies were excluded from …

Troubleshooting Series: Cervical Spine Injuries in Swimmers

Dr. GJohn Mullen Biomechanics, Blog, Dr. John Mullen, Dryland, Injuries, Latest&Greatest, Training Leave a Comment

Troubleshooting Series: Cervical Spine Understanding cause-and-effect lies in the heart of effective movement correction, both in and out of the water. The better grasp we have of the body’s movement fundamentals, the more capable we can decipher the visual presentation of stroke flaws. The quotations around “flaws” are intentional, as the flaw that catches our attention on deck may be …

Dr. GJohn Mullen Allan Phillips, Biomechanics, Blog, Injuries Leave a Comment

1) Swimmers posture can heighten injury risk2) Stroke mechanics may be implicated by swimmers posture3) Swimmers posture can affect both land and water strength We all know what swimmers posture looks like but how can we actually describe it? Characteristics include forward head, rounded upper spine (kyphosis), elevated and protracted scapulae, anteriorly positioned humeral head, highly developed upper trapezius, and …

7 Ways to Reduce Swimming Low Back Pain

7 Ways to Reduce Swimming Low Back Pain

Dr. GJohn Mullen Biomechanics, Blog, Competition, Dr. John Mullen, Injuries, Training Leave a Comment

The shoulder is the primary site of injury in swimmers, but the low back is the second most commonly injured site. In fact, ~8% of those competing at a 2001 International competition experienced low back pain. Kaneoka (2007) noted thirty-eight (68%) elite swimmers and 11 (29%) controls had degenerated discs at various levels. Disc level L5-S1 was more frequently degenerated …

Do Schoolbags Cause Low Back Pain?

Do Schoolbags Cause Low Back Pain?

admin Blog, Injuries, Latest&Greatest Leave a Comment

There is variation regarding recommendations for children and adolescents carrying schoolbags. Guidelines for safe loads are mostly within 10%–15% of body weight (BW) range but include values as low as 5% and as high as 20%. Some biomechanical studies suggest that the schoolbag weight of 10% of BW may be enough to cause changes in kinematics, body posture and muscular strain. Methods of …

Shoulder Kinematics During Scapular Plane Abduction

Shoulder Kinematics During Scapular Plane Abduction

Dr. GJohn Mullen Blog, Dr. John Mullen, Injuries, Latest&Greatest Leave a Comment

Shoulder impingement is the most common injury in swimming. Many factors contribute to shoulder impingement and one is inadequate space for clearance of the rotator cuff tendons during arm elevation. Previous studies have analyzed healthy shoulder range of motion with single-plane radiographs, but did not provide 3-D motion of the shoulder. Three-dimensional analyzes are necessary to understand the activity in …

Posterior Capsule Tightness

Posterior Capsule Tightness

Dr. GJohn Mullen Blog, Injuries, Latest&Greatest Leave a Comment

Posterior shoulder tightness is common in patients with shoulder injuries. The shoulders are the most commonly injured site in swimmers, suggesting swimmers have tight posterior shoulders. It is believed the posterior capsule is responsible for the tightness in the posterior shoulder, leading to the glenohumeral internal rotational deficit (GIRD) and type 2 superior labrum anterior and posterior (SLAP) lesions, the …

Neuromuscular Response to Pain and Exercise Induced Muscle Damage

Neuromuscular Response to Pain and Exercise Induced Muscle Damage

Dr. GJohn Mullen Blog, Dr. John Mullen, Injuries, Latest&Greatest Leave a Comment

Muscle soreness and pain are common sensations following a bout of unfamiliar exercise. This is believed secondary to lengthening and damage of the muscle fibers resulting in inflammation. Moreover, this damage results in changes in neuromuscular function and force production. Surprisingly, this decrease in force is not seen until 12 hours following exercise, perhaps due to pain not occurring until …
