What is the Perfect Backstroke Body?

admin Biomechanics, Blog, Dr. John Mullen, Latest&Greatest Leave a Comment

Ideal body shape and structure is a common topic in swimming communities. It is most common for coaches to use their subjective eye when deciding if a swimmer has the perfect backstroke body (somatyape). A recent study by Sammoud (2018) assessed the key physical characteristics of young backstroke swimmers. The goal of this study was to determine what factors predict …

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 …

3 Reasons to Fix Swimmers Posture

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 …

How Repeated Stretches Affect Muscle Viscoelasticity

How Repeated Stretches Affect Muscle Viscoelasticity

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

Viscoelasticity is the ability to return of a material to return to a position after an extended force application. Dynamic tissues (muscles, tendons, ligaments) possess viscoelastic structures. The ideal mechanism and benefits of stretching are uncertain, but previous work suggests constant-torque is more beneficial than constant-angle for improving muscle creep, resulting in a decrease in stiffness. This creep is the …

Kinematics of the Thoracic Spine in Trunk Rotation

Kinematics of the Thoracic Spine in Trunk Rotation

Dr. GJohn Mullen Biomechanics, Blog, Dr. John Mullen, Latest&Greatest, Training 2 Comments

Thoracic spine rotation is used in long-axis swimming. Therefore, understanding the biomechanical demand of this motion is mandatory to understand the optimal hydrodynamics. Unfortunately, the thoracic spine is rarely researched due to the low volume of injuries at this region. Simply comparing the thoracic spine to other areas is unjust, as the thoracic spine has many differences from the rest …
