Scapular Contribution for the End-Range of Shoulder Axial Rotation in Overhead Athletes
Throwing-shoulder overhead-athletes scapular internal and external rotation
2015/5/13
The aim of this study was to analyze the relative contribution of the scapular motion on the extreme range-of-motion of shoulder external and internal rotation, in overhead athletes. An electromagneti...
Muscle activity response to external moment during single-leg drop landing in young basketball players: The importance of biceps femoris in reducing internal rotation of knee during landing
ACL injury risk factors knee moment muscle activation.
2015/5/11
Internal tibial rotation with the knee close to full extension
combined with valgus collapse during drop landing generally
results in non-contact anterior cruciate ligament (ACL) injury.
Trunk Rotation and Weight Transfer Patterns between Skilled and Low Skilled Golfers
Golf kinematic kinetic skill level
2015/5/4
The purpose of this study was to examine trunk rotational patterns and weight transfer patterns that may differentiate swing skill level in golfers. Thirteen skilled golfers (mean handicap = 0.8 ± 2.6...
Glenohumeral Internal Rotation Deficit in the Asymptomatic Professional Pitcher and its Relationship to Humeral Retroversion
Glenohumeral internal rotation humeral retroversion pitcher ROM
2015/4/7
The purpose of this study was to determine if glenohumeral internal rotation deficits (GIRD) exist in an asymptomatic population of professional pitchers, and to assess whether these changes are prima...
Relationship Between Maximum Shoulder External Rotation Angle During Throwing and Physical Variables
Throwing shoulder elbow injury prevention
2015/4/7
The amount of stress imposed on shoulder and elbow appears to be directly correlated with the degree of maximum shoulder external rotation (MER) during throwing motions. Therefore, identifying risk fa...
Internal Rotation and Scapular Position Differences: A Comparison of Collegiate and High School Baseball Players
glenohumeral joint glenohumeral internal-rotation deficit scapular dyskinesis
2010/9/8
Conditions such as labral and rotator cuff injuries have been linked with decreases in glenohumeral internal-rotation and increases in external-rotation motion. Also, decreased glenohumeral internal r...
THE KINEMATIC MODEL OF THE BOUNCE-OFF PHASE IN SOME ACROBATIC ELEMENTS WITH FORWARD BODY ROTATION
push-off phase kinematic parameters handspring salto forward tucked to roll out
2009/8/26
The aim of this study was a comparison of the kinematic parameters important for defining a model technique of the push-off phase in performing acrobatic elements with forward body rotation, as well a...
Glenohumeral Rotation and Scapular Position Adaptations After a Single High School Female Sports Season
scapular dyskinesis posterior shoulder capsule
2010/9/9
Anterior instability and impingement are common in overhead athletes and have been associated with decreases in internal rotation (IR) and increases in external rotation (ER) motion. However, the chro...
The role of visual input during rotation: the case of discus throwing
Discus throwing Visual information Central vision Peripheral vision
2010/9/17
In order to investigate the contribution of visual information in the control of a skill involving rotation, ten experienced discus throwers performed throws under full vision, peripheral vision only,...
