The incidence of shoulder injuries in the paediatric athletic population continues to increase with increased participation particularly in throwing and overhead sports. While soft tissue injuries can occur, the physis remains the weak link and site of injury in many cases. Injury prevention targets proper throwing mechanics and the avoidance of overuse injuries by monitoring the amount of trai...

Optimum projection angles for achieving maximum horizontal range in throwing and jumping events are considerably less than 45°. This unexpected result arises because an athlete can generate a greater projection velocity at low projection angles than at high angles. The range of a projectile is strongly dependent on projection speed and so the optimum projection angle is biased towards low proje...

this study aimed at examining the effect of different focus of attention instructions and cognitive styles on the learning of dart throwing skill. 80 children were randomly selected and divided into four equal groups: a) field independent-external attention, b) field independent-internal attention, c) field dependent-external attention and d) field independent-internal attention based on their ...

With millions of athletes participating in baseball in the United States annually, overuse injuries are common occurrences. Epidemiological studies, including surveys of orthopaedic surgeons, coaches, and athletes, indicate that injuries such as those to the ulnar collateral ligament are increasing in incidence. Many risk factors for throwing injuries have been proposed-including the immature s...

Overhand throwing requires contributions from and interaction between all limb segments. Most previous investigations have concentrated on the throwing arm itself, yet poor mechanics at the arm may originate in the lower extremities. Multicomponent ground-reaction forces of both the push-off and landing limbs were measured in six collegiate and one high school level baseball pitchers. Full body...

The purpose of this study was to compare the differences in throwing performance and kinematics between throwing with the dominant and non-dominant arm in experienced handball players. Significant differences in throwing performance (accuracy and ball velocity) were found between the dominant and non-dominant arm. Maximal velocity of most joint movements was significantly different between the ...

Previous evidence suggests that augmented sensorimotor rhythm (SMR) activity is related to the superior regulation of processing cognitive-motor information in motor performance. However, no published studies have examined the relationship between SMR and performance in precision sports; thus, this study examined the relationship between SMR activity and the level of skilled performance in task...
