OBJECTIVE: Throwing is a dynamic and complex task, which requires sequential movement to sufficiently transfer energy from the lower extremity to the upper extremity. Due to the repetitive stress of the overhead throwing motion, sport medicine personnel have developed different methods to assist in alleviating pain an athlete may be experiencing. One method is the use of a posture-cueing compre...

It is a commonly held perception amongst biomechanists, sports medicine practitioners, baseball coaches and players, that an individual baseball player's style of throwing or pitching influences their performance and susceptibility to injury. With the results of a series of focus groups with baseball managers and pitching coaches in mind, the available scientific literature was reviewed regardi...

Sport-specific upper extremity strain, mostly unilateral, during growth may lead to adaptations in soft tissue and bone. We investigated 51 male professional handball players between 18 and 39 years of age (average, 27 years), 39 right-handed and 12 left-handed. Thirty-eight players had no shoulder problems, and 13 had chronic shoulder pain. Humeral retrotorsion was determined by radiograph. Th...

For medical or sports applications, human motor control is frequently analyzed. In this study, we focus on dart throwing motion and investigate the human motor skill to achieve precision control and force generation. The joint coordination is related to stability and accuracy of movements for precision control. On the other hand, the joint correlation is related to transfer of forces and moveme...

[Purpose] The physical strength elements required for athletic throwing events include muscle strength, swiftness, agility, speed, flexibility, and physical balance. Although plyometric training and weight training are implemented as representative training methods for improving swiftness and agility, most studies of it have been conducted with players of other sports. [Subjects] The study subj...

In team-handball competition, the players utilize various throwing techniques that differ in the lower body movements (with and without run-up or jump). These different lower body movements influence changes in the upper body movements and thus also affect the performance. A comprehensive analysis of 3D-kinematics of team-handball throws that may explain these differences in performance is lack...

Submitted January 10, 2015; revision received February 15, 2015; accepted February 24, 2015. “Little league shoulder” is caused by repeated overhead throwing in athletes between the ages of 11 and 14 years during peak proximal physis growth.1,2 The rotational torque during maximum external rotation when throwing overhead seems to be the primary cause of growth plate failure.1-3 (doi:10.7556/jao...

In combat sports, the specificity of training requires that athlete improve all performance indicators associated with match. For this reason, muscle power seems to be determinant during application techniques result in scores, specifically punches, kicks, elbows, knees, throwing techniques, transitions groundwork and some sometimes, win match by knockout. Based these information’s, present cha...

Many investigators have demonstrated that in swing motions such as ball-throwing, the motion of the proximal joint (shoulder) produced assistive interaction torque for the distal joint (elbow). In line with these studies, the shoulder and elbow motions would be expected to produce the assistive interaction torque for the wrist joint as well. However, we recently showed that the interaction torq...
