Overhead throwing motion imparts enormous forces on the elbow. Repetitive near-failure loads lead to chronic adaptive changes and occasionally acute injury to bone, ligaments, and the elbow's muscle-tendon complexes. Physicians treating the thrower must thoroughly understand the complex anatomy and function of the elbow joint and throwing biomechanics to diagnose and treat elbow pathology. Eval...

The purpose of this study was to investigate some characteristics of aspiration levels of Type A preschoolers. Twenty-two Type A and twenty-one Type B subjects selected from 245 preschoolers were given three tasks: ball-throwing task 1, ball-throwing task 2, and ringtoss task. After investigating some basic characteristics of aspiration levels in a standard situation (ball-throwing task 1), ris...

Abstract This paper establishes a mathematical model of basketball sports based on an ADDIE model. takes players’ pitching as the research object. Then use method to analyze best angle goal improve accuracy throwing. Firstly, this dynamic movement and then shows equation trajectory. uses optimize solve basketball. At same time, proposes motion control rotation using adaptive trajectory correcti...

The execution variability and outcomes found in throwing actions have received special attention in numerous studies in recent years. The aim of this study was to analyze the effect of an unstable condition on velocity, accuracy and kinematics of movement in the seven metres throw in handball. Twenty-five young handball players took part in an experiment, throwing towards a target on a stable a...

In this study we investigate the effect of modeling type and reflection on the acquisition of dart-throwing skills, selfefficacy beliefs and self-reaction scores by replicating a study by Kitsantas, Zimmerman, and Cleary (2000). Participants observing a coping model were expected to surpass participants observing a mastery model who in turn were expected to outperform participants who learned w...

Seed Throwing Optimization is an easy to implement probabilistic metaheuristic for multimodal function optimization with roots in hill climbing and the evolutionary computation like technique Harmony Search. It is a randomized Gradient Ascent with multiple initial states and the possibility to limit exploration to only paths which have shown potential. In this paper, the speed of convergence of...

Treatment of the overhead throwing athlete is among the more challenging aspects of orthopaedic sports medicine. Awareness and understanding of the throwing motion and the supraphysiologic forces to which the structures of the shoulder are subjected are essential to diagnosis and treatment. Pain and dysfunction in the throwing shoulder may be attributed to numerous etiologies, including scapula...
