BACKGROUND The Advanced Throwers Ten Exercise Program incorporates sustained isometric contractions in conjunction with dynamic shoulder movements. It has been suggested that incorporating isometric holds may facilitate greater increases in muscular strength and endurance. However, no objective evidence currently exists to support this claim. HYPOTHESIS/PURPOSE The purpose of this research wa...

[Purpose] For maximum efficiency and to prevent injury during javelin throwing, it is critical to maintain muscle balance and coordination of the rotator cuff and the glenohumeral joint. In this study, we investigated the change in the rotator cuff muscle strength, throw distance and technique of javelin throwers after they had performed a specific physical training that combined elements of we...

In the javelin throw training, many throwers improve their throwing technique by from a slower run-up velocity than in competitions. However, whether acquisition of is same as full unclear. The purpose this study was to clarify differences contribution each movement caused changes within an individual. Twelve collegiate male were included study. Throwers performed two types throws: one-cross (C...

The purpose of this study was to determine the kinematic factors related forward and vertical release velocities in male javelin throwers. movements 115 throwers who participated real competitions were videotaped by two cameras, coordinate values obtained using three-dimensional motion analysis technique. time-series changes data calculated, relationship with velocity directions confirmed calcu...

A Biomechanical analysis of Javelin Throw in the Sevilla’99 World Athletics Championships , was carried out by the University of Valencia (Department of Physical Education and Sports). This paper presents the results of a study of the male finalists. The methodology used is based on 3D Video Photogrammetry at 50 Hz. The results show the characteristics of the throwers’ individual model at the e...

Skilled throwers achieve accuracy in overarm throwing by releasing the ball on the handpath with a timing precision as low as 1 ms. It is generally believed that this remarkable ability results from a precisely timed command from the brain that opens the fingers. Alternatively, precise timing of ball release could result from a backforce from the ball that pushes the fingers open. The objective...

The practice of enhancing athletic performance through the use of ergogenic aids or by extraneous artificial means is as old as competitive sport itself. Although the abuse of such substances has been historically problematic, very little research assessing the attitudes of strength/power athletes concerning ergogenic aids exists. As national anti-doping organizations (NADOs) adopt preventative...

Many scientists agree that expertise requires both innate talent and proper training. Nevertheless, the highly influential deliberate practice model (DPM) of expertise holds that talent does not exist or makes a negligible contribution to performance. It predicts that initial performance will be unrelated to achieving expertise and that 10 years of deliberate practice is necessary. We tested th...

Tears of the rotator cuff, both partial, and less commonly, full thickness, are relatively common in the throwing athlete. The rotator cuff is subjected to enormous stresses during repetitive overhead activity. The supraphysiological strains, especially when combined with pathology elsewhere in the kinetic chain, can lead to compromise of the cuff fabric, most commonly on the undersurface where...

Background Ultrasonographic abnormalities of the patellar tendon frequently occur in asymptomatic athletes and it is not always clear whether they precede (and may predict) the development of tendinopathy. Objective This study aimed to investigate by ultrasonography the prevalence of patellar tendon abnormalities in players of "pallapugno" and to establish whether structural tendon abnormalit...
