Stress fractures have been reported in the upper limb of sportspeople involved in upper limb dominated events. Olecranon stress fractures have been cited in baseball pitchers, javelin throwers, and gymnasts. The unusual case of a stress fracture of the olecranon in a young weight lifter is reported here. The minimally displaced stress fracture was treated with tension band and two Kirschner wir...

The purpose of this study was to use regularised regression models identify the most important biomechanical predictors throwing distance in elite male (M) and female (F) javelin throwers at 2017 IAAF world championships. Biomechanical data from 13 12 who competed championships were obtained an official scientific report. Regularised used investigate associations between release parameters, who...

Aim of the present study was to describe the muscle fibre type composition and body composition of well-trained hammer throwers. Six experienced hammer throwers underwent the following measurements: one repetition maximum in squat, snatch, and clean, standing broad jump, backward overhead shot throw and the hammer throw. Dual x-ray absorptiometry was used for body composition analysis. Fibre ty...

0.4 1.0 0.8 Although the mean values indicate the younger British squad to be slightly taller, lighter and fatter, their ranges, in fact, span the mean American values for each parameter. The throwers, with a mean 16.0% body fat, are the same order of fatness as non-athletic males, reported by Fox and Mathews (1981) to be 16.8%, although Parizkova (1977) found a mean value of 12% for the 20-30 ...

The purpose of this study was to investigate the differences between weightlifters and track field throwers in terms rate force development (RFD), lean mass, muscle architecture one-repetition maximum (1-RM) strength. Sixteen elite male athletes (eight eight throwers) participated study. Measurements were performed one week after annual national championships included anthropometry, body compos...

BACKGROUND Spontaneous fracture of the humeral shaft in throwers is a rare but well-known phenomenon. Although it has been hypothesized that the biomechanics of the throw cause such fractures, it is not clear how or when the fractures occur in the pitching motion. METHODS The torque acting about the long axis of the humerus was calculated in 25 professional baseball pitchers throwing in game ...

Shoulder problems are common in throwing sports. Although there is still much to learn, knowledge of sequential muscle activation about the shoulder is expanding. Further elucidation of muscle activity involved in pitching a ball permits more specific conditioning to help improve performance, reduce injury, and assist rehabilitation in the event of injury. The aim of this study is to compare th...

Various mechanical forces produce a variable stimulus intensity on bone and have different effects on its growth and development. The aim of this project was to study the effects of a variety of mechanical forces on human humerus morphology. This was investigated by measuring the cortical thickness (cm) and diameter (cm) of the humerus at its proximal, middle and distal thirds from radiographs....

The primary aim of the present study was to prepare a set exercises on multi-resistor VertiMax device and identify effect these development endurance discus throwers under 16 years old. design experimental. Participants were selected using purposive sampling method. A total 5 discuss players constituted sample study. authors found significant improvement in levels performance as result training...

The aim of this study was to compare the plantar pressures and forces recorded from both feet of two groups of javelin throwers of different performance levels, in order to investigate differences between skill levels. The study was carried out using an EMED insole system on a Tartan javelin runway at the University of Innsbruck, Austria. Most of the differences (at p < .01) between the two gro...
