This study was designed to assess the effect of strength and power training on throwing velocity and muscle strength in handball players according to their playing positions. Twenty-two male handball players were assigned to either an experimental group (n=11) or a control group (n=11) (age: 22.1 ± 3.0 years). They were asked to complete (i) the ball throwing velocity test and (ii) the one-repe...

case presentation this case concerns a 3-year-old girl whose medical history includes an acid attack suffered 3 years ago. she began treatment for the restoration of her scalp hair, but five weeks later, she presented at our clinic with a high-grade fever and infectious discharge from the commissure of the skull following a scalp expansion graft. microbiologic and radiologic work-ups were condu...

Motor skill is one of the most basic intelligent activities by human beings. We can acquire various high level physical skills such as throwing, typewriting, playing musical instruments and so on. However, it is di cult to understand the mechanism of the skill by experts. Here, we discuss motor skill in terms of dynamic constraint satisfaction including motion integrity constraint (MIC). Some b...

Chemokines play a key role in directing and driving leucocyte trafficking. The efficient regulation of leucocyte recruitment by chemokines requires their appropriate localization in functional micro-anatomical domains, as well as setting limits to their effects in space and time. Both processes are influenced by silent chemokine receptors (interceptors), including DARC (Duffy antigen receptor f...

This study aims to reveal the function of fingers during fastball (FB) and curveball (CB) pitches of a male adult who had played university baseball pitcher by conducting kinetic analysis on throwing motion with a link-segment model including finger segment. There was no apparent difference in the timing of peak finger joint angle between FB and CB pitches. Peak finger adduction torque in CB pi...

Study Design: Case control group study. Objectives: To compare scapular position and orientation between baseball players with and without pathologic internal impingement. Background: Scapular dysfunction has been implicated as a contributor to throwing-related pathologic internal impingement of the shoulder due to its role in increasing the contact between the greater tuberosity and posterior-...

The throwing athlete is at increased risk for injury to the shoulder because of the large and repetitive forces generated during the throwing motion. Injuries may occur from a single supraphysiologic load or from repeated subthreshold loads that cumulatively damage the tissue. The act of throwing has been classified, with some variation, into five stages: windup, early cocking, late cocking, ac...
