The teaching and learning of games and sport-based activities has historically been the dominant form of the physical education curricula. With an interest in providing to students meaningful and culturally situated sporting experiences, Sport Education is probably the most implemented and researched pedagogical model worldwide. However, although there is considerable evidence that the model as a curriculum approach can benefit the development of social goals and healthy sport behaviors, not a single study as to date examined students' game-play development beyond participation in single and isolated teaching units...

The aim of this study was to compare physical performance in amateur handball players of two different competitive levels. Thirty-four senior handball players were divided into two groups according to their competitive level (regional category: REG or national category: NAC). Although no significant differences were found between groups in any of the horizontal (HJ) or vertical jump (VJ) variables (p>0.05), NAC players obtained a better performance in the repeated sprint ability (RSA) test (RSABest [the best attempt] and RSATT [the total time in the total of sprints] in 15 m and 30 m), in change of direction ability (CODA) and in the Yo-Yo Intermittent Recovery test Level 1 (YYIR1) test (p<0...

Background: Reduced lower extremity muscle strength as well as reduced lower extremity muscle pre-activity (defined as muscular activity just prior to initial ground contact) during high-risk movements are factors related to increased risk of non-contact ACL injury in adolescent female athletes. A strong relationship exists between muscle strength and muscle activity obtained during an isometric contraction, however, whether these two measures are related when muscle activity is obtained during a movement associated with a high risk of non-contact ACL injury is not known...

Complete rupture of the scapholunate (SL) ligament can cause a dissociative carpal instability (CID). These ligamentous lesions are caused by a fall from a limited height of approximately 1 m or a fall, e. g. when playing handball or soccer. For a freshly injured wrist joint, the X‑ray signs of a static instability (after excluding a fracture) are a SL distance ≥3 mm, a SL angle >60°, and a dorsal displacement of the proximal scaphoid pole. Dynamic instabilities are best seen in kinematography of the wrist joint...

BACKGROUND: Anatomic findings on MRI scans of the shoulder likely affect patients differently based on their physical demands and fitness levels. The natural history of these anatomic findings once professional overhead athletes retire remains unclear. A better understanding of what happens with these findings after retirement may influence how we manage shoulder problems in athletes. PURPOSE: (1) What is the natural history of MRI-observed findings in the throwing and nonthrowing shoulders of professional European handball players after retirement from the sport? What proportion of these individuals have diagnosable findings on MRI, and do these findings disappear after retirement? (2) Do clinical findings such as Constant and Murley score and shoulder ROM change after retirement in these professional overhead athletes? METHODS: The inception cohort of this series consisted of the entire Swiss National European handball team except the goalkeepers...
