INTRODUCTION: Posterior circumflex humeral artery (PCHA) aneurysm formation and thrombosis as overuse injury in the dominant shoulder can result in ischemia of the forearm, hand and digits due to arterial embolisms. Increased awareness among physicians is necessary as PCHA pathology (PCHAP) might be underdiagnosed. Knowledge of sports and professions at risk and risk-factors for obtaining PCHAP is essential for the development of future preventive measures. This study aims to identify sports and professions at risk as well as risk factors for PCHAP...

Background: Cognitive training (CT) aims to develop a range of skills, like attention and decision-making, through targeted training of core cognitive functions. While CT can target context specific skills, like movement anticipation, much CT is domain general, focusing on core abilities (e.g., selective attention) for transfer to a range of real-world tasks, such as spotting opponents. Commercial CT (CCT) devices are highly appealing for athletes and coaches due to their ease of use and eye-catching marketing claims...

BACKGROUND: The specificity of postural balance control in sports as gymnastic where complex motor skills are involved is widely debated in literature. The aim of this study was to investigate in young gymnasts whether the amount of training influenced postural balance control in a simple-task and in a sport-specific task. METHODS: Seven female Basic-Level Gymnasts (BLG) and eight female Advanced-Level Gymnasts (ALG) performed two tests on a dynamometric platform: bipedal standing (B) and single leg back scale (BS) before and after a combination of two gymnastic elements (rondade + flic-flac)...

The classical work by Robert C. Hickson showed in 1980 that the addition of a resistance training protocol to a predominantly aerobic program could lead to impaired leg strength adaptations in comparison to a resistance-only training regimen. This interference phenomenon was later highlighted in many reports, including a meta-analysis. However, it seems that the interference effect has not been consistently reported, probably because of the complex interactions between training variables and methodological issues...
