Recognized side effects on health associated with sports participation in youth include overtraining, doping, and exposure to harassment and violence. Many of these effects originate in contexts where young athletes are beginning to make decisions about their sports practices on their own. This study set out to explore knowledge and reasoning about health among adolescent athletes and to describe how health knowledge management structures are associated with different social systems. Qualitative data were collected from focus groups involving 65 young Swedish athletes aged 16 to 17 years...

Importance: Approximately one-third of children who experience a concussion develop prolonged concussion symptoms. To our knowledge, there are currently no objective or easily administered tests for predicting prolonged concussion symptoms. Several studies have identified alterations in epigenetic molecules known as microRNAs (miRNAs) following traumatic brain injury. No studies have examined whether miRNA expression can detect prolonged concussion symptoms. Objective: To evaluate the efficacy of salivary miRNAs for identifying children with concussion who are at risk for prolonged symptoms...

In all countries life expectancy is rising, and many older persons spend a longer period in good health. Nevertheless, frailty is present in older people and can be considered as a risk factor for limitations. The "German Health Interview and Examination Survey for Adults" (DEGS1) 2008 - 2011 comprised interviews, examinations and tests. Data on 1110 community-dwelling people aged 70 to 79 years participating in DEGS1 with full records on frailty were analysed. Physical frailty was defined as exhaustion (SF-36 item), low grip strength, slowness (Timed Up-and-Go test > 15 seconds or unable to perform) and low physical activity (no sports or exertion)...

This study examines young volleyball players' learning of increasingly complex attack gestures. The main purpose of the study was to examine the predictive role of a cognitive variable, working memory capacity (or "M capacity"), in the acquisition and development of motor skills in a structured sport. Pascual-Leone's theory of constructive operators (TCO) was used as a framework; it defines working memory capacity as the maximum number of schemes that can be simultaneously activated by attentional resources...

Repetitive stress fracture of the middle phalanx epiphysis is an injury specific to elite adolescent sport climbers. As sport climbing becomes increasingly popular in younger age groups, an increased number of these injuries have been reported in recent years. To date, treatment of these fractures has been nonsurgical, with strict rest and physiotherapy prescribed until fracture union. However, when these patients present in a delayed fashion with an established nonunion, nonsurgical treatment may fail, leading to disabling chronic pain and/or digital deformity in some cases...
