Tim Buszard, Rich S W Masters
A culture of striving was notable in the developmental background of many of the elite and super elite athletes in the Hardy et al. STUDY: Critically, a culture of striving was credited with a positive influence on a range of issues relevant to elite sports performance, including performance under pressure. Of the six athletes who did not reveal a culture of striving, five reported the greatest difficulty performing in high-pressure situations. We suspect that a culture of striving facilitates the development of attention control ability, which subsequently assists performance under pressure...

A foodborne illness outbreak involving an elite sports team was investigated by a public health unit in Sydney, Australia. An epidemiological association was established between gastrointestinal illness and the consumption of food supplied by an external caterer, with a lamb meal most strongly associated with illness. Genetically identical Salmonella isolates were identified from clinical specimens, residual food items, and an environmental swab taken from the catering premises. The training schedule and other club operations were significantly affected by this outbreak...

Ligament sprains, defined as tearing of bands of fibrous tissues within ligaments, account for a majority of injuries to the foot and ankle complex in field-based sports. External rotation of the foot is considered the primary injury mechanism of syndesmotic ankle sprains with concomitant flexion and inversion/eversion associated with particular patterns of ligament trauma. However, the influence of the magnitude and direction of loading vectors to the ankle on the in situ stress state of the ligaments has not been quantified in the literature...

OBJECTIVE: Stress fractures of the proximal epiphysis of the fifth metatarsal bone (termed Jones fracture) frequently occur in both senior high-school-age and older contestant-level soccer players, and its incidence in Japanese soccer players is higher than that in European players. Surgery is most commonly indicated for a complete fracture, and about 3 months are required before the patient is able to return to the sport. We have performed a "Jones fracture screening" to reduce the incidence of these fractures...

The relative age effect (RAE) describes an overrepresentation of players born early (Q1) in a selection year and is highly prevalent within youth sport pathways. However, a dearth of research has investigated the RAE at the "super-elite" level. The present research assessed the presence of RAE in super-elite performers. Study 1 investigated RAEs in the world's best international Test cricketers (N = 262) over a 20-year period according to a robust and stringent "super-elite" criteria. Results revealed the RAE (Q1) when all disciplines were combined...

Creatine is one of the most popular nutritional ergogenic aids for athletes. Studies have consistently shown that creatine supplementation increases intramuscular creatine concentrations which may help explain the observed improvements in high intensity exercise performance leading to greater training adaptations. In addition to athletic and exercise improvement, research has shown that creatine supplementation may enhance post-exercise recovery, injury prevention, thermoregulation, rehabilitation, and concussion and/or spinal cord neuroprotection...

CONTEXT: Proprioception is the basic element of the spontaneous control of movement, balance and joint stability. Therefore, it is necessary for the execution of walking and daily and sport activities. Loss of proprioception of the knee, which may cause a new injury, is important to evaluate the position sense of the joint during the rehabilitation period. However, the evaluation methods that are used are very expensive, complicated and non-portable, or the measuring method is difficult to implement...
