Researchers have argued that leadership is one of the most important determinants of team effectiveness. The present study examined the extent to which the perceived quality of athlete leadership was related to the effectiveness of elite sports teams. ⋯ High-quality athlete leadership is positively related to team effectiveness. Given the importance of high-quality athlete leadership, the study highlights the need for well-designed empirically-based leadership development programs.

Quantitative and non-invasive measurements acquired by neurocognitive or gait evaluations are useful concussion management components. Emerging technology has allowed for the development of portable and objective tests which may be potentially useful across many settings where evaluations take place. Our aim was to examine the association between instrumented dual-task gait and tablet-based neurocognitive outcome variables with an acute concussion. ⋯ Relatively simple quantitative measurements of dual-task gait and reaction time may be useful and portable clinical tests in the multifaceted assessment of concussion.

Non-disclosure of concussion complicates concussion management, but almost nothing is known about non-disclosure in military settings. This study describes concussion disclosure-related knowledge, attitudes, perceived social norms, perceived control, and intention. Additionally, the study identifies determinants of high intention to disclose concussion symptoms. ⋯ Concussion-related perceived social norms, attitudes, and perceived control are associated with intention to disclose. Organizationally appropriate intervention strategies can be developed from these data.

To investigate the influence of BMX helmets and neck braces on translational and rotational accelerations in youth riders. ⋯ Accelerations at the head decreased with increased age, possibly due to the influence of greater stabilising musculature. Additionally, neck braces also significantly reduced the number of accelerations. However, the magnitude of accelerations may be influenced by riding dynamics. Therefore, the use of neck braces combined with strength work to develop neck strength, could aid in the reduction of head accelerations in youth BMX riders.

To determine which variables predict prolonged (>28 days) duration of symptoms after a concussion. ⋯ Among adult patients with concussions, those with a higher symptom burden after injury have an increased odds of suffering from prolonged symptoms. Other potential predictor variables are not associated with the risk of prolonged recovery.
