Comparative Study
Leading together towards a stronger 'us': An experimental test of the effectiveness of the 5R Shared Leadership Program (5RS) in basketball teams.
Leadership has been suggested to be a key factor in gaining a competitive advantage as a team, with shared leadership being a better predictor of team functioning than vertical leadership. Although the benefits of shared leadership are well-documented, evidence about how to implement a shared leadership structure remains sparse. This leaves coaches with three key challenges: (1) identifying the best leaders; (2) defining what roles those leaders should fulfill; and (3) developing their leadership skills. Solutions to these challenges have been proposed in the 5R Shared Leadership Program (5RS) - a leadership development program that seeks to implement an effective structure of shared leadership within sports teams. ⋯ The present study provides encouraging evidence that, by implementing a structure of shared leadership and by promoting athlete leaders' identity leadership skills, the 5RS program is able to improve the team's functioning and the well-being of its members.

To determine whether pain perceptions and coping strategies are predictive of the following outcomes after knee surgery in athletes: (1) return to similar level of sport, (2) improvement in symptoms, and (3) improvement in kinesiophobia. ⋯ Among athletes undergoing knee surgery, severe pain catastrophizing is negatively associated with return to similar level of sport. Instrumental support and problem-focused coping strategies are associated with improved outcomes. High preoperative pain scores are negatively associated with improvement in kinesiophobia after rehabilitation.

To assess the effect of mid-flight trunk flexion and extension on the movements of body segments and lower extremity joints and subsequent landing mechanics during a jump-landing task. ⋯ Mid-flight trunk extension resulted in body postures that predisposed individuals to land with increased knee extension and varus moments and decreased knee flexion angles, which are indirectly associated with increased ACL loading. These findings may help to understand altered trunk motion during certain ACL injury events and provide information for developing jump-landing training strategies.

To prospectively evaluate single/dual-task timed-up-and-go (TUG) and tandem gait performance among children and adolescents with concussion and healthy controls. ⋯ Slower dual-task TUG and tandem gait times were detected across both time points for the concussion group relative to the control group. In contrast, single-task tandem gait deficits appeared to improve in a similar fashion as symptoms, suggesting increased complexity from the addition of a cognitive task allows for the detection of persistent post-concussion deficits that might take longer to resolve.

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.
