To enhance understanding of how organizational responses shift, we use a longitudinal case study of the National Football League’s (NFL) responses to institutional change around the issue of player concussions.

Hamstring strain injury (HSI) is the most prevalent injury in football (soccer), representing 12% of all injuries in high-level players. 1 A professional team can expect 5 to 6 HSIs per season, 2 and these injuries typically have persistent symptoms 3 and high recurrence rates. 2 Players “off

Football performance depends on several aspects, such as technical, tactical, psychological, physical, and physiological factors. 1 From a physiological standpoint, football is a high-intensity intermittent exercise mode that combines short and intense bouts with other low-intensity movements, 2

The purpose of the current study was to empirically examine the potential course content, structure, and delivery mechanisms for a dedicated elite youth coach education programme in football (soccer) in the UK. By achieving this aim it was the intention of the authors to use the findings of this study for the future development of a customised coach education programme. Fifteen elite coaches, working in youth football at the time of the study, participated in one of three focus groups. Emerging from content analysis procedures, the findings placed specific importance on the development of an athlete-centred coaching philosophy, a focus on behaviours and activities associated with positive youth development, a movement away from traditional practices, and the development of the skills required to learn through reflective practice. In addition, a range of pedagogical approaches, including social approaches to learning, mentoring, and blended learning, were highlighted as ways to better deliver education programmes.

Alcohol consumption at college football games concerns stadium and university administrators because of the risk of alcohol-related crime, injury, and other potential problems. The purpose of this study was to determine how many of the 120 NCAA Division I Football Bowl Subdivision athletic department Web sites posted their stadium alcohol policies, what their alcohol policies contained, and how they differed. An analysis of information about the availability of alcohol, restrictions on alcohol consumption, and the enforcement of the policies on their official university-sponsored athletic department stadium Web sites was conducted. Results of the study suggested that alcohol policy information is often unavailable or difficult to locate. College athletic department Web sites are typically filled with varying information about their sport teams, but because of the layout and busy nature of such sites, it is often difficult to find certain information on them.

To compare a novel sprint test on a cycle ergometer with a countermovement-jump (CMJ) test for monitoring neuromuscular fatigue after Australian rules football match play.
Twelve elite under-18 Australian rules football players (mean ± SD age 17.5 ± 0.6 y, stature 184.7 ± 8.8 cm, body mass 75.3 ± 7.8 kg) from an Australian Football League club’s Academy program performed a short sprint test on a cycle ergometer along with a single CMJ test 1 h prematch and 1, 24, and 48 h postmatch. The cycle-ergometer sprint test involved a standardized warm-up, a maximal 6-s sprint, a 1-min active recovery, and a 2nd maximal 6-s sprint, with the highest power output of the 2 sprints recorded as peak power (PP).
There were small to moderate differences between postmatch changes in cycle-ergometer PP and CMJ PP at 1 (ES = 0.49), 24 (ES = –0.85), and 48 h postmatch (ES = 0.44). There was a substantial reduction in cycle-ergometer PP at 24 h postmatch (ES = –0.40) compared with 1 h prematch.
The cycle-ergometer sprint test described in this study offers a novel method of neuromuscular-fatigue monitoring in team-sport athletes and specifically quantifies the concentric component of the fatigue-induced decrement of force production in muscle, which may be overlooked by a CMJ test.
