AbstractObjectivesDetermine, through video reviews, how often concussions occur in combat sport matches, how well non-medical personnel can be trained to recognize concussions and how often fights are judged to continue too long.MethodsThis is a retrospective video analysis by an 8 person panel of 60 professional fights (30 boxing and 30 mixed martial arts). Through video review, medical and non-medical personnel recorded details about each probable concussion and determined if and when they would have stopped the fight compared to the official stoppage time.ResultsA concussion was recorded in 47/60 fights. The fighter that sustained the first concussion ultimately lost 98% of the time. The physician and non-physician raters had 86% agreement regarding the number of concussions that occurred to each fighter per match. The mean number of concussions per minute of fight time was 0.08 (0.06 for boxers and 0.10 for MMA). When stratifying by outcome of the bout, the mean number of concussion per minute for the winner was 0.01 compared to the loser at 0.15 concussions per minute. The physician raters judged that 24 of the 60 fights (11 boxing [37%]; 13 MMA [43 %]) should have been stopped sooner than what occurred.ConclusionRecognizing that the losing fighter almost always is concussed first and tends to sustain more concussions during the fight, along with the demonstration that non-physician personnel can be taught to recognize concussion, may guide policy changes that improve brain health in combat sports.

Strong classroom management may be the key to finding success as a new teacher. Yet many teachers seek additional professional development in managing classrooms that include students with disabilities. The purpose of this article is to provide new teachers and teacher educators with a prescriptive yet self-led approach to systematically improving classroom management practices using a sequential video analysis process. This article outlines an easy-to-follow four-step process that teachers can use to record, review, reflect on, and revise their instruction. A checklist of evidence-based classroom management strategies with video exemplar links, a free online observation tool called the Classroom Teaching Scan, and a guide for self-reflection called the Reflection Matrix are all explained. Through this highly structured yet self-led approach, teachers can independently engage in noticing elements of teaching, identify their own areas of strength and weakness, reflect in a meaningful way, and implement evidence-based classroom management practices.

Mathematics teacher educators (MTEs) designed and studied a video analysis activity intended to support prospective teachers (PSTs) in learning to notice equitable instructional practices. PSTs from 4 sites (N = 73) engaged in the activity 4 to 5 times during the semester, using a set of 4 “lenses” to analyze teaching and learning as shown in videos. In an earlier analysis of this activity, we found that PSTs increased their depth and expanded their foci in noticing equitable instructional practices (Roth McDuf_ e et al., 2013). In this analysis, we shift the focus to our work as MTEs: We examine our decisions and moves in facilitating the video analysis activity with a focus on equity, and we discuss implications for other MTEs.

Retrospective Video Analysis

Objective. To assess the drinking behaviours of top competitors during an Olympic marathon. Methods. Retrospective video analysis of the top four finishers in both the male and female 2004 Athens Olympic marathons plus the pre-race favourite in the female race in order to assess total time spent drinking. One male and female runner involved in a laboratory drinking simulation trial. Results. For the five female athletes, 37 of a possible 73 drinking episodes were captured. The female race winner was filmed at 11 of 15 drinking stations. Her total drinking time was 23.6 seconds; extrapolated over 15 seconds this would have increased to 32.2 seconds for a total of 27 sips of fluid during the race. Eighteen of a possible 60 drinking episodes for the top four male marathon finishers were filmed. The total drinking time for those 18 episodes was 11.4 seconds. A laboratory simulation found that a female athlete of approximately the same weight as the female Olympic winner might have been able to ingest a maximum of 810 ml (350 ml.h-1) from 27 sips whilst running at her best marathon pace whereas a male might have drunk a maximum of 720 ml (330 ml.h-1) from 9 sips under the same conditions. Conclusions. These data suggest that both the female and male 2004 Olympic Marathon winners drank minimal total amounts of fluid (<1 litre) in hot (>30ºC) temperatures while completing the marathon with race times within 2.5% of the Olympic record.
