RESUMO
Blood flow restriction (BFR) training is commonly used to induce muscle hypertrophy and strength and is gaining popularity as a modality for treatment of musculoskeletal conditions and postoperative rehabilitation. This article reviews the current literature on BFR as a rehabilitative tool, identifies gaps in the literature, and reports the authors experience using BFR in the postoperative environment.

Helping a wrestler manage body weight can be a daunting process for a pediatric health care provider. Each high school wrestling program has been mandated by the National Federation of State High School Associations to determine an appropriate weight classification for each individual wrestler. This article discusses how an appropriate weight class is determined, the methods for ascertaining a person's hydration status and body density, and the importance of a fully hydrated and normally nourished state that will allow for optimal athletic performance for a wrestler.

OBJECTIVE: To measure and analyze head accelerations during American collegiate football practices and games. METHODS: A newly developed in-helmet 6-accelerometer system that transmits data via radio frequency to a sideline receiver and laptop computer system was implemented. From the data transfer of these accelerometer traces, the sideline staff has real-time data including the head acceleration, the head injury criteria value, the severity index value, and the impact location. Data are presented for instrumented players for the entire 2003 football season, including practices and games. SETTING: American collegiate football. SUBJECTS: Thirty-eight players from Virginia Tech's varsity football team. MAIN OUTCOME MEASUREMENTS: Accelerations and pathomechanics of head impacts. RESULTS: : A total of 3312 impacts were recorded over 35 practices and 10 games for 38 players. The average peak head acceleration, Gadd Severity Index, and Head Injury Criteria were 32 g +/- 25 g, 36 g +/- 91 g, and 26 g +/- 64 g, respectively. One concussive event was observed with a peak acceleration of 81 g, a 267 Gadd Severity Index, and 200 Head Injury Criteria. Because the concussion was not reported until the day after of the event, a retrospective diagnosis based on his history and clinical evaluation suggested a mild concussion. CONCLUSIONS: The primary finding of this study is that the helmet-mounted accelerometer system proved effective at collecting thousands of head impact events and providing contemporaneous head impact parameters that can be integrated with existing clinical evaluation techniques.
