Evaluation of Implementation of Massachusetts Sports Concussion Regulations: Results of Focus Groups With School Nurses and Athletic Trainers.

In 2015, the Massachusetts Department of Public Health conducted focus groups with school nurses (SNs) and athletic trainers (ATs) from Massachusetts middle and high schools to assess implementation of legislated regulations relative to the management of students' head injuries incurred during extracurricular sports. Four tape-recorded focus groups were conducted by experienced facilitators. Lists of themes were synthesized by investigators for each focus group.

Comparison of two different resistance training intensities on excess post-exercise oxygen consumption in African American women who are overweight.

The purpose of this study was to compare a low- and high-intensity resistance exercise session of equal work on excess post-exercise oxygen consumption (EPOC). Ten African American (AA) overweight women performed a no-exercise control (CN) session, 3 sets of 9 resistance training exercises, for 15 repetitions (reps) at 45% of their 8-repetition maximum (RM) during 1 session (LO) and for 8 reps at 85% of their 8-RM during another session (HI). For each session heart rate (HR), ventilation volume (VE), oxygen consumption (VO₂), and respiratory exchange ratio, were collected continuously from 15 minutes pre exercise until 30 minutes post exercise.

Folding and organization of a contiguous chromosome region according to the gene distribution pattern in primary genomic sequence.

Specific mammalian genes functionally and dynamically associate together within the nucleus. Yet, how an array of many genes along the chromosome sequence can be spatially organized and folded together is unknown. We investigated the 3D structure of a well-annotated, highly conserved 4.

Effects of resistance exercise bouts of different intensities but equal work on EPOC.

Purpose: To compare the effect of low- and high-intensity resistance exercise of equal work output, on exercise and excess postexercise oxygen consumption (EPOC).

Methods: Fourteen female subjects performed a no-exercise baseline control (CN), and nine exercises for two sets of 15 repetitions at 45% of their 8-RM during one session (LO) and two sets of 8 repetitions at 85% of their 8-RM during another session (HI). Measures for all three sessions included: heart rate (HR) and blood lactate (La) preexercise, immediately postexercise and 20 min, 60 min, and 120 min postexercise; and ventilation volume (VE), oxygen consumption (VO(2)), and respiratory exchange ratio (RER) during exercise and at intervals 0-20 min, 45-60 min, and 105-120 min postexercise.
