Pilot study to explore girls' lacrosse players' attitudes toward headgear.

Headgear adoption is a controversial issue in girls' lacrosse due to concerns that headgear use will facilitate greater risk-taking by players and contribute to more aggressive game play behaviours. The purpose of this pilot study was to evaluate high school girls' lacrosse players' attitudes towards headgear before and after a season of use. Twenty-five high school girls' lacrosse athletes wore headgear for one competitive season and completed a pre- and post-season survey.

Implementation of a pooled surveillance testing program for asymptomatic SARS-CoV-2 infections in K-12 schools and universities.

Background: The negative impact of continued school closures during the height of the COVID-19 pandemic warrants the establishment of cost-effective strategies for surveillance and screening to safely reopen and monitor for potential in-school transmission. Here, we present a novel approach to increase the availability of repetitive and routine COVID-19 testing that may ultimately reduce the overall viral burden in the community.

Methods: We implemented a testing program using the SalivaClear࣪ pooled surveillance method that included students, faculty and staff from K-12 schools (student age range 5-18 years) and universities (student age range >18 years) across the country (Mirimus Clinical Labs, Brooklyn, NY).

Lack of blood pressure difference by race in professional American football players.

Previous findings suggest that professional American football players have higher blood pressures (BP) and a higher prevalence of pre-hypertension and hypertension than the general population. We sought to determine whether race is associated with differences in BP and prevalence of pre-hypertension and hypertension among a large sample of professional football players. BP was measured at 2009 team mini-camps for 1484 black (n = 1007) and white (n = 477) players from 27 National Football League (NFL) teams.

Association of body mass index and waist circumference with subclinical atherosclerosis in retired NFL players.

Objectives: It is unknown which measure of adiposity (body mass index [BMI] or waist circumference [WC]) is associated with subclinical atherosclerosis in retired National Football League (NFL) players and whether this relation is attenuated after adjusting for components of the metabolic syndrome (elevated triglycerides, fasting glucose, and low levels of high-density lipoprotein-cholesterol [HDL-C]) that frequently coexist with obesity.

Methods: Coronary artery calcium (CAC) was measured in 926 retired NFL players. BMI was calculated as weight (in kilograms)/height (in meters)(2) and WC was measured in inches.
