  • incidence of sudden cardiac arrest in High School Student athletes on School campus
    Heart Rhythm, 2014
    Co-Authors: Brett G Toresdahl, Ashwin L Rao, Kimberly G Harmon, Jonathan A Drezner
    Abstract:

    Background An accurate estimate of the incidence of sudden cardiac arrest (SCA) in High School Student athletes is needed to guide prevention strategies. Objective To prospectively investigate SCA rates in High School Student athletes vs Student nonathletes. Methods A prospective observational study of 2149 US High Schools participating in the National Registry for AED Use in Sports was conducted from August 2009 to July 2011. Schools were contacted quarterly to collect and review SCA cases occurring on School campus. Ninety-five percent (2045) of the Schools confirmed participation for the entire 2-year period. Results The average numbers of total Students and Student athletes per School were 963 and 367, respectively, providing more than 4.1 million total Student-years and more than 1.5 million Student athlete-years of surveillance. Twenty-six cases of SCA occurred in Students, including 18 cases in Student athletes—all during exercise. The incidence of SCA in all Students was 0.63 per 100,000; in Student athletes, 1.14 per 100,000; and in Student nonathletes, 0.31 per 100,000. The relative risk of SCA in Student athletes vs nonathletes was 3.65 (95% confidence interval 1.6–8.4; P P Conclusion The incidence of SCA in High School Student athletes is Higher than previous estimates and may justify more advanced cardiac screening and improved emergency planning in Schools.

    Journal of the American College of Cardiology, 2014
    Co-Authors: Jonathan A Drezner, Kimberly G Harmon, Joseph C Marek
    Abstract:

    To the Editor: An accurate understanding of the incidence of cardiovascular events in athletes is central to the development and evaluation of screening guidelines.

  • Numerical study on effect of thermal regulation performance of winter uniform on thermal responses of High School Student
    Building and Environment, 2018
    Co-Authors: Zhongxiang Lei, Yunyi Wang
    Abstract:

    Abstract The objective of the study was to numerically investigate the effect of thermal regulation performance provided by the winter School uniforms varying in wearing methods on thermal responses. A model of human thermal regulation was used to predict the human physiological responses while sedentary in an indoor environment and exercising in an outdoor environment, and further validated against measured data in human trials. TSENS and UCB comfort models were coupled to the thermal regulation model for predicting human thermal sensation. The predictions were then compared with the subjective responses to surveys. The results showed that the thermal regulation model coupled to UCB comfort model presented the potential for providing a means for reasonably accurate prediction of the thermal sensation in both indoor and outdoor environments. Based on the presented model, it was demonstrated that the difference of mean skin temperatures caused by the different wearing methods of School uniforms ranged from 1.26 to 1.99 °C. Thus, the designs on thermal regulation performance provided by the wearing methods of School uniform were extremely important for Students to improve their thermal comfort while switching between the indoor and outdoor environments.
