Research ArticleOpen accessIn the abstractThe Upper Limit of Physiological Cardiac Hypertrophy in Elite Male AthletesMohammad Al Hnidawei, Majed MjallI, Ziad ZayedProblem statement: Establishment of upper normal limits of physiological hypertrophy in response to physical training is important in the differentiation of physiological and pathological left ventricular hypertrophy. The goal of our study was to investigate the normal upper limits of cardiac dimensions in elite athletes in Jordan in different types of sports (8 soccer players, 8 sprinters, 8 long distance … …American Journal of Applied Sciences, Vol. 7, Issue 10 · 31 Oct 2010 · 7,107 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effects of Fatigue and Chronic Ankle Instability on Dynamic Postural ControlSeyed Hossein Hosseinimehr, Hassan Daneshmandi, Ali Asghar NorastehProblem statement: The proprioception information is a prerequisite for balance, body's navigation system and the movement coordinator. The aim of this study was to investigate the effects of fatigue and chronic ankle instability on dynamic postural control. Approach: Thirty physical education students (14 males, 16 females) in two groups (15 healthy age = 21.78±0.79 years, height = 168.3±5.6 cm and … …Physics International, Vol. 1, Issue 1 · 31 Mar 2010 · 8,872 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Examination of Teaching Behaviors and Learning Activities in Physical Education Class Settings Taught by Three Different Levels of TeachersHoward Z. Zeng, Raymond W. Leung, Michael HipscherProblem statement: To be an accredited teacher education program, physical education teacher education (PETE) programs must fulfill the national standards established by the National Association for Sport and Physical Education (NASPE). In order to meet the standards, a PETE program needs to have the cooperation of the following three levels of instructors: Specialist Teachers (STs), Inservice Teachers (ITs) and Preservice … …Journal of Social Sciences, Vol. 6, Issue 1 · 31 Mar 2010 · 8,658 accessesView PDFCite
