The sports academia programs make it easier for these student athletes to focus on training for their sport while attending high school, and thereby, enable them to get a good education and enhance their athletic potential. These programs also have the potential to reduce drop-out in sports because it is easier for the students to balance athletics and academics. Nevertheless, sports performance is not necessarily linked to …

Body Composition, Physical Activity And Fitness In Children With Moderate-To-Severe Intellectual Disability, Sigurbjorn A. Arngrimsson, Ingi T. Einarsson

International Journal of Exercise Science: Conference Proceedings

Introduction: The prevalence of overweight and obesity has been rising in most parts of the world over the past two decades (1, 2). This rise could pose even a greater problem for people with intellectual disability (ID) because they are more likely to be obese than people without ID (3). Furthermore, research has shown that a sedentary lifestyle is more prevalent among people with ID than otherwise healthy people in modern society (4). In the general population, the adverse effects of obesity on health begin early in life and physical inactivity and adiposity are associated with metabolic diseases and cancers …

Comparison Of Two Back-Squat Training Protocols, Thomas A. Feild, Joe Priest Dr., Rod Cole

International Journal of Exercise Science: Conference Proceedings

Introduction. Eccentric Overload Training (EOT) and Conventional Training (CT) both contain eccentric components, however EOT utilizes more weight on the bar than the lifter can use during concentric contractions. Previous studies have suggested that EOT may produce benefits beyond what is observed for CT. Therefore, the purpose of this study was to compare the results of two different methods of strength training on one-repetition maximum (1-RM) back-squat (BkSq) and Hang Clean (HCl). Methods and Procedures. Ten collegiate male cheerleader athletes volunteered to participate in the study and performed 1-RM max back-squat prior to and following 13 weeks of training. Four …

Speed And Agility Prediction Models In High School Football Players, James J. Tufano, William E. Amonette, A. Eugene Coleman, Terry L. Dupler, Troy Wenzel

International Journal of Exercise Science: Conference Proceedings

Background: Optimal relationships between speed, agility, power and body mass are essential in American football. An increase in body mass, theoretically, reduces acceleration (Newton’s 2nd Law). However, an increase in lean body mass may enhance overall force or power generating potential and momentum of an athlete. Body mass, height, and vertical jump height are routinely measured, easily obtainable, and may be used as predictors of speed and agility. Purpose: To determine associations between height, vertical jump height, and body mass to speed and agility in high school football players. Methods: Data were collected on 1261 male football players (16.4±0.9yrs, 179.7±6.9cm, …
