Comparison Of Two Training Programs On Acceleration Out Of The Break In American Football, Micah Adam Alba

Theses and Dissertations

Athletes of American football need the ability to stop, start, and reach top speed in an efficient manner. Football players on the defensive side of the ball require the skill of stopping a backward run and accelerating to a forward run. This action is termed the break. Football players receive year-round training in an effort to improve performance. Yet, many times, these athletes may not focus specifically on the muscular systems that are unique to the position they play. The law of specificity states that the more specific the training is for the action required, the more beneficial the outcome. …

Physical Education Content Knowledge And Physical Activity Behaviors Of Mississippi High School Students, Christina Leigh Lumpkin Martin

Dissertations

The present study investigated physical education content knowledge, physical activity behaviors, and body mass indexes of 386 Mississippi ninth (n=236 ) and twelfth (n=150) grade students with a goal of establishing evidence-based needs to modify physical education curricula. Results of this study suggested that a significant, direct relationship did exist in the Assessment of Sub-disciplinary Knowledge in Physical Education: Exercise Physiology (ASK PE: EXP);(Ayers, 2004) scores and scores from the Modifiable Activity Questionnaire for Adolescents (M4<2^4);(Aaron & Kriska, 1997) for both ninth and twelfth grade students. Findings also suggested that physical education content knowledge (exercise physiology) is more likely to contribute to twelfth grade reported physical activity scores than ninth grade reported physical activity scores. However, ninth graders were more active than twelfth graders. This is possibly explained by the small difference (5%) in ASK PE: EXP scores between ninth (M ASK PE: EXP score = 52%, SD=.22) and twelfth graders (M ASKPE: EXP score = 57%, SD = .21). As a whole, results indicated that Mississippi ninth and twelfth grade students' average ASKPE: EXP score was lower (M = 53%, SD = .22) than students in 16 other states (M = 62%, SD = 7.65). Further, majority of Mississippi high school students are performing significantly below the established, research-based cutoff score of 62% (observed N below 62% = 236 and observed N above 62% = 150). This is notable, because findings also suggested that students who scored higher (M knowledge = 76%, SD = .08);(M activity = 8.6 hours/week, SD = 9.7) or above 62% on the ASK PE: EXP were more likely to be active during a weekly basis compared to those who scored lower (M knowledge = 39%, SD = .14);(M activity = 5.8 hours/week, SD = 9.8) or below a 62% on the ASK PE: EXP. With this noted, it was recommended that Mississippi high schools evaluate the current physical education programs, and strive to implement curricula that can provide students with the necessary knowledge and skills to make lifelong healthy decisions.
