Book excerpt: ABSTRACT: The purpose of the current study was to investigate the differences in strength and power between playing positions and starters versus non-starters. Division III post-season male American football players (N = 38) participated in a descriptive study that consisted of strength, power, and dynamic performance variable testing. Subjects were grouped depending on playing position (skill, big skill, or line) and into starters and non-starters. Subjects completed a 3-repetition maximum hexagonal barbell deadlift to determine strength capabilities. Power output was assessed using a hexagonal barbell jump at 30, 40, 50, 60, and 70% of estimated 1RM. Dynamic performance variables consisted of depth jumps, to calculated ground contact time, jump height and reactive strength index, and 5, 10, 30m sprint capability. A statistically significant (p

Download or read book The Science of American Football written by Jay R. Hoffman and published by Routledge. This book was released on 2020-11-16 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: The game of American football may be the greatest team sport that exists. It epitomizes the need of a "team" first approach to achieve the desired success. Success is often measured as the hoisting of a championship trophy, which involved a journey that required discipline, perseverance, sacrifice, and hard work. These traits are the backbone of success in football, but more importantly they are the backbone or blueprint for success in life. The Science of American Football provides an in-depth discussion on the physiology of the game of American football, including the physiological strain associated with playing in various environmental extremes. Acclimatization, preparation, and medical issues associated with each of these environmental extremes are discussed as well as medical issues occurring during the athlete’s playing career (common sites of injury) and potential risks arising post-career (e.g. neurological dysfunction, arthritic joints, obesity). The book goes on to consider aspects of player selection and preparation, including discussion of evidence-based physical conditioning programs, appropriate nutrition, and specific dietary supplementation for the American football player. The Science of American Football is the first book to focus on the physiology, science, and medical issues associated with the game of American football and will be key reading for students of coaching and exercise science as well as those with a keen interest in understanding the science of American football, such as coaches and players.

Download or read book Comparison of Bilateral and Unilateral Strength in Trained NCAA Division Iii Football Players written by Andrew K. Papirio and published by . This book was released on 2022 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: The bilateral deficit (BD) is a well-established phenomenon describing the difference in force capabilities between bilateral and unilateral movements. The majority of research has used seated machine-based protocols to measure the BD and deduce training implications. However, these are uncommon in modern strength training practices and do not reflect the movement patterns found in sport. The purpose of this study was to use a ground-based multi-joint exercise to determine if a BD was present in trained athletes. Forty trained NCAA Division III football players (20.9 + 0.8 years, 209.7 + 30.1 lb., 71.2 + 2.2 in) completed a bilateral and unilateral 1RM deadlift. Participants were divided into two groups to ensure that fatigue and the order of the 1RM tests did not have any effect. Group A (n = 17) completed the bilateral 1RM deadlift first, Group B (n = 23) completed the unilateral 1RM deadlift first. The remaining test was performed 48-72 hours later to provide adequate rest. Unilateral 1RM values were multiplied by two and compared to the participants’ bilateral 1RM. A significant bilateral deficit was present in both groups (M = 102.5). Participants were significantly stronger on one leg, relatively. Despite perceptions about bilateral facilitation, experienced athletes with a balanced training history appear to experience a BD and possess the capacity to be stronger on one leg. These findings suggest that trained athletes may benefit from unilateral training for the development of strength.

This book was released on 2011 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In recent years the National Collegiate Athlete Association has lessened the amount of time they allow their participating football members to practice in the preseason. Consequently, coaches look for ways to best utilize the time they do have. This study was conducted to determine if there was a significant difference in preseason testing results between the starters and non-starters. Seventy-two members of the Bemidji State University (BSU) football team, 24 in three separate positions, were studied over a three years span, encompassing 33 games to determine of [sic] the starters performed significantly higher than the non-starters in the five fitness tests performed. No such study had been performed at BSU longer than three games prior to this research. Athletes were tested on the 40 yard dash, bench press, vertical jump, pro agility, and the Beaver Run. Results were entered into an SPSS program and compared using an independent samples t-test. There were significant results between the starters and non-starters of the linebacker and the wide receiver group. No such results were found in any of the five preseason fitness tests amongst the defensive back groups. The results of this study indicate there are differences between starters and non-starters in certain position groups and certain tests within those groups. Not all tests were significant and are able to be used to help determine potential starters over non-starters"--Abstract.

This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to investigate whether the isokinetic bench press could discriminate football-playing ability and to correlate the isokinetic bench press with other commonly used football upper and lower body power tests. National Collegiate Athletic Association (NCAA) Division I collegiate football players aged 18-26 years were divided into two groups by player ability: starters (Group 2) and non-starters (Group 1). On separate days, subjects performed the vertical jump, 40-yard dash, one-repetition maximum (RM) bench press and isokinetic bench press at 60, 180 and 300°/s. Pearson Correlation Coefficient analysis revealed significant correlations among all measures in the present study (height, weight, isokinetic peak force at 60°/s, 180°/s and 300°/s, vertical jump, 1-RM bench press and 40-yard dash). Height and weight negatively correlated with all measures, except the 40-yard dash, indicating that taller and/or heavier football players produced higher (slower) 40-yard dash times. Three 1 x 2 ANOVA's (p

This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Strength and conditioning professionals spend a great deal of time and effort trying to improve athletic performance. Even as coaches evaluate each athlete by using the results of a vast battery of tests, there has been considerable speculation and discussion about the physical attributes of Division I football players and their playing status. The purpose of this study was to determine what influence strength, power, and performance tests scores have on an individual's playing status. The Skill group results indicate that power is the most important factor differentiating between starters and non-starters. Simultaneously, the Combo group results indicate that speed is the most important factor differentiating between starters and non-starters. Also, the L.O.S. group results indicate that bodyweight is the most important factor differentiating between starters and non-starters.

This book was released on 2008 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: PURPOSE/HYPOTHESIS: The purpose of this study was to determine if any differences exist between hamstring to quadriceps ratios of offensive and defensive NCAA Division III football players. The research hypothesis was that a difference in hamstring to quadriceps strength ratios would exist between positions, with defensive players having higher hamstring to quadriceps strength than the offensive players. MATERIALS/METHODS: Thirty-five subjects from one NCAA Division III collegiate football team participated in this study. Exclusion criteria included any kne injury sustained in the last 6 months and any health contraindications to exercise. Subjects were also screened for incidence of lower extremity or back injury in the last months. Each subject gave informed consent and completed a demographic intake for prior to participation. A Cybex Norm isokinetic dynamometer was used to access hamstring and quadriceps strength of the players. Testing began with a 5-minute wan up on a cycle ergometer. Each subject then performed 4 trial repetitions followed by t repetitions at 60 deg/sec, 180 deg/sec, and 300 deg/sec. Players were assigned to one the two groups based on their positions: offense(n=16) and defense(n=19). Statistical analysis was performed on the highest recorded torque for each speed. An independent samples t test was used to test the null hypothesis and to analyze the data collected on comparing hamstring to quadriceps ratios in the offensive versus defensive players. The results were reported a Means and Standard Deviations (M ±SD). Statistical significance was set at a p value

Download or read book Predicting Starting Status written by Martin J. Spieler and published by . This book was released on 2006 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Author's abstract: The recruiting process in collegiate football calls for coaches to identify prospective student-athletes who would be most successful at their institution. Humara (2005) argues that while coaches are experts in the identification of physical attributes needed for success, they may lack the ability to identify psychological skills. Niednagel (2004) would contend that in addition to psychological and physical factors, environmental factors also contribute to the ability to succeed. Participants were 108 male football players (35 linemen, 47 tight ends/linebackers, 18 skilled players, 8 special teams) from 6 teams in a NCAA Division I Southeastern conference. Using multivariate analysis of variance and discriminant analysis, the current research attempted to determine factors from demographic information, the Ten-Item Personality Inventory, and the Athletic Coping Skills Inventory-28, that most accurately predicts starting status in collegiate football players. Results showed that there was a significant difference between starters and non-starters for age, high school size, and coping with adversity, predicting starting status 79.6% of the time.
Download or read book The Relationship Between Aerobic Power and Repeated Sprint Ability in Division III Collegiate Football Players written by Joel Reinhardt and published by . This book was released on 2017 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: The purpose of the current study was to examine the relationship between aerobic power and repeated sprint ability. Division III collegiate football players (n = 30) participated in the study. On the first day of testing, each subject completed the Yo Yo Intermittent Recovery Test Level 2 (YYI2). On the second day of testing, each subject completed a repeated sprint test using football specific work to rest ratios that included two rounds of 6 sprints. No significant relationship was found between end stage completed in the YYI2 and percent decrement in round one, round two, or total (p > .05). Two main limitations were identified in the study. The first was that the difficulty level of the YYI2 for the subjects was too high. The second was the lack of concealing from the subjects the number of total sprints that would be completed. While no significant relationship was found, practical implications could be useful for strength and conditioning coaches involved in the physical preparation of collegiate football players.
