Quantifying And Comparing The Head Impact Biomechanics Of Different Player Positions For Canadian University Football, Kody Campbell
Quantifying And Comparing The Head Impact Biomechanics Of Different Player Positions For Canadian University Football, Kody Campbell
Electronic Thesis and Dissertation Repository
Differences between Canadian and American football could affect the magnitudes of head impacts and risk of concussion to Canadian players. This study sought to quantify and compare the number, magnitude, and location of impacts that Canadian University football players of different positions experienced during games and practice in a season. A kinematic measuring device collected the linear accelerations and rotational velocities of the head from impacts experienced by players competing in practices and games. The impact magnitudes that were experienced in games were significantly larger than in practice. The offensive back position and wide receiver position had significantly larger peak …

Impact Testing Of Youth-Level Helmets Versus College-Level Helmets, Nicole Hermann
Industrial Technology and Packaging
With so many studies being conducted on professional football players regarding concussions and other related brain injuries, it’s amazing that such an important demographic has been missed. While NFL players are just as subjected to serious injuries as anyone else or even more so, it is important to remember that these players are outfitted, in most cases, with top-of-the-line equipment -- especially their helmets. If the focus is shifted to a younger demographic, youth football players in middle school and high school, the equipment is far less advanced and in a vast majority of cases, has been previously used by …

Of all sports, football accounts for the highest incidence of concussion in the US due to the large number of athletes participating and the nature of the sport. While there is general agreement that concussion incidence can be reduced through rule changes and teaching proper tackling technique, there remains debate as to whether helmet design may also reduce the incidence of concussion. A retrospective analysis was performed of head impact data collected from 1833 collegiate football players who were instrumented with helmet-mounted accelerometer arrays for games and practices. Data were collected between 2005 and 2010 from 8 collegiate football teams: …
Lower Limb Fatigue Asymmetry Of Preferred And Non-Preferred Legs After A Repeated-Sprint Test In Football Players With Previous Hamstring Injury, Cameron Lord
Theses: Doctorates and Masters
Football is the most widely played sport in the world and is thus associated with the highest total number of injuries of all sports. 12% of all football injuries are to the hamstrings, as this muscle group is subjected to constant stress during training and match play performance (Ekstrand, Hägglund, Waldén, 2011; Woods, Hawkins, Maltby, Hulse, Thomas & Hodson, 2004). While the influence of limb dominance has been extensively examined as a risk factor for injury in upper limb-dominant sports (e.g. badminton, tennis and baseball), little research has focussed on the dominance in the lower limbs. Since almost all footballers …
Comparison Of The Physical, Physiological And Perceptual Demands Of Small-Sided Games And Match Play In Professional Football Players, Stephen Hissey
Comparison Of The Physical, Physiological And Perceptual Demands Of Small-Sided Games And Match Play In Professional Football Players, Stephen Hissey
Theses: Doctorates and Masters
The physical and technical requirements of a range of small-sided football (soccer) games (SSGs) have previously been examined in order to compare their requirements to competitive match play. SSGs are used to combine the technical, tactical and physical components of normal match play in training in order to make the training sessions specific to football. However, most previous research has focused on youth players and it is known that the playing patterns, and thus session outcomes, are different for elite players. Consequently, research examining elite players is required in order to improve our understanding of the use of SSGs in …
Quantification Of Eccentric Load Using Accelerometer Imbedded In Gps, Chow Chea Yeo
Quantification Of Eccentric Load Using Accelerometer Imbedded In Gps, Chow Chea Yeo
Theses: Doctorates and Masters
Global positioning system (GPS) with a triaxial accelerometer is widely used to monitor movements of athletes in games and training, and “body load” (BL) representing the accumulation of the rate of changes in three planes of movements is obtained to determine the training load of a session. Deceleration, change of directions and stopping require eccentric contractions of leg muscles, potentially causing muscle damage and affecting athletic performance. Thus, it is important to monitor eccentric loading in games and training. A variable known as “eccentric index” (EI) purports to be a better representation of eccentric loading than BL. However, it is …
