The total running distance covered (TD), the high metabolic load (HMLD), the number of high metabolic load efforts (HMLE) were progressively reduced from MD-4 to MD-1 but the values of these variables were always inferior to MD (ES: -3.79 to −1.11). …

Player-Coach Perceptions Of Internal Load, Exertion, And Recovery In Collegiate Male Soccer Players, Michelle L. Eisenman

College of Graduate Studies: Theses & Dissertations

Periodization of athlete training load to improve performance and maximize recovery, while reducing injuries and overtraining, is essential in team sports. Understanding internal load responses and monitoring athlete exertion and recovery can help coaches during a competitive season. Recovery Status (PRS) and Rating of Perceived Exertion (RPE) are two subjective scales used to help quantify training load and recovery. These scales are more useful if there is an agreement between coaches (C) and players (P) assessment of intensity and recovery. PURPOSE: To assess subjective measures (PRS and RPE scores) from P and C during a 13-week competitive soccer season. Furthermore, …

The Use Of A Functional Test Battery As A Noninvasive Method Of Fatigue Assessment, Steven Hughes, Dale W. Chapman, G. Gregory Haff, Sophia Nimphius

Research outputs 2014 to 2021

To assess whether a battery of performance markers, both individually and as group, would be sensitive to fatigue, a within group random cross-over design compared multiple variables during seated control and fatigue (repeated sprint cycling) conditions. Thirty-two physically active participants completed a neuromuscular fatigue questionnaire, Stroop task, postural sway, squat jump, countermovement jump, isometric mid-thigh pull and 10 s maximal sprint cycle (Sprintmax) before and after each condition (15 min, 1 h, 24 h and 48 h). In comparison to control, larger neuromuscular fatigue questionnaire total score decrements were observed 15 min (5.20 ± 4.6), 1 h (3.33 ± 3.9) …

The Application Of Maximal Mean And Critical Speed And Metabolic Powers For The Quantification Of External Load In Soccer, Cameron Nicholas Lord

Theses: Doctorates and Masters

In Association football, often referred to as “soccer”, competitive match play is typically known to represent the greatest physical demand that players experience. The demands associated with match running performance may impact training outcomes and injury risk. As a result, practitioners evaluate these demands to ensure that performance is optimised. To assist in this process, global positioning systems (GPS) are typically used to quantify displacement variables and, more recently, the interaction between running speed and acceleration. However, traditional player monitoring methods tend to apply identical and somewhat arbitrary displacement, velocity and acceleration bands to describe movement “intensity”, and thus to …

Effects Of Headgear On Concussions In Soccer Players, Bayley Pendleton

Thinking Matters Symposium Archive

Concussions have become a hot topic among athletic health care, but there is still a great deal to learn. One specific population has been studied and research produced showing the effects of wearing protective headgear. For some reason, adolescent soccer players are more apt to suffer a concussion. Taking steps to reduce recovery time and make concussions less common is something that should be addressed. The studies done showing the effects of headgear in adolescent soccer players is a topic that needs to be more widely known.

Rumination And Performance In Dynamic, Team Sport, Michael M. Roy, Daniel Memmert, Anastasia Frees, Joseph R. Radzevick, Jean Pretz, Benjamin Noël

Management Faculty Publications

People high in rumination are good at tasks that require persistence whereas people low in rumination is good at tasks that require flexibility. Here we examine real world implications of these differences in dynamic, team sport. In two studies, we found that professional male football (soccer) players from Germany and female field hockey players on the US national team were lower in rumination than were non-athletes. Further, low levels of rumination were associated with a longer career at a higher level in football players. Results indicate that athletes in dynamic, team sport might benefit from the flexibility associated with being …

Biomechanical Investigation Of Elite Place-Kicking, Chase M. Pfeifer

Department of Mechanical and Materials Engineering: Dissertations, Theses, and Student Research

Many studies aim to understand the fundamentals of kicking commonly displayed by soccer players [4,6,10,16,17,18,24,25,28,29,30,34,36,38,40]. Of those studies, most are limited to a two-dimensional (2D) analysis using high-speed cameras for position tracking or utilizing electromyography to observe the activity of select muscles [4,6,18,25,29,36]. The few studies that investigate kicking using a three-dimensional (3D) model are limited in their position tracking capabilities and focus mainly on joint flexion potentials and foot speed.

This dissertation is a comprehensive biomechanical analysis (kinematic and EMG) of the field-goal place-kicking techniques of four elite kickers in American football. Data were compared and contrasted with ball …

Coaching And Concussions: Prevention, Education, And Perspective, Colby J. Felts

Honors Thesis

The large participation of players and coaches in football has made it one of the most popular sports in America. Concussions have specifically gained national attention in football due to frequent, high impact collisions. A concussion injury poses a unique threat in high school football because of the developing adolescent brain and high participation numbers. Additionally, lack of medical personnel to diagnose concussions at the high school level imposes a legal duty on the coaches. The thesis develops a recommended plan of action for directors of Iowa high school football to assist in preserving the future of the sport. A …

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: …

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 …
