The purpose of this study was to quantify the effect of high-top and low-top shoes on ankle inversion kinematics and pre-landing EMG activation of ankle evertor muscles during landing on a tilted surface.

Methods

Thirteen physical education students landed on four types of surfaces wearing either high-top shoes (HS) or low-top shoes (LS). The four conditions were 15° inversion, 30° inversion ...


Delivery And Pitch Type Alter Ground Reaction Forces In Baseball Pitching, Garrett Kass 2014 Pepperdine University

Delivery And Pitch Type Alter Ground Reaction Forces In Baseball Pitching, Garrett Kass

All Undergraduate Student Research

Ground reaction forces (GRFs) exerted on a pitcher in reaction to the push of their legs against the ground create torques about the center-of-mass (CM) and generate the angular momentum necessary to rotate the body, including the segments of the throwing arm. Thus examination of GRFs provides insight into the causal mechanisms responsible for segmental rotation in baseball pitching. PURPOSE: To determine the effects of delivery [wind-up (WU) vs. stretch (ST)] and pitch type [fastball (FB) vs. change-up (CU)] on GRFs in pitching. METHODS: Eight collegiate baseball pitchers (4 right-handed and 4 left-handed) provided voluntary informed consent and threw maximal ...

Effects Of Body Armor And Load Carriage On Lower Limb Joint Movement, Huiju Park, Donna Branson, Adriana Petrova, Semra Peksoz, Carla Goad, Aric J. Warren, Bert Jacobson, Panagiotis Kamenidis

Journal of Human Performance in Extreme Environments

This study investigated the impact of body armor weight and load magnitude and distribution on the lower extremities during walking. Range of motion (ROM) was assessed while seven healthy, male, right-handed, military university students walked while wearing seven different garments of varying weights (0.06 kg, 9 kg, 18 kg, and 27 kg) and load distributions. Decreased pelvic rotation found with an increase in weight implies decreased mobility by restricting the leg’s swing to propel the body forward. Increased ROM for pelvic tilt found with increased weight results from increased forward inclination suggesting an increased possibility for fatigue and ...

Neuromuscular Fatique Following A Singles Badminton Match, Ryan Zengyuan Lin

Theses: Doctorates and Masters

A typical badminton singles match involves numerous intense and high impact movements. Lunges were accounted for approximately 15% of overall movements and were believed to presumably induce significant muscle damage following a match. However, no previous study has investigated changes in knee extensor muscle function after a badminton match.The present study investigated changes in knee extensor neuromuscular function and muscle soreness after a simulated 1-h badminton singles match in relation to the number of lunges performed in the match.

Ten state-level male badminton players were recruited (n=10), with each player played a total of eight simulated 1-h matches ...

Neuromuscular Factors Affecting Stretch-Induced Torque Loss, Gabriel Siqueira Trajano Dr 2014 Edith Cowan University

Neuromuscular Factors Affecting Stretch-Induced Torque Loss, Gabriel Siqueira Trajano Dr

Theses: Doctorates and Masters

The mechanisms underpinning the immediate torque loss induced by acute, static muscle stretching are still not clear. The current research was designed to examine the neuromuscular factors influencing this torque loss. In Study 1, the contributions of central versus peripheral factors to the stretch-induced torque loss were investigated. Measures of central drive, including the EMG amplitude normalised to the muscle compound action potential amplitude (EMG:M), percent voluntary activation (%VA) and first volitional wave amplitude (V:M), and measures of peripheral function, including the twitch peak torque and 20:80 Hz tetanic torque ratio were made before, and immediately and ...


Comparison Of Two Different Sprint Interval Training Work-To-Rest Ratios On Acute Metabolic And Inflammatory Responses, CHRISTOPHER R. HARNISH 2014 Virginia Commonwealth University

Comparison Of Two Different Sprint Interval Training Work-To-Rest Ratios On Acute Metabolic And Inflammatory Responses, Christopher R. Harnish

Theses and Dissertations

High intensity exercise is believed to yield greater results on health and human performance than moderate intensity exercise. Extensive research indicates that not only do high-intensity interval training (HIT) and sprint interval training (SIT) produce significant improvements in cardiovascular fitness and disease, they may be more effective at improving long-term metabolic function, including insulin sensitivity (Si), by producing more mitochondria. Moreover, compliance rates for HIT and SIT participation are reported to be the same or better than traditional moderate intensity exercise. Because lack of time is often cited as major hindrance to exercise participation, SIT is also seen as a ...


Perspectives Of Female Leaders In Athletic Training, Kyle Matthew Momsen 2014 Minnesota State University - Mankato

Perspectives Of Female Leaders In Athletic Training, Kyle Matthew Momsen

All Theses, Dissertations, and Other Capstone Projects

Previous research has found that women face barriers in athletic training and it appears that they are not represented in leadership positions in numbers equal to the demographics of athletic training. The purpose of this research was to explore the leadership experiences and perspectives of female athletic trainers who have earned a leadership position at the highest levels in athletic training. This qualitative investigation utilized semi-structured, open-ended interviews with 12 women that held national leadership positions in athletic training. The data from this investigation suggests that many of the barriers that previously faced women in athletic training have decreased or ...

The Effect Of Stretching And Strengthening On Patellofemoral Pain Syndrome, Heather Hollinger

Departmental Honors Projects

Although there is considerable research on stretches and strengthening exercises that could help improve function, pain, strength, and flexibility associated with the symptoms of patellofemoral pain, more research on how beneficial stretching and strengthening is compared to just stretching is needed. The purpose of this study was to determine the effectiveness of stretching and strengthening as compared to just stretching alone on flexibility, strength, function, and pain in participants with at least 50% of the symptoms and predispositions associated with patellofemoral pain. The design consisted of a control group that completed basic stretching, while the treatment group received stretching and ...


Understanding And Improving Pacing Strategies During Standard Distance Triathlons In Age Group Athletes, Sam Shi Xuan Wu 2014 Edith Cowan University

Understanding And Improving Pacing Strategies During Standard Distance Triathlons In Age Group Athletes, Sam Shi Xuan Wu

Theses: Doctorates and Masters

Pacing is an integral aspect of performance during all exercise, including multi-sport events such as triathlon. However, to date, the optimal pacing strategies to adopt over an entire triathlon, as well as during each specific discipline (i.e. swim, cycle and run), is not well understood. Therefore, the primary purpose of this thesis was to identify and understand current pacing strategies adopted by highly performing triathletes across different triathlon distances. This research aids in identifying pacing strategies that may improve overall performance during triathlon.

In the first study, the influence of sex and race distance on the age-related declines in ...

Relative Importance And Plasticity Of Anatomical And Neuromuscular Factors Affecting Joint Torque Production, Joanne C. Trezise

Theses: Doctorates and Masters

The present research aimed to determine (i) the relative influence anatomical and neuromuscular variables on maximal isometric, concentric and eccentric knee extensor torque (Study 1); (ii) whether the change in strength following a 10-week strength training program is associated with changes in specific anatomical and neuromuscular variables (Study 2a); (iii) whether anatomical and neuromuscular adaptations are dependent on their pre-training magnitudes; and (iv) whether it is possible to ‘predict’ an individual’s adaptation to strength training based on their anatomical and neuromuscular pre-training magnitudes (Study 2b).

The variables assessed throughout the studies include muscle cross-sectional area (CSA), fascicle length and ...


Acute Physiological Effects And Perceived Enjoyment Of A Single Bout Of Aerobic Interval And Continuous Moderate-Intensity Cycling In Overweight And Obese Individuals, Fujie Koh 2014 Edith Cowan University

Acute Physiological Effects And Perceived Enjoyment Of A Single Bout Of Aerobic Interval And Continuous Moderate-Intensity Cycling In Overweight And Obese Individuals, Fujie Koh

Theses: Doctorates and Masters

Aerobic interval training, a form of high intensity interval training, is commonly prescribed to both the general and clinical populations. However, the acute physiological effects from a single bout of aerobic interval session are not fully understood. In training studies, these acute physiological effects may confound actual training adaptations when they occur following the final training session [1]. Furthermore, while recreationally active men perceived aerobic interval training to be more enjoyable than continuous moderate-intensity exercise [2], the preference of overweight and obese individuals has not been extensively researched. Since overweight and obese individuals tend to have lower exercise tolerance, it ...


Role Of Physical Exercise In Reducing Depression And Improving Mental Health In Cancer Survivors, Gregory Levin 2014 Edith Cowan University

Role Of Physical Exercise In Reducing Depression And Improving Mental Health In Cancer Survivors, Gregory Levin

Theses: Doctorates and Masters

Cancer survivors are more than twice as likely as the general population to suffer the debilitating effects of depression. This comorbid condition is associated with several negative consequences, such as reduction in compliance with cancer treatments, and hastened mortality. Recent research has examined the therapeutic effect of exercise on depression and reported excellent results of similar magnitude to those achieved with pharmacotherapy or psychological intervention. However, no research, to date, has examined the effectiveness of exercise on reducing depression in depressed cancer survivors. In order to address this important question this thesis reviewed previous literature in the area of cancer ...


Injured Athletes' Preferences Regarding Source Of Emotional Support, Kristin Kutz 2014 Bowling Green State University

Injured Athletes' Preferences Regarding Source Of Emotional Support, Kristin Kutz

Honors Projects

Athletes often experience emotional distress as a result of an injury. Feelings of loss, decreased self-esteem, frustration, and anger are not uncommon. Athletic trainers (ATs) who work with injured athletes are focused on helping the progression of athletes' physical healing, but their role in helping athletes emotionally and psychologically is often unclear. There are twelve Athletic Training Education Competencies that the National Athletic Training Association requires to be taught to undergraduate AT students, one of them being psychosocial intervention and referral. However, little research has been done to define the exact role of ATs in this area, as well as ...
