Exploring End User Experience: How Can We Achieve Lifelong Engagement With Physical Activity Tracking Devices?, Mohammed Karim Impelee

Masters Theses/Capstone Projects

Activity tracking devices provide biofeedback information and encourage people to be active, however, their long-term usage has been problematic. This study explored the theory of reinforcement techniques and the theory of self- determination to enhance long-term usage of activity tracking devices.

A sample of 43 people was surveyed to examine their experience with activity tracking devices. A multi-regression analysis demonstrated significant results(R square=71.6% Sig level=0.012 N=43). The result indicates how individuals with different orientations likely to perceive the supportiveness of their devices and how likely they were to continue using or stop using their devices. Conclusion: understanding the principles of …

Degrees Of Damage: Quantifying Male Vs. Female Exercise-Induced Muscle Damage Through Magnetization Transfer Ratios, Nicholai Michael Clausius Crawford

Electronic Thesis and Dissertation Repository

No direct, quantitative, and non-invasive markers presently exist to assess exercise-induced muscle damage (EIMD). However, magnetization transfer ratios (MTR), an emerging measurement quantified via magnetic resonance imagery, provide more direct indication of muscle integrity following EIMD. This study compares and correlates the temporal pattern of the MTR to alternative indirect markers of EIMD in male vs. female populations, and subsequently establishes whether there are sex differences in biochemical activity during recovery. The antioxidant properties of estrogen hypothetically minimize muscle trauma, maintain membrane stability, and limit swelling resulting in heightened tissue integrity and resilience to EIMD. Six males and three females …

The Effects Of Massage On Perceived Physical Soreness, Pain And Markers Of Inflammation Following High Intensity Unaccustomed Exercise, Courtney Lynn Crow

Master's Theses

Massage is often recommended to athletes to facilitate recovery and attenuate DOMS. The purpose of this study was to investigate the effects of massage on perceived muscle soreness and pain, inflammatory and immune markers, ROM, and mood state. Fourteen, recreationally active, women participated in a randomized crossover design study, consisting of 1) 60 min. full body massage following unaccustomed exercise and 2) 60 min. of rest. following unaccustomed exercise. Perceived muscle soreness and pain, active range of motion (ROM), mood state, along with blood concentrations of interleukin-6 (IL-6), C-reactive protein (CRP), creatine kinase (CK), and neutrophil count (NC), was assessed …

Upper Body Posture And Pain In Division I Female Volleyball And Softball Athletes, Brittany M. Plunkett Castilla

Dissertations and Theses

Participation in athletics is a popular pastime and form of entertainment. Children often begin to specialize in one sport at a young age in an effort to excel, which increases physical stress and the potential for injuries. Athletes participating in overhead sports are at increased risk of upper body chronic injuries, in part because the shoulder is an unstable hypermobile joint. Posture may also be affected in these athletes because of the demands placed on the upper body. The purpose of this study was to measure the upper body posture in a sample of Division I collegiate volleyball and softball …

Stability Of Isometric Strength Asymmetry And Its Relationship To Sprint And Change-Of-Direction Performance Asymmetry In Division-I Collegiate Athletes, Benjamin H. Gleason

Electronic Theses and Dissertations

The purpose of this dissertation was to evaluate the stability of strength asymmetry over a long-term period (1 year) and investigate the relationship of strength asymmetry to field test performance asymmetry in NCAA division-1 athletes. Isometric mid-thigh pull (IMTP) peak force asymmetry, ground contact time and finish time asymmetries on 10m sprint and 505 agility test performances were also observed. The impact of strength was also investigated in these studies to determine its effect on the magnitude of asymmetry.

In the second study, peak force asymmetry over a one-year period was observed to be a rather volatile quality, with ranges …

Effect Of A 7-Week Rock Climbing Class On Physical Fitness And Performance, Justin Scott Cargo

Masters Theses

The purpose of this study was to assess changes in physical fitness and performance by rock climbing twice a week over a 7-week time period. Rock climbing is on the rise in popularity as seen in the rise of indoor climbing gyms and the increase in rock climbing competitions (Wall, C. B., Starek, J. E., Fleck, S. J., & Byrnes, W. C., 2004). Notably, the International Federation of Sport Climbing has held the Climbing World Championships biennially since the first event in 1991 (Schoffl, Burtscher, & Coscia, 2013), which emphasizes the importance of this research to apply to training programs. …

Acute Effects Of Self-Myofascial Release And Static Stretching On Shoulder Range Of Motion And Performance In Overhead Athletes With Glenohumeral Internal Rotation Deficit, Ryan R. Fairall

Seton Hall University Dissertations and Theses (ETDs)

Purpose: The purpose of this study was to examine the acute effects of a) self-myofascial release (SMR), b) static stretching (SS), and c) the combination of self-myofascial release and static stretching (SMR+SS) on glenohumeral internal rotation range of motion and markers of shoulder performance (i.e. glenohumeral external rotation isometric strength, motor unit recruitment, and throwing velocity) in male softball players with glenohumeral internal rotation deficit (GIRD).

Methods: The sample consisted of 12 male amateur softball players (age: 36.92 ±11.17 years; height: 177.42 ±6.30cm; mass: 87.58 ±18.39kg) who exhibited ≥20° less internal rotation range of motion (ROM) in the throwing shoulder …

Acl Injuries In Female Athletes: Are Prevention Programs The Answer?, Brooke Chandor

Honors Theses

Around 400,000 people tear their anterior cruciate ligaments (ACLs) every year in the United States. The majority of these injuries occur during athletics, and most commonly to females. Their neuromuscular abilities, anatomies, and hormones put female athletes at a much higher risk of ACL injury than male athletes. The current gold standard of treatment, ACL reconstruction, is an imperfect technique at best. It leaves patients with much higher risk of both ACL reinjury and early onset of osteoarthritis. Prevention programs, aimed at reducing the neuromuscular risk factors in female athletes, have proved to effectively reduce the number of noncontact ACL …

Biomechanical Analysis Of Race Walking Compared To Normal Walking And Running Gait, Jaclyn D. Norberg

Theses and Dissertations--Kinesiology and Health Promotion

Human locomotion is phenomenon that is extraordinarily complex. It is evident that a complete description of locomotion involves consideration of kinematics, kinetics, and muscle activity of the extremities in all of their various movements. Race walking (RW) is a form of upright locomotion that differs from normal walking and running by its form dictated by the International Amateur Athletics Federation (IAAF). Despite the similarities to both normal walking (NW) and running (RU), RW has not been the subject of equally intensive investigations.

This study explores the comprehensive biomechanics of race walking and how it compares to NW and RU. A …

The Effects Of Spinal Manipulative Therapy On Isokinetic Strength And Postactivation Potentiation, Grant D. Sanders

Theses and Dissertations--Kinesiology and Health Promotion

Spinal manipulative therapy (SMT) is a therapeutic procedure employed by various healthcare practitioners for alleviating acute and chronic musculoskeletal complaints. This form of treatment is also delivered to enhance the performance and augment the rehabilitation of athletes. However, despite research findings alleging the strength-modulating effects of SMT alongside numerous professional athletes’ positive anecdotal claims concerning its results, the physiological processes to explain its effects remain largely unexplained. Therefore, the purpose of this work was to investigate the effects of SMT in a college-aged sample population with two experiments.

The first study examined the effect of SMT targeting the lumbosacral region …
