Fatigue-Induced Sex Differences For Explosive Neuromuscular Characteristics Of The Plantar Flexors, Ben Dalton

Symposium of Student Scholars

Previous research on fatigue using isometric contractions suggests that females are more fatigue resistant than males, but less is clear regarding fatigue induced by dynamic contractions. PURPOSE: To determine sex differences for explosive voluntary neuromuscular characteristics of the plantar flexors (PFs) during a dynamic fatiguing task. METHODS: Recreationally active males (n=14; 22.4±2.2 yrs) and females (n=15; 20.9±2.5 yrs) performed a fatiguing task of the PFs consisting of 60 maximal isotonic contractions at 30% of their maximal isometric strength using a dynamometer. Peak power (PP), optimal velocity (OV), and optimal torque (OT) were calculated from the first five contractions of the …

The Effect Of Oral Contraceptives On Caffeine Metabolism And Cycling Performance, Annette M. Lemanski

Showcase of Graduate Student Scholarship and Creative Activities

This project objectives were to determine the effects of oral contraceptives and menstrual cycle on the benefits of caffeine supplementation for cycling performance. Seventeen recreationally trained female cyclists completed four trials consisting of 3 kilometer time trials. Subjects ingested either caffeine or a placebo one hour prior to each trial. The magnitude of the ergogenic aid of caffeine was compared between oral contraceptive users and eumenorreheic females. In addition, the effect of caffeine was compared across different phases of the menstrual cycle, specifically the follicular and luteal phases.

The Relationship Between Objective And Subjective Markers Of Training Stress In Ncaa Division I Women Basketball Players, Casey Pederson, Courtney Elliott, James Hutson

Undergraduate Research Conference

An athlete’s training stress score (TSS) is an objective marker of overall training volume and can be determined by tracking total time spent at specific heart rate (HR) zones. Additionally, an athlete’s power factor (PF) or explosive strength is an important marker of performance and can be measured objectively with power testing equipment. While these measures of training stress and performance are important, a coach with limited resources may not have access to the equipment or expertise to measure these variables. On a subjective level, perceived recovery status (PRS) prior to practice and the rating of perceived exertion (RPE) during …

The Effects Of Swimming Training On Arterial Stiffness, Muscular Strength And Cardiorespiratory Endurance In Postmenopausal Women With Stage 2 Hypertension, Steven Scott

UNO Student Research and Creative Activity Fair

Objective:

Aging is associated with progressive decreases in arterial health and function as well as overall fitness. It is crucial to prevent or reduce the negative effects of aging on vasculature and fitness components by implementing appropriate lifestyle interventions, such as exercise training. We examined the effects of a swimming (SWM) regimen on arterial stiffness (pulse wave velocity, PWV), blood pressure (BP), wave reflection (AIx), muscle strength and aerobic capacity in postmenopausal women with stage 2 hypertension.

Methods:

Using a parallel experimental design, participants were randomly assigned to either a SWM (n=52) or non-exercising control group (n=48) for 20 weeks. …

Putting The Athletic Back In The Trainer, Shelby L. Davis

Posters-at-the-Capitol

Athletic Training Students are taught about the benefits of physical activity and how to create specific exercise programs to maintain overall wellness. Although athletic training students have knowledge about the positive effects of physical activity, they continually score lower on activity level scales when compared with the average college student. A rigorous course schedule and long clinical hours seem to be a common factor that play into the poor health habits of the athletic training student. Therefore, the purpose of this study is to determine the variables that negatively affect the exercise habits of undergraduate athletic training students.

Certified Athletic Trainer’S Perceived Comfort Level With Shoulder Reductions, Jessica Pearson, Michael S. Weller

The Research and Scholarship Symposium (2013-2019)

Joint dislocations are a common injury in the athletic world. The shoulder is the most commonly dislocated joint. It is important for health care professionals to be aware of this injury and be able to treat it. Athletic trainers play a vital role in the immediate care of injured athletes. The purpose of this study was to investigate the perceived comfort level of athletic trainers with reducing a shoulder dislocation. The results showed that there was a significant difference between ATC’s perceived comfort level in the 5-10 and 20+ years of experience groups when reducing posterior dislocations (p=.016). Another significant …

Effects Of Footstrike On Low Back Posture, Shock Attenuation, And Comfort In Running, Traci L. Delgado, Emilia Kubera-Shelton, Robert R. Robb, Robbin Hickman, Harvey Wallmann, Janet Dufek

Interdisciplinary Research Scholarship Day

To determine if a change from rearfoot strike (RFS) to forefoot strike (FFS) would change lumbar lordosis, influence shock attenuation, or change comfort levels in healthy recreational/experienced runners.
