The Effect Of Kinesiology Tape Application Duration On Endurance Of Knee During An Isotonic Fatiguing Flexion/Extension Exercise, En Yi Wu

Theses and Dissertations

Kinesiology Tape (KT) is an elastic athletic tape and is popular among athletes as it was claimed that it can to be worn for several days and is capable of preventing injuries, improving rehabilitation processes, improving muscle oxygenation levels, and enhancing muscle performance. The goal of this study was to determine if there was any potential enhancing effect of KT on joint endurance in healthy subjects, in particular with respect to time to fatigue (TTF), muscle oxygenation, and muscle activity in fatiguing knee flexion/extension exercise across sessions.

Fourteen healthy male subjects with no previous history of knee injury participated in …

Reproducibility And The Effects Of Exercise On The Endurance Index, Michael Dean Smith, Jr.

Theses and Dissertations

Background: The Endurance Index (EI%) is a method to objectively assess a muscle’s ability to resist fatigue. The purpose of these studies was to determine the reproducibility of the EI% and determine the influence of muscular fatigue on the EI%. Methods Study 1: sixteen apparently healthy participants (18-30yrs) completed three nonconsecutive visits each with 3 bouts of 5-minute electrical muscle stimulations (EMS) and accelerometer-based mechanomyography (aMMG) of the vastus lateralis at 4 Hz and low amperage (25-35mA) on the hamstrings of the dominant leg; peak torque was measured at each visit. Study 2: fifteen apparently healthy participants (ages 18-30yrs) …

The Effects Of A Short-Term Endurance Training Program With Blood Flow Restriction Cuffs Versus Acsm Recommended Endurance Training On Arterial Compliance And Muscular Adaptations In Recreationally Active Males, Brittany N. Esparza

Theses and Dissertations

RESULTS: Significant time and group interaction found in cardiac ejection time (p<.05). Significant condition difference between blood flow restriction (BFR) and control for heart rate (HR) max (p=.05) and maximum oxygen consumption (VO2) (p<.05). Significant time difference found in pulse wave velocity femoral to distal (p<.05). Significant repetition main effect (p<.01) for root mean square (RMS) and median frequency (MDF) of Thorstensson. Significant time and group interaction in vastus lateralis of MDF (p<.01). Significant repetition main effect for RMS and MDF ratio (p<.01) Significant time and repetition interaction in vastus lateralis of RMS ratio (p<.03)

CONCLUSION: The BFR session showed improvement in both post HR max and post VO2 in comparison to the control group. This may have been caused by increased tolerance to pain/metabolic by-products for HR and increased efficiency at extracting oxygen for VO2

The Acute Effects Of Aerobic Exercise With Blood Flow Restriction Cuffs On Arterial Compliance In Males And Females, Maria M. Gonzalez

Theses and Dissertations

RESULTS: Significant condition*gender interactions found in in SBP (p<.05), PR (p<.01), SVR (p<.01), SpO2 (p<.05), PWV carotid to femoral (p<.03), and PWV femoral to distal (p<.02). Significant condition*time interactions were found in SBP (p<.01), DBP (p<.01), MAP (p<.01), SV (p<.01), CO (p<.01), SVR (p<.01), TVI (p<.01), HR (p<.01), and SAE (p<.01). Significant condition main effects were found in SBP (p<.02), DBP (p<.03), PR (p<.03), SV (p<.01), CO (p=.01), SVR (p<.01), TVI (p<.01), HR (p<.01), and SAE (p<.03) as well as a condition trend in PWV femoral to distal (p=.06). Significant time main effects were found in SBP (p<.01), MAP (p<.04), PP (p<.01), PR (p<.01), CO (p<.01), SVR (p<.01), TVI (p<.01), HR (p<.01), SpO2 (p<.01), LAE (p<.03), and PWV femoral to distal (p<.01).

CONCLUSION: The 60 min session at a moderate aerobic intensity might have the potential to improve arterial elasticity more than a 20 min BFR session.

Perceptions And Practices Of Hydration In Triathlon, Corey Stephen O'Connor

Perceptions and Practices of Hydration in Triathlon

Corey S. O'Connor, David Q. Thomas, Kelly R. Laurson, Dale D. Brown. Illinois State University, Normal, IL

Purpose: To examine where triathletes obtain information regarding hydration, if their performances have been affected by dehydration, and how they monitor their hydration status. Methods: Two hundred and two participants (age=38.70 ± 9.73 years) from various triathlon groups in Illinois participated in the study. Each participant was asked to complete an electronic survey. The survey was composed of twenty seven items and was developed by O'Neal (2011). The survey was modified for triathletes and seven questions …

Kinematic Changes During A Marathon For Fast And Slow Runners, Maggie Man-Yee Chan-Roper

Theses and Dissertations

The purpose of this study was to describe kinematic changes that occur during an actual marathon. We hypothesized that (1) certain running kinematic measures would change between miles 5 and 25 of a marathon and (2) fast runners would demonstrate smaller changes than slow runners. Subjects (n = 179) were selected according to finish time (Range = 2:20:47 to 5:30:10). Two high-speed cameras were used to measure sagittal-plane kinematics at miles 5 and 25 of the marathon. The dependent variables were stride length, ground time, peak knee flexion during support and swing, and peak hip flexion and extension during swing. …
