Power Reserve Following Ramp-Incremental Cycling To Exhaustion: Implications For Muscle Fatigue And Function, Michael D. Hodgson

Electronic Thesis and Dissertation Repository

In ramp-incremental cycling exercise, some individuals are capable of producing power output (PO) in excess of that produced at their limit of tolerance (LoT) while others cannot. This study sought to describe the: 1) prevalence of a “power reserve” within a group of young men (n=21; mean ± SD: age 25±4 years; V̇O_2max45±8 ml•kg^-1•min^-1); and 2) muscle fatigue characteristics of those with and without a power reserve. Power reserve was determined as the difference between peak PO achieved during a ramp-incremental test to exhaustion and maximal, single-leg isokinetic dynamometer power. Pre- versus post-exercise changes …

Current Research And Statistical Practices In Sport Science And A Need For Change, Jake R. Bernards, Kimitake Sato, G. Gregory Haff, Caleb D. Bazyler

ETSU Faculty Works

Current research ideologies in sport science allow for the possibility of investigators producing statistically significant results to help fit the outcome into a predetermined theory. Additionally, under the current Neyman-Pearson statistical structure, some argue that null hypothesis significant testing (NHST) under the frequentist approach is flawed, regardless. For example, a p-value is unable to measure the probability that the studied hypothesis is true, unable to measure the size of an effect or the importance of a result, and unable to provide a good measure of evidence regarding a model or hypothesis. Many of these downfalls are key questions researchers strive …

A Public At Risk: Personal Fitness Trainers Without A Standard Of Care, Margaret E. Ciccolella, J. Mark Van Ness, Tommy Boone

Margaret Ciccolella

In 2002, an overweight, sedentary, and middle-aged man suffered a heart attack during his first workout with his “certified” personal trainer. During the workout, the man repeatedly asked to stop because he was experiencing fatigue, heat, thirst, breathlessness, and chest pain. The trainer responded to requests to stop and complaints of fatigue by questioning his client’s masculinity and by continuing the workout. In the lawsuit that followed (Rostai v. Neste Enterprises, 2006), the court did not have the option to consider a statutorily defined standard of care since no licensing requirements existed for those who design and/or lead fitness programs. …

Neuromuscular Training Improves Lower Extremity Biomechanics Associated With Knee Injury During Landing In 11-13 Year Old Female Netball Athletes: A Randomized Control Study, Amanda J. Hopper, Erin Haff, Christopher Joyce, Rhodri S. Lloyd, G. Gregory Haff

Research outputs 2014 to 2021

The purpose of this study was to examine the effects of a neuromuscular training (NMT) program on lower-extremity biomechanics in youth female netball athletes. The hypothesis was that significant improvements would be found in landing biomechanics of the lower-extremities, commonly associated with anterior cruciate ligament (ACL) injury, following NMT. Twenty-three athletes (age = 12.2 ± 0.9 years; height = 1.63 ± 0.08 m; mass = 51.8 ± 8.5 kg) completed two testing sessions separated by 7-weeks and were randomly assigned to either a experimental or control group. Thirteen athletes underwent 6-weeks of NMT, while the remaining 10 served as controls …

E-Visits For Early Post-Operative Visits Following Orthopaedic Surgery Can They Add Efficiency Without Sacrificing Effectiveness, William G. Jeffery

Electronic Thesis and Dissertation Repository

We asked 217 sport surgery and 135 total knee arthroplasty (TKA) patients to complete a questionnaire (e-Visit) before attending their two and six-week post-operative appointment. Our primary objective was to use the questions asked of patients prior to their appointment to develop a model that could be used as web-based e-Visit to predict early post-operative adverse events. Gold standard comparison was the surgeon’s opinion as to the presence or absence of an event at follow-up. Secondary objective was evaluation of a simplified model. We found good area under the curve (AUC) statistics (0.76 (95% CI 0.69 - 0.84) and 0.80 …

Center for Brain, Biology, and Behavior: Faculty and Staff Publications

We sought to investigate the one-week and within-session reliability of the instrumented balance error scoring system test and the concurrent validity/one-week reliability of two neurocognitive assessments available through C3 Logix. (n = 37) Participants completed two balance error scoring system tests separated by the Trails A, Trails B, and Symbol Digit Modality test available through C3 Logix, and with paper and pencil. We found that the instrumented balance error scoring system test demonstrated strong one-week reliability and that neuropsychological tests available through C3 Logix show acceptable concurrent validity with standard (comparable) paper and pencil measures.

Research outputs 2014 to 2021

This study investigated the effects of eccentric phase-emphasis strength training (EPE) on unilateral strength and performance in 180- and 45-degree change of direction (COD) tasks in rugby union players. A 12-week cross-over design was used to compare the efficacy of resistance training executed with 3 s eccentric duration (EPE, n = 12) against conventional strength training, with no constraints on tempo (CON, n = 6). Players in each condition were categorised as ‘fast’ (FAST) or ‘slow’ (SLOW) using median trial times from baseline testing. Players recorded greater isometric strength improvements following EPE (ES = − 0.54 to 1.80). Whilst these …

Making A Difference: The Role Of Global Sports Organizations, Shirmeen Ahmad

The Eastern Illinois University Political Science Review

Global Sports Organizations play their own part in International Relations providing policies, entertainment, and competition. One of the main questions is how much of an impact do they have in IR. Using two prominent theories in International Relations, realism and constructivism, this research conducts two case studies on the International Olympic Committee and the Federation Internationale de Football Association to see which one proves true. Three hypotheses shape these studies: are states controlling the agenda, how strong is the leadership of the president, and do the organizations push their own initiatives independently. After testing these, we see global sports organizations …

Parent Perceptions Of A Child Physical Activity Initiative In A Rural Community., Katie F. Leslie, Kristi M. King, Richard W. Wilson, Patricia Gagne, V. Faye Jones

Kristi King

This study assessed the extent to which a community-based intervention developed for children impacted parent perceptions and behaviors toward physical activity in a rural community. Focus groups and individual interviews were conducted with parents of children who participated in physical activity programs. Analysis revealed an increased community awareness surrounding physical activity following program implementation. Parents and children encouraged each other to be physically active. Ecological barriers and enabling factors to adult physical activity were identified these findings indicate a bidirectional influence between parent and child physical activity and the need for community facilities where families can be active together.

Comparisons Of Perceived Training Doses In Champion Collegiate-Level Male And Female Cross-Country Runners And Coaches Over The Course Of A Competitive Season, Kyle Barnes

Funded Articles

Background: Session rating of perceived exertion (sRPE) is a practical tool for coaches to assess internal training load of their athletes. In a sport like cross-country running, that is individual in nature, but has a team training and competition component, information about the association between external and internal load is lacking. Furthermore, there is a need for studies that examine perception of training doses across multiple training cycles including the competitive season as well as between male and female athletes.

Methods: Session RPE, duration, and training load (TL_RPE = sRPE × duration) of 25 highly trained male …

International Journal of Aquatic Research and Education

New Zealand youth are over-represented in drowning statistics yet little is known about their understanding of water safety, especially in surf beach context. This study aimed to ascertain current youth surf safety knowledge, specifically rip current awareness, explore self-reported competencies and confidence when surf swimming, and examine youth behaviour when at the beach. A cross-sectional survey was conducted among senior high school students (n = 599) in Auckland, New Zealand. Over half (58%) reported they were unable to swim > 100 m in a pool. Males and students of European-New Zealand and Maori (New Zealand’s indigenous population) heritage were most …

Measuring Australian Children’S Water Safety Knowledge: The National Water Safety Quiz, Amy E. Peden, Richard Charles Franklin, Justin Scarr

International Journal of Aquatic Research and Education

Water safety knowledge levels of Australian children are poorly understood. Royal Life Saving developed an online National Water Safety Quiz (NWSQ) as an interactive means of determining water safety knowledge amongst Australian primary school children (ages 5 to 12 years). Over a period of 8 months, a total of 4,215 children participated in the NWSQ. The NWSQ identified areas of water safety where knowledge was poor including the topics of CPR, swimming, and river safety. Children achieved a better result as they aged. Females out-performed males overall and specifically from ages 10-12 years. Children from independent schools performed better. This …

Matthew Vukovich

Iron deficiency is prevalent among endurance athletes, particularly females. Low iron may compromise oxygen delivery and physical performance. Vegetarianism, desire for convenience, and perceived health risks associated with red meat contribute to low bioavailable iron intakes. The purpose of this study was to examine if lean beef supplementation would maintain iron status, improve body composition and increase performance of distance runners after 8 weeks. Twenty-eight (14 female) Division-I cross-country runners were stratified by iron status, use of iron supplements, and gender, and randomized into a control (n = 14) and intervention group. All participants maintained their typical diet and consumed …

The Effect Of Six Days Of Dietary Nitrate Supplementation On Performance In Trained Crossfit Athletes, Samuel J. Kramer, Daniel A. Baur, Maria T. Spicer, Matthew D. Vukovich

Matthew Vukovich

Background: While it is well established that dietary nitrate reduces the metabolic cost of exercise, recent evidence suggests this effect is maintained 24 h following the final nitrate dose when plasma nitrite levels have returned to baseline. In addition, acute dietary nitrate was recently reported to enhance peak power production. Our purpose was to examine whether chronic dietary nitrate supplementation enhanced peak power 24 h following the final dose and if this impacted performance in a heavily power-dependent sport. Methods: In a double-blind, randomized, crossover design, maximal aerobic capacity, body composition, strength, maximal power (30 s Wingate), endurance (2 km …

Effect Of Different Collegiate Sports On Cortical Bone In The Tibia, L. A. Weidauer, M. M. Eilers, T. L. Binkley, M. D. Vukovich, B. L. Specker

Matthew Vukovich

Objectives: The purpose of this study was to determine the effect of sports participation on cortical bone in the tibia. Methods: 53 female collegiate athletes (25 cross-country, 16 soccer, and 12 volleyball) and 20 inactive controls had the left distal 20% tibia scanned by pQCT. Cortical volumetric BMD (vBMD) was measured within the cortical shell at the anterior, posterior, medial, and lateral regions and standard deviations were calculated. Results: Total vBMD was greater in the control group (1161±5 mg/mm3) than each of the sports (p<0.05). Soccer players (1147±5 mg/mm3) had greater vBMD than volleyball players (1136±7 mg/mm3) (p<0.05), but similar to cross-country runners (1145±5 mg/mm3). Cortical thickness was greatest in soccer players (4.1±0.1 mm), while cross-country and control subjects (3.8±0.1 mm) had greater thickness than volleyball players (3.4±0.1 mm)(p<0.05). Periosteal circumference was greater in volleyball players (71±1.4 mm) than soccer, cross-country, and control subjects (68±0.9, 69±0.8, and 66±1 mm, respectively; all, p<0.05). vBMD variation within the cortical shell was greater among control subjects (70±6 mg/cm3) than each of the athlete groups, with soccer players having lower variation than cross country runners (within-in person SD 36±6 mg/cm3 and 54±5 mg/cm3 respectively; p<0.05). Conclusion: These results indicate bone geometry and distribution within the cortical shell of the tibia …

This guest editorial leads off and introduces the subsequent scientific review.

From Swimming Skill To Water Competence: Towards A More Inclusive Drowning Prevention Future, Robert Keig Stallman, Kevin Moran Dr, Linda Quan, Stephen Langendorfer

International Journal of Aquatic Research and Education

Brenner, Moran, Stallman, Gilchrist and McVan, (2006) recommended that “swimming ability be promoted as a necessary component of water competence, but with the understanding that swimming ability alone is [often] not sufficient to prevent drowning” (p. 116). Tradition and expert opinion are no longer enough. Science can now help us select essential competencies. What does research evidence show us about the protective value of specific individual personal competencies? Since the term “water competence’’ was coined by Langendorfer and Bruya (1995) and adapted for drowning prevention by Moran (2013), it has gained in use and acceptance. As a construct, it is …
