PURPOSE: To determine if RAEs exist in elite Olympic weightlifters from the past five Olympic Games. METHODS: Using retrospective competition data from the International Weightlifting Federation database a total of 953 Olympic Weightlifters (595 males and 358 females) who competed in the Olympic Games between 2000 and 2016 were included in this study. Weightlifters who competed in multiple Olympic Games were only counted once and duplicates were removed from this investigation. The weightlifters were divided into subset weight classes; men lightweight (56kg, 62kg, and 69kg), men middleweight (77kg, 85kg, and 94kg), men heavyweight (105kg and 105kg+), women lightweight (48kg, 53kg, …

Female High School Athlete's Confidence About Their Future In College Athletics, Adam Potter

Master's Theses & Capstone Projects

Female athletes may begin at an early age in a sport and find success, but in many cases, there is a disconnect somewhere before entering college where females feel less confident and discontinue their athletic career before college. Some studies have looked at female athletes and their confidence level, however, there is more research that needs to be done to determine if females feel confident that they have the same opportunities available in college as their male counterparts. This study was designed to explore female athletes’ confidence level for their future in college sports. Data was gathered from female athletes …

Difference In Participation In Club Volleyball Prior To College And Receiving Collegiate Volleyball Athletic Scholarships In The Midwest, Lindsey L. Smith

Undergraduate Research Journal

Club volleyball participation has become a popular method in gaining exposure in order to reach the collegiate level. Obtaining a collegiate athletic scholarship is very competitive in today’s globalized world of sports, especially in volleyball as youth participation continues to climb. Volleyball is becoming increasingly more demanding at younger ages, with longer seasons and more specialized hours in elite training. The forecasted product are elite athletes who stand out above the rest, but at a certain cost. Not only are club volleyball programs time-consuming, but very expensive, preventing equal opportunity to athletes. The hypothesis is collegiate volleyball players who participated …

Reducing Aerodynamic Drag By Adopting A Novel Road-Cycling Sprint Position, Paul F. J. Merkes, Paolo Menaspa, Chris R. Abbiss

Research outputs 2014 to 2021

Purpose:

To assess the influence of seated, standing, and forward-standing cycling sprint positions on aerodynamic drag (CdA) and the reproducibility of a field test of CdA calculated in these different positions.

Methods:

A total of 11 recreational male road cyclists rode 250 m in 2 directions at around 25, 32, and 40 km·h.

Results:

A main effect of position showed that the average CdA of the 2 d was lower for the forward-standing position (0.295 [0.059]) compared with both the seated (0.363 [0.071], P = .018) and standing positions (0.372 [0.077], P = .037). Seated and standing positions did …

Kinetics And Kinematics Of The Squat And Step-Up In Well-Trained Rugby Players, Brendyn B. Appleby, Robert U. Newton, Stuart J. Cormack

Research outputs 2014 to 2021

The purpose of this study was to compare and contrast the kinetics and kinematics of squat and step-up performance in well-trained athletes. Triaxial ground reaction force (GRF) and 3D kinematic data were collected in 4 maximal effort repetitions each at 70, 80, and 90% of 1 repetition maximum (1RM) of squat and step-up. The difference in concentric phase kinetics and kinematics between the squat and step-up was compared using effect sizes (ES ± 90% confidence limits [CLs]) classified as: less than 0.2 as trivial; 0.2-0.6 as small; 0.6-1.2 as moderate; and 1.2-2.0 as large. Where the 90% CL crossed negative …

General Strength And Muscular Endurance: Relationship To V1- And V2-Skate Skiing Economy In Collegiate Cross-Country Skiers, Ian Torchia

All NMU Master's Theses

Introduction Cross-country skiing is a power-endurance sport requiring upper and lower body activation for propulsion across the ground. While high aerobic markers such as VO_2max and lactate threshold are important performance indicators, recent research has demonstrated the importance of full-body general strength and muscular endurance in skiing success. The purpose of this study was to examine the relationship of strength indices via a full-body series of muscular endurance tests, as well as a general 1-RM strength test, to VO₂ skiing economy utilizing the V1- and V2-skate technique.

Methods Oxygen uptake was measured during baseline and economy testing on …

Differential Effects Of Aging And Physical Activity On Corticospinal Excitability Of Upper And Lower Limb Muscles, Vianney Rozand, Jonathon William Senefeld, Christopher W. Sundberg, Ashleigh E. Smith, Sandra K. Hunter

Exercise Science Faculty Research and Publications

Corticospinal tract excitability can be altered by age, physical activity (PA), and possibly sex, but whether these effects differ between upper and lower limb muscles is unknown. We determined the influence of age, PA, and sex on corticospinal excitability of an upper limb and a lower limb muscle during submaximal contractions by comparing stimulus-response curves of motor evoked potentials (MEPs). Transcranial magnetic stimulation (TMS) was used to evoke stimulus-response curves in active muscles by incrementally increasing the stimulator intensity from below the active motor threshold (AMT) until a plateau in MEP amplitudes was achieved. Stimulus-response curves were analyzed from the …

Cluster Set Loading In The Back Squat: Kinetic And Kinematic Implications, Alexander Wetmore, John P. Wagle, Matt L. Sams, Christopher Taber, Brad H. Deweese, Kimitake Sato, Michael H. Stone

Exercise Science Faculty Publications

Cluster set loading in the back squat: Kinetic and kinematic implications. J Strength Cond Res XX(X): 000–000, 2018—As athletes become well trained, they require greater stimuli and variation to force adaptation. One means of adding additional variation is the use of cluster loading. Cluster loading involves introducing interrepetition rest during a set, which in theory may allow athletes to train at higher absolute intensities for the same volume. The purpose of this study was to investigate the kinetic and kinematic implications of cluster loading as a resistance training programming tactic compared with traditional loading (TL). Eleven resistance-trained men (age = …

Dance As A Protective Measure Against The Cognitive And Physical Declines Associated With Aging: A Proposed Study, Sarah M. Schwanz, Jeffrey Holmes, Jessica Grahn

Western Research Forum

Background:

Dance is considered a multimodal activity in that it requires both physical and cognitive engagement. Combining physical activity with music may have a synergistic effect, enabling dance to enhance physical and cognitive functions more than music and physical activity alone. The positive changes attributed to dance training such as improved visuospatial and motor ability, high coordination, greater balance, and increased cognitive ability may also benefit individuals as they age.

Methods:

This proposed study will examine whether dance training has the potential to protect against age-related cognitive and physical decline by assessing the cognitive and physical domains that show decline …

Where On Ice? Algorithmically Deconstructing Nhl Shot Locations As A Method For Player Classification, Devan Becker, Douglas G. Woolford, Charmaine B. Dean

Western Research Forum

Where do hockey players shoot from? How does this vary from player to player? We present the results of a study that uses data-driven statistical methods to investigate these questions. The locations of shots by National Hockey League (NHL) players from 2011 to 2017 are analyzed using a combination of an image recognition algorithm and spatial statistical methodology. An unsupervised classifier is applied to output from a spatial point process model in order to determine which shot locations best characterize a given player. We define the number of regions a priori, but the image recognition algorithm chooses the shape …

The Association Of Handgrip Strength And Mortality: What Does It Tell Us And What Can We Do With It?, Samuel L. Buckner, Scott J. Dankel, Zachary W. Bell, Takashi Abe, Jeremy P. Loenneke

Faculty and Student Publications

© Copyright 2019, Mary Ann Liebert, Inc., publishers 2019. The relationship between grip strength and mortality is often used to underscore the importance of resistance exercise in physical activity guidelines. However, grip strength does not appear to appreciably change following traditional resistance training. Thus, grip strength could be considered reflective of strength independent of resistance exercise. If true, grip strength is not necessarily informing us of the importance of resistance exercise as an adult, but potentially highlighting inherent differences between individuals who are stronger at "baseline" compared to their weaker counterpart. The purpose of this article is to discuss: (1) …

Technical Freediving: An Emerging Breath-Hold Diving Technique, Derek Covington, Robert H. Lee, Steven Toffel, Alberto Bursian, Kirk Krack, Chris Giordano

Journal of Human Performance in Extreme Environments

Technical freediving can be defined as freediving augmented by the use of oxygen-enriched gases or oxygen before, during, or after a freedive. As a result of these techniques, breath-hold divers can visit and enjoy underwater wrecks, reefs, and other diving locations previously located at depths unreachable to apnea divers. By pre-breathing oxygen-enriched gases in conjunction with hyperventilation—which decreases the partial pressure of carbon dioxide (PCO2)—the technical freediver now has additional oxygen to facilitate aerobic respiration during the dive. In addition, pre-breathing oxygen decreases tissue nitrogen tensions, which limits inert gas loading and decreases the risk of decompression sickness (DCS). Finally, …
