Comparing The Effects Of Pneumatic Compression And Blood Flow Restriction On Muscle Recovery, Jessica Pontarollo, Haneef Zakee, Bailey Mclagan, E Todd Schroeder
International Journal of Exercise Science: Conference Proceedings
Eccentric muscle contractions are often associated with exercise induced muscle damage (EIMD). EIMD can result in decreased force output, increased stiffness, and a loss in muscle function leading to decreased performance. Two of the many proposed treatments of EIMD are intermittent pneumatic compression (IPC) and blood flow restriction (BFR). BFR relies on occlusion and reintroduction of blood. IPC acts as an air-pressure massage, acting on a specific part of the limb, releasing, and re-inflating up the limb. PURPOSE: The purpose of this study is to determine whether BFR or pneumatic compression could minimize the effect of EIMD on muscle …

Reduced estrogen action is associated with obesity and insulin resistance in both males and females. However, the tissues and cell-specific targets essential for estrogen-mediated effects on metabolism remain inadequately understood. We have previously shown that muscle-specific estrogen-recpeptor alpha (ERa) knockout reduces metabolism and insulin sensitivity and blunts adaptations to exercise training. PURPOSE: The purpose of this study was to investigate the role of skeletal muscle ERa overexpression on whole-body metabolism, exercise capacity, and mitochondrial function. METHODS: A tamoxifen-inducible and muscle-specific ERa overexpression model (mERaOE) was generated in male mice. Body weight was tracked and a glucose …

The Age Of Initial Pointe Training Has A Weak Positive Correlation With Menarche In Female Pre-Professional Ballet Dancers, Jenna M. Dodson, Annie Smedley, Adrienne Henderson, Shayla Bott, Brenda Critchfield, A. Wayne Johnson
International Journal of Exercise Science: Conference Proceedings
In the ballet community, there is significant pressure to start intensive and frequent training at a young age. For example, serious professional students often move away from home as teenagers to train at a ballet boarding school full-time. The sense of urgency in training stems from the relatively short careers of professional ballet dancers and the tendency of ballet companies to replace dancers quickly as they age or get injured. Specialized training so early in adolescence can lead to overuse injuries, psychological stress, and regret later in life. PURPOSE: We studied the impact of intense training (defined as start …

"Cued At First Sight": Evaluating The Influence Of Depth On Gaze Cues, Priscilla Jussicha, Malissa Hildreth, Tamara Rodriguez, Morgan Martin, Justin Castillo, April Karlinsky
International Journal of Exercise Science: Conference Proceedings
When an individual provides a social cue, such as pointing or looking towards the left or right, an observer’s attention can involuntarily be drawn towards the cued location. Evidence for this social cueing effect comes from observers’ shorter reaction times (RTs) for targets at cued locations than at non-cued locations. However, it remains unknown whether observers are also sensitive to the depth of such social cues (in addition to the side of space indicated). Spatial depth refers to whether an area is relatively “near” or “far” from the observer. PURPOSE: The purpose of the current study was to determine whether …

Investigation Into Chin-Force Of Violinists, Ciya Clyde, Miles Mercer, Julia Freedman Silvernail
International Journal of Exercise Science: Conference Proceedings
Pain and discomfort have become a routine part of life for many orchestral musicians. Violinists in particular experience high number of injuries in their upper body, including the neck, shoulders, and arms. Force applied to the instrument at the chin provides the stabilization of the instrument required for performance but may contribute to these injuries. Due to the scarcity of research on musicians' physical health, it is challenging to determine the sources of musculoskeletal injuries in violinists. Nonetheless, examining the force applied at the chin could serve as a valuable starting point for investigation. PURPOSE: To investigate how chin-force is …

Differences In Joint Kinematics And Electromyography Activity Among The Conventional, Block, And Deficit Deadlifts, Christian R. Rogacion, Evan E. Schick, Joshua A. Cotter, Kevin Valenzuela
International Journal of Exercise Science: Conference Proceedings
The conventional deadlift (CDL) is a commonly used lower-body exercise that utilizes the legs, hips, back, and trunk muscles. The block deadlift (BDL) and the deficit deadlift (DDL) are two variations that alter the starting position and height of a deadlift, however, there is a lack of literature that examines both. PURPOSE: To quantify and compare joint kinematics and peak muscle activation differences between a CDL, BDL, and DDL. METHODS: Twenty total resistance-trained male and female participants (25.1 ± 3.6 yrs old, 81.0 ± 15.2 kg) performed a one-repetition maximum (1RM) in the CDL on day one. At …

The Influence Of Anticipation On Landing Error Scoring System Performance, Luis J. Valadez, Dominick J. Cece-Sherley, Marisol Valenzuela, Monica X. Cortes, Warren O. Forbes
International Journal of Exercise Science: Conference Proceedings
The Landing Error Score System (LESS) is a field assessment tool that can help identify biomechanics during a drop jump task that predispose an athlete to an increased risk of non-contact anterior cruciate ligament injury. While the LESS has shown to be valid and reliable, the pre-planned, anticipatory nature of the drop jump task during the LESS is not indicative of the movement strategies present in many sport settings. PURPOSE: The purpose of this study was to assess the influence of anticipation on landing error scoring system performance. METHODS: Twenty-two individuals participated in this study. Anticipated jumping trials consisted of …

Comparing Vascular Measures In Active And Inactive Females With Anterior Or Lateral T-Wave Inversions, Natalya Tasevski, Brianna Wheelock, Deborah L. Feairheller
International Journal of Exercise Science: Conference Proceedings
The presence of T-wave inversions in anterior or lateral leads on an electrocardiogram (ECG) can indicate a range of conditions, from benign to serious, such as myocardial ischemia. While ECG is not a routine screening tool for athletes, and T-wave inversions in anterior or lateral leads are not typically used as the primary diagnostic tool, integrating this with noninvasive vascular health measures like Augmentation Index (Alx@75) and Pulse Wave Velocity (PWV) could provide valuable insights. Both Alx@75 and PWV are measures of arterial stiffness and thus related to cardiovascular risk. Cardiac screening in active and athletic females is under-researched, so …

Speed Has No Correlation To Muscle Volume Of Hip Flexors And Tibialis Anterior Muscles In Division L Football Athletes, Isaiah B. Guymon, Malorie Wilwand, Steven P. Allen, B. Brett Mortensen, Aaron W. Johnson
International Journal of Exercise Science: Conference Proceedings
In American football (AF) a desirable trait is sprint speed that leads to success such as increased touchdowns, yards gained, and number of sacks. Researchers suggest training programs can improve an athletes’ sprint speed. Considering the swing to stance phases, the hip flexors (HF) and tibialis anterior (TA) may impact an athletes’ speed. The HF initiates the swing phase, while the TA muscle dorsiflexes the foot allowing the toes to clear the ground. PURPOSE: To determine if there is a correlation between collegiate football athlete's speed and the muscle volume (MV) of HF and TA muscles. METHODS: This study …
Females Who Have Undergone Acl Reconstruction Exhibit Altered Patellofemoral Joint Alignment And Reduced Contact: Implications For Early Onset Osteoarthritis, Thomas Demirjian, Olivia Tu, Gillian Northrup, Christopher Powers
Females Who Have Undergone Acl Reconstruction Exhibit Altered Patellofemoral Joint Alignment And Reduced Contact: Implications For Early Onset Osteoarthritis, Thomas Demirjian, Olivia Tu, Gillian Northrup, Christopher Powers
International Journal of Exercise Science: Conference Proceedings
Reconstruction is the gold standard treatment for those who have experienced a tear of the anterior cruciate ligament. Despite advancements in surgical technique and rehabilitation, a negative consequence of anterior ligament reconstruction (ACLr) is early onset osteoarthritis of the tibiofemoral joint and patellofemoral joint (PFJ). There is evidence that altered patella alignment may be contributory to early onset patellofemoral joint osteoarthritis. A negative consequence of patella malalignment is that contact between the patella and trochlea could be reduced, thereby exposing the joint to elevated stress (force per unit area). PURPOSE: The purpose of the current study was two-fold: 1) …

Determining Model Fit For Eccentric Hamstrings Strength: A Bayesian Approach, Lee J Hinkle, James D. Mead, Carson Bates, Aaron W. Johnson
International Journal of Exercise Science: Conference Proceedings
The Bayesian paradigm holds that previous knowledge or expertise (“prior”) and data-driven measurements (“likelihoods”) can produce an outcome (“posterior”) which can, in turn, be used as the prior in a new iteration of analysis and learning. In a wider project, we are undertaking to measure hamstrings strength, physical activity level, and ultrasound (US) and MRI characteristics of more than 200 participants ages 18+. PURPOSE: Here we aim to develop a model that will predict eccentric hamstrings strength as measured by Nordbord based on variables available in both surveys (IPAQ) and US for use as a starting point for our …
Measuring Fatigue After Singles Pickleball Tournament Play, Margaret J. Falknor, Steven Kim, James Annesi, George Beckham, Eric Martin
Measuring Fatigue After Singles Pickleball Tournament Play, Margaret J. Falknor, Steven Kim, James Annesi, George Beckham, Eric Martin
International Journal of Exercise Science: Conference Proceedings
Previously, we measured fatigue from one doubles pickleball match, multiple recreational doubles pickleball matches, and a nine-game doubles pickleball tournament. We found no evidence of neuromuscular fatigue in any of these scenarios. Therefore, doubles pickleball play may not be fatiguing enough to decrease jump performance. Singles pickleball matches may be more fatiguing than doubles play, because players must cover the court and return the ball without a partner. PURPOSE: Our goal was to determine if singles pickleball play would induce neuromuscular fatigue. METHODS: We included healthy adult pickleball players that had no lower body injuries within the past …

Downhill Dilemma: Analyzing Joint Force On Variable Speed And Gradient, Ulises Hernandez, Ezrie Pace, Kaeley Loader, Nathan Ramirez, Megan Nielsen, Michael Bohne
International Journal of Exercise Science: Conference Proceedings
Movement on declined slopes poses unique mechanical stresses when compared to level surfaces. Both downhill (DH) running and walking have seen large amounts of load force absorption on the knee (French 2018; Abe et.al., 2011) with some forces possibly being distributed to the hip and ankle joints. Though research is limited about lower extremity joint kinematics across all three joints. PURPOSE: To better understand the joint forces placed on the hip, knee, and ankle with variable speed and decline gradient METHODS: Nine participants (5 male and 4 female; Age = 24.09 ± 2.81 yrs; Weight = 75.12 ± 13.67 kg; …

Influence Of Region Of Interest Size On Vastus Lateralis Shear Wave Velocity In Individuals With Anterior Cruciate Ligament Reconstruction, Jonathan L. Cardon, Brian W. Noehren, Mckenzie White
International Journal of Exercise Science: Conference Proceedings
PURPOSE: Shear wave elastography (SWE) is an emerging tool for estimating passive muscle stiffness via shear wave velocity (SWV). However, the lack of standardized collection and processing methods limits its clinical utility. One key factor in SWV analyses is the region of interest (ROI), which varies in size across the literature. Individuals post-anterior cruciate ligament reconstruction (ACLR) show changes in muscle quality, making it plausible that ROI size could influence SWE measurements in this population. METHODS: Twenty individuals post-ACLR participated (11M/9F, age = 19 ± 2 years, time since surgery = 5 ± 5 months, body mass index = …
