Are Responses To Submaximal Exercise Less Reproducible In Females Vs Males Due To The Menstrual Cycle?, Grace Loveless, Hadley Peay, Jayson Gifford, Jessica Linde
Are Responses To Submaximal Exercise Less Reproducible In Females Vs Males Due To The Menstrual Cycle?, Grace Loveless, Hadley Peay, Jayson Gifford, Jessica Linde
International Journal of Exercise Science: Conference Proceedings
Exercise-science research often excludes young eumenorrheic females due to the presence of a menstrual cycle (MC) and lack of knowledge on how much variability the MC adds to the physiological responses to exercise. PURPOSE: To determine if the metabolic response to submaximal exercise is less reproducible in females with a menstrual cycle compared to males. We hypothesized females would exhibit greater variability in the metabolic response to submaximal-intensity exercise across the MC than males across a similar timespan. METHODS: Eumenorrheic, endurance-trained females (n=10, age=24.1 ± 5.59) performed two 5-minute bouts of constant-load, moderate-intensity cycling at three time points across the …
Body Mass & Muscle Weight Following Volumetric Muscle Loss Injuries, Kyndal Jones, Jj Payne, Matt Mangus, Jake Sorensen
Body Mass & Muscle Weight Following Volumetric Muscle Loss Injuries, Kyndal Jones, Jj Payne, Matt Mangus, Jake Sorensen
International Journal of Exercise Science: Conference Proceedings
Volumetric muscle loss (VML) is the traumatic or surgical loss of a significant amount of skeletal muscle, resulting in decreased function and regenerative abilities. Despite the decrease in function, when one muscle is injured or removed, there is typically a compensatory response in the surrounding muscles that promote hypertrophic adaptations. PURPOSE: The purpose of this study was to observe how surgery impacts body mass and the weight of certain muscle groups 6 weeks after a VML injury to the tibialis anterior (TA) muscle, with particular interest in determining if a hypertrophy response occurs in surrounding muscle groups. METHODS: …

No Side Difference Between Achilles Tendon Characteristics In Female Division One Collegiate Gymnasts Post Exercise: Preliminary Study, Phillip Hartog, Lee J. Hinkle, Gabe Davidson, Bryson T. Schaugaard, Melody Anderson, Aaron W. Johnson
No Side Difference Between Achilles Tendon Characteristics In Female Division One Collegiate Gymnasts Post Exercise: Preliminary Study, Phillip Hartog, Lee J. Hinkle, Gabe Davidson, Bryson T. Schaugaard, Melody Anderson, Aaron W. Johnson
International Journal of Exercise Science: Conference Proceedings
Female gymnasts have a high rate of injury due to the repetitive nature and high forces of the sport. Repetition of movements is necessary to improve confidence and perfect execution. However, such repetition may also lead to overloading the Achilles tendon (AT) and increases potential of tendinopathy. Gymnasts generally perform the same skills repetitively using a preferred leg, e.g. always jumping off the right leg entering the vault. PURPOSE: To determine the differences in characteristics of NCAA Division I female gymnasts’ AT between preferred leg (PL) and non-preferred leg (NPL). We hypothesize differences in cross-sectional area (CSA), thickness, and …
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
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 …

The Effect Of Percussive Massage On Skeletal Muscle Atrophy During Limb Immobilization, Austin D. Cox, Robert Hyldahl, David Kofoed, James Bartling
International Journal of Exercise Science: Conference Proceedings
Muscle disuse and subsequent muscle loss are common consequences of injury. Various forms of skeletal muscle mechanical stimulation have been found to be helpful in preserving muscle mass and function during disuse. Recently, percussive massage devices have become popular devices for the application of mechanical stimulation. PURPOSE: This study investigated the potential benefits of percussive massage to mitigate muscle loss during a period of limb immobilization. METHODS: Seventeen healthy young adults (ages 18-35) underwent a 10-day period of immoblization of the right leg. Participants were randomly assigned to either a percussive massage group (n=9), receiving twice-daily 20-minute sessions on …
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
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 = …

International Journal of Exercise Science: Conference Proceedings
Endothelial dysfunction is characterized by the unbalance between vasodilatory and vasoconstrictor mechanisms. Furthermore, this is recognized as the initial step to developing cardiovascular disease. Exercise plays an important role in both cardiac rehabilitation and cardiovascular risk prevention. However, some new exercise modalities, such as high-intensity interval training (HIIT), are becoming more popular, and limited information about their effect on the endothelium is available. PURPOSE: to determine what volume of HIIT will improve endothelial function than continuous moderate exercise intensity. METHODS: Six young apparently healthy subjects were recruited for seven laboratory visits. The first visit included a graded exercise test, in …

Exercise Pressor Response In Hispanic Adults With Family History Of Hypertension, Ashlesha D. Dalve, Justo Perez Iii, Ruby A. Nyarko, Jasdeep Kaur
International Journal of Exercise Science: Conference Proceedings
Family history of hypertension (FHH), being an unmodifiable risk factor, increases probability of developing hypertension and other cardiovascular diseases. The prevalence of hypertension in Hispanic/Latino (H/La) males is 50.3%, while it is 48.9% in non-Hispanic white (NHW) males and 57.5% in non-Hispanic black (NHB) males. Among adolescents aged 8 to 17, H/La youth has the highest incidence of hypertension as compared to all other races. It is evident that young normotensive adults with positive family history of hypertension (+FHH) exhibit exaggerated exercise pressor response. Additionally, a higher sympathetic activity to cold pressor test (CPT) was found in normotensive NHB adults …

The Influence Of High-Intensity Interval Exercise On Vitamin-D Concentrations In Healthy Individuals, Leroy K. Bolden, Tomas Chapman-Lopez, Ricardo Torres, Jeffery Heileson, Meena Meiyyappan, Jeff S. Forsse
International Journal of Exercise Science: Conference Proceedings
Vitamin D (VD) deficiency is one of the most common deficiencies in the world due to various factors (e.g., lack of sun exposure, dietary considerations). Currently the utilization of exercise may act as an intervention for VD deficiencies to promote increases in VD concentrations in healthy populations. This could largely be due to the loss of calcium from aerobic exercise (AE), leading to a hormonal response [(e.g., parathyroid hormone (PTH)] and the activation of cytochrome’s (e.g., CYP2R1, CYP27B1) responsible for the regulation of VD. Thus, AE may serve as an intervention to promote VD synthesis due to the impacted biological …

Firefighters Versus Law Enforcement Officers: A Comparison Of Cardiovascular Disease Risk, Bethany C. Guerra, Hunter Martaindale, Steven E. Martin, Lisa C. Colvin, Drew E. Gonzalez, Matthew J. Mcallister
International Journal of Exercise Science: Conference Proceedings
Firefighters (FF) and law enforcement officers (LEO) have heightened cardiovascular disease (CVD) risk due to the stressful nature of their occupations. Data suggest that 45% of on-duty FF fatalities are related to CVD, while LEO have a 1.7 times higher CVD prevalence compared to the general public. To our knowledge, studies comparing FF to LEO, in terms of CVD risk factors, have not been published. This information is necessary to better understand differences in occupational disease risk, as well as to help bridge the gap between stress and CVD markers. PURPOSE: To compare CVD risk biomarkers, fitness, and body …

Paroxysmal Atrial Fibrillation In A Life-Long Endurance Athlete: A Descriptive Case Study, Timothy Curry, Scott N. Drum
International Journal of Exercise Science: Conference Proceedings
The diagnosis of atrial fibrillation (AF) in lifelong endurance athletes occurs at a greater incidence over a lifetime vs the undertrained, general population. In fact, the more intense an aerobic-oriented person trains or races and over a greater amount of time, the higher the diagnosis of general cardiac arrhythmias. PURPOSE: Therefore, the primary aim was to observe the cumulative effects of life-long endurance training (since the age of 10-yrs old) and the yearly occurrences of paroxysmal AF (PAF) in an otherwise healthy, 53-yr-old male. METHODS: The complete health history of a 53-yr-old male (ht: 1.83 m, wt: 72.7 kg, …

International Journal of Exercise Science: Conference Proceedings
Pickleball is making a name for itself as one of the fastest growing sports in the United States. According to the Association of Pickleball Professionals (APP), 14% of Americans 18 years and over (~36.5 million people) played pickleball at least once in 12 months. With almost half of the total players planning to play more often in the upcoming months, pickleball is certain to continue its ascension. It is unclear if paying intensity can be gauged accurately and reliably with heart rate (HR) measurements from biceps-band monitors. PURPOSE: This study aimed to determine the validity and reliability of the Polar …

International Journal of Exercise Science: Conference Proceedings
Females are more likely to suffer Achilles tendon injury that consequently leads to more complications including pain or tendon rupture, and experiencing fewer benefits from therapeutic interventions. There is a lack of knowledge on how estrogen, which may limit collagen synthesis, can affect tendon health and growth. PURPOSE: The objective of this study is to examine the relationship between menstruation duration and cross-sectional area (CSA) of the Achilles tendon over a 5-month period of intensive dance training. We hypothesize the female dancers who reported a menstruation duration of 1-3 days will have the smallest average tendon CSA in comparison …

International Journal of Exercise Science: Conference Proceedings
bioDensity training is a novel type of resistance exercise, which includes four basic isometric exercises in a subsequent fashion: chest press, leg press, core pull, and vertical lift. Although it’s primarily targeted on bone strength, a previous study showed that it improved HbA1C, fasting glucose, HDL, LDL and total cholesterol in elderly patients with Type 2 diabetes (Zheng et al. 2019). To date, the research on bioDensity training is limited, and its effects on a healthy population are unknown. PURPOSE: We are looking to examine the effects of 12-week bioDensity training on lipid profiles in young women. METHODS: …

Diaphragm Force And Mitochondrial Function Ex Vivo Following Gsnor Inhibition In Vivo Preceding Mechanical Ventilation, Simon P. Pierce, Daniel T. Cannon, Leonardo Nogueira
International Journal of Exercise Science: Conference Proceedings
During mechanical ventilation (MV), force developed by the diaphragm is decreased over time much faster than locomotor muscles. This is known as ventilator-induced diaphragm dysfunction (VIDD), and VIDD may be accelerated by intramyofiber oxidative stress. An important free radical used for the treatment of acute respiratory distress syndrome (ARDS) is nitric oxide (NO) which can diffuse to diaphragm myofibers during treatment. However, little is known whether NO or NO by-products such as S-nitrosothiols (RSNO), can accelerate or prevent VIDD. PURPOSE: To investigate whether inhibiting S-nitrosoglutathione reductase (GSNORi) during MV could affect ex vivo diaphragm force and mitochondrial respiration. METHODS …

Single-Leg Resistance Exercise Training In Mice Leads To A Fast Increase In In Vivo Torque Of Anterior Crural Muscles, Lloyd K.T. Marshall, Dylan M. Kasper, Leonardo Nogueira Phd
International Journal of Exercise Science: Conference Proceedings
Resistance exercise is known to produce muscle hypertrophy. However, little is known about the role of muscle satellite cells in generating new myofibers or in incorporating satellite cells to live myofibers during exercise training. PURPOSE: To investigate whether single-leg resistance exercise training can activate the incorporation of muscle satellite cells in mice. METHODS: Transgenic male mice (12 weeks old) that express Td-Tomato fluorescent protein in Pax7+ (i.e., satellite cells) cells (Pax7CreER-Ai9) were treated with tamoxifen (2 mg in corn oil, i.p.) once a day for 5 days. Three days later, mice were single-leg exercise trained (i.e stimulation of …

Timing Of Nordic Hamstring Exercise In Youth Soccer Players To Reduce Injury, Brooke Butterick, Carson Gantzer, Jason Siegler
International Journal of Exercise Science: Conference Proceedings
The Nordic hamstring exercise (NHE) has been demonstrated to be an effective strength exercise to help mitigate the risk of hamstring injury in soccer players. It is a component of the FIFA 11+ grassroots injury prevention program, which is a series of warm-up exercises designed to be administered in large groups and at minimal cost. Recent evidence in adults suggests that the acute fatigue associated with the NHE may increase the risk of injury during training, causing some to suggest moving the NHE until the end of training. PURPOSE: To determine whether this same level of fatigue persists in young …

Resistance Exercise, Muscle Strength, Physical Function And Quality Of Life In Head And Neck Cancer Patients Undergoing Chemoradiation, Ezrie Pace, Kathryn Dispennette, Dukagjin Blakaj, Zachary Chaplow, Brian Focht
International Journal of Exercise Science: Conference Proceedings
Chemoradiation therapy (CRT) is the standard of care treatment for Head and Neck Cancer (HNCa) patients. Despite its established therapeutic efficacy, adverse effects accompanying CRT result in clinically-meaningful declines in muscle strength, physical function and quality of life (QOL). The adverse effects observed during CRT place HNCa patients at heightened risk for functional decline, mortality, and morbidity. Accordingly, there is a pressing need to evaluate the utility of supportive care interventions, such as resistance exercise (RE), to attenuate the deleterious effects observed during CRT. PURPOSE: Determine the utility of implementing a group-mediated cognitive behavioral (GMCB) RE intervention in the treatment …
