Comparison Of Landing Variables Between Countermovement Jump Landings And Drop Vertical Jump Landings From Equal Heights, Mia Hite, Katie N. Harris, John Robert Harry

International Journal of Exercise Science: Conference Proceedings

The countermovement jump (CMJ) and drop vertical jump (DVJ) are often used as a measurement of physical ability or performance potential, while analysis of landing can provide crucial information regarding injury risk. In theory, similar landing strategies should be employed when CMJ jump height and DVJ drop height are controlled, yet we know of no studies have investigated this possibility. PURPOSE: to examine and compare landing characteristics between CMJ and DVJ when flight height is controlled. METHODS: Forty (20 males; 20 females; 22.5 ± 4.3 years, 1.7 ± 0.1 m, 73.2 ± 13.3 kg) recreationally active individuals performed …

Selective Inhibition Of Ribosomal Biogenesis Over Cap-Dependent Translation By Rapamycin In L6 Myotubes, Selina Uranga, James D. Fluckey

International Journal of Exercise Science: Conference Proceedings

The mechanistic target of rapamycin, or mTOR, lies at the center of skeletal muscle anabolic regulation. The mTOR kinase has at least two complexes that aide in carrying out responses to anabolic signals. Complex 1 (mTORC1) activation leads to cap-dependent translation and ribosomal biogenesis via phosphorylation of its two downstream targets 4EBP1 and P70S6K respectively. mTORC1 is inhibited by rapamycin while mTORC2 is not; however, cap-dependent translation via mTORC1 may still occur under rapamycin inhibition. PURPOSE: To identify timing and mechanistic pathway by which selective skeletal muscle anabolism continues in the presence of rapamycin inhibition. METHODS: Murine L6 …

Pressor And Sympathetic Responses To Graded Skeletal Muscle Metaboreflex Activation In Females With Relapsing-Remitting Multiple Sclerosis, Claire E. Trotter, Benjamin E. Young, Caitlin P. Jarrard, Scott A. Smith, Paul J. Fadel, Mu Huang, Scott L. Davis

International Journal of Exercise Science: Conference Proceedings

Multiple sclerosis (MS) is a progressive disease characterized by demyelination in the central nervous system which disproportionately impacts females. Previous studies suggest MS-related exercise intolerance may be due to abnormal control of arterial blood pressure (BP) via the skeletal muscle metaboreflex. However, few studies have been performed and equivocal results reported. Discontinuity in prior data may be due to limited perturbation of metaboreflex activation using only low and moderate intensity exercise. PURPOSE: The purpose of this investigation was to test the hypothesis that females with MS have blunted BP and sympathetic responses to graded static handgrip (HG) exercise and isolated …

Thirst Sensation Does Not Effect Reaction Time But Decreses Mood In Men, Alan Ky, Hui-Ying Luk, Jarrod Blinch, Yasuki Sekiguchi

International Journal of Exercise Science: Conference Proceedings

Exercise in hot environments results in dehydration accompanied by thirst sensation, a vital signal for fluid homeostasis. While cognitive performance and mood have been studied with exercise in hot environments and in dehydration states, no studies have investigated the effect of inducing thirst on cognitive performance and mood. PURPOSE: To investigate the effect of inducing thirst on cognitive performance and mood. METHODS: Twelve recreationally active men (mean±SE age: 29±3.6 years; body mass: 74.7±2.3 kg; height, 179.4±2.0 cm; maximal oxygen consumption [VO_2max]: 49.8±1.9 ml·kg⁻¹·min⁻¹) performed 90 mins of cycling at 55% VO_{2max …}

PURPOSE: To assess and quantify the effect of different HA methods on the magnitude of performance and physiological adaptations in endurance trained athletes METHODS: A literature search was conducted in PubMed, SPORTDiscus, Scopus, and Cochrane-Library, with data from 23 studies gathered for …

Autophagy Is Required For Mtor-Mediated Anabolism In Skeletal Muscle, Patrick Ryan, Sean Stanelle, Megan Humphries, Colleen L. O'Reilly, Selina Uranga, Jessica M. Cardin, James D. Fluckey

International Journal of Exercise Science: Conference Proceedings

PURPOSE: While much has been discovered about the role autophagy in protein degradation, recent evidence suggests that autophagy is required for muscular adaptations to exercise, hinting at a hitherto unknown cross-talk between autophagic proteolysis and muscle protein anabolism. Here, we set out to further elucidate the metabolic mechanisms by which autophagy may influence protein anabolism. METHODS: L6 myoblasts received either electrical pulse stimulation (EPS) to induce muscle contraction or were unstimulated to serve as controls, and were then treated with an inhibitor of the ATG4 enzyme which catalyzes the initial step of autophagy NSC185058 (NSC, 100 μM) or DMSO as …

Test-Retest Reliability Of Automatic And Manual Image Analyses Of Muscle Size, Carina M. Velasquez, Kealey J. Wohlgemuth, Mckenzie M. Hare, Malia N.M. Blue, Jacob A. Mota

International Journal of Exercise Science: Conference Proceedings

Brightness-mode (B-mode) ultrasound is a non-invasive imaging modality that has risen in popularity. In research settings, B-mode ultrasound is often used to assess skeletal muscle size via the quantification of the anatomical cross-sectional area (ACSA). Typically, these images are analyzed by an experienced investigator using open-source software, though it is a time-consuming process that may introduce implicit bias into the analysis. Recently, a novel, automatic ultrasound image analysis tool has been developed which may reduce bias and increase the reliability of ultrasound ACSA image analysis. PURPOSE: The purpose of the project was to compare the test-retest reliability of manual …

Does The Analysis Of Separate Bands Of Echo Intensity Strengthen The Relationship To Muscle Function?, Kathryn Southall, Kealey J. Wohlgemuth, Mckenzie M. Hare, Jacob A. Mota

International Journal of Exercise Science: Conference Proceedings

Ultrasound echo intensity (EI) has been proposed as a method of assessing muscle quality through the use of non-invasive imaging. Traditionally, EI is assessed as the mean pixel brightness that ranges from 0-255 within an area of interest. However, it may be reasonable to consider that additional portions of the ultrasound EI signal (i.e., bands of signal) may provide novel insight to muscle function. The determination of which band of signal may be more related to a given functional outcome may increase the sensitivity of EI. Thus far, there is no research analyzing the association between EI bands and fatigue. …

The Effect Of Body Composition Methodology On Resulting Energy Availability Assessments, Madelin R. Siedler, Christian Rodriguez, Matthew T. Stratton, Patrick S. Harty, Dale Keith, Jacob Green, Jake Boykin, Sarah White, Abegale D. Williams, Gabrielle Dehaven, Grant M. Tinsley

International Journal of Exercise Science: Conference Proceedings

Energy availability (EA) is defined as the total daily energy available to an individual after accounting for that expended during exercise and standardized to fat-free mass (FFM). Generally, EA values less than 30 kcal/kg FFM/day are considered “low” and have been associated with deleterious effects on reproductive and hormonal health in females. However, it is unclear whether the method used to estimate FFM influences the resulting EA values to a degree that may affect interpretation and clinical decision-making. PURPOSE: To determine the effect of FFM values derived from various methods of body composition assessment on the resulting range and interpretation …

Reliability Of Differing Muscle Size And Quality Analysis Techniques, Mckenzie M. Hare, Kealey J. Wohlgemuth, Malia N.M. Blue, Jacob A. Mota

International Journal of Exercise Science: Conference Proceedings

Brightness-mode (B-mode) ultrasonography is a popular tool to examine anatomical cross-sectional area (ACSA) and echo intensity (EI). Muscle ACSA and EI provide valuable insight into muscle function due to their unique mechanisms which influence performance.
