A Movement Tool Kit for the Divergent and Convergent CPS Guidelines:

Instruction Cards and Activity Floor Mats

Movement is as natural to humans as breathing is, and, yet, passivity starts early in schools. We are taught to sit still and in silence for long periods of time. By the time we reach adulthood and enter the workforce, we have almost forgotten our sense of embodiment. This lack of movement is counter-productive, not only to learning but to the development of creativity as well. For this project, I designed a tool to recapture the joy and playfulness of movement. Furthermore, the …

Insulin Resistance And Muscle Insulin Receptor Substrate-1 Serine Hyperphosphorylation, Charles A. Stuart, Mary E. A. Howell, Brian M. Cartwright, Melanie P. Mccurry, Michelle L. Lee, Michael W. Ramsey, Michael H. Stone

ETSU Faculty Works

Insulin resistance in metabolic syndrome subjects is profound in spite of muscle insulin receptor and insulin-responsive glucose transporter (GLUT4) expression being nearly normal. Insulin receptor tyrosine kinase phosphorylation of insulin receptor substrate-1 (IRS-1) at Tyr896 is a necessary step in insulin stimulation of translocation of GLUT4 to the cell surface. Serine phosphorylation of IRS-1 by some kinases diminishes insulin action in mice. We evaluated the phosphorylation status of muscle IRS-1 in 33 subjects with the metabolic syndrome and seventeen lean controls. Each underwent euglycemic insulin clamps and a thigh muscle biopsy before and after 8 weeks of either strength or …

The Effect Of A Controlled Frequency Breath Holding Training Program On Running Economy Among Elite College Swimmers., Patrick Sims 1988-

Electronic Theses and Dissertations

Running economy (RE) is the amount of oxygen consumed while running at a submaximal intensity. Along with aerobic capacity (VO2max), RE is an important predictor of running performance. Little research has investigated changes in RE with restricted breathing training [i.e. controlled breath-holding (CFB)] during exercise. RE may improve ~6% amongst a novice swimming cohort through CFB training, but this has not been established in elite swimmers. The purpose was to further establish that CFB training (16 sessions of 12 x 50-m with ~15 seconds rest between each 50-m, using only ~2 breaths per 50-m) can improve RE in 25 elite …

The Reduction Of Metabolic Cost While Using Handrail Support During Inclined Treadmill Walking Is Dependent On The Handrail-Use Instruction, Cory Hofmann, Connor Dougherty, Hagop Abkarian, Michele Fox, Paul Juris

International Journal of Exercise Science

International Journal of Exercise Science 7(4) : 339-345, 2014. Inclined treadmill walking is a commonly performed activity to increase cardiovascular health. Handrail support on a treadmill provides an individual the opportunity to change their posture with respect to the walking surface. Differences in metabolic cost during inclined walking due to postural changes with handrail use are unknown. To test the hypothesis that metabolic cost will differ depending on how handrail support is used, respiratory gas analysis was performed during inclined walking in 13 healthy subjects. Energy expenditure was quantified while each subject walked in four conditions: 5% incline unsupported, 10% …

Lactate Threshold Comparison In Anaerobic Vs. Aerobic Athletes And Untrained Subjects, Matt Green, Jared Hornsby, Robert Pritchett, Kelley Pritchett

International Journal of Exercise Science

International Journal of Exercise Science 7(4) : 329-338, 2014. This study compared VO₂ max, lactate threshold (LT) and VO₂ at LT (VO_2LT) among aerobic athletes (ARA) (n=10), anaerobic athletes (ANA) (n=9) and untrained participants (UTS) (n=7). From a treadmill test to exhaustion, VO₂ max and LT (4 mmol·L^-1 blood lactate concentration) were assessed. Analysis of variance showed VO₂ max (ml·kg^-1·min^-1) was significantly greater for ARA (67.6 ± 9.4) than ANA (53.4 ± 6.4) and UTS (44.9 + 6.9), with ANA significantly greater than UTS. LT for ARA (82.9 + …

International Journal of Exercise Science

International Journal of Exercise Science 7(4) : 318-328, 2014. Team intercollegiate athletic competition is associated with an increase in salivary cortisol (C) and testosterone (T) in men and women. The present study was designed to determine the hormonal effects of warm-up and racing in cross country runners – a sport that has both individual and team components. Members of the Emory University men’s and women’s varsity cross country teams gave saliva samples before warm-up, after warm-up, and immediately after the finish of each of two intercollegiate invitational meets held one year apart in the same setting (2010, N = 10 …

Vo2 Reserve Vs. Heart Rate Reserve During Moderate Intensity Treadmill Exercise, Tanner J. Solheim, Brad G. Keller, Charles J. Fountaine

International Journal of Exercise Science

International Journal of Exercise Science 7(4) : 311-317, 2014. ­VO₂ and heart rate (HR) are widely used when determining appropriate training intensities for clinical, healthy, and athletic populations. It has been shown that if the % reserve (%R) is used, rather than % of max, HR and VO₂ can be used interchangeably to accurately prescribe exercise intensities. Thus, heart rate reserve (HRR) can be prescribed if VO₂ reserve (VO₂R) is known. Therefore, the purpose of this study was to compare VO₂ R and HRR during moderate intensity exercise (50%R). Physically active college students …

The relationship between CODS in the frontal plane and power, strength, and reactive strength is largely unstudied. Twenty-three male college students participated in this study. The study used a Pearson’s product-moment correlation to measure the relationship between CODS, power, strength, and reactive strength. A lateral shuffle test was used as the measure of CODS. A lateral hop for distance was used as the measure of power in the frontal plane. A countermovement vertical jump test was used as the …

Sleep Patterns In Collegiate Dancers, Beth Nicks, Jacque Price

e-Research: A Journal of Undergraduate Work

As college dance majors, the investigators have witnessed firsthand the effects that sleep and the lack thereof can have on the performance quality of University level dancing. It has been shown that lack of sleep can compromise nearly every physiological process such as memory, coordination, metabolism, and new learning (Wozny 2008). Studies on disruptions of the human circadian rhythms have shown that athletes involved in endeavors where sleep is restricted or totally deprived have severe consequences on behavior and performance. (Edwards 2007). However, the environment of college dance programs is different than athletics due to there being no off season. …
