Sensitivity Of Prescribing High-Intensity, Interval Training Using The Critical Power Concept, Robert W. Pettitt, Ashley M. Placek, Ida E. Clark, Nicholas A. Jamnick, Steven R. Murray

International Journal of Exercise Science

International Journal of Exercise Science 8(3): 202-212, 2015. The critical power (CP) concept enables the calculation of time to exhaustion (t_LIM) for a given power output above CP using the equation of t_LIM = W’/(power – CP), where W’ is the curvature constant, and CP is the asymptote for the power-t_LIM relationship. The CP concept offers great promise for prescribing high-intensity interval training (HIIT); however, knowledge on the concept’s sensitivity is lacking (i.e., how much of a difference in W’ expenditure is needed to evoke different metabolic responses). We tested if two …

International Journal of Exercise Science: Conference Proceedings

The severity of a concussion is determined by the magnitude of the force of impact and the symptoms expressed post-injury. The most current and widely used test to identify a concussion in college athletics is called the Immediate Post Concussion Assessment and Cognitive Testing (ImPACT). It is a computerized neurocognitive test battery that measures different cognitive abilities and compares baseline with post-injury results. In the current study we formulated a series of physical and psychological cognition tests that measure similar cognitive abilities as the ImPACT. The purpose of this study is to demonstrate that physical tests paired with neurocognitive tests …

The Effect Of Multiple Sclerosis On Carotid Baroreflex Control Of Heart Rate And Blood Pressure, Dustin R. Allen, Mu Huang, David M. Keller, Scott L. Davis

International Journal of Exercise Science: Conference Proceedings

Multiple sclerosis (MS) is marked by conduction abnormalities within the central nervous system that can lead to impaired blood pressure regulation. However, the impact of this disease on dynamic neural control—responsiveness and timing (i.e., latency)—of blood pressure has not been examined. Utilizing a variable neck chamber system, we tested the hypothesis that patients with MS (MS: n=4) exhibit an altered response following baroreflex perturbation compared to sex and age matched healthy controls (CON: n=4). At rest, 5-sec pulses of neck suction (NS; -60 Torr) and neck pressure (NP; +40 Torr) were applied to simulate carotid hypertension and hypotension, respectively. Mean …

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% …

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 Effect Of Angiotensin Converting Enzyme Genotype On Aerobic Capacity Following High Intensity Interval Training, Nicole Goddard, Matthew Baker, Tim Higgins, Christian Cobbold

International Journal of Exercise Science

International Journal of Exercise Science 7(3) : 250-259, 2014. Obesity increases the risk of developing type 2 diabetes mellitus (T2DM) and cardiovascular disease (CVD). Physical activity can reduce T2DM and CVD risk, and increase aerobic capacity, a significant predictor of all-cause mortality and morbidity. High intensity interval training (HIIT) produces similar improvements in aerobic capacity to continuous moderate exercise (CME). Different genotypes of angiotensin converting enzyme (ACE) have been implicated in improving aerobic capacity and therefore predicted health. This study investigated the effects of different ACE genotypes on the impact of 6 weeks of HIIT on aerobic capacity, and thus …

Thus, commonly used field tests may be useful alternatives for assessing fitness/performance characteristics of youth. The purpose of this study was to examine the relationships between anthropometric measures and lower-and upper-body power and strength measures; and to assess the predictive ability of these measures for lower-body vertical jump peak power (PP) output in youth. Thirty-nine pre-adolescent (mean±SD, range: age=7.8±1.7, 5-12 years) children volunteered to participate in …

Decrements Of Muscle Protein Synthesis With Unloading Are Not Due To Insufficient Concentrations Of Intramuscular Leucine, Shaik T. Ullah, Kevin Shimkus, Yasaman Shirazi-Fard, Camilo Pohlenz, Jacqueline Perticone, Del Gatlin, Harry Hogan, James Fluckey

International Journal of Exercise Science: Conference Proceedings

Skeletal muscle mass and strength play critical roles in quality of life, and significant muscle atrophy contributes to reduced function and can exacerbate some disease states. It is well-known that persistent reductions of mechanical loading in skeletal muscle result in degeneration. Generally, reductions of muscle protein synthesis are, at least in part, a major culprit with muscle loss under these conditions, and numerous countermeasures such as exercise and nutritional supplements, known to stimulate protein synthesis have been designed to maintain muscle mass under those conditions. Amino acid supplementation, particularly with branched-chain amino acids (BCAAs), has been suggested as a countermeasure …

Preliminary Data Regarding How Wheelchair Axle Position Effects The Energy Cost Of Assistants Pushing Wheelchairs Designed For Low-Resource Settings., Matthew K. Sturm, Josh Vanleer, Nathan Lowe, Karen Rispin

International Journal of Exercise Science: Conference Proceedings

A study at Letourneau University was performed to compare the energy cost of pushing wheelchairs with differing axle positions in relation to the occupant’s center of gravity (COG). In less-resourced areas of the world, powered wheelchairs are rarely feasible, requiring an assistant to push the chair. Often these assistants themselves are disabled, making any means of minimizing energy cost imperative. Research has indicated that as the rear axle comes closer to the COG, the energy cost of self-propelling the chair decreases. We hypothesized that able-bodied assistants pushing wheelchairs could provide valuable insight into the effect of axle position on energy …
