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

ABSTRACT
Hip and ankle mobility are important variables in ball velocity and pitching performance. Possible indices in hip mobility are passivehip internal rotation (IR) and external rotation (ER). A contributor of ankle mobility is passive ankle dorsi-flexion (PAD). This study examines the relationship of selected indices in hip and ankle mobility for collegiate baseball pitchers with the athlete’s respective coaches’ rating of pitching performance …
Relationships Between Anthropometric And Performance Variables In Youth: Predictors Of Lower-Body Vertical Jump Peak Power, Alexander S. Drusch, Elias M. Carrillo, Jacob Adam Mota, Kendra D. Olinghouse, Matt S. Stock, Marc Lochbaum, Brennan J. Thompson
Relationships Between Anthropometric And Performance Variables In Youth: Predictors Of Lower-Body Vertical Jump Peak Power, Alexander S. Drusch, Elias M. Carrillo, Jacob Adam Mota, Kendra D. Olinghouse, Matt S. Stock, Marc Lochbaum, Brennan J. Thompson

ABSTRACT
Anthropometric and physical performance measurements are commonly used for identifying specific physical traits in youth. Laboratory-based tests (e.g., linear velocity transducers), while accurate, provide practical limitations due to high costs and technical necessities. 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 …

Effect Of Combined Aerobic And Resistance Training On Hpa Axis Reactivity In Hiv+ Women Undergoing Treatment For Substance Abuse, Hui-Ying Luk, Jakob L. Vingren, Anthony A. Duplanty, Alex Fernandez, James Miller, David W. Hill
International Journal of Exercise Science: Conference Proceedings
Substance abuse and infection with human immunodeficiency virus (HIV) are chronic stressors that affect hypothalamic-pituitary-adrenal (HPA) axis function. The purpose of this study was to investigate the effect of combined aerobic and resistance training on HPA axis reactivity in women with HIV undergoing treatment for substance abuse. Sixteen women (mean ± SD; 41 ± 9 years, 164 ± 6 cm, 78.1 ± 17.1 kg, 36 ± 10 % body fat) infected with HIV and enrolled in an intensive 60-day in-patient substance addiction/abuse treatment program were recruited shortly after admission to the treatment facility. Participants were assigned to one of two …

Hippotherapy utilizes the rhythmic movement of the horse to improve functional abilities and quality of life of individuals with neurological impairments. Little is known regarding the changes in body segment kinematics and cardiovascular responses of the rider due to the therapy. A change in the magnitude of pelvic displacement (PD) may allow those who use the therapy to more easily perform activities of daily living. Also, reduced cardiovascular stress to similar physical activities may be an important, but overlooked, therapeutic benefit of hippotherapy. The purpose of this study was to characterize PD and cardiorespiratory (CR) responses to simulated horseback riding …
