Validity And Reliability Of The Ymca Submaximal Cycle Test Using An Electrically Braked Ergometer, Justin Kidd

Senior Honors Projects, 2010-2019

Purpose: To test the effect of using an electrically braked ergometer on the validity and reliability of the YMCA submaximal cycle test.

Methods: 22 male and 13 female subjects ages 19 to 31 completed one maximal treadmill test and four submaximal cycle tests to measure and estimate VO_2max, respectively. The maximal tests involved recording heart rate and VO₂ during graded exercise until volitional fatigue; an actual max was verified when two out of the following criteria: respiratory Exchange Ratio > 1.1, VO₂ plateau (< 150 ml/min increase in VO₂ during final stage), and achievement of 90% age-predicted HR max (or completed a ...

Racial Comparisons In Police Officer Bench Press Strength Over 12.5 Years, Robert W. Boyce, Tyler K. Willett, Glenn R. Jones, Edward L. Boone

International Journal of Exercise Science

International Journal of Exercise Science 7(2) : 140-151, 2014. Strength, when considering gender and race, provides a basis for training, hiring, and retention for police officers. The purpose of this study is to identify muscular strength differences among racial groups from initial-recruit to in-service tests. Strength variables included bench press, bench press/lean mass and bench press/body mass. Scores were retrieved for the 1990 to 1995 recruit classes and were paired to the 2006 in-service fitness log. Sample included 309 officers: 30 females (13 black, 17 white) and 279 males (41 black, 238 white). Mean age of recruit was ...

Comparison Of The Ymca Cycle Sub-Maximal Vo2 Max Test To A Treadmill Vo2 Max Test, Jeremy G. Carter, Kelly A. Brooks, Joshua R. Sparks

International Journal of Exercise Science: Conference Proceedings

INTRODUCTION: An individual’s maximum capacity to extract, transport, and utilize oxygen is reflected by their VO2 max (10,22). Numerous physiological factors affect a person’s maximal oxygen consumption. A person’s VO2 max is dependent on their pulmonary, cardiovascular, and muscular systems, which depends on their ventilation-aeration efficiency, central and peripheral blood flow, and metabolism of their active muscles (13,17). The six factors that have the most influence on a person’s maximal aerobic power are heredity, state of training, gender, body size and composition, age, and the mode of the exercise (16). A person’s VO2 ...

Vocal Function Exercises For Normal Voice: With And Without Semi-Occlusion, Megan Suzanne Brown

Theses and Dissertations--Communication Sciences and Disorders

The primary purpose of this investigation was to explore the effects of varying degrees of vocal tract semi-occlusion in Vocal Function Exercises (VFEs) on attainment of pre- established maximum phonation time (MPT) goals in individuals between the ages of 18 and 45 with normal voice. Individuals were randomized into three experimental groups: the traditional VFE with a semi-occluded vocal tract (SOVT), modified /o/ with partial occlusion, and modified /a/ without significant occlusion. For six weeks, the participants completed the four exercises two times each, twice daily on corresponding vocal tract postures assigned by group. Results indicated significant change in percent ...

Disaggregating The Relative Influence Of Genetic, Environmental And Individual Factors On Lcl And Hdl Cholesterols And Bmi For A Sample Of African American (Aa) Mothers And Daughters, C. Jayne Brahler, Jewel Harden, Michelle Mchone, Matthew Soules, Eric Evans, Ann Alyanak, Fred Diakpieng, Paul M. Vanderburgh

Health and Sport Science Faculty Publications

There are many reports about the associations between blood lipids, body mass index (BMI) and dietary cholesterol intakes both within the individual and between related individuals. The purpose of this descriptive research project was to investigate the relationships between LDL and HDL cholesterols, body mass index and dietary cholesterol intakes for a sample of African American (AA) mothers and their daughters and to attempt to separate the contribution of genetic versus environmental factors. Mother and daughter participants (n =42 and 66, respectively) were 12-14-hours fasted when blood samples were drawn, heights and weights measured, and 24 hour food recalls completed.

Wrist-Worn Physical Activity Trackers Tend To Underestimate Steps During Walking, Tiffany Sears, Elmer Alvalos, Samantha Lawson, Ian Mcalister, L. Chris Eschbach, Jennifer Bunn

International Journal of Exercise Science

International Journal of Exercise Science 10(5): 764-773, 2017. The purpose of this study was to determine step-count accuracy of pedometers at different walking speeds. Ten recreationally active participants walked at five treadmill speeds (0.89, 1.11, 1.34, 1.56, and 1.79 m/s) for five minutes while wearing four wrist-worn activity trackers (Fitbit Charge HR®, Garmin Vivosmart HR®, Apple iWatch®, Jawbone UP3®) and the hip-worn Digi-Walker®. Each step was manually counted by a research technician (benchmark). Total step count at each speed was obtained for each device and compared to the benchmark using one-way MANOVA and ...

Differences Between Men And Women In Percentage Of Body Weight Supported During Push-Up Exercise, Constance M. Mier, Tal Amasay, Steven Capehart, Heather Garner

International Journal of Exercise Science

International Journal of Exercise Science 7(2) : 161-168, 2014. The purpose of this study was to investigate the effects of push-up method (standard vs modified) and gender on percentage of body weight supported. Thirty seven men and women completed five push-ups in the standard (SPU) and modified (MPU) positions, and 5-sec hold (static) in the up (elbow extension) and down (elbow flexion) positions. Vertical ground reaction forces (expressed as load relative to body weight) were measured using force platforms. From a video-captured image, a computer software distance tool measured vertical range of motion (ROM) achieved in the down position expressed ...

Accuracy Of The Omron Hbf-500 Body Composition Monitor In Male And Female College Students, Michael I. Pribyl, John D. Smith, G Richard Grimes

International Journal of Exercise Science

The Omron HBF-500 is an inexpensive body composition monitor that incorporates both hand-to-hand and foot-to-foot electrical impedance technology. At this time, studies examining the accuracy of the HBF-500 when estimating percent body fat (%BF) are scarce and if this instrument gains popularity due to its claimed precision, comparisons against validated techniques should be conducted. The purpose of this study was to assess the accuracy of the Omron HBF-500 body composition monitor using the BOD POD as a criterion. Forty-eight men and 33 women participated in the study (24.3±6.9 years, 171.0±10.0 cm, 78.4±18 ...

Cardiovascular Disease Risk Factors And Physical Fitness In Volunteer Firefighters, Zachary T. Martin, Rebecca A. Schlaff, Jade K. Hemenway, Jillian R. Coulter, Jeremy L. Knous, John E. Lowry, Joshua J. Ode

International Journal of Exercise Science

International Journal of Exercise Science 12(2): 764-776, 2019. Forty-seven percent of volunteer firefighter line of duty deaths are caused by cardiovascular events. Aggressive cardiovascular disease (CVD) risk factor reduction and improved physical fitness could reduce CVD mortality within this population. We assessed CVD risk factors and physical fitness in a large cohort of volunteer firefighters to help establish a health and fitness profile of this population, which may serve as evidence for the need to initiate programs aimed at reducing morbidity and mortality caused by CVD in the volunteer fire service. Seventy-four male volunteer firefighters were assessed for eight ...
