Development Of An Exercise Test To Predict Vo2max In Children And Adolescents, Nathan E. Black
Development Of An Exercise Test To Predict Vo2max In Children And Adolescents, Nathan E. Black
Theses and Dissertations
The purpose of this study was to evaluate the use of nonexercise (N-EX) data, specifically, the Perceived Functional Ability (PFA) and Physical Activity Rating (PA-R) questionnaires, with the treadmill walk-jog-run protocol to estimate VO2max in 12 to 17 year old boys and girls. Ninety-one participants (49 males and 42 females) took part in this study. Data were collected via PFA and PA-R questionnaires, a walk-jog-run submaximal treadmill test, and a maximal graded exercise test (GXT). Data collected included gender, age, height, weight, PFA and PA-R scores, heart rate (HR), treadmill speed, maximal treadmill grade, respiratory exchange ratio (RER), rating of …
Physiological Differences Between Land And Water Treadmill Running, Rachel Kemp Rife
Physiological Differences Between Land And Water Treadmill Running, Rachel Kemp Rife
Theses and Dissertations
Objective: To determine if water treadmill running with (WTR-S) or without water shoes (WTR-NS) could produce similar cardiorespiratory responses as land treadmill running (LTR). Design and Setting: A repeated measures design was used to assess the differences between LTR and WTR-S and WTR-NS. All testing was done in either a research laboratory or an athletic training hydro-therapy room. Subjects: Eighteen trained runners (9 men and 9 women) volunteered for this study. All 18 subjects participated in three running conditions. Measurements: Treadmill speed, HR, and SF were assessed at four exercise intensities representing 50%, 60%, 70%, and 80% of land VO2max …
The Effect Of Wearing Mouthguards On Vo2, Ventilation, And Perceived Exertion At Two Different Exercise Intensities, Jeffrey Scott Hurst
The Effect Of Wearing Mouthguards On Vo2, Ventilation, And Perceived Exertion At Two Different Exercise Intensities, Jeffrey Scott Hurst
Theses and Dissertations
Objective: To assess the effects of wearing a protective mouthguard during exercise on ventilation and oxygen consumption.
Design and Setting: All participants performed a graded maximal exercise test on a cycle ergometer to determine peak oxygen consumption (VO2peak). Each participant also performed 6 submaximal exercise tests while wearing one of two facemasks (nasal or non-nasal breathing) and one of three mouthguard conditions (no mouthguard, boil and bite, custom-fit). Steady-state VO2, rate of perceived exertion (RPE), and other ventilatory values were measured at 60% and 80% of VO2max during each submaximal exercise test. All 6 submaximal exercise tests were completed within …
An Accurate Vo2max Non-Exercise Regression Model For 18 To 65 Year Old Adults, Danielle I. Bradshaw
An Accurate Vo2max Non-Exercise Regression Model For 18 To 65 Year Old Adults, Danielle I. Bradshaw
Theses and Dissertations
The purpose of this study was to develop a regression equation to predict VO2max based on non-exercise (N-EX) data. All participants (N = 100), aged 18-65 years old, successfully completed a maximal graded exercise test (GXT) to assess VO2max (mean ± SD; 39.96 mL∙kg-¹∙min&sup-1; ± 9.54 mL∙kg-¹∙min-¹). The N-EX data collected just before the maximal GXT included the participant's age, gender, body mass index (BMI), perceived functional ability (PFA) to walk, jog, or run given distances, and current physical activity (PA-R) level. Multiple linear regression generated the following N-EX prediction equation (R = .93, SEE = 3.45 mL∙kg-¹∙min-¹, %SEE = …
