Mathematical Modeling Of Heart Rate Deflection Point In Relation To Respiratory Compensation And Treadmill Running Performance, Kayla Baker
Electronic Theses and Dissertations
Heart rate deflection point (HRDP), identified as the second breakpoint in the "intensity / heart rate" relationship, is indicative of the anaerobic threshold (AT). This point can be determined via bi-segmental linear regression (2SEG) or through use of the maximal distance model (D-max); however, the relationship between these methods has yet to be investigated 2. Purpose: To compare the use of 2SEG and D-max methods to determine HRDP and to examine the relationship between these values with a metabolic threshold, respiratory compensation point (RCP), as well as running performance [5,000 meter treadmill time trial (5Ktime)]. Methods: Nineteen recreationally active men …
The Reproducibility And Validity Of Using The Dmax Method To Predict Physical Working Capacity At Fatigue Threshold, Joshua Riffe
The Reproducibility And Validity Of Using The Dmax Method To Predict Physical Working Capacity At Fatigue Threshold, Joshua Riffe
Electronic Theses and Dissertations
Although the original (ORG) physical working capacity at fatigue threshold (PWCFT) assessment has demonstrated strong reliability and sensitivity to training and/or nutritional interventions, limitations may exist regarding the method of PWCFT estimation. However, a relatively new mathematical method, called Dmax, has been shown to be objective and reliable when estimating metabolic and neuromuscular fatigue thresholds. To date, however, no study has examined whether the Dmax method for estimating the work rate at PWCFT is similar to the ORG method. PURPOSE: The purpose of this study is to evaluate the reliability and validity of the Dmax-EMG method for estimating and tracking …
Effects Of A 10-Week Introductory Judo Course On Postural Control During Reactionary Bilateral Gripping Task With Varied Stances And Lower Body Power Performance, Tyler Muddle
Electronic Theses and Dissertations
PURPOSE: The purpose of the present study is twofold: 1.) Examine the effects of 10-weeks of an introductory judo course on postural control during maximal bilateral isometric handgrip testing using different stance conditions and lower body power performance, and 2.) To analyze the relationship between maximal bilateral handgrip exertions on postural control during varied stance conditions. METHODS: Twenty recreationally active men and women divided into two an experimental group, (JDO) (n = 10; 21.70 ± 3.83 y; 169.91 ± 6.01 cm; 73.89 ± 12.10 kg; 19.01 ± 8.06% BF), and a control group, (CON) (n = 10; 21.50 ± 2.84 …
Therapy Options For Winged Scapula Patients: A Literature Review, Samantha L. Normand
Therapy Options For Winged Scapula Patients: A Literature Review, Samantha L. Normand
Honors Undergraduate Theses
Winged scapula is a condition characterized by lateral or medial protrusion of the scapula caused by nerve damage leading to muscular paralysis. The purpose of this systematic review of literature is to evaluate the current research literature related to the effectiveness of therapy options for winged scapula. Eleven peer reviewed English language research articles published from 1998 to present were included for evaluation. Study results revealed positive therapeutic outcomes for physical therapy and scapular bracing. Results also showed positive outcomes for the use of transcutaneous electrical nerve stimulation and acupuncture for the treatment of nerve related conditions similar to winged …
The Effects Of Resistance Training Frequency On Muscle Hypertrophy And Strength In Healthy Trained Individuals: Literature Review, Alexander C. Boivin
The Effects Of Resistance Training Frequency On Muscle Hypertrophy And Strength In Healthy Trained Individuals: Literature Review, Alexander C. Boivin
Honors Undergraduate Theses
The purpose of this study is to determine the effects of increased resistance training frequency on strength and hypertrophy in trained individuals. Six Studies were deemed eligible based on the inclusion exclusion criteria. The inclusion criteria for this review were healthy trained individuals. “Trained” refers to over one year of resistance training experience. Exclusion Criteria were study’s that examined either untrained or obese individuals as participants. The evidence indicates a dose-response trend in frequency. Resistance training each muscle group twice a week may be superior compared to once per week. Further more, resistance training each muscle group three times a …
Evaluation Of Echogenicity Within And Between Ultrasonographic Images Of The Vastus Lateralis, Alyssa Varanoske
Evaluation Of Echogenicity Within And Between Ultrasonographic Images Of The Vastus Lateralis, Alyssa Varanoske
Electronic Theses and Dissertations
PURPOSE: The purpose of this study was to examine the echo intensity (EI) values of different ultrasound (US) images of the vastus lateralis (VL) using panoramic imaging in the transverse plane (PTI) and still imaging in the longitudinal plane (SLI). Secondary purposes of this study were to examine VL homogeneity and to determine relationships between subcutaneous adipose tissue thickness (SubQ) adjacent to the muscle and EI. METHODS: Twenty-four recreationally trained collegiate males (20.2 ± 1.6 years; height: 178.1 ± 6.6 cm; weight: 82.2 ± 13.4 kg) participated in this investigation. EI, cross-sectional area (CSA), muscle thickness (MT), and SubQ of …
