Kinetic Asymmetries During Submaximal And Maximal Speed Running, Devon H. Frayne

Masters Theses

An important issue for sports scientists, coaches and athletes is an understanding of the factors within a running stride that can enhance or limit maximal running speed. Previous research has identified many sprint-related parameters as potential kinetic limiters of maximal Center of Mass velocity (Chapman and Caldwell, 1983b; Weyand et al., 2001). Bilateral asymmetry is present for many of these parameters during running; however the degree to which such asymmetries change as running speed increases is unknown. It was hypothesized that asymmetries in key sprinting parameters would be larger at maximal speed than all other tested speeds. Kinematics and kinetics …

The Effect Of Attentional Focus Instructions On Golf Swing Performance In Recreational Golfers, Jeffrey D. Eggleston

Boise State University Theses and Dissertations

Previous research has addressed the effectiveness of attentional focus instructions in improving golf performance with a single training session. The purpose of the current study was to investigate the effect of external (EF) attentional focus instructions on recreational golfers’ performance over a distributed training period and extended retention interval. Performance was measured by club head velocity (CHV) and X-factor as both have been correlated with greater performance. The current study extends the work of An, Wulf, and Kim (2013), by increasing the training period and retention interval. It was hypothesized EF group would have greater CHV and X-factor measurements during …

Effect Of Training Mode On Post-Exercise Heart Rate Recovery Of Trained Cyclists, Kelia G. Mcdonald, Silvie Grote, Todd C. Shoepe

Health and Human Sciences Faculty Works

The sympathetic nervous system dominates the regulation of body functions during exercise. Therefore after exercise, the sympathetic nervous system withdraws and the parasympathetic nervous system helps the body return to a resting state. In the examination of this relationship, the purpose of this study was to compare recovery heart rates (HR) of anaerobically versus aerobically trained cyclists. With all values given as means ± SD, anaerobically trained track cyclists (n=10, age=25.9 ± 6.0 yrs, body mass=82.7 ± 7.1 kg, body fat=10.0 ± 6.3%) and aerobically trained road cyclists (n=15, age=39.9 ± 8.5 yrs, body mass=75.3 ± 9.9 kg, body fat=13.1 …

Development Of A Prediction Equation For Vertical Power In Masters Level Basketball Athletes, Jordan M. Glenn, Jennifer Vincenzo, Michelle Gray, Ashley Binns

International Journal of Exercise Science

International Journal of Exercise Science 7(2) : 119-127, 2014. Performance factors such as power, agility, and speed are important in sport-based competition for older individuals. Prediction models that assess these factors in masters level competitors are limited. The purpose of this study was to examine physical field measures of agility and speed and their ability to predict vertical power (VP) among basketball masters athletes(MA). Thirty-eight competitive MA from a Midwest Senior Olympic basketball tournament performed vertical jump, 20-yard dash (20-D), 40-yard dash (40-D), and T-test (TT) assessments. Regression analysis revealed a significant relationship (p = .002) using TT and …

Effects Of Carbohydrate And Green Tea Co-Ingestion On Performance, Metabolism And Hormone During Cycling Exercise, Shih-Hua Fang

International Journal of Exercise Science: Conference Proceedings

It has been known that carbohydrate intake during exercise can improve athletic performance, and caffeine can extend exercise endurance. Green tea containing caffeine and various polyphenols has been suggested beneficial to athletes due to anti-oxidative and anti-inflammatory effects. Therefore, this study investigated the influence of carbohydrate and green tea co-ingestion on the performance, metabolism and hormone during high-intensity road cycling exercise.

Nine well-trained male cyclists, aged 17.8 ± 1.0 yr, participated this acute-treatment, double-blind, crossover study that included 6.4-km cycling time trial. Participants ingested carbohydrate (240 mg/kg body mass fructose and 120 mg/kg body mass glucose) without (CHO group) and …

The Effects Of Respiratory Muscle Warm-Up On Exercise Performance And Pulmonary Functions, Dennis Jonathan Guillot

LSU Doctoral Dissertations

Effect of a Specific Respiratory Warm-up on Run Performance, Pulmonary Functions, and Rating of Perceived Breathing The purpose of this study was to evaluate the effect of a respiratory warm-up for five minutes using an inspiratory/expiratory (IEC) device on pulmonary function (PFT) (FVC, FEV©û, FEF 25-75%, PEF), rate of perceived exertional (RPE) breathing, and performance time [300 yard shuttle run (300y) and 1.5 mile run (1.5m)] in asthmatics and non-asthmatics. Ten non-asthmatics males (22.6¡¾7.4 years) participated in phase I, twenty non-asthmatic males (24.2¡¾9.8 years) in phase II, and five asthmatics (20.8¡¾3.2 years) in phase III of this study. The Phase …
