Acute exposure to vibration has been suggested to produce transient increases in muscular strength (1,2,8), vertical jump displacement (4,8), and power output (2,6,7) recorded while performing various tasks. It has been hypothesized that the reported acute vibration induced increases in performance occur as a result of alterations in neuromuscular stimulation (1,3,4). Specifically, most studies have ascribed the observed improvements to the likeliness of Whole Body Vibration (WBV) in producing a “tonic vibration reflex” (TVR) in which the primary nerve endings of the Ia afferents of the muscle spindle are activated. This is thought to result in the excitation of the …

With the belief that theoretical integration in motivation may help us better understand motivational behavior, we designed this study to explore adolescents’ motivational profiles and their associations with knowledge acquisition, leisure-time exercise behaviors, and cardiorespiratory fitness. Middle school students from a large urban inner-city school district (N = 603, ages 12–14) completed questionnaires assessing motivational constructs and leisure-time exercise behavior. Knowledge and cardiorespiratory fitness were also assessed with a knowledge test and the Progressive Aerobic Cardiovascular Endurance Run (PACER) test, respectively. Using hierarchical cluster analysis, we found that students’ motivation in physical education could be explained from a multi-theoretical …
The Effects Of Repeated Anaerobic Bouts On Immune Parameters, James C. Sivley
The Effects Of Repeated Anaerobic Bouts On Immune Parameters, James C. Sivley
Masters Theses & Specialist Projects
To date, the exercise-induced immune response in has only been evaluated in subjects performing aerobic exercise. The primary purpose of this study is to determine if repeated bouts of anaerobic exercise will induce a similar immune response in human subjects as exhibited by aerobic exercise. Secondary to immune function, an analysis of performance from trial to trial will be made. Nine males between the ages of 18-25 were selected on a volunteer basis to participate in this study. Subjects performed Wingate tests set in 3 series with 120 seconds between trials within series and 405 seconds between series for an …
The Effect Of A Commercially Available Caffeine Based Dietary Supplement On 40-Kilometer Time Trial Performance, Lee A. Weidauer
The Effect Of A Commercially Available Caffeine Based Dietary Supplement On 40-Kilometer Time Trial Performance, Lee A. Weidauer
Electronic Theses and Dissertations
Purpose: To determine wheather ot not the nutritional supplement PreRace containing L-Taurine, Citrulline Malate, Quercetin, DiMethyl Amino Ethanol, Caffeine, Metabromine, Catechin, and Malic acid will improve performance in an indoor 40 Kilometer cycling time trial.
Methods: Seven male cyclists ages 21-58 participated in a placebo-controlled investigation which consisted of two trials in which they consumed either the supplement PreRace or aloe vera juice. In each of the trials the placebo or supplement was mixed with a sports beverage. Subjects performed a 40 kilometer time trial and measurements of oxygen consumption and lactate were taken every 15 minutes as well as …
