The Effects Of A Commercial Nutritional Supplement Combining Amino Acids, Glutamine, Carnitine And B-Vitamins On The Physiological Responses To Ultraendurance Triathlon Training, Performance And Recovery, Mary V. Mitchell

Human Movement Studies & Special Education Theses & Dissertations

In a placebo, double blind, randomized design, five male triathletes participated in a simulated triathlon which examined the physiological responses of a commercial nutritional supplement. The supplemental protocol included 7.1 gm·d^-1 of an amino acid complex with B-vitamins (AA) and between 2.2-7.3 gm·d^-1 META-MAX™ containing leucine, isoleucine, valine, glutamine and carnitine in which quantities were based on the athletes training volume. A maltodextrin carbohydrate replacement drink was also included in the protocol. The placebo was an isocaloric lactose substance. The supplements were ingested for 14 d prior to the simulated triathlon and then for 3 d after the …

The Effects Of Varying Doses Of Orally Ingested Bee Pollen Extract Upon Total Exercise Time To Exhaustion Performance Recovery And Ratings Of Perceived Exertion, Michael Lee Woodhouse

Human Movement Studies & Special Education Theses & Dissertations

The purpose of the present investigation was to study the effects of varying doses of orally ingested bee pollen extract upon (1) treadmill run time to exhaustion and (2) initial ratings of perceived exertion (RPE) . Subjects consisted of five male aerobically trained athletes with an age range of 21 - 35 years. The subjects individually volunteered for the study and were active members of a local running club, The Tidewater Striders.

The bee pollen was given in three dosages (0, 1350 mg, 2700 mg). The three test periods on the treadmill consisted of six runs to exhaustion with a …

The Effect Of Blood Infusion Upon Perceived Exertion, Mary Aubert Lindhjem

Human Movement Studies & Special Education Theses & Dissertations

The purpose of this study was to determine the effect of packed RBC infusion upon ratings of perceived exertion (RPE), Three types of RPE were measured: 1) local muscular RFE, 2) cardiopulmonary RPE, and J) general RFE, The subjects, 16 experienced long distance male runners, undertook four treadmill runs to exhaustion, Subjects were matched according to time to exhaustion (ET) on the first trial (T1), and assigned to either an experimental (E) or control (C) group, Both groups had 46o ml blood withdrawn following Tl, T2 served as a baseline test and was administered about two weeks following blood withdrawal, …

The Effect Of Iron Supplementation On The Endurance Capacity Of The Female College Athlete, Barbara B. Sachon

Human Movement Studies & Special Education Theses & Dissertations

The major parameter of interest was the effect of iron supplementation on endurance capacity of female college athletes. Secondary parameters included the evaluation of the effect of iron supplementation on the following hematological variables: white blood cell count, red blood cell count, hemoglobin concentration, and hematocrit. Nineteen volunteer female students enrolled at the College of William and Mary in Williamsburg, Virginia served as subjects, All were members of the swimming team. All test trials and venipunctures were done at the women's gym at the College of William and Mary. There were two test periods.

All nineteen subjects performed a 500 …

The Effect Of Various Doses Of Caffeine Upon The Maximal Muscular Endurance Of College Females, Roberta Jane Perkins

Human Movement Studies & Special Education Theses & Dissertations

A limited number of investigations dealing with the effects of caffeine upon human physical performance have been conducted. Since caffeine is a central nervous system stimulant and it is a constituent of the popularly-consumed beverages - coffee, tea, and cola drinks, it would appear that numerous studies would have been conducted in order to determine the effect of caffeine upon human muscular performance. At any rate, there is a dearth of studies on this topic and the findings of the conducted experiments are equivocal and ambiguous.

The purpose of the present study was to determine the effects of various doses …

A Comparison Of Selected Isokinetic Training Velocities On The Development Of Muscular Power In College Women, Julia P. Knight

Human Movement Studies & Special Education Theses & Dissertations

The purpose of this study was to compare the effects of three different isokinetic velocities on the development of muscular power. Seventy-five college females were matched into four equal groups according to the average of their pre-test scores on the Vertical Power Jump Test and the Power Staircase Test. Group I served as the control group, while all 3 of the experimental groups performed the same isokinetic exercise at different pre-set rates of speed. Groups II, III and IV worked at the selected rates of .8, 2.3 and 3.9 inches per second respectively. All four groups were pre-tested and post-tested …
