From Young To Old: The Effects Of Sedentary-Aging And Exercise Interventions On Structural Plasticity Of Lumbar Motor Neurons, Nmj, And Glial Cell Line-Derived Neurotrophic Factor Expression, Alberto Felipe Cintron-Colon

Dissertations

Neuromuscular weakness has been associated with age progression. A possible reason is a disconnection between muscle and neuron, causing components from both the central and peripheral nervous systems to deteriorate. Exercise, however, has beneficial effects for both muscle and nervous tissue, inducing neuroprotection. Neurotrophic factors are powerful regulators of neuronal maintenance and synaptic strength. Glial cell line-derived neurotrophic factor (GDNF) is a neurotrophic factor that has been shown to be a potent survival factor for somatic motor neurons that innervate skeletal muscle.

This study aims to evaluate changes in structural plasticity of motor neurons in the lumbar spinal cord and …

A Kinematic And Kinetic Analysis Of First, Fourth, And Fifth Positions In The Classical Ballet Method, Mary Sue Hill

Masters Theses

The problem of the study was to compare electromyography (EMG) responses, ground reaction forces, and torques on female college-age dancers' knees in selected positions. Subjects were 18 female dancers, aged 18 to 30 years, with 6 subjects from each of three levels: Ballet Technique I, II, and III. The rectus femoris, vastus lateralis, and vastus medialis were analyzed in a grande plie in three positions, (1) first, (2) fourth, and (3) fifth, with two phases: (1) eccentric, and (2) concentric. No differences in force or EMG data were found for the concentric phases of the three positions. Significant differences were …

The R Value At Vo2 Max During Maximal Graded Exercise Treadmill Tests Of Coronary Artery Diseased And Nondiseased Subjects, Sherry S. Williams

Masters Theses

This study examined the R value at VO2 max during maximal graded treadmill exercise tests to determine if it was a reliable indicator of VO2 max and could therefore be used as a test termination criterion. The subjects in this study were 160 coronary artery diseased (CAD) patients and 170 nondiseased individuals. Data were collected from existing stress test records. The R value was also analyzed to determine if proportions of diseased and nondiseased subjects were the same. The time it took 100 CAD patients to reach VO2 max and exhaustion once R rose above 1.00 was also examined.

Total Blood Cholesterol, Blood Triglyceride, And Blood Hdl Correlation, Rebecca Lynn Babler

Masters Theses

The purpose of this investigation was to determine the relationship between total blood cholesterol levels, blood triglyceride levels, and blood HDL levels in men and women 20 to 80 years of age. All subjects fasted for 12 hours prior to having their blood drawn.

The computer program SPSSX (SPSSX, Inc., 1988) was used along with subprograms CONDESCRIPTIVE, CORRELATION, and ANOVA. Pearson Product Moment Correlations were calculated for all subjects, for male subjects, and for female subjects.

The study revealed a low correlation coefficient between blood cholesterol levels and blood triglyceride levels for all subjects, female subjects and male subjects. There …

Kinetic Studies Of The Cell Elongation Phenomenon In Etiolated Pisum Stem Segments, Grant M. Barkley

Masters Theses

The short-term growth response of etiolated pea stem segments (Pisum sativum L., var. Alaska) was investigated using a high-resolution growth recording device. The immediate effect of treatment with indoleacetic acid (IAA) is an inhibition of growth. This inhibition lasts about 10 minutes and then the rate of elongation rises abruptly to a new steady rate about 4 times the rate of elongation before auxin treatment. This rapid steady rate of elongation, however, continues for only about 22 minutes before declining suddenly to a lower steady rate of growth about 2 times the rate of elongation before the addition of auxin. …
