The Effect Of Jogging On Anterior Knee Laxity After Anterior Cruciate Ligament Reconstruction, Fawzi F. Bouzubar
Rehabilitation Sciences Theses & Dissertations
Jogging is commonly performed in the latter stages of the rehabilitation program (2½-3 months) following ACL reconstruction. However, its cyclic loading effect on the ACL graft, 4-6 months after surgery has not been examined. Therefore, the purpose of this study was to examine changes in anterior knee laxity before and after 15 minutes of jogging on the treadmill. Subjects (N=l 1) were 8 males and 3 females (X age= 30.27 ± 4.76 years; heights= 175.7 ± 10.7 cm; weights= 81.1 ± 15.9 kg) with unilateral ACL reconstruction (central 1/3 patellar tendon graft, postoperation range = 4-6 months). Measurements were made …

The Relationship Between Physical Activity And Flexibility, Tanya Marie Schramm
Student Work
The purpose of this study was to determine if a relationship existed between flexibility and physical activity levels. Subjects included 128 male (n=64) and female (n=64) volunteers, 19 to 55 years of age. All subjects completed a physical activity questionnaire (which differentiated between work, sport, leisure and total physical activity) and a series of five flexibility tests. Four of the five flexibility tests were completed with the use of a goniometer which measured shoulder flexion, hip flexion, knee flexion and ankle dorsiflexion. The sit and reach test was used to assess hamstring lumbar flexibility. After analyzing the data by using …
The Effect Of Floor Sitting Posture On Low-Back Pain, Knee Pain And Hip Pain Among Kuwaiti Men, Sameera H. Al-Jedi
The Effect Of Floor Sitting Posture On Low-Back Pain, Knee Pain And Hip Pain Among Kuwaiti Men, Sameera H. Al-Jedi
Rehabilitation Sciences Theses & Dissertations
Background and Purpose. Ground resting posture is common in Kuwait and other Arab communities. Kuwaiti men gather daily, especially on weekend nights socializing in the Diwaniya. Diwaniya is a special room in every Kuwaiti house. The Diwaniya is traditionally furnished with seating cushions and pillows. Men are seated on the floor in a tailor-sitting posture for long periods of time. The tailor-sitting posture flexes the trunk. hips, and knees. The flexion position has been shown to decrease the lumbar lordosis and increase joint compression in hips and knees. However there are no studies about the effect of floor sitting …
Patellofemoral Joint Compressive Forces During Backward And Forward Running At The Same Speed, Hesham N. Alrowayeh
Patellofemoral Joint Compressive Forces During Backward And Forward Running At The Same Speed, Hesham N. Alrowayeh
Rehabilitation Sciences Theses & Dissertations
A previous study found that the patellofemoral joint compressive force (PFJRF) during backward running was less than during forward running at free speed. Therefore, the purpose of this study was to compare the patellofemoral joint compressive forces during backward and forward running at the same speed. Ten runners (4 females, 6 males) between the age of 20-25 (X=22, SD=2) ran in backward and forward directions at the slow speed of 2.3 mph (1.0 m.sec-1). Using the inverse dynamic technique the knee extensor moment and PFJRF during the slow backward and forward running were calculated. Results showed that the …
Comparison Of The Emg Activity Of The Supraspinatus And Infraspinatus Muscles During Various Closed Chain Exercises, I-Chen Lin
Rehabilitation Sciences Theses & Dissertations
Advantages of closed chain exercises used in the lower extremity have been well documented. However, the effects of closed chain exercises on the upper extremities have not been studied very much. Thus, the purpose of this research is to analyze the EMG activity of the supraspinatus and infraspinatus muscles and compare the relative amounts of activities by performing different isotonic closed chain exercises and an open chain exercise in normal subjects. The supraspinatus and infraspinatus muscles in 1 o healthy subjects were studied with fine wire, intramuscular, electromyographic electrodes while performing 5 closed chain exercises and a D2. open chain …
Genetic Admixture And Gallbladder Disease In Mexican Americans, Marilyn Tseng, Robert C. Williams, Kurt R. Maurer, Moses S. Schanfield, William C. Knowler, James E. Everhart
Genetic Admixture And Gallbladder Disease In Mexican Americans, Marilyn Tseng, Robert C. Williams, Kurt R. Maurer, Moses S. Schanfield, William C. Knowler, James E. Everhart
Kinesiology and Public Health
Gallbladder disease is a common source of morbidity in the Mexican American population. Genetic heritage has been proposed as a possible contributor, but evidence for this is limited. Because gallbladder disease has been associated with Native American heritage, genetic admixture may serve as a useful proxy for genetic susceptibility to the disease in epidemiologic studies. The objective of our study was to examine thepossibility that gallbladder disease is associated with greater Native American admixture in Mexican Americans. This study used data from the Hispanic Health and Nutrition Examination Survey and was based on 1,145 Mexican Americans who underwent gallbladder ultrasonography …
Analysis Of Serotonin And Postural Instability In Parkinson’S Disease, Sandra Kuniyoshi
Analysis Of Serotonin And Postural Instability In Parkinson’S Disease, Sandra Kuniyoshi
Loma Linda University Electronic Theses, Dissertations & Projects
Postural instability is one of the most debilitating symptoms of Parkinson’s disease and the best clinical prognostic indicator of progressive disease. Significant differences in neuropathology, neurochemistry, response to L-dopa therapy and stereotactic surgery as well as prognosis have been identified in subtypes when patients with predominant postural instability and gait difficulty (PIGD)/Type B were differentiated from those with predominant symptoms of tremor and rigidity/Type A. Postural instability is resistant to the therapeutic effects of L-dopa, despite its continued efficacy on other Parkinson’s symptomatology, implicating the nondopaminergic mechanism of postural instability in Parkinson’s disease. Patients with significant postural instability and gait …

All HMC Faculty Publications and Research
Biologists have traditionally focused on a muscle's ability to generate power. By determining muscle length, strain and activation pattern in the cockroach Blaberus discoidalis, we discovered leg extensor muscles that operate as active dampers that only absorb energy during running. Data from running animals were compared with measurements of force and power production of isolated muscles studied over a range of stimulus conditions and muscle length changes. We studied the trochanter-femoral extensor muscles 137 and 179, homologous leg muscles of the mesothoracic and metathoracic legs, respectively. Because each of these muscles is innervated by a single excitatory motor axon, …
Physiological Effects Of Varying Power Output In A Cycling Time Trial, Mark Alan Liedl
Physiological Effects Of Varying Power Output In A Cycling Time Trial, Mark Alan Liedl
Human Movement Studies & Special Education Theses & Dissertations
During a bicycle time trial, varying power slightly to counter external conditions may result in improved performance [Swain, 1997], but it is not known if such power variations result in added physiological stress. Thus, the purpose of this study was to determine if variable power (VP) cycling produced greater physiological stress than constant power (CP) cycling of the same mean intensity. Eight trained male cyclists (age 28 ± 2 yr, mass 74.4 ± 2.3 kg, VO2max 4.24 ± 0.13 L•min-1, weekly training 277 ± 44 km) performed three 1 h ergometer trials. The first trial was performed …

The Effects Of Habitual Physical Activity On Number Of Colds And Incidence Of Cold Symptoms, Katie Lynn Maniatis
Masters Theses
The purpose of this investigation was to compare frequency of colds and symptoms of upper respiratory infection in college students who have different levels of habitual physical activity. Subjects were Eastern Illinois University students (N=535, aged 18-25). A survey was conducted which included questions inquiring about demographic information, physical activity habits, the number of colds contracted the month before the survey, and symptom number and severity. Data collection occurred between February 12th and March 1st, 1998. This particular time period was chosen for several reasons, including that student stress level should have been lower than at the beginning or end …
A Comparison Of Measures In Physical Fitness And Biological Maturity Between Female Gymnasts And Females Not Involved In Organized Sport, Cara Kokenes
Masters Theses
The purpose of this study was to investigate differences in physical fitness and biological development between two groups of twelve year old females. One group consisted of idividuals who had been involved in competitive sport for at least two years while the other group was not involved in organized sport. Two groups of 20 subjects were examined in terms of height, weight, flexibility, strength, body composition, maturation, eating attitudes, and cardiorespiratory endurance. The results indicated that the gymnasts were significantly (p<.05) shorter, lighter, stronger in regard to left hand grip strength, lower in percent body fat, less biologically mature, and had greater cardiorespiratory fitness than the non-gymnasts. No significant differences were observed in right hand grip strength or eating attitudes. It was concluded that maturation level as well as gymnastic training played a major role in influencing values obtained through measurements of physical fitness.
Sense Of Effort Associated With Exercise In The Chronic Fatigue Syndrome, Karen E. Wallman
Sense Of Effort Associated With Exercise In The Chronic Fatigue Syndrome, Karen E. Wallman
Theses : Honours
Investigations into the mediators of effort sensation have indicated that central mechanisms related to corollary discharges may be responsible for an increased sense of effort during fatiguing isometric exercise. The role for central mediators for sense of effort have been objectively demonstrated through use of contralateral limb matching tasks. Subjects diagnosed with chronic fatigue syndrome (CFS) often report prevalent fatigue associated with a greater sense of effort when involved in exercise. This study employed a fatiguing contralateral limb-matching task in order to determine if CFS subjects (n == 6) experienced an altered sense of effort associated with the task when …
Alcohol, Hormones, And Postmenopausal Women, Matthew P. Longnecker, Marilyn Tseng
Alcohol, Hormones, And Postmenopausal Women, Matthew P. Longnecker, Marilyn Tseng
Kinesiology and Public Health
Many women take supplemental estrogens after menopause, a practice called hormone replacement therapy (HRT). Moderate alcohol consumption may increase estrogen levels in women receiving HRT, potentially affecting their risk for various adverse health effects. Two recent studies, however, provide no strong evidence for an effect of alcohol on hormones in postmenopausal women. The possible association between alcohol consumption and risk of cancer of the breast does not appear to be mediated by estrogens. Both estrogens and moderate alcohol consumption have been associated with a decreased risk for cardiovascular disease; however, alcohol’s beneficial effect on heart disease does not appear to …
