The Effect Of Jogging On Anterior Knee Laxity After Anterior Cruciate Ligament Reconstruction, Fawzi F. Bouzubar Dec 1998

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 Effects Of Dehydration And Rehydration On The One-Repetition Maximum Bench Press Of Weight Trained Males, James E. Schoffstall Oct 1998

The Effects Of Dehydration And Rehydration On The One-Repetition Maximum Bench Press Of Weight Trained Males, James E. Schoffstall

Human Movement Studies & Special Education Theses & Dissertations

The purpose of this study was to examine the effects of dehydration and rehydration on the one repetition maximum (1-RM) bench press of weight trained males. The ten subjects displayed the following characteristics: 25.3 ± 3.2 years old, 85.5 ± 16.4 kilograms body mass and a 117.9 ± 24.0 kilogram base-line 1-RM. Ten subjects were tested on two separate days, with one week between each test day. The subjects were randomly assigned to begin their testing in either the A protocol or the B protocol. During the A protocol testing day, the subjects completed two one repetition maximum bench press …


Patellofemoral Joint Compressive Forces During Backward And Forward Running At The Same Speed, Hesham N. Alrowayeh Aug 1998

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 Aug 1998

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 …


Physiological Effects Of Varying Power Output In A Cycling Time Trial, Mark Alan Liedl Apr 1998

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 Jan 1998

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 Jan 1998

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 Jan 1998

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 …
