Comparison Of Black And White Elderly Women On Muscle Mass Bone Mineral Density And Balance., Tyanez Jones

Electronic Theses and Dissertations

Few studies have compared balance between aging black (BW) and white women (WW) and examined its relationship to muscle mass and bone mineral density (BMD). Nineteen BW and 56 WW between 60-91 years participated. Upper and lower body strength, body composition, BMD, volitional and non-volitional control of dynamic balance, and physical activity ratings were assessed. There were no differences in strength between the groups. A trend was reported for total body BMD (p=0.07). WW exhibited better control of rapid volitional movements, in the limits of stability and rhythmic weight shift tests. The relationships of strength and muscle mass to BMD …

The Cardiovascular Effects Of Resistance Exercise Training On Orthostatic Intolerance In Elderly Individuals., Lynn P. Rhea

Electronic Theses and Dissertations

One of the age-related changes associated with normal aging is the inability to maintain normal blood pressure homeostasis, a common clinical condition known as orthostatic intolerance. There are little data on the effects of strength training in healthy adults and orthostatic intolerance, and only one study on strength training and elderly adults diagnosed with orthostatic intolerance. Therefore, the purpose of the present study was to evaluate the effects of resistance training on the cardiovascular respones of elderly individuals during an orthostatic challenge.

Thirteen subjects were assigned to either a resistance (RES; n=7; 66±5 yrs.) or a control (CON; n=6; 71±6 …

A Comparison Of The Effects Of Interval Training Vs. Continuous Training On Weight Loss And Body Composition In Obese Pre-Menopausal Women., Jeffrey Warren King

Electronic Theses and Dissertations

The purpose of this study was to investigate the role exercise intensity plays in reducing body weight and percent body fat in overweight women. Subjects were randomized to either a high intensity interval training group (IT) or a lower intensity steady state training group (ST). Each group exercised 3 times per week for 8 weeks and expended 300 kcal per exercise session. VO₂max, body composition, and resting metabolic rate (RMR) were measured pre and post training. RMR was measured after exercise at week 2 to see if intensity levels affected RMR. VO₂max and body composition improved …

Isokinetic Dynamometer Versus A Multi-Axial Stability Platform In The Proprioception And Strength Training Of The Peroneal Muscle Group, Eric Johnson

Theses, Dissertations and Capstones

Ankle injuries are the most common and frequent occurring injuries in sports today (Feuerbach, Grabiner & Koh, 1994). Ankle sprains usually occur in athletes that are participating in running or jumping activities. Injuries to the ankle joint represent about 20% of all sports related injuries, and 15% of all time lost injuries (Payne, Berg, & Latin, 1997). The majority of the sprains to the ankle occur to the lateral ligamentous structures due to the forcefully plantar flexion and inversion of the talocrural joint. This inversion mechanism accounts for 85% of all ankle sprains (Kinzey, Ingersoll, & Knight, 1997). Often after …

Influence Of Short-Term Endurance Exercise Training On Heart Rate Variability, Clarence Matthew Lee

LSU Doctoral Dissertations

The purpose of this investigation was to determine if 8 exercise endurance training (ET) sessions over 2 weeks significantly alters cardiac autonomic modulation, as measured by heart rate variability (HRV). Twenty-four college-aged males were recruited for this study and were randomized into either an exercise group (EX; n=12) or a control group (CT; n=12). EX underwent 2 weeks of ET on a cycle-ergometer (frequency: four times/week; duration: 40 minutes; intensity 80-85% HRreserve), whereas CT was instructed not to alter their previous level of physical activity. Five-minute ECG tracings were collected for HRV under the following conditions: 5 minutes of paced …

Investigation Of The Differences Between Inertial And Cadence Effects On Neuromuscular Coordination During Cycling, Brian Svercauski Baum

LSU Master's Theses

Muscular activity and coordination may be influenced by movement speed and the inertial properties of the limbs. Some observed effects from investigations using cycling have been attributed to inertia, especially at greater pedaling speeds (cadences); however, in these investigations, movement speed and inertia were coupled. Therefore, the purpose of this experiment was to investigate and distinguish between the effects of cadence and inertial influences on lower extremity neuromuscular coordination during cycling. This was achieved by subjects cycling at different cadences and with different loads attached to the distal ends of their thighs. Electromyographic (EMG) data of seven lower extremity muscles …

The Effects Of Strength Training On The Bone Mineral Density Of Aerobically Trained Perimenopausal Women, Jill Marie Kowalski

Masters Theses

The purpose of this study was to determine if a strength training program has an effect on the bone mineral density of aerobically trained perimenopausal women. The study also hoped to determine if high intensity strength training with low repetitions will result in a greater increase in bone density as compared with low intensity strength training with high repetitions. The duration of the study was six months.

The participants were twenty-five aerobically trained perimenopausal female volunteers. They were randomly selected to be in one of three groups. Group 1 was the aerobic control where the participants continued with their aerobic …

The Effect Of Moderate +Gz On Cervical Muscle Strength Of Raaf Trainee Pilots Flying Pc-9 Aircraft, Elissa Jane Burton

Theses : Honours

External stimulus/loading initiates adaptations within skeletal muscle. Whilst performing flying manoeuvres under +Gz it has been previously found that the cervical area has the highest loading. The purpose of this study was to examine cervical muscle response to moderate +Gz force (+4-6Gz) loading generated during RAAF pilot training. Cervical muscle strength was monitored in nine RAAF pilots completing an eight-month flight training course and ten controls matched for gender, age, height and weight. Cervical muscle strength and range of movement were measured at baseline and at eight months using the Multi-Cervical Rehabilitation Unit (Hanoun, Canada). Also measured, using EMG, was …

The Time-Course Of Vascular Adaptations Following Localized Short Term Exercise Training, Jason David Allen

LSU Doctoral Dissertations

This is a series of 3 experiments in the area of vasoreactivity. The first study investigated the stability and reproducibility of brachial artery flow-mediated dilation (BAFMD). Twenty-six healthy volunteers underwent 3 scans on 2 days, performed by 2 ultrasonographers, and analyzed by 2 readers. All subjects were tested between 7 and 11am after refraining from food and exercise. Average baseline diameter was 3.48±0.53mm, which increased to 3.71±0.57mm (6.58±4.15%) at peak dilation. ICCC's for days, testers and readers were 0.9188, 0.9394, and 0.8982 respectively. To detect a difference in vasoreactivity of 60% (two-tailed), e.g. 5% vasodilation versus 8% vasodilation, at 90% …

The Relationship Between Jealousy And Self-Esteem In Collegiate Athletes, Paula M. Parker

Legacy ETDs

Previous research has found contradictory results when examining the possible relationship between jealousy and self-esteem (Guerrero & Afifi, 1998, Mathes & Severa, 1981; Mikulincer, Bizman, & Aizenberg, 1989, Peretti & Pudowski, 1997; Stewart & Beatty, 1985; White, 1981). Jealousy has been most often researched in romantic relationships (Peretti & Pudowski, 1997; Salovey & Rodin, 1986) and social comparison situations (Bers & Rodin, 1984, Mikulincer, Bizman, & .Aizenberg, 1989). Few studies have examined jealousy in an athletic setting. Sport jealousy has received little attention because until recently, there was no reliable instrument to measure jealousy in sport. Pease (1987) investigated the …

Determining The Termination Percentage Of Heart Rate Maximum For Submaximal Testing, Julia A. Valentour

Legacy ETDs

BACKGROUND: In the Fourth Edition of the American College of Sports Medicine's Guidelines for Exercise Testing and Prescription (1991). the protocol for the ACSM's submaximal bike test was to terminate the test at 65-70% of the age predicted maximal heart rate. In the Fifth Edition, this was changed to 85% of the age-predicted maximal heart rate.

OBJECTIVES: The purpose of this study was to find out, by using the ACSM submaximal cycle ergometer test (see Appendix A) if the 85% heart rate maximum termination provides a more accurate estimate of maximal aerobic capacity than the 70% heart rate maximum termination. …
