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 ...


The Cardiovascular Effects Of Resistance Exercise Training On Orthostatic Intolerance In Elderly Individuals., Lynn P. Rhea May 2001

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 ...

Investigation Of The Differences Between Inertial And Cadence Effects On Neuromuscular Coordination During Cycling, Brian Svercauski Baum Jan 2001

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 ...

Determining The Termination Percentage Of Heart Rate Maximum For Submaximal Testing, Julia A. Valentour Jan 2001

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 ...

The Relationship Between Jealousy And Self-Esteem In Collegiate Athletes, Paula M. Parker Jan 2001

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 relationship between social comparison jealousy and team cohesion using the Social Comparison Jealousy Scale (SCJ, Pease, 1987) and found a nonsignificant negative correlation between jealousy and team cohesion. Schelling and Huddleston (1999) administered the Sport Jealousy Scale (SJS; Schelling & Huddleston, 1999)), a sport-specific measure of jealousy, to track and field athletes and found they were "moderately jealous." Kamphoff(2000) utilized a newer version ofthe scale, the Revised Sport Jealousy Scale (SJS-IV), and found a significant negative correlation between jealousy and team cohesion, as well as gender differences in jealousy. The purpose of the present investigation was to further examine differences in jealousy among collegiate athletes. Differences ...


The Effect Of Moderate +Gz On Cervical Muscle Strength Of Raaf Trainee Pilots Flying Pc-9 Aircraft, Elissa Jane Burton Jan 2001

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 ...
