Effects Of Instability On Core Muscle Activation In A Side Bridge, Erin E. Kishman
Effects Of Instability On Core Muscle Activation In A Side Bridge, Erin E. Kishman
Masters Theses
Training the musculature of the core continues to be perceived as an essential component of conditioning and rehabilitation settings (11). A popular way to train the core is with the use of instability devices, such as Swiss ball or suspension trainer. However, there is limited research on the effects of these devices on core muscle activity. The purpose of this study was to examine core muscle activity during side bridge variations with and without instability devices (Floor, Swiss Ball, and TRX) through electromyography (EMG) of the rectus abdominis, external oblique, erector spinae, and latissimus dorsi. 39 participants performed three variations …
The Effects Of Ovarian Hormones And Exercise On Gene Markers Of Cardiac Dysfunction, Anisha S. Patel
The Effects Of Ovarian Hormones And Exercise On Gene Markers Of Cardiac Dysfunction, Anisha S. Patel
Masters Theses
Heart disease is the leading cause of death in women in the United States. Premenopausal women appear to have better cardiac function and lower risk of heart disease compared to male postmenopausal female counterparts. Ovarian hormone loss influences blood pressure homeostasis and causes systemic inflammation, which may result in chronic stress on the heart. Two key physiological changes in cardiac dysfunction are reemergence of the fetal gene pattern and myocardial remodeling. Physical activity has been linked to improved cardiac function. The purpose of this study was to investigate the effects of ovariectomy on early markers of cardiac dysfunction and fibrosis …
Why Is There Still So Much Confusion About Vo2 Plateau? A Re-Examination Of The Work Of A.V. Hill, Richard Vincent Castle
Why Is There Still So Much Confusion About Vo2 Plateau? A Re-Examination Of The Work Of A.V. Hill, Richard Vincent Castle
Masters Theses
Maximal oxygen uptake (VO2max) is regarded as the gold standard for assessing aerobic fitness. In 1923, Hill et al. proposed that VO2max represents the maximal ability of the body to take in and consume O2 during strenuous exercise. Recently, however, controversy has arisen over the issue of whether a leveling off, or "plateau" in VO2 is necessary to verify attainment of VO2max. Purpose: To compare two different VO2max protocols and determine if both protocols show direct evidence of an upper limit on VO2. Methods: Nine runners (18-35 years old) completed …
