Antecedents Of Regular Exercise Among Women Who Do And Do Not Achieve Weight Loss Over Six Months, Heather Vartanian
Antecedents Of Regular Exercise Among Women Who Do And Do Not Achieve Weight Loss Over Six Months, Heather Vartanian
Dissertations (1934 -)
In the United States, 35.5% of adult women are classified as obese, defined as a body mass index (BMI) of > 30 kg/m2. The health risks associated with obesity can be mitigated through losing even 5-10% of initial body weight. Evidence shows that reductions in caloric intake alone without increases in caloric expenditure leads to a decline in resting metabolic rate, thereby impeding attainment or maintenance of weight loss. The purpose of this cross-sectional, mixed-methods study was to explore the antecedents of regular exercise among women with obesity who did and did not achieve weight loss over six months. The antecedents …

Sex-related differences in physiology and anatomy are responsible for profound differences in neuromuscular performance and fatigability between men and women. Women are usually less fatigable than men for similar intensity isometric fatiguing contractions. This sex difference in fatigability, however, is task specific because different neuromuscular sites will be stressed when the requirements of the task are altered, and the stress on these sites can differ for men and women. Task variables that can alter the sex difference in fatigability include the type, intensity and speed of contraction, the muscle group assessed and the environmental conditions. Physiological mechanisms that are responsible …
