Thirty-nine overweight college women were assigned to one of three weight reduction groups: diet control (DC), DC + low intensity exercise (LX), DC + moderate intensity exercise (MX). All women were tested for VO₂peak and percent fat. The DC included a previously designed nutrition education and behavior modification program held one time per week which prescribed a caloric intake based on body weight to result in a 1000 kcal•day⁻¹ dietary deficit. Exercise groups were asked to also attend three exercise sessions each week. In addition to a warm up and cool down, LX exercised at a heart rate corresponding to 40% of VO₂peak for 35 minutes per session while MX exercised at 70% of VO₂peak for 20 minutes. Exercise durations were chosen to match LX and MX for total exercise caloric expenditure. Heart rates were self-monitored every 10 min and sporadically verified by the exercise leader. At the end of the 8 week program, there was an overall drop out for the three groups of 34%, with the DC group having the highest attrition (50%) relative to LX ( 40%) and MX (20%) groups. VO₂peak did not change significantly after the 8 week program in any group, perhaps as a function of the modest exercise stimulus and/or a sharp reduction in attendance noted in the final 2 weeks. However, an improvement in cardiorespiratory efficiency was indicated by the significant reduction of heart rate at submaximal workload III (MX = -12, LX = -10, DC = -6 bts·min⁻¹ ). A significant mean decrease of 2.93 ml·kg⁻¹·min⁻¹ in VO₂ at the same submaximal workload was noted. All groups lost a significant amount of body weight over the eight weeks. The trend in average body weight loss (DC=4.0, MX=3.6, LX=3.3 kg) was opposite to that of % fat loss (LX = 5.1, MX = 3.9, DC= 2.2%). These differences were not significant but show a tendency for exercise coupled with diet control to enhance fat but not total body weight loss. Thus, the treatment which enhanced fat loss and most strongly enhanced attendance was a moderate intensity exercise added to diet control. / Master of Science

The purpose of the investigation was to determine the interrelationships of strength, speed, power and anthropometric measures in women. Sixty females ranging in ages from 18 to 25 volunteered as subjects. Subjects were measured for strength on the bench press, leg extension and leg curl, power vertical jump, speed--a 40 yard dash, body weight (BW) and fat weight (FW) using a scale and skinfold tests. The correlations for strength and power (.35 to .53), strength and speed (-.37 to -.56) and speed and power (-.45) were significant (p < .01). Partial correlations with (BW) and (FW) held constant were also significant, but were not significantly greater than their zero-order correlations.

PURPOSE: The purpose of this study was to compare relationships between dietary and physical activity (PA) behaviors and body composition and body fat distribution, as measured by percent body fat (BF%), waist-to-height ratio (WHt), waistto- hip ratio (WHp) and body mass index (BMI) in post-menopausal women (Post), with the same relationships in pre-menopausal women (Pre). METHODS: Ninety-two subjects (n = 48 Post; n = 44 Pre) were measured for height, weight, waist and hip circumferences and skinfold thicknesses. Dietary content was obtained from a Diet History Questionnaire (DHQ II); PA was estimated from responses to the International Physical Activity Questionnaire (IPAQ). RESULTS: Multiple regression identified no modifiable predictor variables for Pre. Models for Post identified saturated fat grams (SFGs), PA, years postmenopause (YrsPost), and Alcohol (Alc) as predictors of WHt, WHp, BMI and BF%. CONCLUSIONS: PA, SFG and Alc are modifiable variables related to postmenopausal body composition and fat distribution. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2017. / FAU Electronic Theses and Dissertations Collection

The primary purpose of this study was to investigate the effect of training at a particular time of day on anaerobic capacity in the morning and in the afternoon.

The present investigation was designed to examine the effects of the positive manipulation of information on self-efficacy and subsequent performance of 180 female subjects. High, moderate, and low self-efficacy subjects were randomly assigned to a treatment condition in a 3 x 4 x 3 (preexisting self-efficacy x efficacy information source x trials) factorial design. Information from the three efficacy sources of performance accomplishments, verbal persuasion, and vicarious experience was manipulated towards success after subjects completed a muscular leg endurance task. The results supported self-efficacy theory with high self-efficacy subjects extending their legs significantly longer than moderate and low self-efficacy subjects. However, subjects did not differentially [sic] respond to the manipulation of the efficacy information. Results are discussed in terms of efficacy as a mediator of performance on an endurance task as well as the lack of differential changes in efficacy based on the source from which that information is derived.

The aim of this study was to describe the behaviour and perceptions of women in aerobic or exercise to music classes. In particular, the study examined the meaning women attach to this activity choice and the interaction of aerobics participation with cultural pressures and beliefs such as that of the ‘ideal female bodyshape’. A naturalistic method of study was chosen in order to gain a comprehensive view of the subjective experience of aerobics participation. Approximately fifty female health club members were observed over a three month period in order to identify and describe patterns of involvement, behaviour and perception and the factors affecting them. Six groups of women were identified. These were ‘Naturals’, ‘Compulsive’, ‘Functional Feminist’. Several factors were observed as potentially contributing to the patterns observed. These included attitude toward perceived cultural ideals and pressures of female expectation and shape, perceptions of aerobics and exercise, pre-occupation with slenderness and bodyshape, self-image and body image. The relationship between these factors was found to be dynamic and reciprocal, with participation possibly intensifying or alternately reducing bodyshape concern. Aerobics was seen to have a multifaceted yet very individual and important appeal to the women observed.
