Overcapacity is a self-reflexive, personal journey film that explores the filmmaker's exploration of his lifelong problem with obesity and health. The film follows his progress as he discusses his weight problem with his partner and parents as well as works with a personal trainer and doctor in an effort to affect a lifestyle change while also confronting issues that have led to and perpetuate his current health situation.

This study examined the longitudinal relationship between repetitions in reserve (RIR) and average concentric velocity (ACV) in the back squat and bench press exercises. Fourteen resistance-trained men were randomized into two groups (4-6RIR or 1-3RIR) and completed a six-week program. The RIR/ACV slope was significantly greater (p<0.001) in the bench press (0.027±}0.001m.s-1) than squat (0.020±}0.001m.s-1), and was steeper in 1-3RIR than 4-6RIR (p<0.001). The RIR/ACV relationship varied from set-to-set (p=0.001); however, the largest difference in ACV at the same RIR from set-to-set was only 0.044 m.s-1; likely not practically meaningful. The RIR/ACV relationship changed over time (p=0.004); however, since training was not to failure, it is unclear if this longitudinal change was due to improved RIR accuracy or a true change in the RIR/ACV relationship. Therefore, the RIR/ACV relationship is exercise-specific and practically stable from set-to-set; however, future research is needed to determine the long-term stability of this relationship. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2021. / FAU Electronic Theses and Dissertations Collection

Overtraining is a common problem in athletes that prevents many from becoming "elite". A decrement in an athlete's performance is usually an indicator that overtraining syndrome may be developing. Unfortunately, there is no model that can determine overtraining. A decline in performance results in a depression in maximum muscular force. It is not known whether the force depression is a result of central or peripheral factors. In this study, the two training protocols on different legs determined whether force declines are muscular (peripheral) or psychological (central). Specifically, in this study, the subjects trained one leg at maximal intensity for two weeks, and the other trained at a low intensity for two weeks. After training for two weeks, both legs were placed on a low intensity workout to monitor the recovery process. The purpose of this study was to observe muscle strength performance decrements after overtraining one leg in comparison to properly training the other leg by knee extension exercises for two weeks in trained males. Also, after overtraining the one leg for two weeks, the leg was placed on a reduced training program in order to look at recovery if overtraining occurred. Maximal force output was measured isokinetically on the Biodex three times: pre-, post-, and final test. An analysis of this data revealed no significant changes in maximal muscular force output after a high intensity training protocol. Therefore, this investigation demonstrated that overtraining in the quadricep did not result from the two weeks of high intensity resistance training. / Master of Science

Green weight and green weight per unit volume relationships for loblolly pine trees have not been studied extensively and models for predicting weights across broad geographic areas are not readily available. In this regard three basic interrelated issues were addressed in this study: 1) an examination of weight per unit volume relationships, 2) an assessment of how tree, stand, and geographic characteristics affect weight per unit volume relationships, 3) a derivation of models of weight per unit volume for predicting total bole weight and merchantable weight, 4) a derivation of models for predicting green weight directly, and 5) a comparison of objectives 3) and 4). This study showed that green weight per unit volume varies somewhat within stems, but the variation is large. There is no discernable trend by stand characteristics, and the geographic trends were inconclusive. Data from four data sets were combined and region-wide prediction models for total green weight, green weight to any upper merchantable diameter, and green weight to any upper merchantable height were developed for loblolly pine trees. / Master of Science

Much of the research on obesity has been designed to explore its relationship to the behavior of overeating. Although a number of physiological, societal, cultural and family background variables have been detailed, researchers have sought an approach that does not rely heavily on these considerations. Most weight reduction programs fail to recognize and concentrate on empirically demonstrated differences between obese and normal subjects. Researchers have shown that obese subjects seem to be more sensitive to external than internal stimuli. A behavioral approach to weight reduction that emphasizes and uses these external stimuli was hypothesized to be the treatment of choice. A Self-Modification program was designed to maximize the use of external stimuli. An Aversion Therapy approach that utilized electrostimulation was the alternative treatment procedure. The two treatment procedures were compared with a Control approach. Each of the two treatment approaches and the Control approach consisted of twelve subjects.

Background Human immunodeficiency virus (HIV) sero-prevalence rate during pregnancy was 26% in 2009 in Gauteng. HIV exposure is associated with high morbidity and mortality in infants. Few studies have assessed the effect of HIV exposure on morbidity and mortality in very low birth weight (VLBW) infants. Aim To determine the infant characteristics at birth, morbidity during hospital stay and mortality at hospital discharge of VLBW infants according to maternal HIV status. Methods This was a retrospective cross sectional descriptive study. Hospital records of VLBW infants admitted at the Chris Hani Baragwanath Academic Hospital, Division of Neonatology from 1st January 2011 to 30th June 2011 were reviewed. Data were collected in an Excel spread sheet and imported to STATA version 12 for analysis. Results 302 hospital records of VLBW infants admitted from January to June 2011 were retrieved and reviewed. About a third (34.1%) of VLBW infants were born to mothers who were HIV positive. There were more babies who weighed <1000 grams in the HIV-exposed infants compared to HIV-unexposed infants (p-0.001). HIV exposed infants had a smaller head circumference (p-0.003), a shorter body length (p-0.006) and significantly more severe grades of IVH (p <0.001) compared to HIV unexposed infants. The overall mortality rate in VLBW infants was 27%, with HIV exposed infants having a mortality rate of 38.6% compared to 21% in the HIV-negative infants (p-0.002). Multivariate analysis showed that the main predictor of mortality was birth weight (p<0.001). Conclusion Though on univariate analysis maternal HIV status was associated with mortality in VLBW infants, this effect was not found on multivariate analysis. Therefore the final conclusion from this study is that maternal HIV status has no independent effect on outcomes to hospital discharge in VLBW infants. Birth weight was the predictor of survival in VLBW infants.

Worldwide obesity has increased at an alarming rate since the 1970’s. It has become a considerable health issue in the United States. A third of the population currently qualifies as obese. These numbers strain the healthcare system and result in higher health care costs related to comorbidities such as type 2 diabetes mellitus, hypertension, and hyperlipidemia. Many individuals attempt to lose weight with dietary changes, physical activity, or medications. These strategies can be effective and assist with modest weight loss but they often fail to meet a patient’s expectations or achieve desired weight loss. Therefore, bariatric surgery becomes an attractive option for many people. There are several types available and significant weight loss is seen with some losing over one hundred pounds in the course of year. These dramatic weight losses improve quality of life and improve or eliminate some comorbid diseases. Unfortunately, research shows that about 1.5 to 2 years post operatively, a large proportion of these people experience a weight regain and results are usually not sustained. Seemingly, this weight regain starts to occur due to a lack of structure and support. Prior to bariatric surgery, there are requirements that one must complete including demonstrating weight loss on their own, attending sessions with a nutritionist, and undergoing a psychological evaluation. In contrast, few surgical programs provide patients with this type of structure post-surgically. Thus, this proposed study aims to incorporate a standardized online multi-disciplinary intervention to prevent weight regain after bariatric surgery. Information on weight trends will be recorded at regular follow up appointments and health related quality of life determined by surveys. After completing this intervention, it is predicted that patients will experience fewer weight fluctuations, limited to no recurrence of comorbidities and an improved quality of life.

In response to an increasingly demand for fuel-economy, more weight reduction techniques have been proposed to create an optimum vehicle chassis. Material selection and design modification are two of the vital techniques being investigated. In addition, ample attention has been dedicated towards improving the overall strength of a vehicle chassis. Specifically, the overall objective of this study is to maximize weight savings in a truck chassis, while improving its strength characteristics.

Alcohol consumption and overweight in women are both becoming more prevalent in the United States. Data from NHANES 1999-2000 and 2001-2002 was collected consisting of non-pregnant women between the ages of 20 and 29 years. Variables measured were BMI, drinking occasions, drinking consumption per week, and women?s perception of their weight. Data was analyzed using chi-square in application to SUDAAN to test significance between variables. Results indicated a correlation between weight perception and drinking occasions per week (p-value 0.013). Nutrition implications suggested that individuals who were classified as overweight had more drinking occasions than individuals classified as underweight.
