Abstract / Description
The objective of this study was to determine the effects of a structured weight loss program that included hypocaloric diet, exercise and dietary supplementation, on weight loss, metabolic syndrome risk factors and antioxidant levels in healthy overweight and obese females. Thirty-seven healthy overweight and obese women (BMI 29.5 ± 2.3 kg/m2, 41.1 ± 7.1 yrs) participated in this study. The subjects were randomized into one of two groups: an exercise, hypocaloric diet and antioxidant...

Thirty-seven healthy overweight and obese women (BMI 29.5 ± 2.3 kg/m2, 41.1 ± 7.1 yrs) participated in this study. The subjects were randomized into one of two groups: an exercise, hypocaloric diet and antioxidant supplement (LifePak®; LSANT group, n=20) or an exercise, hypocaloric diet and appetite suppression supplement (HTP Complex® and TēGreen®; LSAS group, n=17). A significant weight loss occurred in both groups after 12 weeks (LSANT: -2.8 ± 2.8 kg and LSAS: -4.3 ± 2.7 kg, p<0.001). Body fat mass, percent body fat, and waist circumference significantly improved in both groups (p<0.05). No significant difference was found between the groups for weight loss (p>0.05). However, a significant difference was found between the groups for body fat mass (LSANT: -1.8 ± 2.6 kg; LSAS: -3.4 ± 2.4 kg, p ≤ 0.05). Glucose, insulin and insulin resistance (HOMA-IR) were significantly decreased in the LSAS group (glucose: -5.0 ± 6.8 mg/dl, p=0.008; insulin: -2.6 ± 3.8 uIU/dl, p=0.013; and HOMA-IR: -0.7 ± 1.0, p=0.012) but not in the LSANT group (p>0.05). There were no significant differences (p>0.05) observed within or between the groups for cholesterol, triglycerides or LDL-c. HDL-c decreased significantly in the LSANT group (-2.9 ± 5.3 mg/dl, p=0.024) but not in the LSAS group (p>0.05). Skin carotenoid scores (SCS) increased significantly within the LSANT group (LSANT: 10950 ± 8395 SCS, p<0.001) but not the LSAS group (p>0.05). Lifestyle intervention that involves a structured hypocaloric diet and increased physical activity results in weight loss and improvements in body composition. However, supplementation with an appetite suppressant (HTP Complex®) did not enhance weight loss beyond what was achieved with a structured lifestyle intervention. Antioxidant supplementation may be of benefit during a weight loss program that incorporates physical activity and a low energy diet.

THE EFFECTS OF A SINGLE EXERCISE BOUT ON PLASMA LEPTIN CONCENTRATION IN OBESE MALES
Title
THE EFFECTS OF A SINGLE EXERCISE BOUT ON PLASMA LEPTIN CONCENTRATION IN OBESE MALES.

Abstract / Description
Recent findings suggest that leptin may be regulated in response to abrupt changes in energy homeostasis. Therefore, it is conceivable that transient changes in energy balance induced by exercise may also regulate leptin synthesis and secretion. As such, we hypothesized that acute increases energy expenditure (i.e. exercise), may regulate leptin concentrations in obese individuals. Fifteen healthy obese males underwent either a single exercise session of moderate intensity (58.4 % ± 4.0 of...
Show moreRecent findings suggest that leptin may be regulated in response to abrupt changes in energy homeostasis. Therefore, it is conceivable that transient changes in energy balance induced by exercise may also regulate leptin synthesis and secretion. As such, we hypothesized that acute increases energy expenditure (i.e. exercise), may regulate leptin concentrations in obese individuals. Fifteen healthy obese males underwent either a single exercise session of moderate intensity (58.4 % ± 4.0 of VO2max) for 60 min (n=8), or served as controls (n=7). The exercise session elicited an energy expenditure of 567±80 Kcal. No significant changes in plasma leptin (pre 23.5± 30.2; post 24.3± 34.3; 24h-post 34.9± 66.6; 48h-post 33.8±64.0 ng/ml), or insulin levels (pre 16.1± 9.2 vs. post 8.1± 9.1; 24h-post 14.3± 9.9; 48h-post 13.8± 10.2 ?U/ml) were detected immediately after the intervention. Baseline plasma leptin levels were positively correlated with BMI (r=0.65; p<0.01), body weight (r=0.64; p<0.01), % body fat (r=0.90; p<0.01) and were negatively correlated with VO2max (r=-0.82; p<0.01). The results of the present study suggest that acute exercise of moderate intensity and duration may not affect leptin concentration.

Show moreFull-body controlled games offer the opportunity for not only entertainment, but education and exercise as well. Refined gameplay mechanics and content can boost intrinsic motivation and keep people playing over a long period of time, which is desirable for individuals who struggle with maintaining a regular exercise program. Within this gameplay genre, dance rhythm games have proven to be popular with game console owners. Yet, while other types of games utilize story mechanics that keep players engaged for dozens of hours, motion-controlled dance games are just beginning to incorporate these elements. In addition, this control scheme is still young, only becoming commercially available in the last few years. Instructional displays and clear real-time feedback remain difficult challenges.This thesis investigates the potential for full-body dance games to be used as tools for entertainment, education, and fitness. We built several game prototypes to investigate visual, aural, and tactile methods for instruction and feedback. We also evaluated the fitness potential of the game Dance Central 2 both by itself and with extra game content which unlocked based on performance.Significant contributions include a framework for running a longitudinal video game study, results indicating high engagement with some fitness potential, and informed discussion of how dance games could make exertion a more enjoyable experience.
