Four-day dietary records, the International Physical Activity Questionnaire (IPAQ), and dual energy X-ray absorptiometer (DEXA) determined see more body compositionmeasurements were obtained at 0, 4, 10, & 16 weeks and analyzed by MANOVA with repeated measures. Data are presented as changes from baseline for the WL and AG groups, respectively, after 4, 10, and 16 weeks. Results No significant differences were observed in energy intake or macronutrient intake among those in the AG or WL groups. The amount of vigorous PA performed at each data point in the AG group was significantly

greater throughout the study (WL 953±1,221, 844±653, 1,338±1,767, 1,266±1,535; AG 803±1,282, 1,332±1,719, 1,286±1,974, 1,579±2,091 MET-min/wk, p=0.01) despite even distribution of participants among supervised and check details non-supervised exercise programs. Overall, MANOVA revealed a significant time by intervention effect (p=0.02) in 4SC-202 order body composition variables. Univariate analysis revealed that both groups lost a similar amount of weight (WL -2.8±2.1, -5.3±3.4, -5.9±4.4; AG -2.3±1.1, -4.3±2.4, -5.1±3.5 kg, p=0.40) and fat mass loss (WL -2.0±6.1, -2.4±6.4, -4.1±7.8; AG -2.1±5.7, -4.4±5.7, -5.2±6.4 kg, p=0.43) while changes in fat free mass (WL -0.3±5.4, -2.1±5.2, -1.5±5.2; AG -0.3±5.1, 0.3±4.7, 0.2±4.6 kg, p=0.08) and percent body fat (WL -1.0±5.9,

-0.2±6.1, -1.7±6.6; AG-1.5±6.9, -3.9±7.5, -4.5±7.6 %, p=0.07) tended to be more favorable in the AG group. Conclusion Results indicate that experiencing the impact of losing weight on work capacity prior to initiation of an exercise and/or weight loss program has a positive

impact on increasing vigorous activity and changes in body composition. More research is needed to examine whether use of this strategy more often during a weight loss program may affect adherence and/or efficacy of different types of weight loss programs.

“Background Acetate, a short chain fatty acid, is a metabolizableenergy source and may improve buffering capacity during exercise. Study objectives were to assess the effects of consuming beverages containing acetateon maximal anaerobic Baf-A1 solubility dmso capacity, substrate metabolism, and total workoutput during timed endurance exercise. Methods Trained male cyclists (n=11;24.3 ± 0.6 years; VO2MAX:54.9 ± 2.7ml/kg/min)consumed isocaloricsports beverages containing citric acid (placebo), triacetin (TRI), or acetic acid (AA)in a double-blind, randomized, controlled crossover study. Subjects consumed 710 mLbeverage anda standard breakfastbeginning each test day. Subjects performed two 30 second Wingate cycle tests separated by 4 minutes and consumed 7.5 ml/kg beveragewhile resting during a 60-min recovery period.
