Methods 10 players (age 26.7 ± 3.) were evaluated throughout the championship. Fat-Free Mass and Fat Mass were assessed with DXA (Lunar iDXA, GE Healthcare). In the same time resistance and reactance components of impedance vector (Z vector) at 50

kHz frequency (BIA 101 RJL, Akern Italy) have been recorded. Measurements were performed at the beginning (T0) and at the end (T1) of the preseason training, therefore at mid (T2) and at the end (T3) MK-1775 order of the regular season. During that period, athletes shared the same nutrition and supplementation programs. Results From T0 to T1, FFM relative values increased significantly (82.2 ± 2.4% vs 85.1 ± 2.4% p<0.05) while FM% decreased considerably (13.8 ± 2.8% vs 10.8 ± 2.5%, p=0.55). Both values maintained steady during the rest of the season.

Weight and BMI did not show significant changes during the whole period (p>0.05). Mean impedance vector placement differed significantly (Hotelling T2 test, p < 0.001), showing body water expansion and reduction respectively in T1 (compared to T0) and in T3 (compared to T1 and T2). Discussion During the competitive season, athletes tested with both BIVA/iDXA techniques showed, as expected, an improvement of quantitative parameters of BC (Fat-Free Saracatinib in vivo Mass and Fat Mass) during the preseason period, and remaining almost unchanged during the rest of the season. However, parallel BIVA measurements show that early improvements of FFM/FM ratio were due to a mere fluid expansion, rather than a real change in muscle or lipid amount as DXA could wrongly display. In contrast, a sharp decrease of water compartment during the final stage of the season, against the same amount of Fat-Free Mass, during early- and mid-season period, suggests a possible improvement of muscle tissues during competitive season that DXA did not detect. Conclusion According to our data, we found that DXA technique is not adequate to discriminate variations of the Fat-Free Mass protein/cellular and hydration components. We suggest therefore to complete soft tissues assessment with BIVA technique. DXA / BIVA methods should be considered as complementary, not

alternative.”
“Background The prevalence of overweight and obesity worldwide has resulted in the growth of over the counter weight loss products into one the largest categories of nutritional supplements. However, few commercial Liothyronine Sodium products have been properly examined in finished commercial form and seldom have been studied in comparison with individual active ingredients. The purpose of this study was to investigate the acute effects of the commercial weight loss/energy product, Fastin-XR® (High-Tech Pharmaceuticals, Inc., Norcross, GA) on measures of metabolic and hemodynamic activity in comparison with the effects of caffeine and the effects of acacia rigidula. Methods Ten recreationally active men, 28.5 ± 5 years of age, voluntarily participated in this investigation.
