Relative to any supplement-induced differences in exercise performance, VO2max assessed at each of the testing sessions demonstrated no significant differences between Meltdown and placebo (45.31 ± 6.10 vs. 41.69 ± 9.98 ml O2/kg/min, p = 0.185). Meltdown increased REE significantly more than placebo at 45 min (1.44 ± 0.25 vs. 1.28 ± 0.23 kcal/min; p = 0.003) and 60 min (1.49 ± 0.28 vs. 1.30 ± 0.22 kcal/min; p = 0.025) post-ingestion. Furthermore, REE 60 min post-exercise (120 min following supplement administration) was significantly higher in the Meltdown group (1.51 ± 0.26 vs. 1.33 ± 0.27 kcals/min; p = 0.014) (Figure ​(Figure1).1). Over the course of the evaluation period, AUC analysis demonstrated that REE was significantly increased with Meltdown compared to placebo (992.5 ± 133.1 vs. 895.1 ± 296.1 kcals; p = 0.043) (Figure ​(Figure22). ]]> Thu, 10 May 2012 03:46:11 -0500 http://fitmarker.com/supplementation/the-acute-effects-of-the-thermogenic-supplement-meltdown-on-energy-expenditure-fat-oxidation-and-hemodynamic-responses-in-young-healthy-males/ http://fitmarker.com/supplementation/beta-alanine-supplementation-augments-muscle-carnosine-content-and-attenuates-fatigue-during-repeated-isokinetic-contraction-bouts-in-trained-sprinters/ Wed, 09 May 2012 14:34:08 -0500 http://fitmarker.com/supplementation/beta-alanine-supplementation-augments-muscle-carnosine-content-and-attenuates-fatigue-during-repeated-isokinetic-contraction-bouts-in-trained-sprinters/ http://fitmarker.com/supplementation/protein-ingestion-prior-to-sleep-improves-post-exercise-overnight-recovery/ Wed, 09 May 2012 04:15:13 -0500 http://fitmarker.com/supplementation/protein-ingestion-prior-to-sleep-improves-post-exercise-overnight-recovery/ http://fitmarker.com/supplementation/placebos-are-getting-more-effective-drugmakers-are-desperate-to-know-why/ Tue, 08 May 2012 23:31:06 -0500 http://fitmarker.com/supplementation/placebos-are-getting-more-effective-drugmakers-are-desperate-to-know-why/ http://fitmarker.com/supplementation/acute-l-arginine-alpha-ketoglutarate-supplementation-fails-to-improve-muscular-performance-in-resistance-trained-and-untrained-men/ Fri, 20 Apr 2012 03:13:32 -0500 http://fitmarker.com/supplementation/acute-l-arginine-alpha-ketoglutarate-supplementation-fails-to-improve-muscular-performance-in-resistance-trained-and-untrained-men/ http://fitmarker.com/supplementation/dietary-supplements-for-improving-body-composition-where-is-the-evidence/ Abstract Weight-loss supplements typically fall into 1 of 4 categories depending on their hypothesized mechanism of action: products that block the absorption of fat or carbohydrate, stimulants that increase thermogenesis, products that change metabolism and improve body composition, and products that suppress appetite or give a sense of fullness. Each category is reviewed, and an overview of the current science related to their effectiveness is presented. While some weight-loss supplements produce modest effects (<2 kg weight loss), many have either no or few randomized clinical trials examining their effectiveness. A number of factors confound research results associated with the efficacy of weight-loss supplements, such as small sample sizes, short intervention periods, little or no follow-up, and whether the supplement is given in combination with an energy-restricted diet or increased exercise expenditure. There is no strong research evidence indicating that a specific supplement will produce significant weight loss (>2 kg), especially in the long term. Some foods or supplements such as green tea, fiber, and calcium supplements or dairy products may complement a healthy lifestyle to produce small weight losses or prevent weight gain over time. Weight-loss supplements containing metabolic stimulants (e.g., caffeine, ephedra, synephrine) are most likely to produce adverse side effects and should be avoided. ]]> Mon, 09 Apr 2012 09:28:20 -0500 http://fitmarker.com/supplementation/dietary-supplements-for-improving-body-composition-where-is-the-evidence/ http://fitmarker.com/supplementation/the-facts-on-waxy-maize-vitargo-and-other-carbs/ Thu, 23 Feb 2012 12:46:29 -0600 http://fitmarker.com/supplementation/the-facts-on-waxy-maize-vitargo-and-other-carbs/ http://fitmarker.com/supplementation/fitnessnahrung-nicht-nur-fur-bodybuilder/ Mon, 10 Oct 2011 09:38:12 -0500 http://fitmarker.com/supplementation/fitnessnahrung-nicht-nur-fur-bodybuilder/ http://fitmarker.com/supplementation/of-super-nerds-and-supplements-why-you-dont-need-a-bunch-of-supplements-for-health/ Tue, 04 Oct 2011 04:57:28 -0500 http://fitmarker.com/supplementation/of-super-nerds-and-supplements-why-you-dont-need-a-bunch-of-supplements-for-health/
