The 3.5% cocoa beverage showed a larger effect

for LDH (85% return versus 78% return to baseline for the other 3 beverages) and the 3.5% cocoa beverage and placebo showed a larger effect for CPK as compared to the CES and 6% cocoa beverage although these differences were not statistically significant. Conclusion The addition of cocoa to www.selleckchem.com/products/oicr-9429.html CHO-PRO beverages may offer an exercise performance advantage over CHO-PRO beverages without cocoa and CHO-electrolyte solutions. This clinical trial found that a 3.5% cocoa CHO-PRO beverage demonstrated significant performance enhancement effects as compared to placebo and a leading sports beverage. Additional studies are warranted to fully explore the potential ergogenic effects of the 3.5% cocoa beverage.

“Background To investigate the potential effects in males on body composition, muscular strength, and hormones of a proprietary tribulus fruit extract and vitamin/mineral blend in combination with a resistance training program. Methods Twenty-eight (22±4.48 yrs, 179.22±9.04 cm, 83.41±11.95 kg, 15.90±5.07 %BF) resistance-trained males between the ages of 18 and 30 were

randomly assigned by body weight to ingest either a placebo or tribulus blend (tribulus fruit extract-40% saponins) in a double-blind manner. Subjects participated in a supervised 4-day per week periodized resistance training program split into two upper and two lower extremity workout per week. At baseline (T1), 4 weeks (T2), and 8 weeks (T3), body composition (DEXA),

muscular strength (1RM), muscular endurance, and anaerobic power measurements (Wingate) were determined. Venous blood samples were obtained using standard procedures Thiamet G at all time points. Blood analyses included serum and whole blood metabolic profile and the serum analysis of free testosterone, cortisol, and insulin were conducted using standard EIA and ELISA assay protocols. Statistical analyses utilized a two-way ANOVA with repeated measures for all dependent variables (p < 0.05). Results Significant main effects for time (p = 0.001) were observed for the dependent variables bench press 1RM (T1: 106.10±16.41 to T3: 112.91±22.23 kg), leg press 1RM (T1: 333.73±57.36 to T3: 441.5±52.59 kg), and lean muscle mass (T1: 66.23±9.23 to T3: 67.08±9.19 kg) indicating that the resistance training protocol resulted in significant adaptations. However, no significant interactions were observed on the measures of strength and body composition (p > 0.05) indicating that supplementation had no additional benefit. A significant main effect for time was observed for serum insulin (p = 0.01), however there was no significant differences between groups. No significant main effects or interactions (p > 0.
