Muscular endurance was determined by performance of three sets of bench press and three sets of barbell curls with bodyweight and 1/3 bodyweight, respectively, with one minute AUY-922 solubility dmso recovery periods between sets. Work volume was calculated as repetitions completed times resistance utilized with work volume and reps completed examined per each set completed and as total values for bench press and barbell curls. Pre- and post-supplementation values of all variables were standardized into change scores relative to baseline values. Statistical analyses were conducted using one-way ANOVAs with the accepted level of significance

set at p < 0.05. Results Results indicated that while AD produced a mean increase of hematocrit from

43.67% to 45.83% and PL did not change (pre and post = 43.83%) these differences within and between groups were not statistically significant. Bench press repetitions change scores for the three sets were (+3.0, +1.3, +1.0) for AD and (+1.7, -0.7, -0.2) with PL. No significant differences were detected between conditions for reps completed or total work volume per set. However, the increase in total bench reps completed with AD (+5.3) was statistically greater than with PL (+0.8) (p=0.05) and the total bench press work volume change scores were also statistically different between conditions (AD=+883.3; PL=+212.5 rep lbs). Mean change scores for the three sets of barbell curls were (+2.8, +4.2, +4.0) with AD were not significantly different from PL (+0.8, +2.6, +0.7) with no significant differences detected PARP phosphorylation ADAMTS5 between conditions in work volume per set (p’s>0.05). While not statistically significant, AD produced a mean increase

of 11.0 total BC reps compared with 4.0 reps increase with PL. Conclusion These findings indicate that upper extremity muscular endurance is significantly enhanced with Adenoflex®. This may indicate an improved training stimulus for muscular endurance and/or for muscular hypertrophy.

“Background Popular sports supplements contain a number of ingredients claiming to increase performance and enhance muscle gain. Product specific research is important for identifying efficacy of combined ingredients. The purpose of this study was to evaluate the effects of the proprietary pre-workout dietary supplement Dymatize XPAND, containing Creatine, CarnoSyn® Beta-Alanine, vitamins, L-Tarurine, L-Leucine, micronized pure and caffeine, on anaerobic power, muscular strength and endurance, body composition, as well as subjective measures of alertness, focus, energy, concentration, and hunger. Methods In a double-blind, randomized ,matched -pair design, 12 males subjects (n = 12,mean ± SD; 22.4 ± 9.5 yrs, 171.3 ± 11.2 cm, 76.9 ± 11.2 kg, 22.7 ± 9.
