The investigators postulated that this may be due to an increased delivery of amino acids to the leg [29]. Clearly, issues related to blood flow would not be advantageous to the POST-SUPP group in the current study. Another study investigated the importance of immediate (P0) or delayed (P2: 2 hours post exercise) intake of an oral protein supplement upon muscle hypertrophy and strength www.selleckchem.com/products/Vorinostat-saha.html over a period of resistance training in elderly males. In response to training, the cross-sectional area of the quadriceps femoris muscle and mean fiber area increased in the P0 group, whereas no significant increase was observed in P2. These investigators found no difference in the glucose or
insulin response at P0 or P2, thus, it is not likely that differences in the hormonal environment contributed to the difference in muscle mass gain. Thus, the early intake of an oral protein supplement after resistance training is important for skeletal muscle hypertrophy [42]. Perhaps the seminal study vis a vis nutrient timing compared taking a protein-carbohydrate-creatine supplement either immediately pre and Androgen Receptor Antagonist post exercise (PRE-POST) or in the morning and evening (MOR-EVE). Indeed the PRE-POST group demonstrated
a greater increase in lean body mass and 1-RM strength in two of three assessments. Furthermore, type II muscle fiber cross-sectional area was larger in the PRE-POST group as well as intramuscular concentrations of creatine and glycogen [25]. Data from this investigation showed the intramuscular creatine and glycogen concentrations were greater in the
PRE-POST versus MOR-EVE groups. Thus, taking the exact same supplement (but timed pre and post exercise) is significantly better than consuming it in the morning and evening. Our investigation did not involve the use of protein, carbohydrate or amino acids. Whether creatine uptake is truly sensitive to timed intake is not entirely known despite the superior gains in the POST-SUPP group. Moreover, it is entirely possible that the difference Buspirone HCl in body composition and muscular strength between the two groups was the result of a small sample size. One individual in the POST-SUPP and three individuals in the PRE-SUPP group experienced a minor reduction in FFM. With regards to 1-RM bench press performance, two subjects in the PRE-SUPP group showed either no change or a decline in strength; on the other hand, only one subject in the POST-SUPP group showed no change in strength. All other subjects experienced an increase in strength. The use of recreational bodybuilders in the current investigation is advantageous because it is difficult for highly trained individuals to experience an increase in FFM or muscular strength in the time frame allotted for this study. Nonetheless, of the 19 subjects that completed the study, 16-21% were non-responders regarding muscular strength and FFM.
