However, IMT stores vary considerably in humans, in part as a function of training status, muscle fiber type, insulin sensitivity, gender, and diet . Eur J Transl Myol.

Many competitive organizations include multiple judging rounds [200,201,202] and categories such that the competition may transpire over the course of an entire day (or longer). doi:https://doi.org/10.1007/s00394-004-0453-7. doi:https://doi.org/10.1123/ijsn.8.4.345. 2010;24:107481. Further, in addition to the medical risks noted previously, the ill-advised use of pharmacological diuretics during peak week may likely disrupt fluid homeostasis and diminish the reliability and thus success of diuretic strategies employed over a series of competitions in close temporal proximity. doi:https://doi.org/10.1001/archinte.1939.00180200100008. Meal #1: Breakfast around 7am. For the most part, you wont be drinking much water, but again keep your body in front of the mirror to determine this. An observational study gathered information on nutritional peak week and competition day strategies among 81 natural bodybuilders (Males=59, Females=22) via a 34-item questionnaire; the survey listed commonly utilized peaking strategies and provided additional space for qualitative information . At age 62, "Big Bill" shares his wisdom to dominate one of the ultimate strength marks. doi:https://doi.org/10.1172/JCI107410. BMC Sports Sci Med Rehabil 13, 68 (2021). This is a term that comes from competitive bodybuilding. In addition, photos of the competitors taken at these time points were shown to a group of federated bodybuilding judges, who subjectively assessed their physiques; of note, judges were blinded to the competitors nutritional practices. Protein only (shake with very little water). Int J Sports Physiol Perform. This temporal lag in establishing fluid and electrolyte homeostasis, if timed correctly, may be implemented to induce diuresis before the protective homeostatic mechanisms fully manifest to halt water loss. Physique peaking and manipulating hydration is easy to screw up. Water is also a natural diuretic. However, it seems prudent that athletes do not experiment during peak week with new CHO, protein sources, or other supplements not integral to peak week specific strategies to reduce the risk of experiencing negative gastrointestinal symptoms or any other deleterious consequences. This may require competitors to maintain strict dietary control and rapidly establish fluid homeostasis post-competition so as to restore the baseline starting conditions (e.g., muscle glycogen levels) upon which a given peak week strategy may rely. The potential for glycogen loading to impair IMT storage suggests that separating periods of glycogen and fat loading may be prudent, with a high CHO diet preceding efforts to fat load . During a depletion/supercompensation resistance exercise protocol, resistance exercise should engage all major muscle groups and employ a variety of exercises to ensure widespread reduction in IMT and glycogen levels across the entire muscle mass. https://ssms.ch/fileadmin/user_upload/Zeitschrift/51-2003-1/07-2003-1.pdf. Bodybuilders try cutting sodium during peak week, as they wrongly believe that it will help them flush water from their bodies. J Physiol. For example, you may need two days to carb-up. , who tracked the body composition and hormonal profile of national and international level bodybuilders during the final 11 weeks of contest preparation. Training legs first in this series of peak week workouts allows the greatest time for recovery in these muscle groups. reported that 39% of males and 47% of females consumed an omega-3 supplement (e.g. Similarly, different approaches might need to be implemented by athletes competing in the various subdivisions of bodybuilding (i.e., womens physique/figure/wellness/bikini/fitness and mens physique/classic physique) where judging standards may differ from those of traditional bodybuilding. Bodybuilders manipulate their water and carb intake to get rid of water weight. Recently, members from our group (Schoenfeld and Escalante) carried out a case study where we followed a high-level natural bodybuilder over the course of his contest preparation . Bamman MM, Hunter GR, Newton LE, Roney RK, Khaled MA. Graham TE, Yuan Z, Hill AK, Wilson RJ. Water and sodium are frequently manipulated by bodybuilders, either independently or concurrently, employing a variety of strategies involving loading and restricting both , with the goal of minimizing subcutaneous water to maximize the underlying skeletal muscle definition [8, 11, 12, 14, 19, 20]. Rather than introducing new foods, consuming mainly the same dietary constituents during peak week as those consumed during the preceding weeks/months beforehand may also be helpful in avoiding gastric distress. Ten days before the show, Ill bump up their water an additional 34 to 1 gallon per day. within a 10h window) ; however, to our knowledge, no research has directly examined its impact on intracellular vs. extracellular fluid shifts or on its effectiveness during peak week. 1995. 19.95. Effects of diet on muscle triglyceride and endurance performance. The best approach is to suddenly cut your water so that your body stays in flushing mode even when no water is coming in.

Don't let these innocent things get in the way of your fitness progress this holiday season. In another study, investigators reduced sodium intake to extremely low levels (10 meq/day) for ~6 days in 16 healthy men and measured the RAAS, plasma aldosterone, urine sodium, and serum sodium levels at 24h, 48h, and ~6 days after the intervention . The latter study was conducted by Mestu et al. If you pump up too much, youll be bigger, but lose definition, minimising the effect of the hard work youve done to get to this stage.

Based on these principles of water-electrolyte balance and the current evidence available, it appears that the manipulation of water and sodium should be carefully considered, planned, and practiced in conjunction with carbohydrate manipulation if they are to be utilized. Kleiner SM, Bazzarre TL, Litchford MD. Why? Effect of creatine supplementation on body composition and performance: a meta-analysis. Twenty-four high-level amateur male bodybuilders were stratified based on whether or not they manipulated carbohydrate as a peaking strategy; the group that manipulated carbohydrate employed a three day depletion phase (leading immediately up to the weigh-in day) followed by a 24-hour loading phase (leading up to competition day). 1996;271:E8216. doi:https://doi.org/10.1123/ijsnem.20.5.427. 1999;277:R144452. Int J Sport Nutr Exerc Metab. Although substantial data in many population demographics supports the use of EPA & DHA as a means to reduce systemic inflammation and improve insulin sensitivity [140, 141], it remains unknown if this can enhance the peaking process. Given the complicated interplay of physiological variables during peak week, as well as biological inter-individuality and variability in the importance placed on maximizing various aspects of muscularity across the different competitive divisions, there are a multitude of research avenues for investigating peak week strategies. That would be a disaster. Since fruit and fructose sources of carbohydrates better stimulate liver glycogen restoration, whereas glucose does so for muscle glycogen , it is recommended that the majority of the carbohydrates consumed come from starchy/glucose-based sources. 2017;147:8507.

Evidence suggests that bodybuilders frequently use peak week strategies such as CHO loading, water/sodium manipulation, and other approaches in an attempt to enhance their physique during their last week of competition preparation.
