Is there a link to the data? The averages are one thing, but I`d like to see how many people made up that average, and the variation of those numbers for people who placed.

Nutritional strategies of high level natural bodybuilders during competition preparation

Journal of the International Society of Sports Nutrition 2018 15:4
Abstract
Background
Competitive bodybuilders employ a combination of resistance training, cardiovascular exercise, calorie reduction, supplementation regimes and peaking strategies in order to lose fat mass and maintain fat free mass. Although recommendations exist for contest preparation, applied research is limited and data on the contest preparation regimes of bodybuilders are restricted to case studies or small cohorts. Moreover, the influence of different nutritional strategies on competitive outcome is unknown.
Methods
Fifty-one competitors (35 male and 16 female) volunteered to take part in this project. The British Natural Bodybuilding Federation (BNBF) runs an annual national competition for high level bodybuilders; competitors must qualify by winning at a qualifying events or may be invited at the judge’s discretion. Competitors are subject to stringent drug testing and have to undergo a polygraph test. Study of this cohort provides an opportunity to examine the dietary practices of high level natural bodybuilders. We report the results of a cross-sectional study of bodybuilders competing at the BNBF finals. Volunteers completed a 34-item questionnaire assessing diet at three time points. At each time point participants recorded food intake over a 24-h period in grams and/or portions. Competitors were categorised according to contest placing. A “placed” competitor finished in the top 5, and a “Non-placed” (DNP) competitor finished outside the top 5. Nutrient analysis was performed using Nutritics software. Repeated measures ANOVA and effect sizes (Cohen’s d) were used to test if nutrient intake changed over time and if placing was associated with intake.
Results
Mean preparation time for a competitor was 22 ± 9 weeks. Nutrient intake of bodybuilders reflected a high-protein, high-carbohydrate, low-fat diet. Total carbohydrate, protein and fat intakes decreased over time in both male and female cohorts (P < 0.05). Placed male competitors had a greater carbohydrate intake at the start of contest preparation (5.1 vs 3.7 g/kg BW) than DNP competitors (d = 1.02, 95% CI [0.22, 1.80]).
Conclusions
Greater carbohydrate intake in the placed competitors could theoretically have contributed towards greater maintenance of muscle mass during competition preparation compared to DNP competitors. These findings require corroboration, but will likely be of interest to bodybuilders and coaches.
Peak week strategies of bodybuilders
Hi all, I thought I'd share with you my latest research article on peaking for bodybuilding competitions which was published this morning. In this research I documented the dietary approach to peaking employed by 81 natural bodybuilders and quantified the most prevalent strategies utilised. I then discuss the mechanisms by which these peaking strategies might influence a competitors appearance. Follow the link to read the full text: https://www.mdpi.com/2075-4663/6/4/126
I hope you enjoy it, if you have any thoughts about the research or you'd like to share your own experiences I'd be interested in hearing them.
Abstract:
Bodybuilders utilize peaking strategies in a bid to fine-tune their aesthetics for competition day. The most prevalent peaking strategies utilized by natural bodybuilders are unreported in the current literature. Eighty-one (M-59, F-22) natural bodybuilders were recruited from competitions during the 2016 and 2017 British Natural Bodybuilder Federation seasons. Competitors completed a 34-item questionnaire designed to investigate peaking and contest day strategies. The questionnaire listed commonly utilized peaking strategies and provided additional space for qualitative information. Analysis of the data indicated that carbohydrate (CHO), water, and sodium manipulation were the most commonly utilized peaking strategies. The consumption of high glycemic index CHO was the most common competition day strategy. Only 6.2% of competitors reported following their regular diet the week prior to competition. The CHO manipulation strategies followed were similar to classical CHO loading, whereby bodybuilders attempt to maximize muscle glycogen concentrations. Furthermore, bodybuilders attempted to remove superfluous water by exploiting the diuretic/polyuria effect associated with water loading/restriction. The potentially deleterious effects of peaking on bodybuilders’ health is considered and the efficacy of these strategies to enhance appearance is discussed. The findings of the present investigation are likely to be of interest to bodybuilders and their coaches.

So if I allocated my macros and energy expenditure precisely to those top 5 competitors I'll have a pretty good chance of winning a show?
I know nut'n about competing, tho this takes all the guess work out. How simple is that!!
Awesome :headbang:
Unfortunately the study really is 100% useless.
Higher carbohydrate intake during contest prep is either superior, inferior, or there is no difference. We cannot infer anything from the study about which of the 3 hypotheses is correct.
This is because the study only compares the unconditional means of competitors who place and those that don't. They do not take into account the myriad of other factors that influence placing and which are correlated with carbohydrate intake.
As buck points out, they could have controlled for some of the confounding variables like training, cardio. etc. in a regression analysis.
But even if they did that, there would still be omitted variable bias in the coefficient estimate of carb intake. This is because there are unobserved/observable characteristics of competitors that cannot be controlled for. For example, people with higher genetic potential for muscle building may also have a faster metabolism and thus consume more calories/carbs. Those who are more motivated may stick more to the diet/supplement regime and not skip meals, and they also may do so for their training plans, posing practice etc. There's an endless list of such potential confounders.
This is exactly why researchers go through the lengths of setting up experiments. It's the only way to draw causal inference. Crap studies like this one are not only useless, but actually counterproductive, since laypersons will draw the wrong conclusions from them.

It's funny how people make up stuff and other people believe it.
