Nutrition periodization for action sports -
nutritionist long island. I have read the book and it's very informative. The author speaks about eating when hungry and eating to satiety. When I first started figuring out the nutrition aspect of my training and racing I focused on eating every hours.
I figured that if I was awake from 8am to 8pm that I had 12 hours of eating and needed 4 meals so I did the math and said I needed to eat every 3 hours. I followed this religiously and was eating at times where I wasn't hungry but thought that I needed to eat.

skip to main skip to sidebar Book Review: Nutrition Periodization for Athletes. August 26, This is the kind of reading we love here TheIronYou, as it underscores all the things we believe in. First of all the author points out how the traditional belief that the nutritional element is only important around the time of athletic competition has to be consider old-school and should be left behind in the past, where it belongs.
A variety of training cycles are outlined in the book that at some points sounds almost like a guide accompanied by specific physiological goals such as increasing endurance, speed, strength, and power and improving technique, tactics, and economy.
Covering every sport from football and golf to track and field and martial arts, this book addresses the true needs of athletes who are training and competing on a consistent basis. Nutrition Periodization for Athletes shows you how to gain a competitive edge by using the newest techniques that sports science and research has to offer.
Depending on your sport, your nutrition goals may include losing or gaining weight, decreasing body fat and increasing lean muscle mass, reducing inflammation and free radical production, or improving blood lipids.
This "guide" provides athletes with everything they need to understand the concept and implement it during daily training. Within six chapter the author gives you all the tools to apply the strategy to a variety of sports and no matter what level of athlete you are, the book covers optimal fueling plans for everyone striving for peak health and performance.
Also, the fact that Bob Seehobar also practices what he preaches being an athlete himself makes the whole process much reletable to us TheIronYou where we are our own rat-laboratory. The Iron You You can get a copy of this book at amazon. In order to effectively train, we modulate the intensity, volume, and frequency of our workouts so we show up on race day as fit and rested as possible.
These training changes put different demands on our bodies to elicit specific physiological responses. If the demands on our bodies vary, it follows that our nutrition to fuel our bodies should vary as well. Therefore, understanding nutrition periodization is vital to achieving optimal performance.
The amount needed of each of the three macronutrients: carbohydrate, protein and fat for each phase will vary, not only depending on what training cycle you are in, but also on your sport, individual physiology and performance goals.
Here are some ranges suggested by Bob Seebohar Ref. We see that in competition season the carbohydrate intake increases due to the higher energy demands placed on the body. Protein remains moderate and there is slightly higher fat intake, also to help support the increased energy demands.
We can also think about periodization on a daily basis.
Peripdization link between good health and good nutrition is Nytrition established. Interest in nutrition and its impact on Nutritioj performance spodts now a science in itself. Whether you are pefiodization competing athlete, a weekend sports player or Ideal food groups for sports performance Nutrition periodization for action sports daily exerciser, the aciton to Nutrition periodization for action sports sporst is a nutritionally adequate diet. Athletes who exercise strenuously for more than 60 to 90 minutes every day may need to increase the amount of energy they consume, particularly from carbohydrate sources. The current recommendations for fat intake are for most athletes to follow similar recommendations to those given for the general community, with the preference for fats coming from olive oils, avocado, nuts and seeds. Athletes should also aim to minimise intake of high-fat foods such as biscuits, cakes, pastries, chips and fried foods. After absorption, glucose can be converted into glycogen and stored in the liver and muscle tissue.Athletes should achieve Nutritjon physiological requirements through careful acttion of training, Detoxification Retreats Worldwide by individualized and targeted nutrition strategies.

The available studies are periodizaiton to endurance and team sports athletes who have provided a snapshot of the micro- and meso-periodization of nutrition during training phases Burke et al.
More recently, we completed preliminary work to characterize self-reported approaches to periodization of nutrition over the annual training plan Heikura et al.
Based on our pilot study using a similar survey self-reported approach Heikura et al. Recruitment and completion of the surveys were completed between February 8 and May 21, The Ethics Committee of Australian Catholic University approved the study protocol which conformed to the Declaration of Helsinki.
The survey consisted of an updated version of our pilot study based on our reflections on the responses from the original cohort and additional feedback from colleagues and athletes.
The final version of the survey was built online using SurveyGizmo Boulder, CO, United States. The survey was completed anonymously, and an informed consent a prerequisite for completing the survey was completed as part of the online survey by all participants. The first part of the survey included background information, instructions, and general subject information.
Thereafter, the athlete was asked to choose one of the two annual training periodization programs track [e. road [e.
Part A also included questions on general nutrition principles e. Additionally, parts B, C, and D asked questions on training volume, key session and race frequency as well as number of race peaks. before training. Finally, the survey ended with an open, but optional, comment box.
It is important to note that the survey was purposely constructed to apply to the culture, practices and terminology used in endurance events in track and field. As such it is not directly applicable to other sports, and if used for other populations, even among endurance sports, it will need to be customized to the specific characteristics of these sports.
A sample survey has been provided in the Supplementary Material to this paper. The data were checked and cleaned by excluding duplicate responses i. The answers were classified into clusters for further analysis using groupings based on sex male vs.
femaledistance middle distance MidD;m vs. track distance TrackD; 3, m steeplechase to 10, m vs. Data were first organized using Microsoft Excel, while further statistical analyses were conducted using SPSS Statistics 22 software INM, Armonk, NY, United States. Normality of continuous data was checked with the Shapiro—Wilk goodness-of-fit test.
Chi-square test X 2 for independence with Yates Continuity Correction along with phi effect size statistic were used to test for differences between subgroups. Where more than two subgroups were present, Kruskal—Wallis Test was used as a post hoc test.
In addition to numerical outcomes, relevant quotes provided by athletes in cursive have been embedded in the results section to provide further qualitative insights into the topic in question.
To aid in the interpretation of results from the lengthy survey, aggregation of consistent outcomes across the survey was undertaken by all authors upon visual inspection of figures to develop a series of themes. Fifty-two were classified as high and 52 as lower caliber.
Training volume groupings resulted in 33, 31 and 31 athletes classified as low, moderate and high volume, respectively. It is worth noting that while the difference in training volume was significant between males and females, this difference is likely to disappear if training volume were to be assessed by minutes of total training.
MidD and TrackD athletes showed meso-periodization of training volumes, whereby training volume was significantly less during the competition season compared to the base training phase Table 1.
This variation in training load was absent among RoaD, who reported equal training volumes between base training and preparation for competition. TABLE 1. The results of the survey are summarized in the following figures: Figure 1 Overall dietary practices across the year ; Figure 2 Eating on hard training days ; Figure 3 Eating on easy training days ; Figure 4 Fueling and recovery around key sessions ; Figure 5 Training in the fasted state ; Figure 6 Periodic CHO restriction ; Figure 7 Ingestion of CHO during training ; Figure 8 Major nutrition strategies implemented during competition season or preparation for competition ; Figure 9 Nutrition in the 24—48 h before the race day ; Figure 10 Nutrition on the race day ; Figure 11 Nutrition during the race.

This theme is present in nutrition practices overall Figure 1 , as well as throughout specific micro, meso and macro levels of training and competition Figures 2 — Competition nutrition strategies focused mainly on adequate CHO and fluid intake before Figure 9 and on race day Figures 10 , 11 as well as on low residue diet throughout this time period. A number of athletes further explained their dietary choices, A selection of noteworthy athlete quotes are in Table 2. TABLE 2. Selection of noteworthy athlete quotes regarding why they do, or do not, follow a specific nutrition strategy. This study aimed to characterize self-reported dietary periodization across macro general practices across the annual cycle , meso training and racing phases and micro between- and within-day phases of training and competition in a large cohort of elite female and male middle- and long-distance runners and race walkers. Historically, nutrition guidelines for endurance athletes have focused on strategies to habitually achieve high CHO availability to support performance and recovery around training and races Coyle, Indeed, it seems that this cohort of elite road-distance athletes are aware of, and aim to, follow current sports nutrition guidelines that emphasize optimal CHO intake around key training and racing Thomas et al. On the contrary, and as expected, these strategies were less important for athletes competing in shorter distance events where endogenous CHO fuel stores are not limiting. Meanwhile, more recent studies have focused on the adaptation and performance effects of strategically and periodically implemented low CHO availability before, during, or after exercise Bartlett et al. These studies suggest that occasional and strategic training with low CHO availability increases the cell signaling and gene expression responses that are usually seen after endurance training, thereby leading to further enhanced endurance capacity and performance. Possible strategies, as detailed in a recent commentary of definitions and proposed outcomes Burke et al. While these strategies and their potential outcomes are intriguing, studies in elite athletes have failed to show direct performance benefits Burke et al. Furthermore, studies on bone and iron health suggest these strategies may impair bone and iron metabolism, possibly leading into increased bone breakdown Sale et al. Therefore, careful day-to-day periodization is likely required, where low CHO availability is primarily scheduled around low intensity sessions Hearris et al. A more recent advancement in the field is periodization of body composition Stellingwerff, , which refers to the manipulation of body composition via a mixture of nutrition and training strategies for optimal health and performance. The underlying idea is that race weight should not be maintained year-round, as this is likely to require chronic periods of low energy availability EA and its related impairments of several health and performance related measures Mountjoy et al. Therefore, EA may need to be periodized across the year, with emphasis on higher EA levels during heavy training and altitude camps, and lower EA during lower training volumes and closer to the competition season. In addition to this macro and meso periodization of EA, emerging evidence suggests that within-day EA micro level periodization has also significant health consequences Deutz et al. In the current study, middle-distance athletes reported more attention to the effects of nutrition strategies on physique outcomes; however, their chief focus was to build and maintain lean mass. Females and males have an equal ability for CHO storage and utilization during exercise if energy availability is adequate Tarnopolsky et al. However, female distance athletes tend to eat less CHO than males Burke et al. Indeed, females are more likely to suffer from eating disorders Sundgot-Borgen and Torstveit, Namely, male athletes were more likely to follow a chronically high CHO diet Figure 1. Males were also more likely to follow a high energy diet in the acute time period preceding the race day Figure 9. Contrary to previous guidelines Coyle, , more recent sports nutrition guidelines have incorporated the value of specialized strategies to optimize adaptations to training, noting that these protocols may often be contradictory for acute performance outcomes or other health goals, and need to be carefully integrated into the various phases of the annual plan Thomas et al. We were interested to identify whether these concepts were understood by elite athletes and used to inform their various nutrition strategies. Meanwhile less was known about specific strategies to further stimulate cellular adaptations to exercise Figures 5 , 6. Indeed, many athletes lacked understanding of the periodization of strategies to train with low CHO availability, furthermore, others were either skeptical of their value, concerned about perceived or actual disadvantages particularly related to illness or injury, or practicing some aspects within their routines by accident. It is important to note that the current study describes self-reported nutrition practices that are implemented across the training and competition year. We have previously shown that there is a discrepancy between general descriptions of practices reflecting a macrocycle and actual self-recorded intakes collected across a micro cycle in elite distance athletes Heikura et al. Indeed, it is possible that self-reports such as those found in the current study, reflect either what athletes aspire to achieve or perceive that they follow rather than actual behaviors. However, this potentially perceived versus actual mismatch would hypothetically be equivalent across the various sub-groups of athletes. Furthermore, our survey questions were qualitative i. Nevertheless, our survey was based on the learnings from a pilot study Heikura et al. Our key findings suggest that: 1 Road athletes train with both low and high CHO availability within the annual training plan, while track athletes are less likely to incorporate a large spectrum of CHO availability in their training; 2 Middle-distance athletes emphasize physique when choosing a nutrition strategy; and 3 Performance appears to be the key driving factor influencing nutrition choices, while themes such as body composition manipulation, health, and practicality are less important. Overall, our findings indicate that elite track and field distance athletes are aware of and report following the current sports nutrition guidelines in terms of high CHO availability around key training sessions and during racing. This is a survey study which participants completed via an online survey tool. Consent to participate was completed via ticking in a box. The participants who proceeded to complete the survey were thus seen as consenting to participate in research. IH, TS, and LB designed the study, developed the survey, recruited the participants, and prepared the manuscript. IH collected, organized, and analyzed the data. All authors approved the final manuscript. The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.
