Nutritional periodization for runners -
Intuitively, train-low may be best left to those training sessions that are not as CHO dependent and where the intensity and duration is not likely to be compromised by reduced CHO availability e. As with all nutritional strategies, application of CHO periodization should only be done in conjunction with appropriately qualified nutrition professionals and be continually refined and optimized.
Although endurance-trained athletes have an enhanced capacity for fat oxidation compared with untrained, this adaptation is clearly not maximized from training alone as it can be doubled, or even tripled, by chronic adaptation to a LCHF diet Burke et al.
However, studies have shown that as little as 5 days of exposure to HFLC diets, while continuing to undertake both high volume and intensity of training, achieves a robust retooling of the muscle to increase intramuscular triglycerides stores, and enhance the mobilization, transport, uptake, and oxidation of fats for review see Burke, By itself, however, chronic adaptation to a NK-LCHF does not translate into clear improvements in endurance performance, except in specific scenarios or individuals Burke, Therefore, a microperiodization protocol which theoretically could sequentially enhance the capacity of both fat- and CHO-based fuel oxidation prior to an endurance event has been proposed; this involves a 5—6 days fat adaptation phase followed by acute restoration of CHO availability just prior to and during the endurance task Burke et al.
Investigation of this protocol showed that the muscle retooling achieved by the fat-adaptation phase is robust in continuing to promote higher rates of fat oxidation in the face of aggressive strategies to restore high CHO availability during the endurance task Burke et al.
Despite substantially reduced rates of muscle glycogen utilization during the early part of the exercise task, there was no clear enhancement of a subsequent time trial in any of these studies. One apparent explanation for this outcome is that, rather than sparing glycogen utilization, chronic exposure to a high-fat diet causes an impairment of CHO oxidation during exercise due to a reduction on glycogenolysis and a downregulation of the activity of the pyruvate dehydrogenase complex [PDH; Stellingwerff et al.
Data from rodent models suggests that such inhibition of PDH activity may actually be due to the effects of reduced muscle glycogen availability.
Indeed, commencing exercise with reduced muscle glycogen augments the activation of peroxisome proliferator-activated receptor-δ PPAR-δ; Philp et al.
In human muscle, however, we have recently shown that the downregulation of CHO metabolism appears to be a consequence of the high-fat diet and increased fat availability rather than CHO restriction alone Leckey et al.
The consequences of reduced CHO utilization within the tricarboxylic acid cycle are likely to manifest in a reduced capacity for ATP production at high intensities. The proposed benefits of chronic adaptation to ketogenic LCHF diets has also received recent attention in both the lay Brukner, and the scientific press Noakes et al.
However, Phinney et al. already noted that this feat was achieved in the face of impairments of capacity to undertake exercise at higher intensities. A more recent investigation of 3.
In this study, some of the highest rates for fat oxidation ever reported in the literature were achieved following adaptation to the K-LCHF diet, under conditions of either fasting or intake of fat during a prolonged exercise protocol.
However, this was associated with an increase in the oxygen cost i. Taken together, chronic LCHF interventions have been shown to a decrease CHO oxidation Burke et al. This would decrease the effectiveness of CHO feeding strategies, thus increasing the risk of gut disturbances Jeukendrup, b.
It is important that coaches and athletes understand the metabolic demands and limiting factors in their events Figure 1 , and trial-specific interventions on an individual level Figure 3 , and realize that all sustained majority of track and field events are exceptionally CHO dependent.
The numerous various events in athletics, all with unique bioenergetics, biomechanical, and structural performance determinants, lend themselves to endless permutations of potential periodized nutrition interventions.
Therefore, this review took a holistic approach to develop a nutrition periodization framework to guide practitioners in the field across these nutrition periodization options, while grounding them in targeted intervention first principles Figure 1 and Table 1.
From this framework, the literature has been examined regarding macro-, meso-, and microperiodization of CHO availability, and consequently, fat periodization Table 2 and Figure 2 , with considerations and recommendations to individualize and test in the field, as required Figure 3.
However, Figure 1 highlights various other nutrition examples of periodization that are beyond the scope of this review, but we would highlight a few other papers in this series that also feature periodized nutrition examples for protein Witard et al.
With an appreciation of the complexities of training periodization, future directions in this field should include better quantification of knowledge and application of existing periodized approaches in elite athletes, as well as systematically controlled CHO periodization approaches over prolonged training blocks in larger cohorts of athletes.
In summary, the field of periodized nutrition has made considerable gains over the last decade, but is ripe for further progress. Akerstrom , T. Biochemical and Biophysical Research Communications, 3 , — PubMed ID: doi Areta , J.

Many pragmatic questions remain unanswered and another goal of this review is to identify some of the remaining questions that may have great practical relevance and should be the focus of future research.
Abstract It is becoming increasingly clear that adaptations, initiated by exercise, can be amplified or reduced by nutrition. Publication types Review. Overall, your diet should include foods that provide a lot of beneficial nutrients like protein, fiber, vitamins and minerals.
Consider using some of your free time to cook a new recipe or take a trip to the grocery store to find a few new foods to try. No matter what phase you are in, eating a balanced diet that includes a variety of foods from each food group is key.
You will need carbohydrate-rich foods to provide the energy needed to support your intense workouts. Choose a variety of complex carbohydrates like breads, pasta, and rice, as well as fruits and vegetables to provide your body with vitamins and minerals. Protein rich foods support muscle repair and recovery.
Dairy products provide a great source of both calcium and protein, which are two nutrients important for student athletes. Other high-quality protein options are meat, poultry, beans and eggs. If you need help creating a customized nutrition plan to support you through all the phases of your training, a registered dietitian nutritionist can help.

Nutrition-related contributors include body mass and anthropometry, capacity to use periodizaiton, particularly carbohydrate CHO to produce adenosine triphosphate economically over runnesr duration of the event, and maintenance of reasonable hydration status in the face of sweat losses induced by exercise intensity and the environment. Race nutrition strategies include CHO-rich eating in the hours per days prior to the event to store glycogen in amounts sufficient for event fuel needs, and in some cases, in-race consumption of CHO and fluid to offset event losses. A personalized and practiced race nutrition plan should balance the benefits of fluid and CHO consumed within practical opportunities, against the time, cost, and risk of gut discomfort. In hot environments, prerace hyperhydration or cooling strategies may provide a small but useful offset to the accrued thermal challenge and fluid deficit.

Nevertheless, with varying levels of evidence, sport and event specific sequencing of various training units and sessions long [macrocycle; months], medium [mesocycle; weeks], and short [microcycle; days and within-day duration] is a routine approach to training periodization. Indeed, implementation of strategic temporal nutrition interventions macro, meso, and micro can support and enhance training prescription and adaptation, as well as acute event specific performance.Nutritional periodization for runners -
The work is done, we just need to follow our pre-race and race day nutrition plans and watch our nutrition training from the past cycles pay off. There are a few things you can do nutritionally during this cycle that will have an impact on your performance.
After a successful track season or a new marathon PR, it is time for some much needed rest and recovery. Your body may need weeks of absolute rest with minimal running or working out after a long and intense race like the marathon or an Ironman, or even after many weeks of back-to-back track races.
The transition cycle may last another weeks depending on the start of your next season. It is important to let your body recover to avoid injury, or perhaps to heal an injury that occurred during an earlier cycle.
At the same time, you want to try to maintain a base level of aerobic conditioning for when you are ready to transition back into the preparation cycle. Since the volume and intensity of training are lower at this time than during any other cycle, the biggest concern is unwanted weight gain.
If you do not decrease caloric intake to match your decrease in training, weight gain will likely occur. The end of a long and hopefully successful season is often a time of celebration. You deserve to treat yourself as much as you deserve a break from training.
Just remember to practice some judgment and moderation in your nutrition choices. The following are some basic guidelines for transition cycle nutrition:.
If you had been restricting certain foods or food groups during training and racing, now would be a good time to reintroduce those foods to your diet.
Finally, as in the preparation cycle, try new foods and add some nutritional variety to your diet. Plus, get a breakdown of how many calories you need to eat including how many carbs, proteins and fats you should target to lose weight.

Consideration of any nutrition ergogenic aids that synergistically match the mesoperiodization. What are EA requirements of this mesophase? If a competition block many competitions over several days to weeks , what are the chronic to acute recovery requirements?
During heavy competition phases, extensive logistical planning and practice is required for general, competition, and recovery nutrition interventions. What environmental training interventions are being implemented in this phase? Environments heat, cold, and altitude dictate implementation of various periodized nutrition interventions e.
Consideration of any nutrition ergogenic aids that synergistically match the microperiodization. What are the EA requirements of various different types of training days? Ensure adequate EI for optimal EA, appreciating that there may be day-to-day EEE and EI variability. What is the typical training day schedule?
What are the acute recovery requirements from a single competition? Generally, all recovery interventions are optimized during rounds of a competition, or throughout a competition, block to maximize subsequent performance.
What are the training or competition specific interventions to optimize performance? from tapering to warm-up to sport psychology Competition phase tends to offer unique nutrition periodization challenges, such as body comp optimization during tapering, optimizing recovery protocols, to acute competition specific ergogenic aids e.
Periodization of Energy Intake Energy intake EI is a primary nutritional characteristic as it a establishes the baseline from which intakes of the macronutrients including muscle substrates are derived, b influences the capacity of the diet to achieve micronutrient targets within nutrient-density constraints, and c allows the manipulation of physique via the interaction of training and energy balance.

CHO intake is then withheld in recovery or suboptimal intakes occur such that a second session is completed in the afternoon or early evening with reduced preexercise CHO availability.
Depending on the timing of both sessions, the total time considered in a state of low CHO availability could range from 3 to 8 hr. Hulston et al. This approach would predominantly target reduced liver glycogen associated with fasting in the overnight period though depending on the CHO intake consumed in the recovery period after the last training session, pretraining muscle glycogen may also be considered low.
Akerstrom et al. CHO intake is then withheld in recovery or suboptimal intakes occur such that a second session is completed on the subsequent morning with reduced preexercise CHO availability.
Depending on the timing of both sessions, the total time considered in a state of low CHO availability could range from 8 to 14 hr. The interactive effects of changes in substrate availability may sustain the postexercise upregulation of cell signaling e. The sleep-low train low model has been associated with improved exercise performance in trained triathletes.
Bartlett et al. Costa et al. In this model, an initial train high session may be completed to promote training intensity and duration followed by a second train low session that is performed 24—48 hr later with reduced CHO availability.
The second session may have arisen as a result of a combination of sleep-low, recover low, and a low daily absolute CHO intake. Impey et al. Figure 3 —Supplement individualization and piloting framework, including potential data collection variables to help inform protocol and efficacy.

Periodixation date, most methods have ;eriodization on skeletal muscle, gor Building a support system for young athletes Leafy greens for dips important to note that training effects also include adaptations in other tissues e. The purpose of this review is to define the concept of periodized nutrition also referred to as nutritional training and summarize the wide variety of methods available to athletes. The reader is referred to several other recent review articles that have discussed aspects of periodized nutrition in much more detail with primarily a focus on adaptations in the muscle. The purpose of this review is not to discuss the literature in great detail but to clearly define the concept and to give a complete overview of the methods available, with an emphasis on adaptations that are not in the muscle. Whilst there is good evidence for some methods, other proposed methods are mere theories that remain to be tested.Video
