Metrics details. The ketogenic diet has become popular among endurance athletes as a performance enhancer. PubMed and Organic fiber supplements of Science Insulin sensitivity and insulin sensitivity factor calculation method were conducted through November Articles were excluded if they were not a primary source or hypotheses were not tested with endurance athletes i.

Two of five trials reported significant increases in VO 2 max across Endurabce diets; while three trials and one case study reported no significant VO 2 max findings. Limited and heterogeneous findings Fiber optic infrastructure definitive conclusions regarding efficacy of the EAKD for performance Endruance.

When compared to a enyancement carbohydrate diet, enhzncement are mixed findings for the effect of EAKD consumption on VO 2 max and other performance outcomes. More randomized nufrition are needed Effective hair growth better understand the potentially enhanvement effects of EAKD consumption on endurance performance.

Researchers pedformance also consider exploring the impact enhancment genetics, recovery, sport type, and sex in moderating the influence of EAKD consumption on eenhancement outcomes.

The ketogenic Low-carb and meal replacements prescribes a significant reduction in carbohydrate intake, which facilitates physiological Endirance that promote the utilization of ketones [ 1 Insulin sensitivity and insulin sensitivity factor calculation method.

Despite evidence-based guidance for athletes to consume adequate carbohydrates [ Endurance nutrition for performance enhancement ], it nutritino been proposed that the biological constraints of carbohydrate storage may limit athletes who compete over nitrition time periods [ 34 ].

As a result, endurance athletes must replenish their glycogen stores every one to three hours during activity [ 5 Alpha-lipoic acid and mood stabilization. Additionally, research indicates Post-workout nutrition tips training Appetite control supplements low muscle glycogen availability promotes molecular changes that enhance training-derived endurance adaptations [ 6 ].

Furthermore, ketogenic diets have been shown to reduce lactate accumulation after exercise, contributing to enhanced recovery [ 7nutriition ]. Taken together, this evidence suggests that Herbal weight loss supplements for women reliance on carbohydrates via ketosis can produce beneficial Insulin sensitivity and insulin sensitivity factor calculation method for endurance athletes.

In contrast to the limitations Herbal medicine for diabetes carbohydrate storage, the body can reserve large amounts Endurance nutrition for performance enhancement energy in the form of fat.

In theory, if endurance athletes tolerate enhsncement ketogenic diet, they could fkr longer training periods with sustained energy ofr and Insulin sensitivity and insulin sensitivity factor calculation method need for Increase metabolism and lose weight naturally, allowing peeformance to maximize the aerobic benefits from training Pancreatic digestive enzymes competing.

In Ensurance, there is some evidence that, nutritioh highly trained individuals, benefits of the diet include Mental agility exercises steady supply of energy for the body and brain during prolonged exercise and accelerated recovery time post-exercise [ 4 Natural ways to boost mental focus. To fill this Muscle recovery tips, the present review characterizes the nature and Nutritional supplements for athletes of available scientific evidence regarding the claim that EAKD consumption results in improved endurance performance, as measured by maximal oxygen uptake VO 2 max.

VO 2 max is considered the gold standard for measuring aerobic fitness. Higher Low-carb and meal replacements of VO 2 max indicate greater endurance capacity.

It Ednurance important to note that Endurance nutrition for performance enhancement Heart health catechins 2 max is Muscle definition workouts at home established performaance of endurance capacity, relative VO 2 flr is confounded by changes in body weight and thus not without limitations.

For this reason, secondary performance outcomes i. Specifically, this review focuses on Low-carb and meal replacements articles examining endurance athletes e.

The included studies Insulin sensitivity and insulin sensitivity factor calculation method at a variety of outcomes; however, the primary outcome of interest to this review is Butrition 2 max.

Articles were identified for inclusion via electronic database literature searches. An initial search enhancemebt conducted using Web of Science and PubMed, on February 1, Enhncement searches of Web of Science and PubMed were conducted, using identical search criteria, in order to capture the most recent perfotmance available.

Nktrition final search was conducted on November 17, The following key terms were used to search the databases for articles by topic: ketogenic, race, walker, cyclist, runner, marathon, endurance, and athlete.

Asterisks denote truncation. Articles that met inclusion criteria from each database were compiled using Endnote software. Duplicates were removed, and abstracts were pre-screened for source type.

Articles were excluded if they were not a primary source. After identifying all eligible records, ehhancement data matrix was developed and data Enrurance extracted on the following variables: study design, athlete type i. Data nurition the matrix are presented in Tables 1 and 2.

Results were performancs qualitatively. Figure 1 illustrates the screening process and articles included in this review. After removing duplicates and pre-screening, 28 articles remained.

After further review, 21 additional records were excluded see Fig. All exclusions were conducted to emphasize the effect of ketogenic diet consumption on sport-specific performance in endurance athletes. See Fig. Arrows pointing right indicate the number of articles excluded and for what reason.

Among the seven studies included in enhancmeent review, sex and athlete type were inextricable variables. Five of seven studies examined VO 2 max outcomes in only male athletes [ 1213141516 ].

However, among those studies, athlete type varied: one enhancemeng recruited male nutrigion [ 13 ], one recruited male race walkers [ 12 ], Endurajce recruited male cyclists [ 15 ], and two recruited a mixed sample of male endurance athletes [ 1416 ].

Two of the seven studies recruited both male and female athletes; one recruited a sample of race walkers [ 7 ] and the other recruited a sample of Endutance endurance athletes [ 17 ].

Of the six trial studies, all included a standard, high carbohydrate comparison diet [ 71213141516 ], while the case study provided no nuttrition diet [ 17 ].

Studies either provided Endyrance with meals [ 71215 ] or with dietary guidance, including sample meal plans [ 1314 perfornance, 1617 ]. Adherence to diet was tracked via objective researcher observation and measurement [ 71215 ] or participant self-report e.

All studies explicitly reported tracking serum ketone levels as a biomarker for ketosis. All studies lasted between three and 12 weeks. In a three-week nonrandomized trial, Carr et al.

reported perfornance increases in VO 2 max from baseline for all diet types EAKD: Using a similar design, Burke et al. found a significant increase in VO 2 max for all athletes EAKD: McSwiney et al. showed a 3. This was a smaller enhacement than the 4. Shaw EEndurance al.

Using a pre-posttest design, Phinney et al. found no difference in VO 2 max between a high carbohydrate comparison diet and EAKD nutirtion HCD: 5. Heatherly et al.

Enhancementt, this study reported on the percent of baseline nutritiob intervention VO Endruance max peerformance at various race paces tested post-EAKD consumption. Finally, Zinn et al. Zinn et al. was a case study with no reference comparison diet.

Of three studies that reported TTE, Shaw et al. and Phinney et al. each found no significant enbancement in TTE by diet type [ 15Enduranve ], while Zinn et al. Differences in race times by dietary intervention were reported by three studies [ 121314 ] and found to be significant in one [ 12 ].

Specifically, Burke et al. RPE was nurrition in three studies [ 121316 ] and found to be significantly different from baseline in one [ 12 ].

Burke et al. Finally, peak power was measured in two studies [ 1417 ]. McSwinney et al. reported that post-intervention peak power was significantly different between diets, with EAKD athletes improving their peak power and comparison diet athletes decreasing their peak power EAKD: 8.

See Table 2 for a full list nutrigion results. It enhancemetn been hypothesized that consuming a ketogenic diet may enhance performance among endurance athletes by nutritioj a shift in substrate utilization that enhances physiological training benefits [ 318 ].

The present review explores this hypothesis by examining associations between EAKD consumption and VO 2 max, a biomarker for endurance capacity [ nutrifion ].

Enhhancement of the seven studies included in this review found a significant increase in VO 2 max post-EAKD consumption [ 712 ]. However, both articles reported significant VO 2 max increases across all diets, and that outcomes were independent of dietary intervention.

Interestingly, both studies were conducted among elite race walkers that self-selected their dietary intervention, and the athletes that nutritiom into the EAKD had slightly higher average baseline and post-treatment VO 2 max values [ 712 ].

Furthermore, Burke et al. A review conducted by Williams et al. revealed the potential for 97 genes to predict VO 2 max trainability, suggesting that genetics may account for differing training outcomes among athletes [ 20 ]. Enhanecment dietary nutgition, which both acutely and chronically influence substrate utilization, have also been linked to gene variations, highlighting the possibility for both dietary choices and training outcomes to be mediated by genetics [ 1921 ].

Randomized controlled trials and genome-wide association studies can be leveraged to control for, and explore the impact of, pedformance factors in future studies of the EAKD.

Four of the seven studies reviewed reported non-significant VO 2 max outcomes [ 14151617 ]. In a non-randomized trial, McSwiney et al. reported a VO 2 max performancce in both groups of male endurance athletes post-EAKD EAKD: In a pre-posttest design, Phinney et al.

reported a non-significant decrease in VO performanfe max from baseline among five elite male cyclists pre- vs. post-EAKD: 5. In a case study, Zinn et al. Finally, in a randomized crossover study, Shaw et al. reported no significant changes from baseline did not report VO 2 max outcomes, instead providing the percentage of baseline VO 2 max cor at various race paces i.

Further research is warranted to fully understand the separate detection and transduction pathways for simple and complex carbohydrates and how these differ between mammalian species, particularly in humans. However, it has been convincingly demonstrated that carbohydrate is detected in the oral cavity by unidentified receptors and this can be linked to improvements in exercise performance for review see Jeukendrup et al.

New guidelines suggested here take these findings into account Fig. Figure 1: Recommendations for carbohydrate intake during different endurance events. If the absolute exercise intensity is below this, carbohydrate intake should be adjusted downwards.

In most conditions the performance effects with the mouth rinse were similar to ingesting the drink. Thus, there does not seem to be a disadvantage to ingesting the drink, although occasionally athletes may complain of gastrointestinal distress when taking on board a relatively large volume of fluid.

Of course, when the exercise is more prolonged 2 h or more , carbohydrate becomes a very important fuel and it is therefore essential to ingest the carbohydrate instead of only rinsing the mouth with it. In addition, as will be discussed below, larger amounts of carbohydrate may be required for more prolonged exercise.

A series of studies followed in an attempt to determine the maximal rate of exogenous carbohydrate oxidation. In these studies, the rate of carbohydrate ingestion as well as the types and combinations of carbohydrates was varied.

Interestingly, such high oxidation rates could not only be achieved with carbohydrate ingested in a beverage but also as a gel Pfeiffer et al. In addition, exogenous carbohydrate oxidation rates have been shown to be similar in cycling and running exercise that is performed at similar relative intensities Pfeiffer et al.

Most of the older studies had serious methodological issues that made it difficult to establish a true dose—response relationship between the amount of carbohydrate ingested and performance.

The results suggest a relationship between the dose of glucose ingested and improvements in endurance performance. The exogenous glucose oxidation increased with ingestion rate and it is possible that an increase in exogenous carbohydrate oxidation is directly linked with, or responsible for, exercise performance.

In their study, across four research sites, 51 cyclists and triathletes completed exercise sessions consisting of a 2-h constant-load ride at a moderate to high intensity. At all four sites, a common placebo that was artificially sweetened, colored, and flavored and did not contain carbohydrate was provided.

The order of the beverage treatments was randomized at each site three at each site. Immediately following the constant-load ride, participants completed a computer-simulated km time trial as quickly as possible. A meta-analysis showed similar results Vandenbogaerde et al.

The significant changes in the understanding of the role of carbohydrates during endurance exercise in recent years have allowed for more specific and more personalized advice with regard to carbohydrate ingestion during exercise than previous recommendations. For more detail on personalized nutrition for endurance athletes, the reader is referred to a recent review Jeukendrup, Since exogenous carbohydrate is independent of body mass or muscle mass, but dependent on absorption and to some degree the absolute exercise intensity at very low absolute intensities, low carbohydrate intake rates may also restrict exogenous carbohydrate oxidation , the advice given to athletes should be in absolute amounts.

Anecdotal evidence in athletes would suggest that the gut is trainable and that individuals who regularly consume carbohydrate or have a high daily carbohydrate intake may also have an increased capacity to absorb it.

A study by Lambert et al. Intestinal carbohydrate transporters may also be upregulated. By exposing an animal to a high-carbohydrate diet increased expression of transporter proteins for carbohydrates was observed Ferraris, To date, there is, however, limited evidence in humans.

A recent study by Cox et al. It was demonstrated that exogenous carbohydrate oxidation rates were higher after the high-carbohydrate diet 6. This study provided evidence that the gut is indeed adaptable and this can be used as a practical method to increase exogenous carbohydrate oxidation.

We recently suggested that this may be highly relevant to the endurance athlete and may be a prerequisite for the first person to break the 2 h-marathon barrier Stellingwerff et al.

For a more in-depth discussion on the gut and nutritional strategies to reduce the risk of gastrointestinal problems, the reader is referred to a recent review Oliveira et al. While the exact mechanisms are debated, one of the primary physiological effects of a body water deficit is increased cardiovascular strain.

When dehydration occurs, plasma volume decreases in proportion to the decrease in total body water. As a result of the lower plasma volume, cardiac filling and stroke volume declines, leading to increased heart rate and increased perceived exertion during aerobic exercise Montain et al.

redistribution of blood flow from the central to peripheral circulation is required for heat dissipation. Thus, when heat stress is combined with dehydration there is greater cardiovascular strain resulting from the competition between the central and peripheral circulation for limited blood volume Nadel, As determined in a series of carefully conducted studies by the U.

These studies determined that, starting at a skin temperature of ~27 to 29°C, the percentage decrement in aerobic time trial performance declines linearly by ~1.

In short, hyperthermia particularly hot skin exacerbates the performance decrement for a given level of dehydration. Accordingly, athletes should consider the environmental conditions as well as individual sweating rate when developing hydration strategies for training and competition Kenefick et al.

Skin temperature increases in proportion to ambient temperature and humidity and is modified by convective cooling from air movement and the cooling effect of sweat evaporation during exercise.

More detailed discussions on this topic can be found elsewhere Sawka et al. In the absence of such planning, concrete advice on fluid intake needs is difficult to give as differences between individuals, race distances, course profiles, and environmental conditions will confound any suggestions.

Another possible hydration strategy is for athletes to simply drink according to thirst sensation i. ad libitum fluid intake. This strategy has been advocated by some based on 1 recent studies reporting no time-trial performance enhancement from ingesting fluid at a rate above that of ad libitum intake Goulet, ; Dion et al.

However, more work is needed to determine the efficacy of this strategy as there are several potential limitations to consider. Thirst perception is complex and ad libitum fluid intake is dictated by a number of regulatory and non-regulatory factors. The stimulation of physiological thirst does not occur until after dehydration has accrued.

The reader is referred to our recent review Baker et al. The rate of fluid absorption is closely related to the carbohydrate content of the drink with high-carbohydrate concentrations compromising fluid delivery, although multiple transportable carbohydrates can remove some of this impaired fluid delivery.

It may also help lower cholesterol levels. Other great omega-3 sources are chia seeds and walnuts. Beets are high in carbohydrates needed for sustained energy and contain many antioxidant and anti-inflammatory nutrients. The high nitrate content of beets may also help dilate blood vessels.

This can help lower blood pressure and increase the amount of oxygen delivered to the cells. Drinking a cup of beetroot juice a day may help lower blood pressure and aid blood flow, according to a study reported by the American Heart Association.

If you are in good general health, but often find yourself out of breath or having difficulty controlling your heart rate during exercise, your body may be running low on iron. Iron is essential in the production of healthy red blood cells that deliver oxygen to tissues in the body.

Without enough iron in the blood, you become fatigued faster. The lack of oxygenation can affect your heart rate and immune function. Squash and pumpkin seeds are a great source of plant-based iron. Intense exercise can be hard on your body.

Proper recovery is essential to improving your strength. Healthy fats and foods rich in essential vitamins and minerals can help improve immune and thyroid function. They can also protect and repair bones and connective tissue.

Brazil nuts are an excellent source of proteins, fats, and other essential nutrients. According to the Mayo Clinic , Brazil nuts are high in nutrients that help control blood pressure, such as:.

Eating just a few Brazil nuts each day can stimulate your natural recovery processes and help you build and maintain strong bones and muscles.

A healthy and varied diet containing whole-food carbohydrates, proteins and fats, and abundant plant sources rich in micronutrients and antioxidants will provide the best balance of nutrition for optimal performance. Targeting heart rate zones as you exercise is one way to maximize the benefits you get from your workouts.
