Even for efficient endurance Mind-body nutrition approaches ultra-endurance athletes, carbohydrates are still Fat intake for sports performance, but stored fats forr them reach the dor line.

Research has shown that Noninvasive glucose monitor adaptations do occur as a result of high fat fueling, although claims that high fat, carbohydrate-restricted diets improve performance in competitive athletes have not been proven.

This has significant implications for athletes in muscular endurance sports that require a burst of power, such as rowing, swimming, gymnastics, figure skating, judo, boxing, baseball, basketball, or soccer, to have energy generated aerobically. It is important to recognize that there are many sources of fat in foods.

It is present, but not separately visible, in:. Other more obvious sources of fat are in products like margarine, butter, mayonnaise, salad dressing, oils, and meats with marbling or visible fat. Along with decreasing overall calories, increasing mono-unsaturated and n-3 polyunsaturated fats while decreasing consumption of saturated fat and sugar-sweetened beverages soda are the first steps toward losing excess body fat and improving metabolic function.

Doing so may be a benefit to athletes by reducing inflammation and helping to maintain proper vascular function, which indirectly may support athletic performance.

However, the available data do not allow for any estimates beyond this. Given the popularity of city marathons and high-intensity fitness classes, there is a need for further research. Studies have been conducted for about 35 years on whether the availability or oxidation rate of fatty acids in the active muscles can be increased by varying the fat content in food or using dietary supplements. The aim is to protect the glycogen reserves 63 , which hypothetically leads to an improvement in endurance performance. Fat loading is a pre-competition strategy that is practiced either three to four hours before the start acute or five and more days before the competition chronic. Chronic fat loading can be further distinguished into ketogenic and non-ketogenic low-carb, high-fat LCHF diets. The interest in fat loading resurged during the past five years 4 , 33 , 52 , 71 , although not many new studies have been conducted. Since fat loading is getting increasing exposure on internet platforms and blogs for the search terms ketogenic diet performance 7,, results on google. com on August 31, , the different strategies are briefly introduced and critically examined below. Included in the position statement presented here are all identified contributions in which the subjects were athletes with moderate to very high performance levels. For space reasons the focus of this paper is on endurance sports. Acute Fat Loading. Studies involving competitive athletes show that a high-fat loading meal does not positively influence the time to exhaustion, but instead may even shorten it:. The performance was not improved 30 , Concerns about gut comfort after ingesting a high-fat loading meal were not addressed in any of the mentioned studies. However, a correlation between high fat intake and gastrointestinal distress can be observed particularly in endurance sports Ketogenic LCHF Diet Short: Ketogenic Diet. The studies which were mostly performed in the realm of endurance sports reveal no positive effects on performance capacity, but may even show negative effects:. The maximum work load on the bicycle ergometer was lower They assume that possible performance reductions were offset by the observed weight loss of 2. The increase in relative power in a simulated final sprint can be attributed to an improved power-to-mass ratio resulting from a weight reduction by 5 kg in three months The authors propose that the low-carbohydrate diet prevented a positive training effect, which could partially be attributed to a reduced exercise economy 8. Additionally, there seems to be a plausible link between a ketogenic diet, shifts in the bacterial colonization in the gut, and impairments in exercise capacity Concerning the long-term health impact of this dietary intervention, it must be noted that a 3. Five weeks after switching to a diet rich in carbohydrate, he finished second and fourth in two Ironman events separated by only three weeks. Reported beneficial effects during short duration vigorous, and sprint bouts of exercises are most likely confounded by greater weight loss in the ketogenic diet group. A striking observation, when considering the extensive carbohydrate restriction in a ketogenic diet, is that it is at odds with the widely accepted nutritional guidelines for athletes 66 and the food-related recommendations by the DGE for a balanced diet 16 , Micronutrient-dense foods, such as fruit, potatoes or cereal products, can only be consumed in very limited amounts in a ketogenic diet. It is therefore possible that long-term use can lead to negative effects on health, nutrient supply and performance. Based on endurance-oriented studies, it can be inferred that the non-ketogenic LCHF diet does not have a significant influence on performance or may even have a negative influence:. What has been shown so far about fat-loading strategies leads to the conclusion that a fatty acid oxidation rate that has been moderately increased by a higher fat intake 58 has no benefit with respect to endurance performance. It can be assumed that the disadvantage of reduced muscular glycogen reserves outweighs the benefit of a glycogen-sparing effect during physical exercise. However, the study results suggest that the combination of an LCHF diet with carbohydrate loading does not have a positive effect on endurance performance:. In summary, it can be assumed that during intermediate and final sprints, glycolysis is limited owing to a downregulation of the pyruvate dehydrogenase activity caused by an LCHF diet This means that the upregulation of fatty acid oxidation is ultimately more likely to result in a limitation of glycogen use than to have a glycogen sparing effect 5. In addition, it is possible that during an exercise bout after fat loading, the higher concentrations of free fatty acids and ammonium ions in blood plasma promote general fatigue This is why high-fat dietary practices are discouraged. The influence of various dietary supplements on the availability or oxidation rate of fatty acids has been studied repeatedly. The hypothesis underlying these studies is that an increase in energy supply from fatty acids could spare glycogen and thus enhance endurance performance. Does it make sense to use food supplements is discussed below. Caffeine was on the list of banned drugs until Heretofore, it was assumed that the alkaloid stimulates the release of adrenaline, thereby increasing the mobilization of fatty acids from adipocytes and myocytes, which can be used as energy sources Graham et al. Nor could Greer et al. This is why the metabolic theory was discarded. As a matter of fact, caffeine has a positive psychotropic effect which is discussed in detail elsewhere During exercise of moderate intensity, carnitine functions as a carrier of long-chain fatty acids through the inner mitochondrial membrane. In the case of high work loads, carnitine buffers excess acetyl residues, thereby preserving the pool of free coenzyme A, an essential factor in oxidation reactions pyruvate dehydrogenase, citrate cycle enzymes 58 , 60 , This is because orally ingested carnitine does not increase the carnitine concentration in the myocytes 60 , According to the EFSA, carnitine does not favorably influence endurance capacity or recovery In the scope of testing carnitine tartrate for use in particular foods, the EFSA has rated an intended daily supply corresponding to 2 g of carnitine as well tolerated, and assured that gastrointestinal distress was only reported for consumptions of g of carnitine or more per day in tolerance studies Fish oil, which contains high amounts of EPA and DHA, was first recommended specifically for athletic purposes by Simopoulos In vitro, EPA results in an induction of the gene expression of acetyl-CoA carboxylase which regulates the fatty acid oxidation in the mitochondria However, human studies have not verified any influence of long-chain n-3 fatty acids on the proportionate energy supply from fat and carbohydrate, either at rest 53 or during exercise 2. This explains why fish oil has no effect on endurance performance, as Da Boit et al. For adults, the EFSA does not note any health concerns for a combined supplemention of EPA and DHA with amounts of up to 5 g per day or, if only EPA is supplemented, of up to 1. Medium-Chain Triglycerides MCT. Medium-chain triglycerides MCT contain fatty acids with a medium chain length C atoms. The maximum oxidation rate of 0. two to three hours 39 , 40 , Most of the few studies that have examined the influence of a combined intake of MCT and carbohydrate before and during endurance exercise show no indication of a glycogen sparing or performance enhancing effect 1 , 26 , 38 , 42 , Only van Zyl et al.

Heretofore, it was assumed that the alkaloid stimulates the release of adrenaline, thereby increasing the mobilization of fatty acids from adipocytes and myocytes, which can be used as energy sources Of course, dietary protein is needed for muscle repair and growth , but it is also needed to make enzymes — proteins that assist with thousands of chemical reactions that take place in the body — including the production of energy from food. Eating after exercise Rapid replacement of glycogen is important following exercise. Carbs should be eaten closer to physical activity because of the fast absorption — they can be used immediately. Dietary fat can be divided into four major categories:.
Why is protein, carbohydrate and fat important for athletic performance? - Food & Health	Anytime we are performing an activity in which we need a lot of energy and fast, such as resistance training and carrying bags of mulch, carbohydrates are the predominant energy source during those activities. Even at rest for example: lying in bed, sitting on the coach , our bodies still use carbohydrates, but fat is usually the major energy source during those conditions. Additionally, carbohydrates help us recover from physical activity, and prevent and reduce the breakdown of proteins in the body. The best sources of carbohydrates are typically those from foods that provide other nutrients such as dietary fiber and phytochemicals. These include whole grains such as oatmeal and wheat, and fruits and vegetables. Fats are also sometimes seen as negative, but this cannot be further from the truth. Fats serve numerous functions in the body including protecting our organs, helping absorb and manufacture some important nutrients, manufacturing some hormones, and also providing a source of energy. These functions are very important for general health, and for physical activity. Although, carbohydrates tend to predominate during physical activity, we still use some fat as fuel. During lower intensity physical activities and physical activities performed for a long duration, fuel from fats can be the predominate energy source. Some of the best sources of fats include olive oil, walnuts, fish, peanuts, and almonds. If you currently do not consume fat from these sources, make a goal to begin adding this kind of variety to your fat intake. Although protein, tends to get all of the glory when we think of physical activity, both carbohydrates and fats are also important. They both provide energy along with a host of other functions.

Low Carb Diets For Endurance Athletes

Fat intake for sports performance -

Water is a suitable drink, but sports drinks may be required, especially in endurance events or warm climates. Sports drinks contain some sodium, which helps absorption.

While insufficient hydration is a problem for many athletes, excess hydration may also be potentially dangerous. In rare cases, athletes might consume excessive amounts of fluids that dilute the blood too much, causing a low blood concentration of sodium. This condition is called hyponatraemia, which can potentially lead to seizures, collapse, coma or even death if not treated appropriately.

Consuming fluids at a level of to ml per hour of exercise might be a suitable starting point to avoid dehydration and hyponatraemia, although intake should ideally be customised to individual athletes, considering variable factors such as climate, sweat rates and tolerance.

Summary Read the full fact sheet. On this page. Nutrition and exercise The link between good health and good nutrition is well established. Daily training diet requirements The basic training diet should be sufficient to: provide enough energy and nutrients to meet the demands of training and exercise enhance adaptation and recovery between training sessions include a wide variety of foods like wholegrain breads and cereals , vegetables particularly leafy green varieties , fruit , lean meat and low-fat dairy products to enhance long term nutrition habits and behaviours enable the athlete to achieve optimal body weight and body fat levels for performance provide adequate fluids to ensure maximum hydration before, during and after exercise promote the short and long-term health of athletes.

Carbohydrates are essential for fuel and recovery Current recommendations for carbohydrate requirements vary depending on the duration, frequency and intensity of exercise.

Eating during exercise During exercise lasting more than 60 minutes, an intake of carbohydrate is required to top up blood glucose levels and delay fatigue.

Eating after exercise Rapid replacement of glycogen is important following exercise. Protein and sporting performance Protein is an important part of a training diet and plays a key role in post-exercise recovery and repair.

For example: General public and active people — the daily recommended amount of protein is 0. Sports people involved in non-endurance events — people who exercise daily for 45 to 60 minutes should consume between 1. Sports people involved in endurance events and strength events — people who exercise for longer periods more than one hour or who are involved in strength exercise, such as weight lifting, should consume between 1.

Athletes trying to lose weight on a reduced energy diet — increased protein intakes up to 2. While more research is required, other concerns associated with very high-protein diets include: increased cost potential negative impacts on bones and kidney function increased body weight if protein choices are also high in fat increased cancer risk particularly with high red or processed meat intakes displacement of other nutritious foods in the diet, such as bread, cereal, fruit and vegetables.

Using nutritional supplements to improve sporting performance A well-planned diet will meet your vitamin and mineral needs. Nutritional supplements can be found in pill, tablet, capsule, powder or liquid form, and cover a broad range of products including: vitamins minerals herbs meal supplements sports nutrition products natural food supplements.

Carbohydrates seem to be getting negative publicity in the press lately, so are they really important for physically active individuals? You bet. Not only from an athletic perspective, but carbohydrates are also important for general health.

Carbohydrates provide energy for the body including our muscles, brain, nerves and other body tissues. Anytime we are performing an activity in which we need a lot of energy and fast, such as resistance training and carrying bags of mulch, carbohydrates are the predominant energy source during those activities.

Even at rest for example: lying in bed, sitting on the coach , our bodies still use carbohydrates, but fat is usually the major energy source during those conditions. Additionally, carbohydrates help us recover from physical activity, and prevent and reduce the breakdown of proteins in the body.

Fat is the primary fuel for light to moderate-intensity exercise. It is a valuable metabolic fuel for muscles during endurance exercise and performs many important functions in the body, although it does not provide quick bursts of energy needed for speed. The more efficient an athlete becomes in their respective sport, the easier it is for them to operate at a lower intensity while maintaining the same level of work or maintaining the same speed metabolic efficiency. At this lower intensity, stored fat in the muscle can be used as a fuel source.

Nor could Greer et al. This is why the metabolic theory was discarded. As a matter of fact, caffeine has a positive psychotropic effect which is discussed in detail elsewhere During exercise of moderate intensity, carnitine functions as a carrier of long-chain fatty acids through the inner mitochondrial membrane.

This explains why fish oil has no effect on endurance performance, as Da Boit et al. For adults, the EFSA does not note any health concerns for a combined supplemention of EPA and DHA with amounts of up to 5 g per day or, if only EPA is supplemented, of up to 1. Medium-Chain Triglycerides MCT.

The maximum oxidation rate of 0. two to three hours 39 , 40 , Most of the few studies that have examined the influence of a combined intake of MCT and carbohydrate before and during endurance exercise show no indication of a glycogen sparing or performance enhancing effect 1 , 26 , 38 , 42 , Only van Zyl et al.

However, Goedecke et al. The authors speculated that the gastrointestinal symptoms especially intestinal cramps reported by some participants contributed to the impaired performance Ivy et al. Décombaz et al. Jeukendrup et al.

This amount is too low to influence performance, however. Coconut Oil. MCT in the form of coconut oil are currently experiencing a revival as part of the ketogenic diet for weight reduction The use of MCT to support weight loss is not to be recommended 14 , It can thus be assumed that coconut oil is not an effective means of reducing weight, for example as part of competition preparation.

In contrast to carbohydrate and protein, for which recommended intakes were internationally derived in g per kg of body weight and day for various types of sports, the reference value for fat intake is specified in terms of a percentage of energy supply.

They are insoluble in water and dissolve only in fat solvents. They are made up of building blocks called fatty acids, which are classified as saturated, monounsaturated or polyunsaturated depending on their chemical structure.

Unfortunately, the Irish population is consuming foods high in saturated fats such as fried foods as well as cakes, biscuits and pastries and this is contributing to the widespread dilemma of heart disease, diabetes and obesity.

Saturated fats are found in animal sources such as meat, egg yolk, yogurt, cheese and butter. They are also found in some vegetable oils including coconut and palm kernel oil.

This type of fat is normally solid at room temperature and is the biggest cause of high LDL levels bad cholesterol leading to problems such as heart disease and stroke. Trans fat is another type of fat that is found naturally in small amounts in meat and dairy products but much larger amounts are being produced in the production of partially hydrogenated vegetable oils.

Trans fats have been shown to have a bigger adversarial effect on blood cholesterol levels than saturated fats. It is therefore important to always read the back of pack labels and determine the proportion of trans fats in products before purchase.

Unsaturated fats on the other hand are normally liquid at room temperature. Monounsaturated and polyunsaturated fats help to reduce cholesterol levels and are found in vegetable oils such as olive, rapeseed and sunflower oil.

Omega 6 fatty acids are very common in the modern diet and can be found in most vegetable and nut oils as well as meat and dairy. In , the EFSA published its recommendations for essential fatty acids intake;.

On the flip side, fat intake can also be correlated with weight gain. High consumption of dietary fat is associated with increased levels of body fat and obesity. Fats are the densest source of energy, supplying about 9 kcal per gram.

This is more than double the number of calories provided by protein and carbohydrates per gram. Therefore, the key to successful weight loss is low dietary fat consumption whilst maintaining adequate protein and carbohydrate intake. As a general rule of thumb, we should try and cut down on the amount of saturated fats that we consume and opt for healthier foods containing unsaturated fatty acids like avocados, nuts and fish.

These foods comprise a typical Mediterranean diet, which is vastly linked with a lower rate of heart disease. Also try to incorporate vegetable oils such as olive, sunflower and rapeseed oils over those rich in saturated fats butter, palm, coconut oil into your diet.

As already stated fat provides the highest amount of energy out of all the nutrients — 1g of fat equals nine calories. This calorie density makes fat one of our largest energy reserves. When oxidative metabolism is possible we use fat for energy quite well.

Even at rest for example: lying in bed, sitting on the coach , our bodies still use carbohydrates, but fat is usually the major energy source during those conditions. Additionally, carbohydrates help us recover from physical activity, and prevent and reduce the breakdown of proteins in the body.

The best sources of carbohydrates are typically those from foods that provide other nutrients such as dietary fiber and phytochemicals. These include whole grains such as oatmeal and wheat, and fruits and vegetables.

These functions are very important for general health, and for physical activity. Although, carbohydrates tend to predominate during physical activity, we still use some fat as fuel. During lower intensity physical activities and physical activities performed for a long duration, fuel from fats can be the predominate energy source.

Some of the best sources of fats include olive oil, walnuts, fish, peanuts, and almonds. If you currently do not consume fat from these sources, make a goal to begin adding this kind of variety to your fat intake.

Although protein, tends to get all of the glory when we think of physical activity, both carbohydrates and fats are also important. They both provide energy along with a host of other functions.
