Calorie intake for endurance activities -
Research shows that this intake should be higher than what many athletes will actually consume, with general recommendations being 1. This intake is similar to athletes that train anaerobically such as for strength and power.
Also protein synthesis has been shown to increase following endurance training, placing further need for adequate daily protein intake. The benefits from this are clear with many athletes reporting improved recovery and muscle maintenance. This should be based on the overall caloric intake of the diet, how intensely and frequent they train and whether they want to gain or lose weight.
We previously established that carbohydrates are important in the hours prior to exercise, and studies show that protein should be included here too. Protein intake prior to exercise can help maintain energy levels, increase levels of satiation and provide ample levels of amino acids.
To reap the most benefit from this research supports that intake of protein should be taken alongside carbohydrates and within hours prior to exercise. The magnitude of protein usage during endurance exercise is an important consideration for athletes.
Research has shown that the body will excrete certain amino acids from muscle and oxidize and metabolize them during training. Protein will aid in the recovery process for athletes, but not as much as carbohydrates for endurance exercise.
Research has suggested that by consuming carbohydrates with protein post exercise, athletes will see greater glycogen replenishment than with carbohydrates or protein alone. A further benefit is that the increased levels of amino acids will aid recovery and muscle repair.
Protein should be consumed with fast acting carbohydrates, minutes post exercise, and these too should be fast and easily digested e. whey protein powder. Consumption of protein in subsequent meals should be sufficient to continue the recovery process and to meet daily requirements.
Therefore when calculating fat requirements, both protein and carbs take precedence over fat. There are also no essential requirements for the use of fat prior, during or immediately post endurance exercise - simply meet daily targets.

Due to the demands of endurance training, its depleting nature and the stress it puts on the body, endurance athletes can see benefits from including high levels of certain vitamins and minerals.
Thiamin, riboflavin and niacin are the key B vitamins for endurance athletes. B vitamins are potent for energy production so increased daily levels are important.
The intake of high B vitamin foods is recommended with possible supplementation. These are potent antioxidants that reduce oxidative damage. They can also work in synergy with one another, making their benefits greater when combined.
Vitamin C should be consumed at mg per day and vitamin E at mg per day. This can be achieved through a diet including ample amounts of fruit and veg, but may also be supplemented.
Iron is a common deficiency and endurance athletes are at greater risk of this, as they lose more via urine and sweat. Iron aids in transporting and utilizing oxygen, and is important for maximum performance.
A diet rich in iron foods should be sufficient. It is also used to aid muscle contraction and relaxation, movements essential for endurance athletes to maintain at peak performance for a time.
Calcium also activates several enzymes that affect the synthesis and breakdown of muscle and liver glycogen, a main energy source for endurance athletes.
Adequate levels of calcium can be achieved through the diet, but supplementation should be used if the athlete is not reaching RDA levels. Both sodium and potassium are important electrolytes to endurance athletes. Electrolytes aid the interchange and flow of nutrients into and out of cells, and are responsible for nerve impulses and muscle contraction.
They are commonly lost in sweat, making a greater demand for them to ensure optimal performance in athletes. Most people achieve sufficient sodium in the diet, but a small pinch of salt added to meals may also prove beneficial.
Potassium can be improved from an increased amount of fruit, vegetables and dairy products. Theses electrolytes are commonly added to sports beverages, which can be used during times of exercise. We already know the importance of water from our previous article, and that it is the most important nutrient and is critical to life.
For endurance athletes, the functions of water in the body plays further important roles such as regulating body temperature heat regulation via maintenance of blood plasma volume and reduces the amount of oxygenated blood pumped to working muscles. We also know that proper hydration leads to optimal endurance and performance.
Athletes are at greater risk of dehydration from prolonged exercise and must therefore continually monitor their fluid intake through the day to control this.
For every pound in weight lost after the event, it should be replaced by ml of water, with no more than ml per hour. If weight gain occurs, athletes should hydrate less and monitor their hydration levels.
Fluid intake and hydration levels are highly individual, so the responsibility for optimal hydration falls in the hands of the athlete, and only they know how to ensure their own optimal hydration day to day.
Meal frequency is a personal preference and this still remains true for nutrition for endurance athletes. Due to potential high levels of food intake and in particular carbohydrates, smaller and regular meals appear to work well for many.
This helps break up the daily calories to reduce any bloating or sluggishness from larger meals. Although these can all be obtained from the diet, supplementation can be effective to ensure daily allowances are being met.
Performance supplementation has also extended into the endurance world, and there are a number of options for athletes to now use. Providing they are of high quality with effective and safe ingredients, they can be used to boost performance.
Particular supplements that have been created around the exercise window, to aid the delivery of nutrients and natural performance enhancers, can provide additional benefits that are worth considering. After exercise begins, however, sympathetic nervous system hormones inhibit GI impact on insulin release.
Unless your caloric intake exceeds the maximum that the liver can return to the body in the form of glycogen about calories per hour , glycemic index is not a major factor in choosing energy sources.
During exercise, it's a nutritional error to value GI above saccharide profile. With some allowances provided for very large athletes the human body can only return from the liver to muscle tissue about 4. When an athlete consumes more than calories per hour from carbohydrates during an event, the excess remains undigested in the stomach, or passes unused into the bowel, where, in the unmincing words of Dr.
Bill Misner, "they accumulate in gastric or intestinal channels in degree temperatures and putrefy in time. Yes, you may be burning up to calories per hour, but your body cannot replace that amount during exercise.
Trying to replenish calories at the same rate as depletion only causes problems. Instead of having more energy available, you'll have a bloated stomach, and perhaps even nausea and vomiting.
You've seen it happen, but it's not a necessary aspect of intense competition; more likely it's the result of improper caloric intake. If we can't replace all the calories we expend, then how do we keep going hour after hour?
The answer is the practically limitless supply of calories in body fat. The typical athlete can count on a reserve of up to , calories in the form of stored fatty acids—that's enough, if you could process it all, to fuel a run from Portland, Oregon to Los Angeles, California—a distance of almost miles!
In other words, your body has a vast reservoir of calories available from body fat stores, and it will use those liberally to satisfy energy requirements during lengthy workouts and races. However, for this process to continue without compromise or interruption, you must not consume excess calories.
If you try to match energy losses with caloric replacement from your fuel, you will not only cause a variety of stomach-related ailments, you will also inhibit the efficient utilization of fats for fuel.
As mentioned in "The 10 Biggest Mistakes" article, caloric donation from consumed fuels must cooperate with your internal fat-to-fuel conversion system.
Do not attempt to completely replace caloric expenditure. Your best strategy is to replenish calories in amounts that support efficient energy production and do not interfere with the use of fatty acids for fuel.
For what that means in real life training and racing, see the chart at the end of this article. When exercise goes beyond 90 minutes, you need to incorporate some protein into the fuel mix.
This process, called gluconeogenesis, is unavoidable, and if you don't supply the needed protein in your fuel, your body will literally scavenge it from your own muscle tissue.
This is called catabolism muscle breakdown , known informally, but quite accurately, as "protein cannibalization. Protein cannibalization also compromises your immune system, leading to increased risk for colds, flu, and other diseases. For exercise and competition that extends about two hours or more, your primary fuel should incorporate protein in a ratio of about by weight carbs to protein.
Both Sustained Energy and Perpetuem meet this requirement; they are your best choices for fueling any endurance activity. As noted above, it's good to have a little protein along with your complex carbs to avoid the negative effects of muscle catabolism, but you must have the right kind of protein.
The preferred protein for use during prolonged exercise is soy, primarily because its metabolization does not readily produce ammonia. Whey protein, with its high glutamine content, makes an excellent post-workout protein, but is not a good choice before or during exercise.
Soy protein has a couple other great features, too. First, it is an easily digestible protein. Second, it has an excellent amino acid profile, with a substantial proportion of branched chain amino acids, or BCAAs, which your body readily converts for energy.
During exercise, nitrogen is removed from BCAAs and used in the production of another amino acid, alanine, high amounts of which also occur naturally in soy protein. The liver converts alanine into glucose, which the bloodstream transports to the muscles for energy.
BCAAs and glutamic acid, another amino acid found in significant quantity in soy protein, also aid in the replenishing of glutamine within the body without the risk of ammonia production caused by orally ingested glutamine.
Also, soy produces more uric acid than whey protein. This might not sound good, but uric acid is actually an antioxidant that helps neutralize the excessive free radicals produced during exercise. High uric acid levels, from soy's naturally occurring isoflavones, are another strong reason for preferring soy protein during endurance exercise.
If you've read this far, you might be thinking, "Enough with the biochemistry lessons! According to a study , vitamin C also helps athletes recover during the competitive season 2.
Citrus fruits and potatoes are high in vitamin C. So are peppers, broccoli, strawberries, and kiwi. Vitamin D is important for bone health. Weak bones mean more fractures and breaks. A study also ties adequate vitamin D levels with improved athletic performance 3.
Taking a cod liver oil supplement is one way to get more of this nutrient. Orange juice and dairy are also high in vitamin D.
We lose water throughout the day. It escapes our body through normal respiration, sweating, and urinary output. When we exercise, we lose more. Staying hydrated is more than about satisfying thirst.
The top reasons for proper hydration, which are especially important for clients taking on endurance events, include:. Endurance athletes need to watch their hydration throughout the day, especially during workouts.
Water intake guidelines are provided by the National Academies of Sciences, Engineering, and Medicine 4. Current guidelines are 2. This includes water consumed both from beverages and food. When your client is taking part in endurance activity, they need to up their intake.
Here are some recommendations to follow:. After endurance exercise: 24 ounces for every pound of body weight lost.
In addition to water loss through sweating, we also lose electrolytes. When we sweat, we lose sodium, chloride potassium, magnesium, and calcium. These electrolytes serve important roles in supporting bodily systems.
There are many electrolyte drinks on the market. These can help replace lost nutrients. Many exist in the form of a sports drink. The problem is that these drinks can also be high in sugar and calories. One of the best ways to replenish electrolytes after a long endurance training session is by eating whole foods.
Here are a few options to consider:. Potassium - banana, sweet potato, dried fruits, avocado, kale, peas, beans. Magnesium - whole grains, leafy vegetables, nuts, lentils, peanut butter. Achieving peak performance requires having nutrients available when you need them.
This can be accomplished by developing a nutrient intake plan. And this plan should provide nutrient timing guidelines. Timing the intake of carbohydrate, protein, fat, and water is essential to endurance success.
It involves laying out what to consume before, during, and after endurance training and endurance events. Consume 20 ounces of water 2 hours before the start of endurance training. Carbohydrate loading should only occur leading up to an endurance event.
Consume 1. Consume 15 to 25 grams of protein within the first 30 minutes post-exercise. Nutrition for endurance involves a lot. But when endurance athletes pay attention to the recommendations and figure out what methods work best for them, the outcome is improved athletic performance.
This can translate to higher awards come race day. Whether you are an elite athlete, a weekend warrior, or a personal trainer designing programs for athletes, it is important to fuel the body properly.
