Some research has found that inclusion of small amounts of protein during prolonged activity can help enhance performance by sparing muscle glycogen as well as aiding fluid uptake. Protein also can help mute hunger that arises during longer efforts. Athletes on restrictive energy intakes should aim for the high end of this recommendation.

Race Morning: Include grams of protein in the hour leading up to race start to help stabilize blood sugars. Common pre-race protein sources include peanut butter, non-fat milk or yogurt, eggs, and energy bars. During Race: If out on a training or race course longer than 4 hours, aim for up to 5 grams of protein hourly.

Common sources include sports drinks, energy bars, as well as whole food alternatives like turkey jerky and peanut butter sandwiches. Post-Race: A range of grams of protein taken immediately post-race is sufficient to support muscle repair and immune function post-event.

Common sources include milk, meal replacement shakes, and specialized recovery sports drinks. Replacement of electrolytes becomes instrumental in endurance bouts lasting longer than 1 hour, especially when training and racing in hot and humid conditions.

The principle electrolytes include sodium generally bound to chloridepotassium, magnesium, and calcium. These electrolytes are involved in metabolic activities and are essential to the normal function of all cells, including muscle function.

Pre-Race: Athletes vulnerable to muscle cramping and fatigue as well as those competing in heat may benefit from increasing salt intake in the few days leading up to race day. Many of the carbo-loading options, such as pretzels, sports drinks, breads, and cereals, accommodate this. Similarly, on race morning, choosing saltier carbohydrate sources, such as a salt bagel, and sipping on a sports drink rather than plain water may help.

Salt loading is not recommended for athletes on blood pressure medications. During Race: Aim for mg of sodium per standard bike bottle of water consumed ounces as well as smaller amounts of potassium, magnesium, and calcium. Note that too much sodium can lead to bloating and GI discomfort so be sure to account for all your sources, including sports drinks mg per 8 ozenergy gels mg per packet and chews mg per 3 piecessalt packets ~ mg per packetand electrolyte capsules ~ mg per capsule.

Post-Race: Sipping on a sports drink, rather than plain water, post-race will facilitate optimal rehydration of muscles, including replacement of lost electrolytes. Because water serves as the medium for all metabolic activity, helps to lubricate our muscles and joints, and also keeps our core body temperature in check, failure to take in enough fluids during a long run can have a dramatic negative impact on both health and performance.

Therefore, determination of sweat rate and consequent fluid demands is extremely important for athletes. Daily: Drink half your body weight in pounds in fluid ounces or so urine runs pale yellow during the day. For example, a lb man requires approximately 75 ounces of fluid daily.

Unfortunately, this level of dehydration can have significant negative consequences on performance so be sure to sip on ounces of fluid in the hours leading up to race start or so that urine runs pale yellow.

During-Race: Aim for ½-1 liter or approximately 1 standard bike bottle ~ ounces per hour or so that urine runs pale yellow. It is important to note that over-hydration, also known as hyponatremia, can be just as dangerous as dehydration and is generally caused by consuming fluids, especially water, beyond that of what the body can absorb.

Cardinal symptoms of over- hydration include clear urine, pressure headaches, nausea, vomiting, and confusion. To monitor hydration status, weigh in pre- and post-workout. It is estimated that one needs approximately 20 ounces of fluid to replenish 1-lb of body weight.

A central nervous system stimulant, caffeine may help maintain blood glucose concentration and reduce power loss through its effects on the active musculature and nervous system that reduce fatigue and perceptions of effort, discomfort, and pain. Specific flavors of energy gels and chews are caffeinated at a dose of mg pack.

It is important to experiment with personal tolerance to caffeine as some athletes do not respond favorably to caffeine with symptoms such as a racing heart beat, muscle twitching, stomach distress, and anxiety serving as reason for avoidance. Aim for mg of caffeine e. Avoid consuming more than mg of caffeine on race day.

For best results, consider eliminating caffeine from the diet for 10 days prior to racing.

Background	Just like a race car stores its fuel in a tank, the human body stores carbohydrates as glycogen in both our muscles and liver. These glycogen reserves are relied upon to stabilize blood sugars and allow for optimal muscle function. A single-day or hour carbo-loading protocol may be effective for shorter races, especially if the athlete is training through the race meaning no reduction in training volume is being implemented pre-race. Sample easy-to-digest carbohydrate options include pretzels, plain bagels, bananas, white pasta, white rice, potato, rice-based cereals, sports drinks, and energy bars. Race Morning: Aim for grams of easy-to-digest low fiber carbohydrate in the hours leading up to race start. Be sure to allow 1 hour digestion time for every calories consume. A sample pre-race meal to be consumed in the 2- 3 hours leading up to race start would be a plain bagel topped with a smear of peanut butter and honey plus ounces of sports drink. For example, an lb runner should aim for ~ grams of carbohydrate each hour of training or racing.

Pre-Race: Athletes vulnerable to muscle cramping and fatigue as well as those competing in heat may benefit from increasing salt intake in the few days leading up to race day. A small amount of dark-colored, highly concentrated urine may mean you are dehydrated and need to drink more water. The following tips can help you stay on top of your fluid needs while exercising:. Rehydrate by drinking about 24 ounces of water for every kilogram 2. This helps support optimal performance, both physically and mentally. A quick and easy option is to consume an electrolyte-containing sports drink during the training or event. This can help reduce the risk of developing hyponatremia , which is water intoxication caused by below-normal sodium levels. Some types of protein bars also contain electrolytes. Every athlete will have their own unique fueling and refueling needs and preferences. By experimenting with different approaches, you will find the approach that works best for you. Try various foods and food combinations before, during, and after your workouts. Vary the timing of your food intake and the amount you eat as well and, over time, you will be able to determine your optimal refueling style.

Conflict of Interest The author has no conflict of interest. Home Archive Archive Issue 1 Recent Nutritional Guidelines for Endurance Athletes. DOI: accepted: July published online: January These foods fall into three general categories: carbohydrates, fats, and protein. Carbohydrates are the main nutrients that fuel moderate to high-intensity exercise.

These foods supply the body the glucose it needs for continued and sustained energy. Eating them enables endurance athletes to keep going without " bonking ," in which your blood sugar drops too low and you can't continue.

Yet, research indicates that most non-elite endurance athletes don't consume the necessary amount of carbohydrates to support their hefty training schedule. Fats can also provide energy, mainly when the exercise is low in intensity and longer in duration.

That makes this macronutrient important for supporting training sessions that focus more on endurance than speed. Monounsaturated fats are the best fats from a health standpoint, in that they help increase the body's HDL or "good" cholesterol, reducing the risk of heart attack or stroke.

Adding omega-3 fatty acids reduces inflammation and promotes brain and nervous system function. Proteins are primarily used to maintain and repair muscle. Though not generally thought about as fuel when endurance training, research shows that these types of foods are needed in slightly higher amounts when engaging in this type of exercise.

Think of protein as providing your muscle the strength it needs to keep pushing through. Proteins also help your muscle recover after a grueling training session or competitive event.

Before getting into the best sources of carbs, fat, and protein for endurance athletes, it's important to know when to consume each of these sources for optimal energy and fuel. This can be broken down by pre- and post-training recommendations, as well as suggestions for refueling during an endurance training or event.

Eating three to four hours before engaging in endurance training or events helps the body start off with a full fuel tank. Often referred to as "loading," the best food sources for this pre-training meal are complex carbohydrates , or carbs that take the body longer to digest.

Glycogen stores have a limited supply and get used up rather quickly—within about 90 minutes to two hours—during high-intensity exercise. If not adequately replenished, fatigue sets in and the athlete needs to slow down or risk "hitting the wall.

That's why it is important to consume carbohydrates throughout long training sessions or endurance events. The best carbs for this purpose are simple carbs , or carbs that the body can digest rather quickly.

After the endurance training session or event, the body needs to refill its energy tank. More carbs can assist with this, but protein is important at this point too, providing your muscles the nutrients needed to adequately recover.

Many of the best post-workout snacks provide the carbohydrates needed to rebuild your energy stores. Each category of macronutrients carbs, protein, and fat includes certain foods that offer higher nutritional value, making them better choices for fueling and refueling the body.

Here are a few to consider. Offering a mix of carbohydrate sources, for example, these dietician-recommended energy chews, gels, and bars help provide sustained energy. Since pre-training eating involves consuming complex carbs, healthier foods that fall into this category include:.

To continue high-level exercise for extended periods of time, athletes benefit from fueling their body during the training session with easily digestible or "fast" carbohydrates. Some good mid-exercise refueling options that won't weigh you down include:.

Protein helps the body heal, making it a great after-training food source. Healthier protein food options include:. However, the body does need some fat to function effectively. Fats that are healthier include:.

Just as it is important to know what to eat and when, endurance athletes also benefit from understanding how much to eat. This ensures that you obtain the needed nutrients in the right amount without consuming too many calories and potentially gaining weight.

Intake recommendations for endurance athletes are:  . When calculating your body weight, one kilogram is equal to 2. So, a pound person weighs roughly 68 kilograms divided by 2. If you exercise intensely for more than three or four hours at a time, you need to be mindful of your hydration needs and drink water before, during, and after you exercise.

Don't rely on thirst to tell you when to drink during exercise. By the time you feel thirsty, you're already dehydrated. It's best to drink small amounts often, rather than gulping a lot at once.

Jonathan Cuallenges, RDN, CDCES, CPT is a New York City-based telehealth registered dietitian nutritionist Diabetic foot care tips nutrition communications expert. Ensurance athletes—which include marathon runners and long Nutritional challenges for endurance athletes enddurance and swimmers—have unique sports nutrition requirements. If you exercise at a high intensity for more than two hours per day on most days, the proper diet is essential for optimal performance and recovery.

For example, an lb runner should aim for ~ grams of carbohydrate each hour of training or racing. To maximize carbohydrate uptake into the muscles and extend endurance, choose products whose ingredient lists include multiple types of carbohydrate.

Common carbohydrate sources used in sports foods include maltodextrin, glucose or dextrose, sucrose, and fructose. Common products used on race day include sports drinks, energy gels, energy bars, and energy chews.

Post-Race: Aim for grams of carbohydrate, preferably in liquid form to promote rehydration as well as carbohydrate repletion, as soon as possible upon finishing a hard workout or race effort.

During digestion, protein is broken down into at least individual chemical building blocks known as amino acids that form a little pool within our liver and are used to build muscle, skin, hair, nails, eyes, hormones, enzymes, antibodies, and nerve chemicals.

Some research has found that inclusion of small amounts of protein during prolonged activity can help enhance performance by sparing muscle glycogen as well as aiding fluid uptake.

Protein also can help mute hunger that arises during longer efforts. Athletes on restrictive energy intakes should aim for the high end of this recommendation. Race Morning: Include grams of protein in the hour leading up to race start to help stabilize blood sugars.

Common pre-race protein sources include peanut butter, non-fat milk or yogurt, eggs, and energy bars. During Race: If out on a training or race course longer than 4 hours, aim for up to 5 grams of protein hourly.

Common sources include sports drinks, energy bars, as well as whole food alternatives like turkey jerky and peanut butter sandwiches.

Post-Race: A range of grams of protein taken immediately post-race is sufficient to support muscle repair and immune function post-event. Common sources include milk, meal replacement shakes, and specialized recovery sports drinks. Replacement of electrolytes becomes instrumental in endurance bouts lasting longer than 1 hour, especially when training and racing in hot and humid conditions.
