Abstract Background In this Position Statement, the International Society of Sports Nutrition ISSN provides an objective and critical review of the literature pertinent to nutritional considerations for training and racing in single-stage ultra-marathon.
Background Ultra-marathons are footraces that exceed the traditional marathon distance of Evidence statements This Position Stand is concerned primarily with the nutritional considerations for single-stage ultra-marathon training and racing. Table 1 Grading system and evidence strategies Full size table.
Considerations for training Energy and macronutrient demands The foremost nutritional challenge facing the ultra-marathon runner is meeting the daily caloric demands necessary to optimize recovery and permit prolonged and repeated training sessions [ 24 ]. Considerations for racing Energy and macronutrient demands Energy expenditure Given the durations typical of ultra-marathon, it is not feasible to meet caloric demands in their entirety.
Energy intake Field studies indicate that successful completion of ultra-marathon is generally associated with greater energy and fluid intake [ 14 , 15 ], even when accounting for variations in performance time [ 15 ]. Carbohydrate versus fat intake The mechanistic link between glycogen depletion in skeletal muscle and liver, and a subsequent early-onset fatigue during prolonged exercise was made in the s [ 98 ].
Summary Ultra-marathon is a rapidly-growing sport contested by amateur and elite athletes the world-over. Availability of data and materials Not applicable.

First, the loss of muscle mass means you may lose functionality, ie you may be unable to lift groceries like you used to.
It also can result in changes in balance and stability which may lead to increased risk of falls. Lastly, because our muscle mass is a metabolically active tissue ie it stores and burns carbohydrates and fats the decreased muscle mass can decrease the metabolic efficiency and storage of carbohydrates and fats and can lead to development of chronic diseases such as cardiovascular disease or type 2 diabetes.
This results in a huge stress on our health care system and therefore it is important for us to think about nutrition strategies to maintain our muscle mass as we age.
Either way, we can have higher muscle breakdown than build up, and thus a loss of lean tissue. The first point I want to make is not related to nutrition. It is well known that resistance training is a VERY powerful stimulus of muscle building capacity and aged muscles respond to resistance training similar to young muscles.
Resistance training in combination with very easy nutrition changes can help retain, maintain and possibly even build muscle mass in older adults. In a westernized country like Canada, we often get enough protein, however I do notice that older athletes or adults may still need to bump up their intake to maximize recovery.
The reason for this recommendation is because we know that an older adult will not respond to a 20g dose of protein like a younger person would, and a higher dose of protein is needed to stimulate muscle building.
Some older adults experience decreased appetite and will reduce portions, leading to lower overall protein intake. We need to remember that our protein needs are higher compared to when we were young! Research does show that soy protein vs whey or beef protein is less effective to stimulate muscle building.
Even though soy is a complete protein has the same amino acid make up as meat it seems as though it is processed differently in the body. Mainly, the protein in soy seems to be digested slower resulting in less of an increase in amino acid levels in the blood and thus decreased stimulation of muscle protein synthesis.
Very careful nutrition planning is necessary if you are an older adult who adheres to a vegetarian or vegan diet. Dairy has the amino acid Leucine, which is a branch chain amino acid.
It is a potent stimulator of muscle build up and can assist in maintaining lean mass. Not only is dairy a source of leucine, but adding a cup of milk cow or soy only to your meal will add about 8g of protein, which actually could be all the changes you need to make to meet the protein needs at your breakfast, lunch and dinner.
In addition, consuming dairy products will provide you with calcium and vitamin D to assist in prevention of osteoporosis! Win win right?! We talked about the amount of protein, and the quality and now we get to the timing!
If we look at typical protein amounts at each meal of the general population, we typically consume very little protein at breakfast, moderate amounts at lunch and a HUGE portion at dinner.
This is a very skewed distribution of your protein and very little protein synthesis occurs until the dinner time, where not all of that protein can even be used and is therefore wasted.
Having multiple doses throughout the day at regular time intervals is the best method of feeding and maintaining your muscle mass.
You also want to make sure you place your protein at appropriate times to ensure adequate recovery from exercise bouts. If you are an older adult who is engaging in regular exercise, supplements like protein powder might be common place in your dietary plan.
One other supplement that has been shown to have some benefits for older adults is creatine. First we must understand that the muscle stores phosphocreatine and it is a substrate that can quickly and easily be used to provide energy for activity lasting only seconds.
The second is that it is an anabolic stimulant, meaning the higher storage of creatine results in increased muscle protein synthesis and growth. Carbohydrates are not just for endurance athletes, short duration events also require glycogen stores to fuel performance. Timing of fueling, loading and refueling also play key roles.
Protein Research over the last years now indicates that athletes engaged in higher intensity exercise need to consume more than the Recommended Daily Allowance RDA of protein which was the former way of thinking, perhaps even twice as much.
Dietary protein promotes greater adaptation to training and low protein intake may reduce training outcomes and slow recovery. Different types of proteins are ingested at different rates and have different properties, so a nutritional plan should be made to make sure it includes enough protein that is high quality.
The best dietary sources of low fat, high quality protein are light skinless chicken, fish, egg white and skim milk casein and whey. Fat Dietary recommendations for fat are the same or slightly higher for athletes than the average person.
In general, research suggests that high-fat diets does not enhance performance, however, reducing fat intake in an effort to lose weight or improve body composition often means reducing the absorption of essential nutrients.
Vitamins Vitamins are essential organic compounds that serve to regulate metabolic processes, energy synthesis, neurological processes, and prevent destruction of cells.
Consuming the recommended daily amounts can help maintain general health. While vitamins in and of themselves do not have direct performance enhancing properties, consuming RDA amounts may help athletes tolerate training better by reducing oxidative stress vitamin E, C and boost the immune system vitamin C , which may lead to greater tolerance for heavier training.
Minerals Minerals serve as structure for tissue, important components of enzymes and hormones, and regulators of metabolic and neural control.
Unlike with vitamins, dietary supplementation of certain minerals can improve exercise capacity. Some of the more impactful minerals include calcium, iron, sodium phosphate, salt, and zinc.
Water Most, if not all, athletes understand the importance of drinking before, during and after athletic exertion.

In Nutritional considerations for older endurance athletes, our society is becoming more health olde, which is fr People are living longer and want to feel younger as they age. I often work with aging athletes, and older adults to help provide guidance on how they can use different nutrition strategies to help them reach their goals, whether health or fitness related. Some common issues I find older adults face include recovery, strength and body composition changes.

Athletes have different nutritional needs than the general population in order to support their vigorous activity levels in both practice and competition. Energy needs for athletes increase depending on their energy expenditure. The amount of energy expended during physical activity is contingent on the intensity, duration, and frequency of the exercise. Competitive athletes may need 3, to over 5, calories daily compared to a typical inactive individual who needs about 2, calories per day. Weight-bearing exercises, such as running, burn more calories per hour than non-weight-bearing exercises, such as swimming, since weight-bearing exercises require your body to move against gravity.
