Guidelines for daily carbohydrate intakes have evolved from the "one size fits all" recommendation for a high-carbohydrate diets to an individualized approach to fuel needs based on the athlete's body size and exercise program. More recently, it has been suggested that athletes should train with low carbohydrate stores but restore fuel availability for competition "train low, compete high"based on observations that the intracellular signaling pathways underpinning adaptations to training are enhanced when exercise is undertaken with low glycogen stores. The present literature is limited to studies of "twice a day" training low glycogen for the second session or withholding carbohydrate intake during training sessions.Fueling strategies for athletes -
One of the most important things an athlete can do to maximize performance is to eat a good breakfast. Some breakfast foods you might enjoy are a fruit and yogurt smoothie, breakfast sandwich with egg whites and low-fat cheese, whole grain waffle with almond butter, and oatmeal with skim milk and fruit.
Eat a meal three or four hours before a practice, workout or competition. Choose foods with lots of carbohydrates, such as rice, pasta, potatoes, yogurt, fruit smoothies, vegetables, fruits, crackers, and whole grain breads and rolls.
Watch your fat intake. Eat a snack one hour before a practice, workout or a game that is carbohydrate-based to help top off glycogen stores.
Have an energy bar, banana, bagel or some graham crackers. Wash your snack down with 12 ounces of a sport drink. During breaks, halftime or time-outs drink water or your favorite sport drink. Both water and sports drinks will hydrate you, but a sports drink will give you fuel and electrolytes to help replace sodium that you lose in sweat.
Sports drinks also help keep glycogen stores topped off. Sports drinks are recommended when workouts, practices or competitions last longer than 60 minutes. Weigh yourself before and after workouts and competitions to try to figure out your own personal sweat rate.
Drink cups of sports drink or water for every pound of body weight lost. Eat something within 30 minutes of the end of your practice, workout or game.
This is really important to do if you train hard every day. Muscle glycogen is the primary fuel for energy during exercise and carbohydrate is the primary source of muscle glycogen. A good recovery snack should have carbohydrate and protein value. Low-fat chocolate milk is an ideal recovery drink.
It provides just the right amount of carbohydrates and protein and it's cheap and accessible! Use these basic tips to respect nutrition as an integral part of your training regimen and you will be well on the way to reaching your athletic potential!
These tips are invaluable! I am an athlete and I have been looking at what the best nutrition for an athlete is. So far, your tips have been the most helpful.
Thank you for posting this. Athletes living above the 35th parallel, or those who train and compete indoors, are at the highest risk of deficiency. Supplementation may be warranted in amounts of 2,—5, IUs daily as indicated by lab work.
We know iron deficiency, with or without anemia, reduces muscular function and work capacity, as maximal oxygen uptake will be limited.
Elite athletes, especially females, can be at risk of developing iron deficiency. Where opinions differ is on the use and benefit of antioxidant supplements like tart cherry juice. I do not recommend that my athletes use these antioxidant supplements in the off-season or pre-season when our goal is adaptation, as these supplements could negatively influence it.
Instead, they should be used during the season, potentially in the evening before competition or key training sessions. The role of supplementation in positively impacting speed performance lies in providing energy system fuel, preventing acid-base disturbances, and reducing perceptions of fatigue.
There are four supplements I lean on to help optimize sprint performance:. Supplements should be third-party tested with effectiveness and dosages backed by research.
Creatine is one of the most studied and safest supplements on the market and, in my opinion, the most impactful on performance.
Creatine has been shown to have numerous benefits, but for the purposes of this article, we primarily see performance improvements in repeated bouts of high-intensity exercise with short recovery periods.
Based on our earlier discussion of surrounding energy systems, we know phosphocreatine is the substrate used in the ATP-CP, our main energy system utilized in maximal sprints. Creatine phosphate provides a rapid source of phosphate to resynthesis ADP to ATP. On an omnivorous diet, most individuals will get between 1 and 2 grams of creatine daily found in meat, fish, and eggs.
Supplementation is then recommended to saturate muscular stores. Creatine monohydrate is highly bioavailable and is what I recommend to the athletes I work with.
Creatine can be taken using a loading phase of 20—25 grams. Creatine intake post-training with carbohydrates and protein is found to enhance creatine storage caused by increases in blood flow and the effect of insulin. Caffeine can also help with the release of calcium from the sarcoplasmic reticulum, which we discussed earlier.
Gums with caffeine content, which are increasing in popularity, are absorbed more quickly and could be taken closer to competition.
The half-life of caffeine depends on genetic factors but ranges from 2. This would be most beneficial in sports with repeated high-intensity sprints 1—7 minutes and may not be beneficial in single, maximal sprint events.
Gastrointestinal symptoms are a known side effect of sodium bicarbonate, and tolerance should be tested during non-key training sessions. Splitting the amount into smaller doses spread over the pre-training period may help.
This occurs through the increased synthesis of carnosine, which lowers the ph balance in the muscle by exchanging hydrogen ions for calcium within the muscle, leading to enhanced efficiency of contraction in coupling and excitation. When compared to sodium bicarb, beta-alanine provides more chronic muscular adaptations.
Parathesis is a known side effect of beta-alanine, but it can be reduced by dividing the daily dosage and spreading it throughout the day or using a slow-release capsule. While your competitors obsess over finding the latest and greatest training fad in speed development, get an advantage by making sure that the V8 engine you built during training has the right high-octane fuel to use all that horsepower.
When looking at nutrition for speed development and competition, consider the Fueling Speed Hierarchy: carbohydrates, protein, hydration, micronutrients, and supplementation. Implement a few of these strategies into your training, and let those horses sing!

This article will discuss the five nutritional practices I believe have the biggest impact on helping athletes improve their strength, power, and explosiveness in ways that translate to increases in speed: Ensure sufficient carbohydrate intake.
This fuels our most utilized energy systems and provides the substrate used more directly in speed and explosiveness as the preferred fuel for the brain and central nervous system. Plan adequate protein intake, timing, and dosages.
Doing so will optimize muscle protein synthesis and allow for muscular adaptations to training. This plays a crucial role in muscular contraction, body temperature regulation, and injury prevention. Consume an adequate intake of micronutrients vitamins and minerals.
If dietary protein intake is insufficient, this can result in a loss of protein muscle tissue, because the body will start to break down muscle tissue to meet its energy needs, and may increase the risk of infections and illness. Current recommendations for carbohydrate requirements vary depending on the duration, frequency and intensity of exercise.
More refined carbohydrate foods such as white bread, jams and lollies are useful to boost the total intake of carbohydrate, particularly for very active people.
Athletes are advised to adjust the amount of carbohydrate they consume for fuelling and recovery to suit their exercise level.
For example:. A more recent strategy adopted by some athletes is to train with low body carbohydrate levels and intakes train low.
There is accumulating evidence that carefully planned periods of training with low carbohydrate availability may enhance some of the adaptations in muscle to the training program.
However, currently the benefits of this approach to athletic performance are unclear. The GI has become of increasing interest to athletes in the area of sports nutrition.
However, the particular timing of ingestion of carbohydrate foods with different GIs around exercise might be important. There is a suggestion that low GI foods may be useful before exercise to provide a more sustained energy release, although evidence is not convincing in terms of any resulting performance benefit.
Moderate to high GI foods and fluids may be the most beneficial during exercise and in the early recovery period. However, it is important to remember the type and timing of food eaten should be tailored to personal preferences and to maximise the performance of the particular sport in which the person is involved.
A high-carbohydrate meal 3 to 4 hours before exercise is thought to have a positive effect on performance. A small snack one to 2 hours before exercise may also benefit performance. It is important to ensure good hydration prior to an event.
Consuming approximately ml of fluid in the 2 to 4 hours prior to an event may be a good general strategy to take. Some people may experience a negative response to eating close to exercise.
A meal high in fat, protein or fibre is likely to increase the risk of digestive discomfort. It is recommended that meals just before exercise should be high in carbohydrates as they do not cause gastrointestinal upset.
Liquid meal supplements may also be appropriate, particularly for athletes who suffer from pre-event nerves. For athletes involved in events lasting less than 60 minutes in duration, a mouth rinse with a carbohydrate beverage may be sufficient to help improve performance.
Benefits of this strategy appear to relate to effects on the brain and central nervous system. During exercise lasting more than 60 minutes, an intake of carbohydrate is required to top up blood glucose levels and delay fatigue.
Current recommendations suggest 30 to 60 g of carbohydrate is sufficient, and can be in the form of lollies, sports gels, sports drinks, low-fat muesli and sports bars or sandwiches with white bread. It is important to start your intake early in exercise and to consume regular amounts throughout the exercise period.
It is also important to consume regular fluid during prolonged exercise to avoid dehydration. Sports drinks, diluted fruit juice and water are suitable choices. For people exercising for more than 4 hours, up to 90 grams of carbohydrate per hour is recommended.
Carbohydrate foods and fluids should be consumed after exercise, particularly in the first one to 2 hours after exercise. While consuming sufficient total carbohydrate post-exercise is important, the type of carbohydrate source might also be important, particularly if a second training session or event will occur less than 8 hours later.
In these situations, athletes should choose carbohydrate sources with a high GI for example white bread, white rice, white potatoes in the first half hour or so after exercise.
This should be continued until the normal meal pattern resumes. Since most athletes develop a fluid deficit during exercise, replenishment of fluids post-exercise is also a very important consideration for optimal recovery.
It is recommended that athletes consume 1. Protein is an important part of a training diet and plays a key role in post-exercise recovery and repair.
