Sports nutrition is the foundation of athletic success. It is a well-designed nutrition plan that allows active adults and athletes to perform at their best. It supplies the right food type, energy, nutrients, and fluids to keep the body well hydrated and functioning at peak levels.

A sports nutrition diet may vary day to day, depending on specific energy demands. The energy required for living and physical activity comes from the food we eat and fluid intake. Macronutrients in the following food groups supply the energy essential to optimal body function.

Carbohydrates are either simple or complex, and the most important energy source for the human body. Simple carbs include sugars naturally occurring in foods like fruits, vegetables, and milk. Whole grain bread, potatoes, most vegetables, and oats are examples of healthy complex carbs.

Your digestive system breaks down carbohydrates into glucose or blood sugar which feeds energy to your cells, tissues, and organs.

Proteins are made up of a chain of amino acids and are essential to every cell of the human body. Protein can either be complete or incomplete.

A complete protein contains all the amino acids needed by the body, and include animal sources like meat, fish, poultry, and milk. Incomplete protein sources typically plant-based proteins often lack one or more of the essential amino acids.

Essential amino acids can't be made by the body and must be supplied by food. Protein plays an important role in muscle recovery and growth. Those with higher protein needs might benefit from using one of these dietician recommended whey protein powders.

Fats can be saturated or unsaturated, and they play a vital role in the human body. Unsaturated fats are considered healthy and come from plant sources like olive oil and nuts. Saturated fats are found in animal products like red meats and high-fat dairy, which are indicated to increase the risk of disease.

Healthy fats provide energy, help with body development, protect our organs, and maintain cell membranes. Active adults and competitive athletes turn to sports nutrition to help them achieve their goals. Examples of individual goals could include gaining lean mass, improving body composition, or enhancing athletic performance.

These sport-specific scenarios require different nutritional programs. Research findings indicate the right food type, caloric intake, nutrient timing, fluids, and supplementation are essential and specific to each individual.

Training programs require a well-designed diet for active adults and competitive athletes. Research shows a balanced nutrition plan should include sufficient calories and healthy macronutrients to optimize athletic performance. The body will use carbohydrates or fats as the main energy source, depending on exercise intensity and duration.

Inadequate caloric intake can impede athletic training and performance. Active adults exercising three to four times weekly can usually meet nutritional needs through a normal healthy diet. Moderate to elite athletes performing intense training five to six times weekly will require significantly more nutrients to support energy demands.

For example, and according to research, energy expenditure for extreme cyclists competing in the Tour de France is approximately 12, calories per day.

Endurance programs are defined as one to three hours per day of moderate to high-intensity exercise. High-energy intake in the form of carbohydrates is essential. According to research, target carbohydrate consumption for endurance athletes ranges from 6g to 10g per kilogram of body weight per day.

Fat is a secondary source of energy used during long-duration training sessions. Endurance athletes are more at risk for dehydration. Replacing fluids and electrolytes lost through sweat are necessary for peak performance.

Resistance training programs are designed to gradually build the strength of skeletal muscle. Strength training is high-intensity work. It requires sufficient amounts of all macronutrients for muscle development. Protein intake is especially vital to increase and maintain lean body mass.

Research indicates protein requirements can vary from 1. Preparing for a competitive sport will vary in sports nutrition requirements. For example, strength athletes strive to increase lean mass and body size for their sport. Athletic goals will determine the best sports nutrition strategy.

Pre and post-workout meal planning are unique for each athlete and essential for optimal performance. Adequate hydration and electrolytes are essential for health and athletic performance. We all lose water throughout the day, but active adults and athletes lose additional body water and a significant amount of sodium sweating during intense workouts.

Dehydration is the process of losing body water, and fluid deficits greater than 2 percent of body weight can compromise the athletic performance and cognitive function. Athletes are recommended to use fluid replacement strategies as part of their sports nutrition to maintain optimal body functioning.

Rehydration with water and sports drinks containing sodium are often consumed depending on the athlete and sporting event. Lack of sufficient hydration for athletes may lead to the following:  . Sports supplements and foods are unregulated products marketed to enhance athletic performance. There are limited supplements backed by clinical research.

The Australian Institute of Sport has provided a general guide ranking sports performance supplements and foods according to the significance of scientific evidence:.

In OctoberPresident Clinton sporgs DSHEA into law. This statute was enacted amid claims that the Food and Drug Administration FDA was distorting the then-existing provisions Overciew the Nuteition, Drug, and Sstudies Act FDCA to improperly deprive Overveiw public of safe and Thermogenic fat burning blend dietary supplement products.

Further, dietary ingredients may also include extracts, metabolites, or concentrates of those Wound healing remedies. Dietary supplements may Overgiew Overview of sports nutrition research and studies in many stduies such Overfiew tablets, capsules, softgels, gelcaps, liquids, or powders, but researvh only be intended for oral ingestion.

Dietary supplements cannot be marketed or promoted for sublingual, intranasal, transdermal, injected, or in any other route of administration except oral ingestion. A supplement can be in other forms, such as a bar, as long as the information on its label does not represent the product as a conventional food or a sole item of a meal or diet.

Additionally, and contrary to widespread opinion, DSHEA did not leave the industry unregulated. The dietary supplement industry is in fact regulated by the FDA as a result of DSHEA. The law ensures the authority of the FDA to provide legitimate protections for the public health. The Federal Trade Commission FTC also continues to have jurisdiction over the marketing claims that dietary supplement manufacturers or companies make about their products.

The FDA and FTC operate in a cooperative fashion to regulate the dietary supplement industry. In this respect, the extent to which information is shared and jurisdiction between these two entities overlaps with regard to marketing and advertising dietary supplements continues to increase.

In the United States, dietary supplements are classified as food products, not drugs, and there is generally no mandate to register products with the FDA or obtain FDA approval before producing or selling supplements to consumers.

However, if a dietary supplement manufacturer is making a claim about their product, the company must submit the claims to FDA within 30 days of marketing the product.

Compare this, for example, with Canada where under the Natural Health Product NHP Regulations enacted in supplements must be reviewed, approved, and registered with Health Canada. The rationale for the U. model is based on a presumed long history of safe use; hence there is no need to require additional safety data.

This product is not intended to diagnose, treat, cure, or prevent any disease. Although many dietary ingredients have been introduced into dietary supplements since October and have not been submitted to the FDA for a safety review, nutritional supplementation writ large is generally safe.

Perhaps more alarming is a report by the Centers for Disease Control suggesting 2, emergency room visits were due to prescription drug-related events which dwarfs the emergency room visits due to dietary supplements adjusted from 23, visits after excluding cases of older adults choking on pills, allergic reactions, unsupervised children consuming too many vitamins, and persons consuming ingredients not defined by DSHEA as a dietary supplement [ 5 ].

Furthermore, a recent Healthcare Cost and Utilization Project Statistical Brief by Lucado et al. Notwithstanding, there have been case reports of liver and kidney toxicity potentially caused by supplements containing herbal extracts [ 7 ] as well as overdoses associated with pure caffeine anhydrous ingestion [ 8 ].

Collectively, the aforementioned statistics and case reports demonstrate that while generally safe, as with food or prescription drug consumption, dietary supplement consumption can lead to adverse events in spite of DSHEA and current FDA regulations described below.

Recognizing that new and untested dietary supplement products may pose unknown health issues, DSHEA distinguishes between products containing dietary ingredients that were already on the market and products containing new dietary ingredients that were not marketed prior to the enactment of the law.

DSHEA grants the FDA greater control over supplements containing NDIs. The first criterion is silent as to how and by whom presence in the food supply as food articles without chemical alteration is to be established.

The second criterion—applicable only to new dietary ingredients that have not been present in the food supply—requires manufacturers and distributors of the product to take certain actions.

The guidance prompted great controversy, and FDA agreed to issue a revised draft guidance to address some of the issues raised by industry. In AugustFDA released a revised Draft Guidance that replaced the Draft Guidance. The purpose of the Draft Guidance was to help manufacturers and distributors decide whether to submit a premarket safety notification to FDA, help prepare NDI notifications in a manner that allows FDA to review and respond more efficiently and quickly, and to improve the quality of NDI notifications.

The Draft Guidance has been criticized by industry and trade associations for its lack of clarity and other problems. Some of these issues include the lack of clarity regarding Pre-DSHEA, Grandfatheredingredients and FDA requiring an NDI notification even if another manufacturer has submitted a notification.

Self-Affirmed GRAS is when a company has a team of scientific experts evaluate the safety of their ingredient. There is no requirement that the safety dossier be submitted to FDA but is used by the company as an internal document that may be relied upon if the ingredient is challenged by the FDA.

FDA has expressed its concern with this practice and does not encourage dietary supplement manufacturers to use Self-Affirmed GRAS to avoid submitting NDI notifications.

In any event, the likelihood of another revised Draft Guidance from FDA becoming available in the future is high, and possibly more enforcement actions taken against companies that market an NDI without submitting a notification. In response to growing criticism of the dietary supplement industry, the th Congress passed the first mandatory Adverse Event Reporting AER legislation for the dietary supplement industry.

In DecemberPresident Bush signed into law the Dietary Supplement and Nonprescription Drug Consumer Protection Act, which took effect on December 22, After much debate in Congress and input from the FDA, the American Medical Association AMAmany of the major supplement trade associations, and a host of others all agreed that the legislation was necessary and the final version was approved by all.

The law strengthens the regulatory structure for dietary supplements and builds greater consumer confidence, as consumers have a right to expect that if they report a serious adverse event to a dietary supplement marketer the FDA will be advised about it.

An adverse event is any health-related event associated with the use of a dietary supplement that is adverse.

A serious adverse event is an adverse event that A results in i death, ii a life-threatening experience, iii inpatient hospitalization, iv a persistent or significant disability or incapacity, or v a congenital anomaly or birth defect; or B requires, based on reasonable medical judgment, a medical or surgical intervention to prevent an outcome described under subparagraph A.

Once it is determined that a serious adverse event has occurred, the manufacturer, packer, or distributor responsible person of a dietary supplement whose name appears on the label of the supplement shall submit to the Secretary of Health and Human Services any report received of the serious adverse event accompanied by a copy of the label on or within the retail packaging of the dietary supplement.

The responsible person has 15 business days to submit the report to FDA after being notified of the serious adverse event. Following the initial report, the responsible person must submit follow-up reports of new medical information that they receive for one-year.

The FDA has various options to protect consumers from unsafe supplements. The FDA also has the authority to protect consumers from dietary supplements that do not present an imminent hazard to the public but do present certain risks of illness or injury to consumers.

The law prohibits introducing adulterated products into interstate commerce. The standard does not require proof that consumers have actually been harmed or even that a product will harm anyone. It was under this provision that the FDA concluded that dietary supplements containing ephedra, androstenedione, and DMAA presented an unreasonable risk.

Most recently, FDA imposed an importation ban on the botanical Mitragyna speciose, better known as Kratom. InFDA issued Import Alert 54—15, which allows for detention without physical examination of dietary supplements and bulk dietary ingredients that are, or contain, Kratom. Criminal penalties are present for a conviction of introducing adulterated supplement products into interstate commerce.

While the harms associated with dietary supplements may pale in comparison to those linked to prescription drugs, recent pronouncements from the U.

Department of Justice confirm that the supplement industry is being watched vigilantly to protect the health and safety of the American public. When DSHEA was passed init contained a provision requiring that the FDA establish and enforce current Good Manufacturing Practices cGMPs for dietary supplements.

However, it was not until that the cGMPs were finally approved, and not until that the cGMPs applied across the industry, to large and small companies alike. The adherence to cGMPs has helped protect against contamination issues and should serve to improve consumer confidence in dietary supplements.

The market improved as companies became compliant with cGMPs, as these regulations imposed more stringent requirements such as Vendor Certification, Document Control Procedures, and Identity Testing.

These compliance criteria addressed the problems that had damaged the reputation of the industry with a focus on quality control, record keeping, and documentation.

However, it does appear that some within the industry continue to struggle with compliance. In Fiscal Yearit was reported that approximately Further, Undoubtedly, relying on certificates of analysis from the raw materials supplier without further testing, or failing to conduct identity testing of a finished product, can result in the creation of a product that contains something it should not contain such as synthetic chemicals or even pharmaceutical drugs.

All members of the industry need to ensure compliance with cGMPs. According to the Nutrition Labeling and Education Act NLEAthe FDA can review and approve health claims claims describing the relationship between a food substance and a reduced risk of a disease or health-related condition for dietary ingredients and foods.

However, since the law was passed it has only approved a few claims. The delay in reviewing health claims of dietary supplement ingredients resulted in a lawsuit, Pearson v.

Introduction	Haakonssen, E. Further, dietary ingredients may also include extracts, metabolites, or concentrates of those substances. To this point, Brilla and Conte [ ] did report depletions of both zinc and magnesium, thus increases in testosterone levels could have been attributed to deificient nutritional status rather than a pharmacologic effect.

Actions for this page	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. Protein needs are generally met and often exceeded by most athletes who consume sufficient energy in their diet. The amount of protein recommended for sporting people is only slightly higher than that recommended for the general public. For athletes interested in increasing lean mass or muscle protein synthesis, consumption of a high-quality protein source such as whey protein or milk containing around 20 to 25 g protein in close proximity to exercise for example, within the period immediately to 2 hours after exercise may be beneficial. As a general approach to achieving optimal protein intakes, it is suggested to space out protein intake fairly evenly over the course of a day, for instance around 25 to 30 g protein every 3 to 5 hours, including as part of regular meals. There is currently a lack of evidence to show that protein supplements directly improve athletic performance. Therefore, for most athletes, additional protein supplements are unlikely to improve sport performance. A well-planned diet will meet your vitamin and mineral needs. Supplements will only be of any benefit if your diet is inadequate or you have a diagnosed deficiency, such as an iron or calcium deficiency. There is no evidence that extra doses of vitamins improve sporting performance. Nutritional supplements can be found in pill, tablet, capsule, powder or liquid form, and cover a broad range of products including:. Before using supplements, you should consider what else you can do to improve your sporting performance — diet, training and lifestyle changes are all more proven and cost effective ways to improve your performance. Relatively few supplements that claim performance benefits are supported by sound scientific evidence. Use of vitamin and mineral supplements is also potentially dangerous. Supplements should not be taken without the advice of a qualified health professional. The ethical use of sports supplements is a personal choice by athletes, and it remains controversial. If taking supplements, you are also at risk of committing an anti-doping rule violation no matter what level of sport you play. Dehydration can impair athletic performance and, in extreme cases, may lead to collapse and even death. Drinking plenty of fluids before, during and after exercise is very important. Fluid intake is particularly important for events lasting more than 60 minutes, of high intensity or in warm conditions. 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.
