Nutrition and elite young athletes
Medicine and Sport Science
|December 24, 2010
Summary
Young athletes need specific nutrition for growth and performance, with unique metabolic needs differing from adults. More research is vital for tailored sports nutrition guidance for this group.
Area of Science:
- Sports Nutrition
- Pediatric Exercise Science
- Human Metabolism
Background:
- Elite young athletes require optimal nutrition for growth, development, and peak exercise performance.
- Unique metabolic characteristics in children and adolescents, such as fuel utilization and glycogen storage, necessitate distinct nutritional considerations compared to adult athletes.
- Current sports nutrition recommendations for young athletes are often extrapolated from adult data, highlighting a need for sport-specific research.
Purpose of the Study:
- To explore the role of nutrition in the health and exercise performance of elite young athletes.
- To identify key metabolic differences between young and adult athletes that influence nutritional requirements.
- To assess the current state of sports nutrition advice for young athletes and identify research gaps.
Main Methods:
- Review of existing literature on pediatric sports nutrition and exercise metabolism.
- Comparison of metabolic responses to exercise in children and adolescents versus adults.
- Analysis of current recommendations and evidence regarding energy and fluid intake during exercise for young athletes.
Main Results:
- Young athletes exhibit distinct metabolic profiles, including greater reliance on fat oxidation and smaller glycogen stores, suggesting potentially different carbohydrate needs.
- Thermoregulation differences exist, but their precise impact on fluid requirements remains unclear.
- While exogenous carbohydrate oxidation rates may appear higher in children, this is likely due to lower absolute exercise intensities, with absorption rates comparable to adults.
Conclusions:
- Elite young athletes have unique nutritional requirements influenced by their developmental stage and metabolic differences.
- Current sports nutrition guidelines for young athletes require refinement, as they are largely based on adult data.
- Further research is essential to develop evidence-based, individualized nutrition strategies for optimizing the health and performance of elite young athletes.

01:28Proteins: Dietary Sources and Requirements
Consuming animal-based products offers high-quality proteins that contain optimal levels and combinations of essential amino acids, crucial for tissue repair and growth. Foods like eggs, milk, fish, and most meats are a source of complete proteins. Legumes and cereals are abundant in proteins; however, they typically lack a full range of essential amino acids. As a result, they are considered incomplete protein sources. Some plant sources like soybeans, quinoa, and amaranth do contain complete...
01:27Parentral Nutrition: Centeral and Peripheral Parental Nutrition
Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...

01:21Overview of Protein Metabolism
Proteins are broken down into amino acids during digestion. Unlike fats and carbohydrates, which are stored for later use, proteins are not. Instead, amino acids are either used to produce ATP through oxidation or contribute to the creation of new proteins for the growth and repair of the body. Any surplus amino acids from the diet are converted into glucose or triglycerides rather than excreted.
Amino acids play various roles in the body once they are absorbed into cells. They are restructured...

02:35Key Elements for Plant Nutrition
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the atmosphere, the...
01:28Chronic Kidney Disease III: Interprofessional Care
Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...
01:27Exercise and Muscle Performance
Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...
