Why in News?

Vinesh Phogat's disqualification from the Paris Olympics 2024 for being 100 grams overweight underscores the urgent need for integrating precision nutrition into Indian sports training to prevent such issues and enhance performance.

Meaning of Precision Nutrition

• Precision nutrition tailors dietary recommendations based on an individual's specific requirements, characteristics, and circumstances. 
• It focuses on better understanding and meeting an athlete's individual needs and responses to different food and supplement intakes.
• This approach avoids a one-size-fits-all strategy and aims to optimize athlete performance while prioritizing their health and well-being.

The Science Behind Precision Nutrition

• Systems Biology and Multi-Omics Approach: Precision nutrition relies on systems biology and a multi-omics approach, which includes genomics, proteomics, metabolomics, microbiomes, and epigenetics. This data-driven method uses bioinformatics and machine learning to offer personalized dietary recommendations based on detailed physiological data.
• Bioinformatics and Machine Learning: Integration with bioinformatics and machine learning helps identify patterns and predict how different nutritional strategies impact an athlete’s performance. This approach allows for real-time adjustments based on physiological responses to optimize outcomes.
• Gut Microflora and Athletic Performance: The composition of gut microflora (the trillions of microorganisms in the digestive tract that influence nutrient metabolism, immunity, and health) influenced by diet and exercise affects athletic performance and metabolic recovery. Precision nutrition can enhance performance by optimizing gut health and nutrient absorption.

Challenges with Traditional Methods

• Drawbacks of Current Data Collection: Traditional methods of dietary data collection, such as questionnaires and interviews, often suffer from issues like self-reporting bias, memory lapses, and social desirability. These methods are less effective in providing accurate and comprehensive data for precision nutrition.
• Advancements in Monitoring: Continuous and real-time monitoring through wearable sensors and devices like continuous glucose monitors (CGMs) offers a more accurate picture of an athlete’s physiological state. This technology helps track physical activity, stress levels, sleep quality, and metabolic responses, leading to more precise dietary recommendations.

Role of Continuous Glucose Monitors (CGMs)

• Function and Benefits: CGMs are devices that continuously monitor blood glucose levels. They provide minute-by-minute data on glucose levels, helping create personalized nutrition plans. For athletes, CGMs can manage energy levels, build muscle, and maintain body weight effectively.
• Examples of Success: Athletes like Chelsea Hodges and Eliud Kipchoge have utilized CGMs to enhance their training and performance. While the Union Cycliste Internationale (the world governing body of cycling and recognised by the International Olympic Committee) has banned CGMs during competitions, their use during training sessions could provide valuable insights into how different foods affect athletic performance.

Importance of Precision Nutrition in Weight-Based Sports

• Challenges in Weight-Based Sports: In weight-based sports such as wrestling, boxing, and martial arts, athletes often engage in extreme measures to meet weight requirements. This can include dehydration, starvation, and other drastic methods that negatively impact their health and performance.
• Need for Precision Nutrition: Precision nutrition can help athletes in these sports manage their weight more effectively and healthily, avoiding the extreme and often harmful methods currently employed. By providing tailored dietary plans and continuous monitoring, precision nutrition can support athletes in maintaining their weight class without compromising their performance or health.

Role of Sports Nutritionists

• Training and Involvement: Sports nutritionists trained in precision nutrition are crucial for monitoring and adjusting dietary plans based on an athlete’s specific needs. They must also be well-versed in the sport's rules and regulations, including weight categories and weigh-in procedures, to provide effective guidance.
• Long-Term Engagement: For optimal results, nutritionists should work with athletes over extended periods, tracking their responses to dietary adjustments and refining recommendations as needed. This long-term involvement helps manage athletes’ dietary needs throughout their training cycles and competitive seasons.

Conclusion

Vinesh Phogat's disqualification reveals significant gaps in India's sports support system, emphasizing the necessity for precision nutrition. By leveraging technology and expert nutritionists, India can enhance athlete training, helping them achieve their full potential while prioritizing health and preventing future performance setbacks.
