A Nutrition Strategy Would Have Averted Olympic Agony

The high-stakes case, of the disqualification of Indian woman wrestler Vinesh Phogat from the women’s 50kg wrestling final in the Paris Olympics 2024, was a setback for India. 

Nutrition Strategy Would Have Averted Olympic Agony

• She was found to be 100 grams heavier than permissible limits. 
• This incident highlights the role of support staff including the sports nutritionist, doctors, and the team management in the Indian contingent.
• A myopic view indicates a slip, but the situation highlights the need to integrate precision nutrition in sport. 
• Precision nutrition tailors dietary recommendations based on specific individual requirements, characteristics and circumstances. 
• This process focuses on better understanding and meeting an athlete’s individual requirements, particularly their individual response to different food/supplement intakes and avoiding a one-size-fits-all approach.

The Science

• Precision nutrition involves understanding an individual’s metabolism, microbiome, and how their body responds to food and calorie expenditure to determine the best dietary practices for them. 
• It focuses on systems biology and a multi-omics approach (including genomics, proteomics, metabolomics, microbiomes, and epigenetics), integrated with bioinformatics and machine learning to provide evidence-based individualised nutrition recommendations. 
• This data-driven approach allows for adjustments based on an athlete’s physiological responses, ensuring they are in peak condition for a competition.
• The integration with bioinformatics and machine learning will help in the identification of patterns and predict how different nutritional strategies affect an athlete’s performance. 
• The gut microflora may be influenced by diet, especially a plant-based diet and regular exercise, resulting in the production of short chain fatty acids which may support athletic performance and post-exercise metabolic recovery.
• An effective nutrition recommendation rides on high granularity of an individual’s dietary intake and physical activity data. 
• Traditional questionnaire/interview-based methods of collecting such data have drawbacks such as self-reporting, memory bias, high respondent burden, and socially desirable responses. 
• Combining this subjective information with targeted individual continuous monitoring (for example, continuous blood glucose monitoring) can provide more specific and individualised recommendations for athletes that not only address dietary requirements but also check the regulatory requirements of sport.
• Many wearable sensors track and provide information on physical activity levels, stress, sleep quality, and heart rate monitoring. 
• This incident with Ms. Phogat underscores the importance of continuous and real-time tracking of targeted outcomes for athletes during training sessions, making it easier to achieve and maintain target weight.
