Nutritionally Relevant Technological Advancements in Professional Cycling.

Area of Science:

• Sports Science
• Exercise Physiology
• Nutritional Science

Background:

• Technological advancements provide cyclists with performance data.
• This data can inform personalized nutrition strategies for improved cycling performance.
• The utility of this data hinges on its quality, interpretation, and practical application.

Purpose of the Study:

• To review current and emerging technologies used in professional cycling.
• To critically evaluate the validity and reliability of these technologies for informing nutritional strategies.
• To discuss the practical utility and rationale for using these technologies in sports nutrition.

Main Methods:

• Review of existing literature on performance-enhancing technologies in cycling.
• Critical evaluation of the scientific evidence for the validity and reliability of selected technologies.
• Discussion of the potential and limitations of these technologies for guiding nutritional interventions.

Main Results:

• Technologies like power meters offer valid data for energy expenditure calculations.
• Other technologies, such as continuous glucose monitors and portable analyzers, show variable validity and reliability.
• Some technologies lack sufficient evidence or rationale for informing nutritional strategies effectively.

Conclusions:

• Certain technologies (e.g., power meters) are sufficiently valid and reliable to inform specific nutritional strategies.
• Other technologies require further research to establish their validity and practical utility.
• Practitioners should carefully assess the practical value, validity, and reliability of any technology before implementing it for athlete support.
