The Use of Nutrigenomics in Sports Nutrition

Not Applicable

• Conditions: Nutrigenomics; Sport Nutrition
• Interventions: Other: Genetic based dietary advice; Other: Personalised population based dietary advice

• Registration Number: NCT04914156
• Lead Sponsor: University of Auckland, New Zealand

Brief Summary

The study's aim is to determine if nutrigenomics-based dietary advice is a greater motivator for dietary change amongst an athlete population. Specifically, the investigators will be examining whether nutrigenomics-based personalized dietary advice results in greater changes in dietary intake and body composition amongst athletes compared to personalised population-based sports nutrition advice. It is hypothesized that the Nutrigenomics in Sports Nutrition group would engage in greater dietary changes and better adhere to the dietary advice compared to the standard advice group.

Arm && Interventions

Group	Intervention	Description
Personalised, genetic-based advice for sport performance	Genetic based dietary advice	This group will receive personalised nutrition advice for sports performance based on their genetic test results and tailored to their current dietary intake.
Personalised nutrition advice for sport performance based on population-based evidence	Personalised population based dietary advice	This group will receive personalised nutrition advice on key nutrients relating to sports performance based on current best practice, population-based sport nutrition guidelines. These will be tailored to their current dietary intake

Primary Outcome Measures

Name	Time	Method
Changes in dietary intake from baseline	8 weeks	We will assess dietary intake for energy intake, carbohydrates, protein, fat, sodium, caffeine, glycemic index, iron, Vitamin A, Vitamin B12, Vitamin C, Vitamin D, Vitamin E, Folate and Calcium using a 3 day food record conducted at baseline using Easy Diet Diary phone application. A second 3 day food record will be conducted post intervention period to examine any changes in dietary habits.

Secondary Outcome Measures

Name	Time	Method
Changes in body composition from baseline	8 weeks	At baseline, participants will indicate body composition goals and baseline body composition measurements will be taken using International Society for Advancement of Kinanthropometry accredited guidelines. Repeated body composition measurements will be taken post intervention to examine in any changes in body composition.
