Sport-specific nutrition interventions can help an athlete maximize power and endurance, as well as overall health and performance. The intervention includes an assessment of daily eating patterns, optional 3-day dietary analysis, and assessment nutrition tactics used during training and competition, including preparation and recovery.

Through a one-on-one consultation with our sports dietitian, individualized strategies to maximize training and performance are developed. The dietitian also helps the athlete accommodate any specific allergies or chronic health conditions he/she may have. The goal is to help each athlete effectively fuel his/her body for optimal performance and health.
