This document provides an overview of modeling approaches that can be applied in the NHL to improve player performance. It discusses periodization and monitoring to develop winning designs. Examples are given from other sports like bobsleigh and Formula 1 that utilize engineering models. The document then focuses on specific modeling areas for the NHL, including increasing momentum, aerobic output, durability and reducing recovery time and injury risk. Microbiome modeling and resisted speed training on land and ice are also discussed. Intervention hierarchies and fiber type adaptations are addressed. Finally, NHL-specific windows are outlined around travel, stress, nutrition, equipment, diagnostics and managing power and work.
