Nutrition and ice hockey performance

Area of Science:

• Sports Science
• Human Physiology
• Nutrition Science

Background:

• Muscle glycogen is a primary energy source for ice hockey players, with quadriceps muscle glycogen depletion reaching approximately 60% per game.
• Reduced muscle glycogen utilization in successive games suggests potential issues with energy replenishment and sustained performance.
• Dietary habits of professional hockey players may impact their ability to maintain optimal fuel stores.

Purpose of the Study:

• To investigate the dietary patterns of professional ice hockey players during their playing season.
• To assess whether food selection and nutrient intake could be a limiting factor in hockey performance.
• To examine the fuel supply challenges faced by young hockey players in tournament settings.

Main Methods:

• A one-week dietary study was conducted on seven professional hockey players.
• Food selection and intake were analyzed to determine nutritional profiles.
• The study focused on the relationship between diet and the demands of ice hockey performance.

Main Results:

• Professional hockey players exhibited a high protein intake.
• Intake of vegetables and fruits was found to be low among the players studied.
• These dietary patterns raise concerns about adequate fuel supply for performance.

Conclusions:

• The high protein, low fruit and vegetable diet common among hockey players may compromise muscle glycogen replenishment.
• This dietary pattern could negatively affect performance, particularly in situations requiring sustained energy, like multi-game tournaments.
• Addressing nutritional strategies is crucial for optimizing fuel supply and performance in ice hockey athletes.
