Carbohydrates and fluids are the most critical nutrients for elite ice hockey players, according to a 2026 evidence-based review. Players lose approximately 2 liters of sweat per hour during games, and research shows that pre-game carbohydrate intake directly affects performance. Gram Research analysis reveals that protein after games supports muscle recovery, while supplements should only complement—not replace—a solid foundation of real food nutrition.
Elite ice hockey is one of the most demanding sports, requiring players to perform intense bursts of speed and strength while wearing heavy protective gear. A new evidence-based review shows that what hockey players eat directly affects their performance on the ice. The research reveals that carbohydrates and proper hydration are the most critical nutritional factors, followed by adequate protein for muscle recovery. According to Gram Research analysis, players lose significant fluids through sweat during games, making strategic eating and drinking plans essential. The study recommends that players personalize their nutrition based on their training schedule and competition demands, prioritizing real food over supplements whenever possible.
Key Statistics
A 2026 review in the International Journal of Sport Nutrition and Exercise Metabolism found that elite ice hockey players lose approximately 2.02 liters of sweat per hour during games due to high intensity and protective equipment.
Elite male ice hockey players typically cover 2.3 to 6.7 kilometers during their 15-25 minutes of actual on-ice playing time per game, according to the 2026 evidence-based nutrition review.
Research shows that match performance in ice hockey is associated with pre-game muscle glycogen (carbohydrate) content, making pre-game carbohydrate intake a critical performance factor.
The 2026 review identified vitamin D, iron, caffeine, and creatine as potentially beneficial supplements for some elite ice hockey players, though food-based nutrition should be prioritized first.

- Key finding: Carbohydrates and fluids are the most important nutrients for hockey performance, with players losing about 2 liters of sweat per hour during games
- What it means for you: If you play competitive hockey, eating carbs before games and drinking fluids during play can directly improve your performance and endurance on the ice
The Research Details
This was a comprehensive review of scientific research on nutrition for elite ice hockey players. Rather than conducting their own experiment, researchers looked at all the existing studies about what hockey players eat and how it affects their performance. They examined research on energy use during games, carbohydrate needs, fluid loss through sweating, protein requirements for muscle recovery, and the potential benefits of supplements like vitamin D, iron, caffeine, and creatine.
The researchers focused specifically on elite male ice hockey because the sport has unique demands. Hockey involves short, intense bursts of activity (typically 30-80 seconds on the ice) followed by rest periods of 2-5 minutes. Players wear heavy protective equipment that traps heat and increases sweating. The combination of high intensity, frequent position changes, and protective gear creates specific nutritional challenges that differ from other sports.
By reviewing all available evidence, the researchers created practical nutrition guidelines that players and coaches can actually use to improve performance and recovery.
Understanding nutrition for ice hockey is important because the sport’s unique demands—intense bursts of activity combined with heavy protective equipment—create specific nutritional challenges. Unlike steady-state sports like distance running, hockey requires quick energy availability and rapid recovery between shifts. Players need to know exactly what to eat before, during, and after games to maintain their energy levels and mental sharpness throughout three 20-minute periods.
This review was published in a respected sports nutrition journal and synthesizes evidence from multiple studies. However, the researchers noted that energy demands during hockey games haven’t been thoroughly studied, so some recommendations are based on limited direct research. The review provides evidence-based guidelines rather than definitive answers, meaning coaches and players should adapt recommendations to individual needs. The focus on elite male players means findings may not directly apply to female players, younger athletes, or recreational hockey players.
What the Results Show
The research shows that carbohydrates are the primary fuel source during hockey training and games. Elite players typically skate 2.3 to 6.7 kilometers during their 15-25 minutes of actual playing time per game, and this high-intensity activity depletes muscle carbohydrate stores (called glycogen). Studies show that players with higher carbohydrate stores before games perform better, suggesting that pre-game meals should emphasize carbs.
Fluid loss is another critical finding. Players lose approximately 2 liters of sweat per hour during games due to the high intensity of play and the insulating effect of protective equipment. This massive fluid loss can impair performance, concentration, and physical abilities if not managed through strategic drinking during games and recovery periods.
Protein intake after training and games is essential for muscle repair and growth. After intense hockey activity, muscles need protein to rebuild and adapt to the demands placed on them. The review emphasizes that adequate protein supports faster recovery between games and training sessions.
The research also found that while supplements like vitamin D, iron, caffeine, and creatine might help some players, they should never replace a solid foundation of proper food intake. Players should focus on eating real, nutrient-dense foods first and only consider supplements to fill specific gaps.
The review identified several secondary but important findings. First, nutrition plans need to be personalized and adjusted based on the specific demands of different training sessions and games. A practice day requires different nutrition than a game day. Second, the timing of meals matters—eating carbohydrates before games helps maintain energy levels throughout all three periods. Third, recovery nutrition immediately after games is critical for preparing the body for the next competition or training session. The research suggests that individual differences in sweat rate, body size, and metabolic needs mean that cookie-cutter nutrition plans won’t work for all players.
This review builds on decades of sports nutrition research but applies it specifically to ice hockey’s unique demands. Previous research on other sports (like soccer, basketball, and cycling) has established the importance of carbohydrates and hydration, but hockey’s combination of intense bursts, protective equipment, and frequent position changes creates a distinct nutritional profile. The review confirms that general sports nutrition principles apply to hockey while highlighting the sport-specific factors that make hockey players’ nutritional needs different from other athletes.
The researchers acknowledged several important limitations. First, the energy demands during actual hockey games haven’t been thoroughly studied, so some recommendations are based on indirect evidence from similar sports. Second, most research on hockey nutrition focuses on male players, so the findings may not fully apply to female hockey players, who may have different nutritional needs. Third, the review focuses on elite players, so recommendations may need adjustment for recreational or youth hockey players. Finally, while some supplements show promise, research specifically on hockey players using these supplements is limited, so recommendations are based on general sports science rather than hockey-specific studies.
The Bottom Line
Elite hockey players should prioritize carbohydrate intake before games and training sessions to maintain energy levels (high confidence). Players should drink fluids consistently during games to replace sweat losses of approximately 2 liters per hour (high confidence). After games and training, players should consume adequate protein to support muscle recovery (high confidence). Nutrition plans should be personalized based on individual body size, sweat rate, and training schedule rather than following a one-size-fits-all approach (high confidence). Supplements like vitamin D, iron, caffeine, and creatine may benefit some players but should only be considered after establishing solid nutrition fundamentals with real food (moderate confidence).
These recommendations are most directly applicable to elite male ice hockey players competing at high levels. Coaches, athletic trainers, and sports nutritionists working with hockey teams should use these guidelines to develop individualized nutrition plans. Female hockey players, youth players, and recreational players should adapt these principles to their specific needs, as the research focuses on elite males. Players with specific health conditions or dietary restrictions should work with a sports nutritionist to personalize these recommendations.
Players may notice improved energy levels and performance within 1-2 weeks of implementing proper pre-game carbohydrate loading and hydration strategies. Muscle recovery improvements typically become apparent within 2-4 weeks of consistent post-game protein intake. Long-term benefits like improved endurance and reduced injury risk develop over months of consistent nutrition practices. Individual results vary based on how well players adhere to personalized nutrition plans and their baseline nutrition status.
Frequently Asked Questions
