Ice Hockey Energy Demands
Ice hockey players burn 1500–2500 kcal per game. One shift lasts 45–90 seconds — during that time heart rate reaches 85–95% of maximum. During a game, a player performs 15–25 such shifts.
🔥 Calorie Deficit
The average ice hockey player loses 2–5 kg of muscle mass per season if nutrition is not optimized. Calorie requirement: 3500–5000 kcal/day.
⏱️ Shift Cycle
45–90 sec of maximum intensity → 2–4 min of rest. The anaerobic system dominates, so creatine phosphate and glycogen are the main fuel sources.
💧 Dehydration
Despite the cold, ice hockey players sweat heavily under their equipment. 2–4 liters of fluid are lost per game. Dehydration reduces explosive power.
🥶 Effects of Cold
In the cold, the body burns extra calories to maintain body temperature. Nutrition must compensate for this with +10–15% calories.
