Training
You never know what each game has in store for you. That's why it's wise to be prepared for different situations by making sure your training is varied and challenges all the different muscle groups and energy systems. Change between cardio, strength training, and technique training, and see to it that you focus on the areas that need improvement the most.
Nutrition
Make sure to have several meals during the day. While the food you eat should be rich in carbohydrates, proteins and fat, it is important to avoid ingesting fatty foods just before or after training and matches, as it will interfere with digestion and blood flow. Always stay hydrated. Some sports entail rather harsh conditions due to weather or the use of special outfits and protective gear. Keep water with you at all times and drink even if you are not thirsty, to prevent dehydration.
Supplementation
Use supplements according to your needs. Taking care of joints and preserving muscle mass are top priorities.
