Energy

Like any other attribute, no one knows exactly how it affects players. One thing is certain, the higher the better. Energy is lowered by training and matches. It is raised by rest. If it falls below 60, players are at a greatly increased risk for long term injury. If you are fortunate enough to get a national team player, the manager will not play them if you don't keep their energy up.

Training and Energy The harder you train your players the lower their energy will be. The key is to find the maximum level of training you can do while keeping energy at a reasonable level. I recommend keeping your starters at at least 90 energy. You can let the subs go a little lower. There are two approaches to adjusting training to rest players.

Option 1 Adjusting match day and off day intensity. Use 100% of skills training in your schedules. Start your match day intensity (for that day's starters) at 50% and your off day (everyone else) at 100%. Adjust downward until their energies are at good levels.

Option 2 Leave your intensities as they are. Create multiple versions of your training schedules. Make one with skills training at 100% and the others with lesser percents. Unused percentage points go to rest. If energy is low, use a schedule with high rest. If it is high, use one with less rest.

Never set your players to idle. This button is useless. They will not train and they will not rest.

Effects of Games There's no set effect a game will have on energy, except it will make it go down. Factors included number of lines, shift lengths, and intensity.

Regeneration Build up your stadium's regeneration facility to increase rest rates. The higher you get this, the more you can train your players and the faster your team will improve.
