your training is set too high or you bought a player that had their training set too high.
If it is the first case, just lower your team training to very low to get your team back to health.

If it is the second train on average or low and let your low energy player come back to life.Last edited on 2009-03-18 at 0:55

Lower energy lowers players' performance.

Training on lower intensity levels will lower the amount of training your players receive that week. Roughly 3 training points (100 pops the skill) total per intensity level, so if you're training focus on passing for example, switching your energy to low will probably cost you no more than 1-2 training points on low for your passing skill per week. AKA not a huge deal.
