Athletics Kenya (AK) said on Sunday athletes selected for the 10,000 metres would be allowed to race once only.
Those selected for the 3,000 metres steeplechase and 5,000 metres can race twice while runners competing in events between 400 and 1,500 metres will have a maximum of three races.
Officials said no more racing would be allowed after the Zurich Golden League meeting on August 6.
AKA chairman Isaiah Kiplagat said "serious steps" would be taken against any manager who interfered with the training plans of the national coaches.
"It is a matter of great concern not only to us but to the entire global athletics fraternity that our performance is going down even when we have selected a strong team like this one," said Kiplagat.
"We appreciate the work managers have done for our athletes by exposing them. But when we are in training camp, I don't want to hear any manager giving individual athletes so-called professional coaching that will run contrary to our coaches' plans."
