„A“and „B“ types of behavior were introduced by cardiologists Meyer Friedman and Ray H. Rosenman in the 1970s, and this issue has been alsoadopted by the psychology of health. A – type behavior is characterized by competitiveness, ambition, a strongneed to be assertive, a tendency to perform several activities at a time, a lack of time, and a sense of time preassure. Demonstration ofhostility, aggressiveness, competition, and overall hyperactivity are more significant in this typeof behavior.

Persons with B – type behaviordisplay characteristics opposite to those in theA – type.The behavior of these people is much more relaxed, content, unafraid. B types rarely wish for many things in aconstantly reduced time. These people are more focused on the environment than on themselves. Their movements are smoother, their voice is calm, leveledand unhasty.They are not troubled bysmall things, have a more even-keeled mood and devote more time to out-of-work activities. Their ambitions can be as big as those of A types, but their efforts and results of work are more likely to satisfying and delivering self-confidence. B typebehavior is steady, more calm, “healthier”.

A type behavior is considered to be a significant risk factor for coronary heart disease (CHD). It has been found that there is a significantly higher incidence of persons with such behavior in CHD patients. Due to the high enthusiasm of A-types, the persons  this tendency are also more prone to the „burn out“syndrome. This type also occurs to a greater extentamong persons with increased nervous instabilitym and in termsof profession in managers.

How to prevent CHDin A types- aerobic exercise activities, including sports and exercise! Even just12-week aerobic trainingprogram can help.


Top Manager “Mr. Man“has health problems associated with the combination of high levels of stress in his work environment and A type behavior. He visitsa doctor,who recommends that he engage in sportsto compensate for his workload. “Mr. Man “starts to practice tennis. He tells himself ” I am already doing sporttwice a week.” Here comes the cardinal questionthough, what kind of sportactivity is appropriate for him in this case. Why not tennis? This type of sport can be yet another risk factor in certain situations. What’s going on in playing tennis?

The question becomes, who will win. Thus, “Mr. Man “is once again in a competitive environment and experiences tension. Scientific evidence confirms the importance of aerobic  activities, such asswimming, cross-country skiing, running, jogging, cycling and cardio training at the fitness center, as a prevention and compensation for A type risk behavior with regard to CHD.
