„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? When the recreational tennis players acquire the basicskills of the game, they will in effect start playing competitively, be it singles or doubles. 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.

I doubt anyone will be surprised that sports and no alcohol are good for us. Sports and alcohol are like day and night.

Let’s look at the areas in which sports benefit us and protect us:

  • maintains our optimum weight
  • benefits the muscles, bones and protects us against osteoporosis
  • after food there are no inflammatory conditions that can lead to atherosclerosis
  • can prevent diabetes, cardiovascular diseases, locomotor system diseases and a number of tumors
  • contributes to increased mental well-being, reduces stress and anxiety
  • helps rest and quality sleep

And let’s see! They are almost exactly the same things that alcohol is destroying or expose us to a higher risk:

  • contributes to overweight, and consequently to other civilization illnesses
  • increases the risk of cardiovascular disease
  • increases the risk of digestive tract tumors
  • heats the liver and causes liver disease (cirrhosis, pancreatic inflammation)
  • it causes drowsiness and numbness, but it brings a shallow and poor sleep

Do you know what is the main factor that will prevent you from regular exercising? Alcohol. Being smoking will also do its own. Drinking alcohol takes a lot of time, among other things. As soon as a person stops drinking or significantly reduces their consumption, an unexpected space opens up to new activities that often involve sports and movement.

Alcohol and sport are not just what is bad or good for us. They are interconnected vessels – the more you put yourself into the life of one, the less space remains to the other.

Runners, fond of beer, please do not hate me. I also recall the conclusion of my fastest half-marathon, where during the last two kilometers I only had the vision of a depleted pint. But I did not drink a bottle of wine for the three months of the half-marathon training.

It always ends in one thing: what we want most in life and what we most value.
