EVALUATION OF CARDIAC FUNCTIONS IN MIDDLE AGE ELITE RUNNERS

Marathon, half-marathon and long distance running are one of the sports branches that athletes

have the highest level of physical capacity. Sudden cardiovascular complications can be

observed during or after exercise, especially in individuals who perform long-distance running

exercises over a certain age. The aim of the study is to examine some hematological

parameters and cardiac damage markers of individuals (over 35 years old) at individual race

pace on the treadmill, before, after, and within the following 24 hours.

Nineteen healthy male amateur runners, aged >35 years (mean age 47.42±1.68) were enrolled.

The athletes’ maximal aerobic capacities were determined and after that athletes performed

the running exercise for one hour at the individually determined pace. Venous blood samples

were obtained before the one-hour exercise, just after the exercise, fourth hour and twentyfourth

hour after the exercise. CK, CK-MB, Troponin-I, NT-proBNP and hemogram values

were determined.

We observed a rise in the levels of cardiac biomarkers after the one-hour exercise (p<0.05).

Although there were no pathological condition in the ECG recordings, signs of dehydration

were observed following exercise.

Long distance and high pace running exercise is an exercise model, in which physiological

limits are pushed, cardiovascular stress is increased and many blood parameters are elevated.

Although there are no signs of permanent or irreversible cardiac damage in our study, it is of

great importance for elderly individuals who perform this type of exercise, should repeat their

general health examinations intermittently.
