摘要：The subject of research of this paper is the study of the influence of sports experience length on reaction of cardiovascular system observed through pulse frequency in state of resting, in exercise and in recovery at sportsmen. The goal of the research of this paper is to establish the importance of differences of the observed variables between two groups of tested persons. The first group of tested persons included 30 swimmers aged 11-12 years, with sports experience length 1-3 years, and the second group included 15 water-polo players aged 16-17 years, with sports experience length 4-11 years. For the requirements of this research, the sample of variables included the following ones: age, sports experience length, height in cm, corporal mass in kg, and the speed of swimming on 43 meters. The functional variable which was monitored is the pulse frequency: 1. in state of resting, 2. immediately after the exercise, 3. in the first minute after the end of exercise, 4. in the second minute after the end of exercise, 5. in the firth minute after the end of exercise. For all the variables that are the subject of this research, the basic descriptive statistical parameters were calculated: arithmetic mean value, standard deviation, coefficient of variation, minimal and maximal value. The statistical importance of differences of arithmetic mean values of the examined variables was determined by student's T- test. The coefficient of correlation in the whole applied system of variables will also be calculated. The results that we got show that the pulse frequency in state of resting is, on average, lower at sportsmen (water-polo players) who, on average, have longer sports experience (4 years) in comparison to the sportsmen (swimmers) with shorter sports experience (2 years). Body height and mass, at water-polo players, have the effect on higher pulsation after the exercise and also, on slower recovery, which is especially manifested in the second minute of recovery.
