Smoking Of Tobacco And Physiological Functional Skills

Smoking of tobacco is a medical and social problem. This habit favours increases of the death rates from illnesses of the cardiovascular system, respiratory and other systems. Stopping of smoking causes abstinence symptoms, which in turn are greater obstacles to others than to the smoker himself. The purpose of this study was the research of differences between non-smokers' group and smokers' group, to verify the influences that smoking causes in some physiological functional skills. The research method of two groups was used: non-smokers' group (77 entities) and smokers' group (73 entities). The submaximal effort was conducted by Astrand's Test. Before, during and after the test, the frequency of heartbeats (Pulsi), blood saturation with oxygen (SatO2), absolute and relative maximal oxygen uptake (VO2max.abs. & rel.) were measured. Whereas the basic statistical parameters show systematic differences between the two groups in all values, the T-test proved significant differences (p<0.01) between the two above-mentioned groups in the frequency of heartbeats while resting (HR. 0'), and in saturation of blood with oxygen in the period of rest, in the 5th minute of the test and in 1st and 2nd minute of recovery (SatO20', 5', 1'R, and 2'R). Through Canonical Discriminant Analysis significant differences were proved in the measured values.
