Physiology of strength training as a form of prophylaxis and counteraction against civilization threats

The aim of this paper was to evaluate the scope of influence a modified circuit training of endurance and strength character, carried out in line with an original programme, on the selected physiological parameters. 30 volunteers who train in fitness clubs in Kraków on an everyday basis were selected by means of purposeful selection to participate in the research. This group was divided into two subgroups. One of them used an experimental programme of circuit training, the other took part in the same training programmes they had used so far. After six weeks the two groups were subjected to research. Heart rate and blood lactate levels were measured. Heart rate monitors were used to measure heart rate. Research results show that the proposed training programme is carried out at a high intensity level, which is indicated by the recorded heart rate and blood lactate levels. The research programme carried out with the use of the circuit training positively influences fundamental physiological parameters; average and maximal heart rate frequency were lowered, energy expenditure in the course of the training was lowered; blood lactate levels after the training were reduced as well and post-exercise restitution was increased. The proposed form of training can be an example of physical activity of significant health-oriented advantages.
