Background. The aim of our research was to evaluate the impact of magnetic stimulation on recovery following submaximal physical effort.  Material and methods. The study was conducted on a group of 19 students. The subjects performed submaximal effort on an ergometer. The test began with a 50-watt load, gradually increased to a maximum load of 3.5 watt/kg. Directly after exertion, the subjects rested 30 minutes in prone position. While resting, they were subjected to low-frequency magnetic fields (VIOFOR JPS device and a program using Ion Cyclotron Resonance, ICR) or to a placebo. During both the exertion and the resting period we continuously monitored the heart rate, oxygen consumption and minute ventilation of the lungs. The blood lactate concentration was assessed before every test and at 3, 5, 9, 15, and 30 minutes after exertion. Results. No significant differences were found in any of the tested variables between the group subjected to magnetic stimulation and the placebo controls. During the 30-minute rest period the rate of return of the variables to baseline values was identical in both groups. Conclusions. Magnetic stimulation of the whole body applied directly after submaximal physical effort did not significantly influence blood lactate elimination, heart rate, minute ventilation of lungs, or oxygen consumption.
