BACKGROUND: The aim of our research was to analyze integrative reactivity, resistance and tolerance of the track and field athlete’s body in response to special loads on the middle altitude.
METHODS: Thirty runners of high and highest rank (men: N.=15, women: N.=15) and nine elite athletes (all men), aged 18-23, were recruited as participants. The analysis was performed using the licensed diagnostic equipment: automated urine chemistry analyzer; Schiller Cardiovit HT 104 PC Ergospiro system (Switzerland) for diagnosis of the cardiovascular system and individual aerobic/anaerobic threshold; LMA-10 laser microspectroanalyzer for biological specimen analysis; PGS-2 spectrograph; non-invasive system analyzer AMP; Kentavr analyzer (Microlux, Russia) for the circulatory system assessment and spectral analysis.
RESULTS: The borders of organ blood flow within the first microcycle of re-acclimatization were measured as well as absolute values of basic enzymes and amino acids influencing sport performance; the main parameters of protein metabolism and hepatic metabolism along with estimation of enzyme activity were determined under the conditions of re-acclimatization; changes in biochemical indicators in the runners during the period of the middle-altitude training camp (TC) were assessed; changes in the levels of main enzymes, hormones, and micro- and macroelements were estimated.
CONCLUSIONS: Changes in the TC conditions result in redistribution of generalized reactions of interchangeability of the functional stability and metabolic state, mutual substitution of regulating function systems, and oscillatory changes in the specific and functional system in the integrative activity of in the middle-distance runners and steeplechasers.
