[Characteristics of lipid peroxidation and markers of endogenous intoxication in monitoring physical loads during rower training].

The objective of the present study was to estimate the informative value of characteristics of lipid peroxidation (LOP) and the level of middle molecular weight peptides (MWP) in the blood as indicators to be used for monitoring the training process in 37 rowers. Each athlete was examined in triplicate (a total of 90 observations). Coefficients of correlation between the above characteristics and the total duration of physical exercises performed during a one-month period were calculated for each of the five intensity categories. The relationship between the extent of training and the level of LOP end-products proved to be opposite to the relationship between the extent of training and the plasma MWP level. The latter parameter positively correlated with the total duration of physical exercises for most intensity categories. A similar correlation was established between pedagogical characteristics of the training process and the aldosterone to cortisol ratio.
