“…As intermittent products we registered concentration of diene conjugates (DC) (Gavrilov, Mikorudnaia, 1983;Li, & Gleeson, 2005;Le Panse, Vibarel-Rebot, et al, 2010). As final product we registered concentration of malonic dialdehyde (MA) (Fedorova, Korshunova, et al, 2014;Papacosta, Nassis, et al, 2015;Edwards, & Casto, 2015). AOS was assessed by activity of catalase (Chevari, Shtringer, 1991;Mohammad, Azarbayjani, et al, 2010), concentration of SH-groups (Torchinskij, 1971;Walsh, 1999;Taylor, Turner, et al, 2015) and reduced glutathione (Severin, Solov'eva, 1989;Crewther, Hamilton, et al, 2015).…”

Analysis of arm wrestlers' biochemical characteristics permits to assess potential of adaptation reactions. Saliva is the most eligible object for testing. It can give indicators of pro-oxidant -anti-oxidant balance, energy metabolism and endocrine homeostasis. The purpose of the research: is studying of changes in arm wrestlers' saliva biochemical indicators under influence of competition and training loads. Material and methods: in the research sportsmen (age -22.13±3. years) participated. The sportsmen were divided into two groups; 13 sportsmen in each. Group 1 was tested in dynamic of competition loads. Group 2 was tested in dynamic of trainings loads. We used methodic for determination concentration of lipids per-oxidation (LP), antioxidant system's (AOS) condition, levels of lactic acid, pyruvic acid, рН, cortisol and thyroxine. Results: in dynamic of competitions we found correspondence of competition loads to functional potentials for elite sportsmen. In sportsmen of lower qualification we found tension of LP -AOS system, sharp increase of lactic acid, Ph shift to acid side. The offered by us indices permitted to confirm stable adaptive status of elite sportsmen. Analysis of correlation matrixes confirmed feasibility of loads and the fact that for their overcoming own adaptation reserves were quite sufficient. Changes under influence of training loads were the more expressive: we registered activation of LP -AOS, compensator increase of AOS activity, glycolysis intensification and activation of pituitary -hypophysial adrenocortical system. Conclusions: we have confirmed adequacy of bio-chemical methodic application for arm wrestlers. Bio chemical criteria illustrate different degree of stability and adaptation potentials' capacity depending on sportsmanship. We also have confirmed information significance of indices, which reflect correlation of different biochemical indicators and dynamic of different correlation structures.

“…Specifically, lower basal cortisol levels predicted increased testosterone reactivity to the stressor. Additionally, Edwards and Casto (2015) extended these results by reporting a similar negative relation between basal cortisol and testosterone reactivity during athletic competitions. These findings are parallel to those of Mehta and Josephs (2006) and Maestripieri and colleagues (2010), that also show moderate negative associations between basal cortisol and testosterone changes in response to laboratory competitions and psychosocial stressors.…”

“…Based on these results, an elegant conclusion is that the association between basal cortisol and testosterone reactivity during competitions or stressors corresponds to psychological states and behaviors in stressful and competitive contexts (Bedgood et al, 2014;Edwards and Casto;. In particular, Bedgood et at al.…”

Multiple studies show a negative correlation between basal cortisol and testosterone changes in the presence of competition and social-evaluative stressors. These negative associations are proposed to be derived from psychological responses to competition and social-evaluative stress. However, we argue that the association between basal cortisol and testosterone change may instead be a statistical consequence of positively associated variables. In this paper, we present a mathematical rationale for this alternative explanation and examples from two studies that are consistent with this alternative explanation. Both studies show that the associations between basal cortisol and testosterone change have covariance patterns consistent with this alternative possibility. We conclude that the often-found positive association between basal cortisol and basal testosterone opens the door for alternative explanations of the basal cortisol-testosterone change association rooted in the patterns of associations between hormones measured over time. We also suggest future research directions and methods for testing alternative explanations.

“…Low levels of Cortisol showed increases in testosterone than women with higher levels of Cortisol. Thus, moderating effect of Cortisol on testosterone reactivity is not limited to laboratory settings intended to increase social stress, but is also seen in the context of athletic competition (6). Same pattern of hormonal responses to victory and defeat in men and women were obtained; that defeat leads to rises in Cortisol as well as to drops in testosterone (34).…”

Stress is inevitable in competitive sports. Table tennis in the world known as a fastest ball game that requires attention and control stress. The main purpose of this study was investigation of physiological stress responses in elite table tennis players during competition. 16 female table tennis players (age average of 18.7 ± 3.8, height average of 161.6 ± 3.4 cm and weight average of 50.1 ± 4.2 kg) that participating in elective national team selected. During 8 competitive racing, salivary levels of Cortisol (C), testosterone (T) and Immunoglobulin A (sIgA) at rest, 60 and 30 minutes before and 60 and 30 minutes after racing were measured through saliva by enzymatic methods (ELISA). Data were analyzed using two-way repeated-measures analysis of variance. The findings presented that Cortisol level in loser player was significantly increased than winner player (p<0.05); while there was no significant difference in testosterone and sIgA levels (p>0.05). Also significant difference in salivary testosterone, Cortisol and sIgA periods of 60 and 30 minutes before and after competition observed in the group of winners and losers than rest(p<0.05). Table tennis competition puts high stress on young players, that probably these indicators affect the performance table tennis players. Cortisol as an indicator of stress has an important effect on losers than winners.
