Effects of Eccentric Strength Training’s Time on Daily Plasma Testosterone Levels among Tunisian Sedentary Athletes

Effects of Eccentric Strength Training’s Duration on Daily Plasma Testosterone Levels in Tunisian Male Sedentary Athletes

“…In fact, with only one training per day either in the morning or in the evening, daily concentrations of this hormone increase in athletes. This increase is the result of a reduction in plasma volume with hemoconcentration and increased blood viscosity on the one hand, and a rise in testicular perfusion on the other hand as it was reported by Souissi et al (2013). However, by imposing two training sessions daily to athletes, successively in the morning and in the evening, which probably led to depletion, a decrease in daily production of this androgen was observed.…”

“…Training plan recommended in this study was reported by Souissi et al (2013). The selected athletes for our study have concentric and eccentric strength training respectively during 4 and 8 weeks.…”

“…Recent studies reported that the eccentric strength training's time, mainly in the afternoon, greatly influences the production of testosterone in athletes (Sedliak et al, 2007;Yildirim and Derksen, 2012; Souissi et al, 2013). However, it did not specify the effects of the duration on the synthesis of this hormone.…”

“…It is secreted mainly by the testes and plays an important role in growth, development and maturation of the male skeletal system. It also contributes to skeletal muscle growth and to the development of strength (Bhasin et al, 2001, Crewther et al, 2012Souissi et al, 2013). At rest and during physical exercise, hormonal system intervenes in the metabolism of carbohydrates, fats and proteins.…”

Effects of Monological and Sophrological Trainings on the Development of Attention and Retention in Tunisian Male Kick Boxers

“…Sports, individual or collective, is a set of physical activities that improve the health and the well being of humans (Aquatias et al, 1999). These can sometimes be part of sports competitions and so involving a variety of athletic training methods to further improve the technical, physical etc.. and this to excel and be better (Souissi et al, 2013). However, it has always proved that even if they are developed and better on the above points, a lack of concentration could often be the cause of the failure of athletes (Feltz and Landers, 1983).…”
