Reproductive hormones and interleukin-6 in serious leisure male athletes

Lifestyles associated with different types and intensities of exercise result in improved health including positive changes in chronic low-grade inflammatory biomarkers.

description Lifestyles associated with different types and intensities of exercise result in improved health including positive changes in chronic low-grade inflammatory biomarkers. Alternatively, some forms of exercise adversely affect reproductive health of men, including changes in circulating reproductive hormones. To explore the associations between exercise intensity and circulating levels of reproductive hormones, and inflammatory analytes in serious leisure athletes (triathletes and cyclists) and recreational athletes. Male athletes 18–60 years old, 16 triathletes, 46 cyclists and 45 recreational athletes, were recruited to provide plasma for the measurement of total testosterone, estradiol, follicular stimulating hormone, luteinizing hormone (LH), sex hormone-binding globulin (SHBG), cortisol, interleukin-6 (IL-6), and interleukin-1β (IL-1β) levels, and calculation of free androgen index (FAI) and the estradiol:SHBG ratio (ESR). Plasma estradiol concentrations were more than two times higher in cyclists than in triathletes and recreational athletes ( p
