Objective PCOS is the most frequent female endocrine disorder, affecting 5%-10% of women, is characterized by hyperandrogenism, oligo-/anovulation, and polycystic ovaries. The aim of the present research is to evaluate the expression of steroidogenic acute regulatory protein (StAR) and CYP19 (aromatase) mRNA in the ovary of EV-induced PCOS rat model and the effect of the treadmill and running w...

BACKGROUND To date, little is known for pacing in ultra-endurance athletes competing in a non-stop event and in a multi-stage event, and especially, about pacing in a multi-stage event with different disciplines during the stages. Therefore, the aim of the present study was to examine the effect of age, sex and calendar year on triathlon performance and variation of performance by events (i.e.,...

Previous experience seems to be an important predictor for endurance and ultra-endurance performance. The present study investigated whether the number of previously completed races and/or the personal best times in shorter races is more predictive for performance in longer non-stop ultra-triathlons such as a Deca Iron ultra-triathlon. All female and male ultra-triathletes who had finished betw...

BACKGROUND The purpose of this study was to define predictor variables for recreational male Ironman triathletes, using age and basic measurements of anthropometry, training, and previous performance to establish an equation for the prediction of an Ironman race time for future recreational male Ironman triathletes. METHODS Age and anthropometry, training, and previous experience variables we...

Background: Regarding the negative effects of androgenic anabolic steroids (AASs) abuse, the long-term effect of nandrolone decanoate with/without two intensities of endurance exercise training was investigated on heart tissue and electrocardiogram (ECG) in rats. Methods: The experiment was conducted on 63 male Wistar rats, which were 4 months old. The rats were divide into groups of control (C...

Am J Physiol Endocrinol Metab 286: E208–E216, 2004. First published October 21, 2003; 10.1152/ ajpendo.00051.2003.—The purpose of this study was to elucidate the mechanisms underlying low-intensity exercise-induced peroxisome proliferator-a...

This study investigated changes in performance and sex difference in top performers for ultra-triathlon races held between 1978 and 2013 from Ironman (3.8 km swim, 180 km cycle, and 42 km run) to double deca iron ultra-triathlon distance (76 km swim, 3,600 km cycle, and 844 km run). The fastest men ever were faster than the fastest women ever for split and overall race times, with the exception...
