Testosterone induces skeletal muscle hypertrophy by multiple mechanisms, including its
effects in modulating the commitment of pluripotent mesenchymal cells. These changes in …

The aim of this review is to highlight two emerging concepts for the elite athlete using the
resistance-training model:(i) the short-term effects of testosterone (T) and cortisol (C) on the …

Objectives: This study investigated the effect of a 12-week long-acting testosterone
administration on maximal exercise capacity, ventilatory efficiency, muscle strength, insulin …

The question whether the muscle hypertrophy induced by resistance training, hormone
administration or genetic manipulation is accompanied by a proportional increase in muscle …

Phytoecdysteroids are structural analogs of the insect molting hormone ecdysone. Plants
comprise rich sources of ecdysteroids in high concentration and with broad structural …

Objectives: The primary objective of this study was to assess the effect of a 6-month
testosterone supplementation therapy on functional capacity and insulin resistance in …

20-Hydroxyecdysone (20E) is an ecdysteroid hormone that regulates moulting in insects.
Interestingly, 20E is also found most abundantly in plant species and has anabolic effects in …

The purpose of this study was to examine the acute effect of resistance exercise (RE) on
muscle androgen receptor (AR) and glucocorticoid receptor (GR) protein content. Fifteen …

Androgens promote anabolism in the musculoskeletal system while generally repressing
adiposity, leading to lean body composition. Circulating androgens decline with age …

The effect of gender and caloric restriction on mitochondrial content and oxidative-
phosphorylative capacities has been investigated in rat gastrocnemius muscle. Muscle …
