Animal studies suggest that bone remodeling is under β-adrenergic control via the sympathetic nervous system. The purpose of this study was to examine the preventive effect of different doses of… Expand
Severe bone alterations under beta2 agonist treatments: bone mass, microarchitecture and strength analyses in female rats.
AIMS Beta2 adrenergic agonists are widely used in therapeutics and as doping agents by athletes. However, their effects on bone tissue, especially bone microarchitecture, remain poorly understood.… Expand

Findings from animal studies have suggested that bone remodeling is under beta‐adrenergic control. However, the level of adrenergic inhibition required to achieve the most favorable effects on the… Expand
Bone geometry and strength adaptations to physical constraints inherent in different sports: comparison between elite female soccer players and swimmers
Sports training characterized by impacts or weight-bearing activity is well known to induce osteogenic effects on the skeleton. Less is known about the potential effects on bone strength and… Expand
Preserved Bone Health in Adolescent Elite Rhythmic Gymnasts despite Hypoleptinemia
Background/ Aims: Leptin is linked to hormonal disturbances occurring in anorexia and positively linked with bone mineral density. The aim of this study was to determine whether hypoleptinemia… Expand
