Filter by:Studies across various sports and physical activities have consistently shown that females incur more injuries compared to their male counterparts, but the underlying reasons for this disparity remain poorly understood. While differences in hormone levels between males and females have been speculated to play a role, very little rigorous research has been conducted to directly examine potential connections between sex hormones and injury risk. Specifically, females have been shown to be at greater risk for hand and wrist injuries. The higher injury incidence begins at puberty and persists across the lifespan, suggesting a link to hormonal factors. However, significant gaps remain in understanding the relationships between the menstrual cycle, exogenous hormones from birth control, and risk factors for sports-related injury in females. The purpose of this study is to examine changes in muscle strength and neuromuscular activation among females using monophasic oral contraceptives, females not using oral contraceptives, and males during one week of wrist/hand immobilization.
This study will investigate the effect of menstrual cycle (MC) and oral contraceptive pill phase on aspects of exercise physiology and athletic performance in female athletes. Specifically, this study intends to investigate the effects of circulating fluctuations in oestradiol and progesterone, experienced during the menstrual cycle and oral contraceptive pill use, on aspects of exercise physiology and athletic performance in female athletes. This research will help researchers determine if a particular hormonal profile affects physiological functioning such as muscle strength, maximum oxygen uptake and athletic performance in female athletes.
The aim of this study is to investigate whether there is a correlation between anti-Müllerian hormone during long-term use of combined oral contraceptives and the recovery time before recovered menstrual cycle after discontinuation of oral contraceptives.
The primary purpose of this study is to determine whether the treatment with AZD1981 will affect the metabolism of hormones included in oral contraceptives.
