Bone mineral density in response to increased energy intake in exercising women with oligomenorrhea/amenorrhea: the REFUEL randomized controlled trial

Mary Jane De Souza et al.

Summary: Energy deficiency can lead to menstrual disturbances and compromised bone health in women. Increasing energy intake can improve menstrual function, but has limited impact on bone mineral density.

Associations of Fat Mass and Fat Distribution With Bone Mineral Density in Non-Obese Postmenopausal Chinese Women Over 60 Years Old

Jingzheng Fan et al.

Summary: This study investigated the relationship between body fat accumulation, fat distribution, and bone mineral density in non-obese postmenopausal women. The results showed a positive association between total fat mass and bone mineral density, while fat distribution had a negative correlation with bone mineral density.

Enhanced Bone Size, Microarchitecture, and Strength in Female Runners with a History of Playing Multidirectional Sports

Stuart J. J. Warden et al.

Summary: The study showed that female collegiate-level cross-country runners who participated in multidirectional sports when younger had stronger bones and reduced risk of bone stress injuries.

Bone metabolic marker concentrations across the menstrual cycle and phases of combined oral contraceptive use

Dan Martin et al.

Summary: This study found that bone marker concentrations do not significantly fluctuate across the menstrual cycle, while markers of bone resorption are significantly affected by the phase of COC use. However, markers of bone formation do not significantly vary by COC phase. This suggests that phase of COC use should be considered in clinical practice and research when assessing markers of bone metabolism.

Methodological Approach of the Iron and Muscular Damage: Female Metabolism and Menstrual Cycle during Exercise Project (IronFEMME Study)

Ana B. Peinado et al.

Summary: The IronFEMME Study aims to investigate the influence of sex hormones on iron metabolism and muscle damage in female athletes, including those with regular menstrual cycles, oral contraceptive users, and postmenopausal women. This observational controlled randomized counterbalanced study involves different exercise protocols and menstrual cycle phases for evaluation.

The Potential Mechanism of Exercise Combined with Natural Extracts to Prevent and Treat Postmenopausal Osteoporosis

Tongxi Zhou et al.

Summary: This study reviews the anti-PMOP effects and mechanisms of exercise and natural extracts, aiming to explore the possibility of combining the two for anti-PMOP, providing a new perspective for joint intervention research and a new direction for the treatment strategy of PMOP.

Physical Activity, Menstrual History, and Bone Microarchitecture in Female Athletes with Multiple Bone Stress Injuries

Sara E. Rudolph et al.

Summary: The study found that female athletes with a history of multiple bone stress injuries spent more time in physical activities during high school, engaged in more uniaxial loading activities, and had a higher proportion of cases with amenorrhea. This suggests that engaging in sports with multiaxial loading and maintaining normal menstrual status can reduce the risk of multiple bone stress injuries.

Methodological Considerations for Studies in Sport and Exercise Science with Women as Participants: A Working Guide for Standards of Practice for Research on Women

Kirsty J. Elliott-Sale et al.

Summary: Until recently, there has been a lack of demand and interest in female-specific sport and exercise science data, resulting in most data being derived from studies with male participants. A shortage of specialist knowledge on female physiology in the sport science community, coupled with a reluctance to adapt experimental designs for female-specific considerations, has hindered progress in this field. Furthermore, a lack of agreement on terminology and methodological approaches has impeded researchers' ability to develop evidenced-based guidelines for female exercisers.

Bone health and hormonal contraception

Morena L. Rocca et al.

Summary: Short-term and long-term steroid contraceptive systems may have negative effects on bone health in adolescent girls, but seem to have minimal impact on bone health in perimenopausal women. Depot medroxyprogesterone acetate (DMPA) may lead to bone loss with prolonged use, while other progestin-based contraceptives do not have detrimental effects on bone health. Further randomized studies are needed for confirmation.
