Bone strength compromised by oral contraceptives
July 12th, 2001
We have all heard that weight-bearing exercise helps build stronger bones. A new study published in Medicine & Science in Sports & Exercise (2001;33:873-880) confirms this but also reveals that oral contraceptives may hinder this benefit. The study monitored bone density in young women aged 18 to 31 who engaged in regular resistance exercise and weight training over a period of two years. Bone strength increased in all but those who were taking oral contraceptives.
