Oestrogen has anabolic and bone-protective effects. Its decline at menopause accelerates the loss of both muscle mass and bone mineral density. Women in the decade following menopause are at higher risk of sarcopenia, osteoporosis, cardiovascular disease, metabolic syndrome, and increased abdominal fat deposition than at any earlier point in their lives. Resistance training is the most powerful lifestyle intervention available to counter all of these effects simultaneously.
Bone Density: The Non-Negotiable Priority
Bone density peaks in the late 20s and declines progressively thereafter, with the most rapid decline occurring in the five years following menopause when oestrogen withdrawal is most acute. Fractures, particularly of the spine, hip, and wrist, are among the most serious consequences of osteoporosis and are associated with significant morbidity and mortality in women over 70. Progressive resistance training, particularly when it includes high-impact loading, is the most evidence-based lifestyle intervention for maintaining bone mineral density.
Muscle Mass: The Metabolic and Functional Priority
Women lose approximately one to two percent of muscle mass per year after 50, with this rate accelerating in the absence of resistance training. The functional consequences include reduced strength, altered gait, increased fall risk, reduced metabolic rate, and progressive loss of independence. Research consistently shows that women who engage in progressive resistance training two to three times per week maintain significantly greater lean mass and functional capacity than those who do not.
What the Training Should Include
- Progressive resistance training two to three days per week targeting all major muscle groups
- Weight-bearing activities such as brisk walking, stair climbing, or impact exercises for bone density
- Balance training to reduce fall risk, increasingly important after 60
- Adequate protein intake of at least 1.6 grams per kilogram daily to support muscle protein synthesis
- Vitamin D and calcium adequacy to support bone metabolism and muscle function
