How Bone Density Changes with Age — What the Evidence Says, and How In-Home Physiotherapy in Vancouver Helps

Updated: 3 days ago

Senior man receiving guided leg therapy at home with licensed physiotherapist — promoting bone density and in-home physiotherapy support in Vancouver for aging adults.

As we age, our bones are constantly remodeling—old bone is broken down and new bone is formed. After about age 30, we typically reach peak bone mass. Thereafter, bone mineral density (BMD) gradually declines.


This decline is natural, but how quickly bones lose density — and how prone we are to osteopenia, osteoporosis, or fractures — depends on a range of factors. Physiotherapy, especially resistance, weight-bearing, and impact-based exercise, can play a powerful role in slowing or reversing bone loss.


This post explores:

  • How bone density changes in men vs. women

  • What recent RCTs and meta-analyses say about bone health

  • How mobile physiotherapy in Vancouver supports bone strength at home


What Happens to Bone Density with Age: Men vs. Women

Women: After menopause (typically in the early 50s), estrogen levels drop sharply. Estrogen slows bone resorption (the breakdown of bone). Without it, bone loss accelerates. As the Mayo Clinic notes, bone loss is a natural part of aging, but for women, the drop linked to menopause is a key driver.

Men: Bone loss occurs more gradually in men. On average, they have higher peak bone mass and maintain testosterone longer, providing a protective effect. Still, after age 50–60, bone loss accelerates. According to Mayo Clinic, both sexes lose 1–3% of bone mass per year past age 50.


While everyone is affected, postmenopausal women are at a substantially higher risk.


What Recent RCTs Tell Us: Resistance, Impact, and Combined Exercise in Women

Research strongly supports exercise as a frontline intervention for maintaining and improving bone density.


Meta-Analysis on Resistance Training (2025)

A BioMed Central meta-analysis of 15 RCTs (~314 in resistance training groups, ~301 in controls) showed:

  • Moderate intensity resistance training ≥3x/week

  • Sessions lasting ≥ 40 min for ≥ 48 weeks

  • Result: Significant BMD improvements at the lumbar spine, total hip, and femoral neck


Exercise + BMD in Postmenopausal Women

A PMC study confirmed that combining resistance + weight-bearing exercise had greater positive impact on lumbar spine and hip BMD than either alone.


High-Impact Exercise in Older Adults (75+ Years)In a 6-month RCT published in Oxford Academic, women aged 75–85 doing resistance + agility + impact training had measurable gains in cortical bone density at lumbar spine and hips.


LIFTMOR Study (PubMed)While slightly older, the LIFTMOR trial remains foundational: postmenopausal women doing high-intensity resistance & impact training twice weekly gained:

  • +2.9% lumbar spine BMD

  • +0.3% femoral neck BMD compared to control groups who declined.


What Type, Frequency, and Duration of Exercise Works Best?

Based on evidence from Mayo Clinic and studies above:


Types of Exercise:

  • Resistance (weights, bands, bodyweight)

  • Weight-bearing (brisk walking, stair climbs, hopping)

  • Agility/balance (dynamic movements, single-leg holds)


Intensity:

  • Moderate to high, adjusted to the individual's ability

  • High-intensity yields greater results if supervised


Frequency:

  • 3x/week yields stronger results for lumbar spine and femoral neck BMD


Duration:

  • Most effective programs last 6 months or more

  • Longer durations produce more stable bone gains


How In-Home Physiotherapy in Vancouver Can Help

Physiotherapy delivered in the home has distinct advantages, especially for aging adults.
