Effectiveness of High-Intensity Versus Low-to-Moderate-Intensity Resistance Training in Improving Muscle Strength and Bone Mineral Density in Older Adults: A Systematic Review and Meta-Analysis

Studied: 1,283 participants across 18 RCTs, adults ≥50

Comparing 18 trials in adults 50+, high-intensity training (≥70% of one-rep max) beat lighter loads for building leg strength, while both intensities protected bone density about equally — with no difference in fall or injury rates.

Progressive Resistance Training for Concomitant Increases in Muscle Strength and Bone Mineral Density in Older Adults: A Systematic Review and Meta-Analysis

Studied: Men and/or women ≥65 years (pooled RCTs)

Across randomized trials in adults 65 and older, progressive resistance training reliably increased leg strength and hip/femur bone density together — with higher training frequency linked to bigger gains in both.

High-Intensity Resistance and Impact Training Improves Bone Mineral Density in Postmenopausal Women With Osteopenia and Osteoporosis (the LIFTMOR trial)

Studied: Postmenopausal women with low bone mass

Postmenopausal women with low bone mass trained twice a week for eight months with heavy deadlifts, squats, overhead press and jumping chin-ups. The heavy-training group improved spine and hip bone density and function, with a very low injury rate under supervision.
