A quick turn during a handball game might do more for your bones than a long walk. New research suggests that the type and intensity of exercise are more important for bone health than how much you do.
This study, published in Sports Medicine—Open, found that activities with explosive movements, quick changes in direction, and turning led to the strongest signals for new bone growth. These findings could help create better exercise plans to keep bones strong and prevent osteoporosis.
Rethinking Bone-Building Workouts
Researchers looked at 24 studies with 1,238 healthy adults. Instead of waiting for bone density to change, they checked blood markers that show if the body is making new bone. These markers can show a response in just weeks. This is much faster than traditional bone density tests.

The study found that high-intensity sports with repeated bursts of movement and sudden turns showed the best results. Recreational football and handball increased bone formation markers by 45% to 46%. In contrast, walking, step aerobics, and regular gym resistance training had weaker effects.
It's important not to start intense exercise suddenly, especially for those with health conditions like heart problems, muscle or joint issues, or osteoporosis. Always talk to a doctor before starting a new activity or increasing intensity.
Viktória Barna, the study's first author, noted a surprising finding. Resistance training, often recommended for bone health, didn't significantly affect bone metabolism markers. Low to moderate endurance exercises like walking also showed no major long-term effect.
This doesn't mean lower-intensity activities aren't healthy. However, the research suggests bones need a stronger push to stay strong over time.
The Importance of Intensity
Dr. Nóra Sydó, a co-author, summarized the findings. She said that while regular physical activity has many benefits, low-intensity exercise alone might not be enough for bone metabolism. High-intensity exercise could trigger early positive changes in bone formation. This might help slow bone loss and support healthy aging.
The researchers believe these results can help create exercise programs based on evidence. These programs would focus on keeping bones healthy and preventing osteoporosis.
