The study involves 120 women over the age of 50.
All participants in the study take part in high-intensity strength training for 10 months.
In addition, half of the participants receive vitamin D3 at a dose of 4,000 IU/day.
The investigators hypothesize that training combined with vitamin D3 supplementation will be more effective in preventing osteoporosis than training alone.
