简要总结
The goal of this clinical trial is to find out whether multicomponent training works to treat osteoporosis in women. It will also find out about the safety of multicomponent training in this specific population. The main questions it aims to answer are:
Does multicomponent training improve bone mineral density in women?
What are the benefits of multicomponent training?
The researchers will compare the intervention group (MTC) with a control group that did not perform any type of intervention, to see if MTC training works in treating bone mineral density in women.
The participants will:
Perform MTC training for 6 months with a frequency of 3 times a week in sessions of 40-60 minutes. While the control group will carry out their daily activities normally and will only attend on the days of the assessments.
详细描述
The Strong Bones Project is a randomized controlled trial (RCT) investigating the effects of Multicomponent Training (MCT) on bone mineral density (BMD), quality of life, and risk of osteoporosis in women.
The study adopts a hybrid approach combining cross-sectional observational analyses and randomized experimental interventions. Participants will be randomly allocated to an intervention group and a control group, allowing comparison of the impacts of MCT.
The interventions include a structured physical exercise program, with three distinct approaches:
- In-Person Supervised Multicomponent Training (MCT In-Person)
- Control Group (No active intervention, only clinical monitoring)
Training sessions will include aerobic, resistance, balance, and flexibility exercises, following the American College of Sports Medicine (ACSM) guidelines for osteoporosis prevention.

入选标准
- •Age range: Women over 65 years of age. Clinical diagnosis:
- •Previous diagnosis of osteoporosis confirmed by DXA (T-score between -1.0 and -2.5 for osteopenia and ≤ -2.5 for osteoporosis).
- •Ability to exercise: Medical clearance to participate in the exercise program. and ability to perform moderate-impact physical activities and muscular endurance.
- •Level of physical activity: Sedentary women or women with low to moderate levels of physical activity, without regular practice of specific exercises for bone health in the last 6 months.
- •Agreement to the study: Signing of the Free and Informed Consent Form (FICF) and availability to participate in the training program for 6 months.
排除标准
- •Advanced clinical diagnosis: T-score below -3.0 (severe osteoporosis with high risk of fractures); History of severe osteoporotic fracture in the last 6 months.
- •Associated diseases or conditions: Uncontrolled metabolic or endocrine diseases that affect bone metabolism (e.g., hyperparathyroidism, Cushing's syndrome, decompensated diabetes); Active chronic inflammatory diseases (e.g., advanced rheumatoid arthritis, systemic lupus erythematosus); Severe chronic renal failure (stages 4 or 5).
- •Use of specific medications in the last 12 months: Bisphosphonates, denosumab, teriparatide or strontium ranelate; High-dose glucocorticoids (>5 mg/day for more than 3 months); Recent hormone therapy for osteoporosis.
- •Orthopedic or neuromuscular conditions: Severe functional limitation that prevents the performance of physical exercises (e.g., severe osteoarthritis, advanced joint instability, neurological sequelae of stroke); Orthopedic surgery in the last 6 months or indication for elective surgery for the spine or lower limbs.
- •Factors that limit adherence to the study: Difficulty in moving that prevents participation in in-person training (for the in-person MCT group); Lack of availability to attend sessions or follow the study protocol; History of low adherence to previous health-related interventions.
- •Participation in another clinical study: Women enrolled in clinical trials that may interfere with the results of the study or adherence to the protocol.

结局指标
主要结局
Bone mineral density (BMD)
时间窗: From enrollment to the end of treatment at 6 months
Bone mineral density (BMD), measured in g/cm², assesses regions such as the lumbar spine, proximal femur, and total body. It is used to diagnose and monitor osteopenia and osteoporosis based on WHO criteria. The T-score, expressed in standard deviations (SD), compares the patient's BMD to that of a young, healthy population, classifying osteopenia (T-score -1.0 to -2.5 SD) and osteoporosis (T-score ≤ -2.5 SD). The Z-score compares BMD to age- and sex-matched averages, aiding in identifying secondary causes of osteoporosis. Dual-energy X-ray absorptiometry (DXA) is the standard method for measuring BMD. Additionally, DXA provides body composition analysis, offering data on bone mass (grams), lean mass (grams/kilograms), and body fat percentage (%). These parameters enable a comprehensive assessment of musculoskeletal health and nutritional status.
