About this study
Official title: Mediterranean Diet and Progressive Resistance Training Effects on BMD and Bone Turnover in Elderly
This randomized controlled trial was designed to investigate the effects of progressive resistance training (PRT) combined with a Mediterranean diet on bone mineral density (BMD) and bone turnover markers (BTMs) in older adults.
Participants underwent a detailed medical history assessment, clinical examination, and dietary evaluation. Individuals who met the inclusion criteria provided written informed consent prior to participation. All procedures were conducted in accordance with the Declaration of Helsinki, and the study protocol was approved by the Ethics Committee of Manouba University (no. C.S. ISSEP.KS N˚040/2024).
Eligible participants were randomly allocated to either the experimental group (EXP; n = 22) or the control group (CON; n = 19). The intervention lasted 12 months. During this period, the EXP group participated in supervised PRT sessions combined with a Mediterranean diet intervention, while the CON group received no structured intervention.

Detailed Description
This randomized controlled trial was conducted to examine the effects of progressive resistance training (PRT) combined with a Mediterranean diet on bone mineral density (BMD) and bone turnover markers (BTMs) in older adults.
Participants were recruited and screened through a detailed medical history assessment, clinical examination, and dietary evaluation. Eligible individuals who met the inclusion criteria provided written informed consent before participation.
Participants were randomly assigned to either the experimental group (EXP; n = 22) or the control group (CON; n = 19). The intervention lasted 12 months. During this period, the experimental group participated in supervised progressive resistance training sessions combined with a Mediterranean diet intervention, while the control group received no structured intervention and maintained their usual lifestyle.
Bone mineral density and bone turnover markers were assessed at baseline and after the 12-month intervention period.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Mediterranean Diet combined with Resistance TrainingBehavioural
Also called Mediterranean Diet and Supervised Resistance Training
Participants followed a Mediterranean diet and engaged in a supervised progressive resistance training program performed three times per week for 12 months. The training was progressively adapted based on individual capacity, focusing on major muscle groups using standard resistance exercises.
| Study group | Role | What they receive |
|---|---|---|
| Mediterranean Diet + Progressive Resistance Training | Experimental | Participants followed a Mediterranean diet combined with a supervised progressive resistance training program performed three times per week for 12 months. Receives: Behavioral: Mediterranean Diet combined with Resistance Training |
| Control Group | No intervention | No Structured Intervention |
What is being measured
The primary outcome is the main question the study is designed to answer.
Bone Mineral Density (BMD)
Bone mineral density (BMD) was assessed using dual-energy X-ray absorptiometry (DXA) at the lumbar spine and femoral neck. Measurements were performed at baseline and after the 12-month intervention period. esults will be reported as BMD values expressed in g/cm².
Measured: Baseline and 12 months
Secondary outcomes (3)
Bone Formation Markers
Bone formation marker, osteocalcin were assessed in fasting blood samples. Unit of Measure: ng/mL
Measured: Baseline and 12 months
Bone Formation Markers
Bone-specific alkaline phosphatase (BAP) were assessed in fasting blood samples. Unit of Measure: U/L
Measured: Baseline and 12 months
Bone Formation Markers
Fasting serum P1NP concentrations will be assessed as a marker of bone formation. were assessed in fasting blood samples. Unit of Measure: ng/mL
Measured: Baseline and 12 months

Questions about this trial
What is this clinical trial studying?
A study testing Mediterranean Diet combined with Resistance Training in people with Bone Health and Osteoporosis, run by University of Sfax at 1 site in Italy.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 28 May 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Bone Mineral Density (BMD) (time frame: Baseline and 12 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 May 2026; AzTrials last refreshed its copy on 6 Nov 2026.
