Effects of Jumping on Growing Bones
A Phase 2 study testing Exercise intervention in people with Osteoporosis, run by Oregon State University at 1 site in United States.
Trial summary
In this study we will investigate the effects of a high-impact exercise program involving jumping on bone mass (the amount of bone) of the hip and backbone in the growing skeleton. We will also look at the effects of gradually stopping the jumping program on bone mass in the growing skeleton. Read more about this study

About this study
Official title: The Effects of Jumping on Growing Bones
In this study we will investigate the effects of a high-impact exercise program involving jumping on bone mass (the amount of bone) of the hip and backbone in the growing skeleton. We will also look at the effects of gradually stopping the jumping program on bone mass in the growing skeleton. A high-impact exercise program may build more bone during childhood, while the skeleton is still growing. This may help prevent broken bones due to loss of bone mass later in life.
We will recruit 200 children aged 5-10 to participate in the study. For 6 months we will train the children in either a jumping or stretching program. We will then gradually reduce the amount of exercise over 6 months. We will measure bone mass in the hip and backbone at the start of the study, after jumping, and 6 months after the jumping program is stopped. We will compare the results in the jumping and stretching groups.
Read the detailed description
Osteoporotic fractures are increasing at an alarming rate in this country and result in over 13 billion dollars in health costs annually. Peak bone mass, that is, an individual's maximum bone mass at the completion of skeletal acquisition, is an important determinant of fracture risk. Thus, maximizing peak bone mass may provide an effective strategy for preventing osteopenia and osteoporosis.
Various investigators have postulated that increasing bone mass by 3-5 percent would reduce fracture risk by 20-30 percent. Our data in collegiate female gymnasts demonstrate hip and spine bone mineral density values of up to 40 percent above values in normal age-matched controls and elite runners, despite menstrual irregularities. Further, we have observed the dynamic response of bone to high-impact forces in gymnasts over the training season as bone increases of 2-5 percent.
This is a randomized, controlled exercise intervention designed to evaluate the effect of high-impact loading as a means to increase bone mass during development. It will determine bone mass accrual and bone geometry at the lumbar spine and proximal femur in prepubescent girls and boys. Further, this study will evaluate the bone response from withdrawal of the stimulus over 6 months.
We will recruit 200 pre-pubescent children during two separate years and randomly assign them to a jumping or a stretching group. The jumping group will perform double leg jumps and the stretching group will act as a control. Outcome variables include bone mineral density (BMD) at the spine and hip, estimated bone volumetric density at the spine, and cross-sectional geometry of the femoral neck and diaphysis.
Implementing a specific bone-loading program during childhood will potentially allow the bone to increase both its mass and mineralization at an earlier age and therefore provide a larger foundation of mineralization for further growth throughout adolescence until skeletal maturity is reached. We expect our findings to provide a basis for the design of strategies to build bone during growth and thereby reduce osteoporotic fractures.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Exercise intervention in people with Osteoporosis, run by Oregon State University at 1 site in United States.
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 2 inclusion and 3 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 9 Jun 2016. 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 United States. 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.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00000405, which also lists 7 linked publications.
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 9 Jun 2016.
