Effects of Jumping on Growing Bones Clinical Trials References presented on Clinical Trials Search isn't meant to be a substitute for proven healthcare advice, trips or professional assistance using a genuine physician. We are not docs. Always confer with your physician about Effects of Jumping on Growing Bones conditions. Clinical Trials Search.org is a site devoted to listing clinical research studies in human subjects. Effects of Jumping on Growing Bones Clinical research trials and Effects of Jumping on Growing Bones healthcare trials happen in hundreds of localities throughout the United States of America. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials usually evaluate the potency of new drugs. The propose of the studies / projects is to answer particular human health questions. Clinical trials are a popular way for mDs, government agencies, and private sector companies to detect cures for all sorts of conditions, such as Effects of Jumping on Growing Bones. Effects of Jumping on Growing Bones Clinical Trials and other clinical trials allow volunteers to acquire healthcare treatment choices before they are available to the general public. Some times the subjects recieve professional assistance for free, and every now and again they are compensated for their time. Sometimes there is a cost for a Effects of Jumping on Growing Bones clinical trial. Subjects frequently obtain the most expert healthcare possible for their Effects of Jumping on Growing Bones condition. Risks are a reality, nevertheless, and can include more or frequent doctor trips, medical risks (possibly life-threatening), and/or the treatment being uneffective. Trials are federally governed with stern guidelines to protect clinical trials patients.

Effects of Jumping on Growing Bones
For Condition: Osteoporosis
Status: Completed
Sponsor(s): National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) ,
Synopsis: 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.
Details: 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.
