Swimming Training Repercussion on Metabolic and Structural Bone Development; Benefits of the Incorporation of Whole Body Vibration or Plyometric Training: The RENACIMIENTO Project
A study testing Whole-body vibration (Powerplate®) and Jumping intervention in people with Body Composition, run by Universidad de Zaragoza.
Trial summary
Swimming training is associated with decreased bone mass and lower bone mass acquisition during growth periods, mainly when compared to other weight-bearing sports. Little information is available in adolescents pointing in the same direction but still controversial. Read more about this study

About this study
Official title: Swimming Training Repercussion on Metabolic and Structural Bone Development; Benefits of the Incorporation of Whole Body Vibration or Plyometric Training. The RENACIMIENTO Project
Swimming training is associated with decreased bone mass and lower bone mass acquisition during growth periods, mainly when compared to other weight-bearing sports. Little information is available in adolescents pointing in the same direction but still controversial.
On the other hand, bone strength do not only depends on bone mass but on bone structure and microarchitecture. The cross sectional area, cortex thickness or trabecular density are important aspects of bone health. There are few studies on the effect of swimming on bone architecture of adolescents. This information is relevant for present and future health of adolescents practicing swimming and for all the organizations promoting this sport. Jumping and whole body vibration training programs seem to elicit important osteogenic effects; however, there is little information on this regard in adolescent population, even less in these adolescents with potentially decreased bone acquisition such as swimmers.
The main aims of this research project are therefore, to analyze the effect of swimming training on bone mass, metabolism, structure and architecture in adolescents analyzing possible relationships among them. Secondly, to test whether including short boots of jumping or whole body vibration may be able to palliate the possible deleterious effects of swimming and facilitate a normal or even healthier bone development. And finally to study the durability of training-related bone gains over time.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Whole-body vibration (Powerplate®)Device
Swimmers will perform a 15 minute whole-body vibration training 3 times per week. This intervention will be performed with a Powerplate®. The vibration protocol will be progressive starting with 30 Hz and an amplitude op 4 mm reaching at the end of the protocol 38 Hz and 4 mm amplitude.
Jumping interventionBehavioural
Swimmers will perform a jumping intervention, 15 minutes 3 times per week. Jumps will include drop jumps, one leg jumps, squat jumps and countermovement jumps.
| Study group | Role | What they receive |
|---|---|---|
| Swimmers | No intervention | Swimmers that continue their normal swimming activity |
| WBV swimmers | Experimental | Swimmers that perform a whole-body vibration training Receives: Device: Whole-body vibration (Powerplate®) |
| Plyometric swimmers | Experimental | Swimmers that perform a plyometric training Receives: Behavioral: Jumping intervention |
| Sedentary controls | No intervention | Controls that do not perform swimming or other physical activities |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in body composition during 3 years evaluated by dual energy X-ray
Measured: Change from baseline in body composition at 3 years
Secondary outcomes (1)
Change in bone strength and structure evaluated by peripheral quantitative computed tomography
Measured: Change from baseline in bone strength and structure at 3 years

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?
Change in body composition during 3 years evaluated by dual energy X-ray (time frame: Change from baseline in body composition at 3 years). 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 26 Mar 2025.
