An interventional study of Flexibility training in Spine Injury, Hamstring Injury and Lumbar Hyperlordosis, sponsored by Universidad Católica San Antonio de Murcia. Completed at 1 site in Spain. Open to female participants, including healthy volunteers. Per ClinicalTrials.gov, last updated 2024-06-06.

The goal of this clinical trial is to analyse the effect of an intervention program based on hamstring flexibility on the extensibility and curvatures of the spine in dancers.
Participants will be dance student with ten years of experience that will undergo a program of stretching four times per week during seven weeks, followed by a detraining period, and a retraining period of three weeks. There will be a pre-test, a post-test and two re-tests after the intervention.
The results will be compared with a control group of dancers that will not take part in the stretching program.
Four measurements were carried out, one before the intervention (pre-test), one after the first stretching programme (post-test), one after a short period of detraining (re-test 1) and the last one at the end of a second period of intervention (re-test 2), analysing the intra-group and inter-group differences for each of the dependent variables.
The sample components (n=61) were divided into two groups following a random distribution carried out by an external researcher. The intervention group (IG), which consisted of 31 dancers, underwent the hamstring stretching programme for a first period of 7 weeks and a second period of 3 weeks after a short period of detraining. The intervention consisted of static and dynamic stretching of the hamstring muscles 4 days per week. The control group (CG), composed of 30 dancers, did not perform the stretching programme. Both groups attended their practical classes in the conservatory. During the detraining period the dancers of both groups took a break from physical exercise.
The variables measured are hamstring extensibility and sagittal spine disposition and pelvic tilt.

Counted across the registry records on this site, refreshed daily.
The inclusion criteria were:
(c) not suffer from any chronic pathology or at the time of the study; (d) not practising any other physical exercise apart from dance.
Exclusion criteria:
The intervention group will undergo a flexibility training focused on hamstring extensibility. Each will they will take part in four stretching sessions besides the normal dance training.
Other: Flexibility training
The control group will continue with their training routine during the experiment.
Each session consisted of three or four exercises, of which three were static stretches and if there was a fourth, it was dynamic. The duration of each exercise was 20 seconds with 15 seconds rest between sets and 30 seconds rest between exercises.
