Patellar Abnormality Clinical Trial
Official title:
Efficacy of Load Control in Eccentric Exercises in the Increase of the Cross-sectional Area and Pain Threshold of the Patellar Tendon, and of the Strength of the Quadriceps in Volleyball Players. A Randomized Clinical Trial
Introduction. Vertical jump is the main movement in volleyball, and the main etiological
factor of patellar tendinopathy. The eccentric exercise has been proved as the most effective
intervention in improving this factor.
Aim. Annalise the effectiveness of the load control during the eccentric exercise to increase
the cross-sectional area as well as the increase of the pain threshold of the patellar
tendon, and the gain of the quadriceps maximum strength, in volleyball older players.
Study design. Randomized clinical study, simple blind, multicentric and with a follow-up
period.
Methods. 40 volleyball players will be recruited, who will be randomized to the two groups:
experimental (control of the load based on the RM during the eccentric exercise of
quadriceps) and control (without load control). There will be an intervention of 4 weeks with
2 weekly seasons of 10 minutes each. The dependent variables will be: cross-sectional area
(ultrasound evaluation), pain threshold in the patellar tendon (analog or digital algometer)
and the maximum strength of the quadriceps (linear encoder or estimating the RM). In case of
normality of the distribution of the sample, parametric tests will be used: student t-test of
related samples (difference between evaluations in each rump) and repeated measures ANOVA
(intra- and intergroup effect).
Expected results. To observe an increase in the cross-sectional area, pain-threshold of
patellar tendon and quadriceps maximum strength.
