Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Objectives: To evaluate the effectiveness of plyometric exercises in the increase of quadriceps muscle strength, volume and stability dynamic in female athletic of water polo players from 18 to 25 years old.
Study Design: A randomized, multicentric, single-blind clinical study with a follow-up period.
Methodology: 25 water polo players will be recruited and randomly assigned to the two study groups: experimental (plyometric exercises plus isometric exercises with elastic bands) and control (isometric exercises with elastic bands). The intervention will last for 8 weeks, with 3 weekly sessions, of 15 minutes each. The study variables will be: strength (measured with the RM test), muscle volume (using anthropometry), and dynamic stability (through the SEBT test). The analysis of normality will be carried out with the Shapiro Wilk test. In case of homogeneity of the groups, we will use parametric tests: t-student test of repeated measures (difference between evaluations) and ANOVA of repeated means (intra and intersubject effect).
Expected Results: It is expected to observe improvement in muscle strength and quadriceps volume, as well as dynamic stability.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Plyometric exercises
The subjects included in the experimental group will carry out an intervention using plyometric exercises and isometric exercises with elastic band for the quadriceps muscle. Each session will last 15 minutes, taking place for 3 days a week, in a period of 8 weeks. The intervention will be made at the beginning of the training session.
Experimental
The Drom Jump technique with the legs flexed will be performed with the patient standing in front of a bench 30 cm high by 100 cm wide. The physiotherapist will be placed lateral to the athlete. The subject will be asked to jump up from the box or bench, with the hip and knees in semi-reflexion, with his hands on his hip and he will be asked for an explosive jump, followed by a jump downwards falling the floor of the same way.
The technique of lateral jumps on cones will be carried out by means of unipodal jumps, achieving a distance of 50 cm between cones. The physiotherapist will stand in front of the athlete. The subject will be asked to perform a lateral unipodal explosive jump by flexing the hip and knee.
Isometric exercises
The subjects included in the experimental group will carry out an intervention of isometric exercises with elastic bands for the quadriceps muscle. Each session will last 8 minutes, taking place for 3 days a week, in a period of 8 weeks. The intervention will be made at the beginning of the training session.
Control
Elastic bands will be combined with isometric exercises in 3 sets of 10 repetitions each. The exercises they will perform are front squat. On the one hand, separating the legs at the height of the shoulders with hip and knee flexion, with the elastic band above the knees, maintaining the position 20 seconds.
In the following exercise, with the elastic band on the ankle, in unipodal support at the same time that the contralateral limb is free of support, the hip will be flexed at 45º with full knee extension, requesting the athlete to keep the tension 20 seconds, performing 3 sets of 10 repetitions.
