Brief Summary

Balance is essential for successful dance performance. The effort of salsa dancers is given by the levels of stability, produced by the muscular activation of lower limbs.

The objective of the study is to assess the effectiveness of an intervention of plyometric exercises in the improvement of balance in salsa dancers from 18 to 25 years.

Randomized clinical study. 40 dancers will be randomized to the two study groups: experimental (application of plyometric exercise protocol) and control (without intervention). The treatment will last 5 weeks, with 2 weekly sessions of 25 minutes each. The dependent variables will be: equilibrium (measured with star excursion balance). The sample distribution will be calculated using the Kolmogorov-Smirnof test. The changes after each evaluation will be calculated with the t-student test. With an ANOVA of repeated measures, the intra and intersubject effect will be observed. The effect size will be obtained with Cohen's formula.

It is expected to see improvement in the stability of the ankle and the level of balance in the dancers.

Conditions

Balance; Distorted

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: PREVENTION
• Blinding Strategy: SINGLE

Study Groups

Experimental group

Athletes included in the experimental group will perform a plyometric exercise protocol. Each session will consist of a 4-station circuit with 1 minute rest between each station and 30 seconds between sets

Group Type: EXPERIMENTAL

Plyometric protocol

Intervention Type: OTHER

Each session will last 20 minutes, with 2 sessions a week, over a period of 5 weeks. The intervention will last 20 minutes, which consists of a 4-station circuit.

Exercise 1: jump on the rope, with your feet together at a moderate pace. Exercise 2: In standing with hands on the hip and hip flexion (one foot in front). Knee flexion and dorsal ankle flexion, with straight trunk. Alternate legs.

Exercise 3: box jump (jump on the box with both feet at the same time). Exercise 4: depth jumps from box to antoher box (jump on the box with both feet at the same time and when falling, immediately jump to the other box).

1 minute with 30 seconds between sets.

Control group

Athletes included in the control group will follow their usual warm-up routine.

Group Type: NO_INTERVENTION

No interventions assigned to this group
