Brief Summary

Intensity is a "qualitative" variable of a muscle stretching protocol, which is very little studied due to its inherent characteristic of the individual being stretched. However, it was pointed out as an important factor for ADM gain. To verify the effects of different intensities of static passive stretching on flexibility, neuromuscular and functional performance in soccer athletes.

Outcome Measures

Primary Outcomes (1)

  • Range of motion (ROM)

    The measurement will be performed in two positions: with hip flexed at 90 ° and with extended leg elevation, using goniometry for measurement.

    48 h after intervention

Secondary Outcomes (5)

  • Pleasure after stretching program

    1 minute after intervention

  • Pain after stretching session

    1 minute after intervention

  • Functional performance

    48 h after intervention

  • Electromyographic responses of the hamstring

    48 h after intervention

  • Passive torque

    48 h after intervention

Study Arms (4)

Control Group

NO INTERVENTION

The subjects of the CG will receive the same orientations of the other groups in relation to the importance of the routines of stretching activities, but during the study period, they will not be able to perform stretches during their day to day life.

Experimental Group 1

EXPERIMENTAL

The experimental group 1 will have the sensation of "SENSATION SENSING WITHOUT DESCONFORT" as an intensity for the application of the passive stretch protocol.

Other: Passive static stretch

Experimental Group 2

EXPERIMENTAL

The GE2 will have the feeling of "MAXIMUM DISORDER WITHOUT PAIN" as the as an intensity for the application of the passive stretch protocol.

Other: Passive static stretch

Experimental Group 3

EXPERIMENTAL

GE3 will have the sensation of "MAXIMUM TOLERABLE PAIN" as the as an intensity for the application of the passive stretch protocol.

Other: Passive static stretch

Interventions

Passive static stretchOTHER

Each experimental group will be submitted to 10 (ten) sessions, with three (3) weekly sessions of static passive stretching, with a 48 h interval between them. Each session will be performed 3 (three) maneuvers containing a duration of 30 seconds, this being the same rest time, performed in all experimental groups.

Masking Details
The randomization process of the sample will be carried out through the electronic website http://www.randomization.com, carried out by a subject external to the experimental and evaluation procedures. With this data, the site will generate a specific coding for each group and will randomly distribute the subjects into four groups: Control Group (GC), Experiment Group 1 (GE1), Experiment Group (GE2) and Experiment Group 3 (GE3). The distribution will be kept in an opaque and sealed envelope, being revealed only to P2 only at the time of intervention. The P1, who will carry out the measurements, will not know to which group the individual belongs. To maintain the "blinding" procedure of the study, each individual at the time of intervention will spend 10 minutes in the intervention room (being 4 minutes for preparation and 6 minutes for intervention) and each group will have a corresponding color for the convenience of P2 White, blue, green and yellow).
