About

The purpose of this study is to compare the acute effect of the use of different thermal modalities associated to the training of passive flexibility of the hamstring muscles in the amplitude of motion of the knee extension.

Full description

Context: In the literature there is a disagreement of results and protocols regarding the use of thermal modalities associated with the training of flexibility of the hamstring muscles. Most studies on the subject, used the heat and cryotherapy prior to stretching these. Therefore, the investigators aimed to conduct an experimental study using the therapeutics term concomitant arrangements to passive static stretching these muscles.

Methods: Clinical trial randomized crossover, which will a sample of 42 subjects (healthy young men, aged 20 to 30 years). Were divided into 3 groups (Group 1 passive static stretching hamstrings, Group 2 heat + passive static stretching hamstrings and Group 3 cryotherapy + static stretching hamstrings passive) with 14 subjects each. Where the participants will control themselves, since all carry out the three interventions, only at different times. Each action will be performed every 7 days. Individuals will be subjected to active test of the range of motion of knee extension (goniometer) and hamstring muscle strength (dynamometer).

Enrollment: 34 patients

Sex: Male

Ages: 20 to 30 years old

Volunteers: Accepts Healthy Volunteers

34 participants in 3 patient groups

Stretching associated with shortwave heating

Active Comparator group

Description:

Applying deep heat through the shortwave equipment for 20 minutes, in coplanar application to the posterior part of the thigh associated with flexibility training of the hamstrings in the last 10 minutes of the session, performed by passive static stretching of the hamstring muscles in 10 repetitions of 30 seconds, with a 10 second pause between each repetition.

Treatment:

Procedure: Flexibility training with or without different thermal modalities

Stretching associated with cryotherapy

Active Comparator group

Description:

Cryotherapy application for 20 minutes, applied to the posterior part of the thigh associated with flexibility training of the hamstring muscles in the last 10 minutes of the session, performed by passive static stretching of the hamstring muscles, in 10 repetitions of 30 seconds , with a 10 second pause between each repetition.

Treatment:

Procedure: Flexibility training with or without different thermal modalities

Stretching isolated

Other group

Description:

The flexibility training of the hamstring muscles will be by passive static stretching of the hamstring muscles in 10 repetitions of 30-second , with a 10-second pause between each repetition.

Treatment:

Procedure: Flexibility training with or without different thermal modalities
