Experimental: cryotherapy by immersion
Cryotherapy group immersion (GI) composed of 20 volunteers, which will be subjected to immersion cryotherapy upper limb dominant in cold water (6°C ± 2°C), at the level of the elbow joint.
Other: cryotherapy by immersion
Experimental: Control group
(CG) consisted of 20 volunteers, which will be submitted to immersion of the dominant upper limb in water at room temperature indifferent to the level of the elbow joint;
Other: Control group
- Evaluate the strength and muscle synergism after cryotherapy immersion [ Time Frame: 2 years ]The objective of this study is to Evaluate the strength and muscle synergism between wrist flexors and extensors after forearm immersion cryotherapy. Testing grip strength will be carried out 3 times in a row, with 4 seconds of maximum voluntary isometric contraction, with a 1 minute interval between them; before, immediately after, 25 minutes and 50 minutes after immersion. Strength evaluation is conducted using a load cell. Concurrent with this test, the signal will be collected electromyographic extensor and flexor wrist, upper and middle trapezius fibers and anterior serratus.
- Blood flow velocity before and after immersion of the forearm cryotherapy [ Time Frame: 2 years ]The data of blood flow velocity will be collected through the portable Doppler ultrasound wave continues. Immediately before the strength tests will be collected the data from the radial artery blood flow (3 times per collection), so there are no changes due to muscular work required in the handgrip test.
- Changes in skin temperature before and after cryotherapy by immersion of the forearm [ Time Frame: 2 years ]The skin temperature data will be acquired by a digital infrared thermographer. Immediately before the strength tests will be collected temperature data cutaneous (3 times per collection), so there are no changes due to muscular work required in testing grip.
