Brief Summary:
Cryotherapy has a wide range of clinical applications in rehabilitation, used for activities such as controlling inflammation, pain control or management of edema after an injury or surgery. In the field of cryotherapy they studied cold neuromuscular responses, where it has shown a decrease in nerve conduction velocity, which leads to a decrease in muscle strength. However it has been described in some work applications brief cold ("Quick Icing") may be opposite to those described effects, increasing the strength, the time of intervention the most important and decisive in these possible improvements or decreases factor. This effect is observed in response to a few seconds of application of cold, and would be given by an increased activity of motor neurons. Assess the influence of rapid cooling application ("Technique Quick Icing") and prolonged cooling in handgrip strength when performing a manual dynamometer test in college students.

Official Title: Effectiveness of the Technique of "Quick Icing" (QI) on the Isometric Handgrip Strength Compared With the Use of Prolonged Cold and a Control: Assessment Through Dynamometry
Actual Study Start Date : April 30, 2019
Estimated Primary Completion Date : November 12, 2019
Estimated Study Completion Date : March 20, 2020

Arm Intervention/treatment
Experimental: Brief Cooling (Quick Icing)
Group receiving the application of cold on the ventral side of the dominant forearm for 30 seconds, using the technique of ice beakers dynamically.
Procedure: Brief Cooling
Brief Application of cold, for a period of up to 30 seconds on a body surface which seeks to promote the activation of the nervous system to produce increased excitability.
Other Name: Quick Icing

Active Comparator: Prolonged Cold
Group receiving the intervention of "ice bag" for a period of 5 and a half minutes from 1 minute, on the ventral side of the dominant forearm
Procedure: Prolonged Cold
Prolonged application of cold, for at least 5 minutes or more, on a body surface that aims to reduce nervous system activation by reducing the NCV.

Sham Comparator: Control
Group receives a placebo application through an "ice bag" empty. The bag will be applied from 1 minute to 6 and a half minutes, as the group of prolonged cold
Procedure: Sham Ice Bag
Placebo application through an "ice bag" empty.

Primary Outcome Measures :
  1. Comparing maximum grip strength pre and post application of cold. [ Time Frame: Baseline and 2 hours later (1 session of treatment) ]
    Force in kilograms evaluated through manual dynamometry test the time for a grip.
