Brief Summary:
It is known that cryotherapy has various therapeutic applications, among which are the control of the inflammatory process, resolution of edema, analgesia and decreased spasticity. In addition, the use of cold as an agent to decrease or facilitate neuromuscular activity has been documented. The scientific information that supports the relationship of short duration cold with the improvement of the motor response is scarce and outdated. The objective of this design is to evaluate the effectiveness of rapid cooling or Quick Icing technique in the improvement of muscular performance. The foregoing would be relevant in the field of Kinesiology (Physiotherapy) because it would attribute cold properties that could influence the increase in muscle strength, favoring the performance of different therapeutic exercises, training or high performance sport, in addition to supporting the proposal of this intervention in patients with particular neurological disorders.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 150 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Care Provider, Investigator)
Primary Purpose: Treatment
Official Title: Effectiveness of Quick Icing Technique on Force of Jump: Valuation Through a Jump Platform and a Mobile Application.
Estimated Study Start Date : April 21, 2023
Estimated Primary Completion Date : December 1, 2023
Estimated Study Completion Date : December 1, 2023

Arm Intervention/treatment
Active Comparator: Experimental: Quick Icing
Group receiving the application of cold on the ventral side of the thigh (bilaterally) for 30 seconds, using the technique of ice beakers dynamically.
Device: Quick icing
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: Brief cooling

Active Comparator: Experimental: Prolonged Cold
Group receiving the intervention of "ice bag" for a period of eight minutes n the ventral side of the thigh (bilaterally).
Device: 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 decreased nerve conduction velocity.

No Intervention: Control:
Group that does not receive intervention and that will rest for ten minutes.

Primary Outcome Measures :
  1. Comparing maximum jump strength changes pre and post application of cold. [ Time Frame: Baseline and 2 hours later (1 session of treatment) ]
    Force evaluated through movil aplication and jump plataform.
