What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Delay time change | Time between an electric impulse and 10% of the contraction of the muscle that is being excited with an electric impulse, using an electromyography test (miliseconds). | 2 minutes before the intervention, and 8 minutes after the intervention | 
| Contraction time change | Time between 10% and 90% of the contraction of the muscle that is being excited with an electric impulse, using an electromyography test (miliseconds). | 2 minutes before the intervention, and 8 minutes after the intervention | 
| Sustain time change | time between 50% of the contraction and 50% of the relaxation of the muscle after being impulsed with an electric impulse, using an electromyography test (miliseconds). | 2 minutes before the intervention, and 8 minutes after the intervention | 
| Relaxation time change | time between 90% and 50% of the relaxation of the muscle after being impulsed with an electric impulse, using an electromyography test (miliseconds). | 2 minutes before the intervention, and 8 minutes after the intervention | 
| Maximal displacement change | Maximal displacement of the muscle after being excited with an electric impulse, using an electromyography test (miliseconds). | 2 minutes before the intervention, and 8 minutes after the intervention | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Gastrocnemious strength change | Isometric strength of the gastrocnemious muscles using a handheld dynamometer microFET 2 (newtons). | 8 minutes before the intervention, and 2 minutes after the intervention | 
| Passive ankle dorsiflexion change | Passive range of motion of the ankle dorsiflexion, using an inclinometer (degrees). | 6 minutes before the intervention, and 4 minutes after the intervention | 
| Jump height change | Maximum jump height with one leg using the application My Jump 2 (centimeters). | 10 minutes before the intervention, and 1 minute after the intervention | 
| Stiffness change | Resistance to an external force that deforms its initial shape, using a Myoton. | 5 minute before the intervention, and 5 minute after the intervention | 
| Elasticity change | Capacity to recover its initial shape after the removal of the external force that lead to its deformation, using a Myoton. | 5 minute before the intervention, and 5 minute after the intervention | 
| Relaxation change | Time for a muscle to recover its shape from deformation after the removal of an external force, using a Myoton (miliseconds). | 5 minute before the intervention, and 5 minute after the intervention |
