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).
Time frame: 4 minutes before the intervention, 5 minutes after the intervention and 30 minutes later
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).
Time frame: 4 minutes before the intervention, 5 minutes after the intervention and 30 minutes later
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).
Time frame: 4 minutes before the intervention, 5 minutes after the intervention and 30 minutes later
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).
Time frame: 4 minutes before the intervention, 5 minutes after the intervention and 30 minutes later
Maximal displacement change
Maximal displacement of the muscle after being excited with an electric impulse, using an electromyography test (miliseconds).
Time frame: 4 minutes before the intervention, 5 minutes after the intervention and 30 minutes later
Stiffness change
Resistance to an external force that deforms its initial shape, using a "Myoton" (Newtons/metre).
Time frame: 2 minutes before the intervention, 7 minutes after the intervention and 30 minutes later

Elasticity change
Capacity to recover its initial shape after the removal of the external force that lead to its deformation, using a "Myoton" (logarithmic decrement of a tissue's natural oscillation).
Time frame: 2 minutes before the intervention, 7 minutes after the intervention and 30 minutes later
Relaxation change
Time for a muscle to recover its shape from deformation after the removal of an external force, using a "Myoton" (miliseconds).
Time frame: 2 minutes before the intervention, 7 minutes after the intervention and 30 minutes later
Gastrocnemious strength change
Isometric strength of the gastrocnemious muscles using a handheld dynamometer "microFET 2" (newtons).
Time frame: 8 minutes before the intervention, 1 minute after the intervention and 30 minutes later
