Effectiveness of EE With Vibration Versus Cryotherapy in Rectus Abdomini Muscle Thickness and Inter-recti Distance

12 weeks, 5 days/week, once a day, 2 exercise, 3 sets/execise, 15 repetition/set of eccentric exercise of foot plantar flexors First exercise with knee in extension, second exercise with knee in flexion. Previously subjects should cold their leg in ice water during sexteen minutes at a temperature of 8ºC (+/-2ºC)

12 weeks, 5 days/week, once a day, 2 exercise, 3 sets/execise, 15 repetition/set of eccentric exercise of foot plantar flexors First exercise with knee in extension, second exercise with knee in flexion.During the exercise subjects will be subjected to vibration. Vibrations parameters: Frequency: 35Hz, Amplitude: 4 milimeters, Force: 3,9G
