Description
Inclusion Criteria:
- Physically active population (physical activity between 1 and 3 weekly sessions). With the final purpose to adjust the results to normality and refer to a general population.
- Subjects who have received the information sheet and have given their consent informed to participate in the study.
Exclusion Criteria:
- People who reproduce pain or symptomatology to the execution of the exercise of the treatment.
- People who have had symptoms in the last 2 months in the region below patellar
- Present musculoskeletal injuries or inability to perform the protocol experimental.
- Individuals with a training frequency equal to or greater than 5 sessions per week or that present a RM equal to or greater than 110kg. Since they do not fit a population and may affect the homogeneity of the sample.

Experimental: BFR group
Training is applied to this group using low-load exercises with restriction of blood flow.
|
Training is applied to this group using low-load exercises with restriction of blood flow. Based on the variables used by the major part of the protocols used in studies on the ERFS, the protocol that will be applied to this group will consist of the following parameters.
A pressure equivalent to 80% of the minimum pressure necessary for the total occlusion of the femoral artery. • Cuff placement: proximal quadriceps. |
Active Comparator: High load group
A program will be applied to this group of exercise with high loads as a method of treatment

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
To evaluate structural changes in the tendon through the use of ultrasound
Time Frame: Baseline
|
Ultrasound will be used in order to collect the data of the images of each participants.
Then, we will asses and compare possible changes in thickness, measured in cm, of each tendon before, after and 24 hour after the intervention.
|
Baseline
|
To assest the echogenicity of each tendon by using software Fiji-Image J
Time Frame: Baseline
|
A delimited area of 159x20 pixels inside the tendon structure will be selected.
Then the program may classified all the pixels of each area on a gray scale of 255, resulting in an histogram of each tendon before, after and 24 hour after the intervention, measured in pixels in the gray scale.

Baseline

Other Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Evaluate the possible presence of micro vascularization of the patellar tendon through the visualization of the tendon structure with the doppler system of the ultrasound.
Time Frame: Baseline
|
The Doppler mode of ultrasound will be used to observe and compare the presence of micro-vascularization inside the patellar tendon structure, before, immediately after and 24 hours after performing the intervention for each subject.
The images where the doppler mode could detect some micro-vascularization may be assigned with ''Yes´´ and those which does not show any evidence of micro-vascularization ,may be assigned as ''no´´.
