Overview
Brief Summary
This study evaluates the changes in muscles and tendons in the lower limb after an intervention of fatigue during 3 consecutive days between trained or not healthy subjects. One of the 2 groups received training by eccentric overload previously.
Detailed Description
Changes in muscle and tendon tissues, due to exercise, could determine in the future the possibility of an injury. Understand the changes in the mechanical tissues is a key tool for prevention. The evaluation of the thickness and area in tendons, the existence of new vessels within the tendon, muscle pennation angle or thermography are tools that have been widely used to detect these changes. Running is one of the activities that can cause more muscle-tendon injuries, specially overuse injuries. However, the eccentric exercise suggest to make some adaptations in different tissues that may be beneficial to prevent damage after exercise.

Outcomes
Primary Outcomes
Composite Measure with Ultrasound in Tendons and Muscles
Time Frame: Change from Baseline in tendon structure, an expected average of 3 days of running
Ultrasound in Patellar and Achilles Tendon, to measure area, thickness and new blood vessels with Doppler. Ultrasound in Vastus Lateralis and Gastrocnemius Medialis to measure pennation angle
Secondary Outcomes
- Temperature changes in Patellar and Achilles Tendon as assessed by thermography(Change from Baseline in tendon structure after 3 days of running. Just immediately and 10 minutes after intervention)
