Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
