Adaptation in Lower Extremity After 3 Running Days, With a Group Trained by Eccentric Overload

Sports Injuries Clinical Trial

Official title: Differences in Muscle (Vastus Laterals and Gastrocnemius Medialis) and Tendon Adaptation (Patellar and Achilles) in Lower Extremity After 3 Running Days With a Group Trained by Eccentric Overload, Measured by Ultrasound and Thermography

Status Completed

Clinical Trial 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.

Clinical Trial 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. ;
