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.

Outcome Measures
Primary Outcomes (1)
Composite Measure with Ultrasound in Tendons and Muscles
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
Change from Baseline in tendon structure, an expected average of 3 days of running
Secondary Outcomes (1)
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
Study Arms (2)
Eccentric
ACTIVE COMPARATOR6 Weeks Training with eccentric Overload (Squat with Yoyo Technology) 3 Consecutive Days Running 1 hour at 80% of Maximus Heart Rate
Control
ACTIVE COMPARATOR3 Consecutive Days Running 1 hour at 80% of Maximus Heart Rate
Interventions
Training with Eccentric Overload (Squat in Yoyo Technology) during 6 Weeks 3 Consecutive Days Running at 80% Maximus Heart Rate
