Brief Summary

Preventive and rehabilitation programs include plyometric exercises to promote agility, power, and muscle activation pattern during jumping. These exercises also are known to cause a high mechanical load that increases the risk of a musculoskeletal injury. The knowledge regarding the musculoskeletal damage result from this configuration of exercise can help to elaborate safer and effective training and rehabilitation programs. In this study, the investigators will conduct a clinical trial to determine the acute effect of plyometric exercises on damage caused on different portions of quadriceps and biceps femoral's muscles and tendons of quadriceps, and biceps femoral, and its effects on mechanical properties.

Adult; Lower extermity; Plyometric exercise; Muscle properties

Outcome Measures

Primary Outcomes (3)

• Change from baseline of echo intensity of quadriceps and biceps femoral muscles

  Muscle echo intensity will be assessed for transversal and longitudinal ultrasonography images.

  Baseline, immediately after exercise and up to 48 hours exercise

• Change from baseline stiffness of patellar tendon

  Patellar tendon stiffness during 5 seconds rampa contraction protocol. Patellar tendon stiffness will be estimate from force/deformation relationship of tendon.

  Baseline, immediately after exercise and up to 48 hours exercise

• Change from baseline young modulus of patellar tendon

  Patellar tendon young modulus during rampa contraction protocol. Young modulus will be estimate from force/deformation relationship of tendon normalized to transverse section area of tendon.

  Baseline, immediately after exercise and up to 48 hours exercise

Secondary Outcomes (1)

• Change from baseline echo intensity of quadriceps and biceps femoral tendons

  Baseline, immediately after exercise and up to 48 hours exercise

Other Outcomes (1)

• Change from baseline muscle soreness of quadriceps and biceps femoral muscles

  Baseline and up to 48 hours exercise
