Age
18 Years to 40 Years

Inclusion criteria

Inclusion criteria: Recreational athletes; male; aged eighteen to forty years; self reported localized pain in the patellar tendon; lasting three months or more; and greater than or equal to three on the ten point visual analogue scale during the single leg squat test on an inclined plane

Exclusion criteria

Exclusion criteria: Self report of uncontrolled chronic pathology; symptoms related to other knee dysfunctions; use of corticosteroid based medication; and unavailability to participate

Design outcomes

Primary

MeasureTime frame
To assess symptom severity and disability in individuals with patellar tendinopathy using the Visa-P questionnaire. Measurements are determined at baseline, during and post-intervention

Secondary

MeasureTime frame
The visual analogue scale will be used to assess pain in the patellar tendon. Measurements are determined at baseline, during and post-intervention;A 15-point Likert scale will be used to compare the feeling of change in health condition pre and post-treatment intervention. Measurements are determined at baseline, during and post-intervention;The single-leg vertical jump with countermovement will be used to evaluate jumping capacity and compare it between limbs. Measurements are determined at baseline, during and post-intervention;The neuromuscular performance of isometric and isokinetic torque will occur through the isokinetic dynamometer. Measurements are determined at baseline, during and post-intervention;To determine the success of blinding, the blinding index will be used in the 6 weeks after the start of the intervention;The individualized load will be obtained through the test of 7 to 10 maximum repetitions with the maximum possible overload in the respective repetitions in the squat exercise
