Long-Hold Yielding Isometric Exercise for Patellar Tendinopathy in Weightlifting Athletes (clinicaltrials.gov)

• Long-hold yielding isometrics (30-60s) targeting patellar tendon
• Outcomes: tendon stiffness, vascularity, pain, function
• RCT comparing isometrics to eccentric loading

"A clinical trial protocol evaluates long-hold yielding isometric exercises (30-60 seconds) to modulate tendon stiffness and vascularity in symptomatic patellar tendinopathy. The intervention aims for pain reduction and functional improvement."
