Short vs Long Duration Isometrics for Patellar Tendinopathy Pain (ptinquest.libsyn.com)

• Short-duration (3s) isometrics equally effective as long-duration (45s) for pain reduction.
• Time under tension constant between conditions.
• Pain measured during single-leg decline squat.
• No difference in quadriceps strength.
• Supports use of shorter isometrics for patient adherence.

"A study examined immediate and short-term effects of short-duration (3 sec) vs long-duration (45 sec) isometric contractions in patellar tendinopathy. Both reduced pain equally, suggesting short isometrics may be sufficient for pain relief."
