Immediate and Short-Term Effects of Short- and Long-Duration Isometric Contractions in Patellar Tendinopathy
This study examined the immediate and short-term (4 weeks) effects of long- and short-duration isometric contraction on patellar tendon pain, and tendon adaptation.
Design:
Repeated measures within groups.
Setting:
Clinical primary care.
Patients:
Participants (n = 16, males) with patellar tendinopathy.
Intervention:
Short-duration (24 sets of 10 seconds) or long-duration (6 sets of 40 seconds) isometric knee extension loading (85% maximal voluntary contraction), for 4 weeks.
Main Outcome Measure:
Immediate change in pain with single-leg decline squat (SLDS) and hop, as well as change in pain and tendon adaptation [within-session anterior–posterior (AP) strain] were assessed over 4 weeks.
Results:
Pain was significantly reduced after isometric loading on both SLDS (P
