Objectives:
Achilles tendinopathy (AT) is the most common injury among masters runners. The single-leg horizontal hop test (SLHH) is a common return to running test utilized to assess the propulsive phase of running. The purpose of this study was to investigate the kinetic relationships between the SLHH test and running in masters runners with and without AT.
Design:
Cross-Sectional Observational Study.
Setting:
University Biomechanics Lab.
Participants:
Thirty-two master runners over age fifty were included, with 16 with AT (60.31 ± 8.37) and without AT (59.93 ± 4.95).
Main Outcome Measures:
3D motion capture and force plates were used to assess peak joint moments and powers during the SLHH and running. A simple linear regression was used to establish relationships.
Results:
Masters runners with AT demonstrated SLHH peak lower extremity joint moments that were predictive of running peak lower extremity joint moments. Healthy masters runners demonstrated SLHH peak ankle plantarflexion moments that were predictive of running peak ankle plantarflexion moments. Both groups demonstrated SLHH peak ankle plantarflexion powers that were predictive of running peak ankle plantarflexion powers.
Conclusions:
The SLHH hop test may be an appropriate tool to predict running kinetics in masters runners with AT but not healthy masters runners.

Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed...
