The aim of this study was to investigate the effect of eccentric
strengthening on pain, muscle strength, endurance, and functional fitness factors
in Achilles tendinopathy patients. DESIGN: Thirty-two male patients with Achilles
tendinopathy were assigned to either the experimental group that performed
eccentric strengthening or the control group that performed concentric
strengthening (n = 16, both groups) for 8 wks (50 mins per day, three times per
week). A visual analog scale, an isokinetic muscle testing equipment, the
side-step test, and the Sargent jump test were used to assess pain, muscle
strength, endurance, and functional fitness factors before and after the
intervention. RESULTS: In comparison with the control group, the experimental
group showed significant improvement in pain, ankle dorsiflexion endurance, total
balance index, and agility after the intervention (P < 0.05). However, there was
no significant difference in dexterity between the two groups. CONCLUSIONS:
Eccentric strengthening was more effective than concentric strengthening in
reducing pain and improving function in patients with Achilles tendinopathy;
therefore, regular eccentric strengthening is important for patients in a clinical setting.
