Effect of Eccentric Exercises of Calf Muscles Versus Heel Insole Lift on Pain, Range of Motion, and Function in Football Players With Achilles Tendinopathy
In Brief
A clinical study evaluating Eccentric Calf Muscle Exercises and Heel Insole Lift for Achilles Tendinopathy (AT). Completed, enrolled 24 participants across 1 site.
Detailed Summary
Achilles tendinopathy is a common overuse injury in football players and is associated with pain, stiffness, and reduced functional performance. Conservative treatment options such as eccentric calf muscle exercises and heel insole lifts are frequently used in rehabilitation; however, evidence comparing their effectiveness remains limited. This randomized controlled trial compared the effects of eccentric calf muscle exercises and heel insole lifts on pain, ankle range of motion, and functional outcomes in male football players with Achilles tendinopathy. Participants were randomly assigned to one of two intervention groups. One group performed a structured eccentric calf muscle exercise program, while the other group used heel insole lifts during daily activities. Outcomes related to pain intensity, functional ability, calf muscle performance, and ankle range of motion were assessed at baseline and after completion of a 12-week intervention period. The results of this study aim to support evidence-based rehabilitation strategies for the management of Achilles tendinopathy in football players.
Study Details
Timeline
Interventions
Eccentric calf muscle exercises were performed according to Alfredson's protocol. Participants completed three sets of fifteen repetitions, twice daily, seven days per week for 12 weeks. Exercises were performed on a step with the knee extended and flexed to target the gastrocnemius and soleus muscles. Resistance was progressively increased as pain decreased.
Participants were provided with prefabricated heel insole lifts (approximately 12 mm) based on shoe size and instructed to wear them continuously in their regular footwear during daily activities for a 12-week period.
