We prospectively studied the effect of heavy-load eccentric calf muscle training in 15 recreational athletes (12 men and 3 women; mean age, 44.3 7.0 years) who had the diagnosis of chronic Achilles tendinosis (degenerative changes) with a long duration of symptoms despite conventional nonsurgical treatment. [...] Key Method Calf muscle strength and the amount of pain during activity (recorded on a visual analog scale) were measured before onset of training and after 12 weeks of eccentric training. At week 0…Expand

Bone Mass in the Calcaneus after Heavy Loaded Eccentric Calf-Muscle Training in Recreational Athletes with Chronic Achilles Tendinosis
TLDR
Heavy-loaded eccentric calf-muscle training resulted in a fast recovery in all patients, equaled the side- to-side differences in muscle strength, and was not associated with side-to- side differences in BMD of the calcaneus. Expand
Eccentric calf muscle training compared with therapeutic ultrasound for chronic Achilles tendon pain--a pilot study.
TLDR
Both interventions proved acceptable to the patients with no adverse effects and the potential effectiveness compared with therapeutic ultrasound in subjects with relatively sedentary lifestyles in an NHS hospital setting is investigated. Expand
Eccentric calf muscle training in non-athletic patients with Achilles tendinopathy.
TLDR
Eccentric exercises, though effective in nearly 60% of patients, may not benefit sedentary patients to the same extent reported in athletes. Expand
Plantar Flexor Muscle Architecture Changes as a Result of Eccentric Exercise in Patients With Achilles Tendinosis
TLDR
A 6-week eccentric training protocol increased the GM muscle fascicle length by 12%, and this correlated with improvement in a validated patient outcome scoring system, and further study is warranted to determine a predictive relationship between improvement of GM fascicles length and outcome scores. Expand
Effects of Eccentric Muscle Training on Achilles Tendon Adaptation of Healthy Persons
TLDR
Eccentric training induces change in the tendon which is supported by an increase in its mechanical properties, which may reduce and prevent the risk of tendon injury in young people and athletes. Expand
The effect of eccentric and concentric calf muscle training on Achilles tendon stiffness
TLDR
Six weeks of eccentric training can alter Achilles tendon stiffness while a matched concentric programme shows no similar effects. Expand
Superior short-term results with eccentric calf muscle training compared to concentric training in a randomized prospective multicenter study on patients with chronic Achilles tendinosis
TLDR
The good clinical results previously demonstrated in the pilot study with eccentric calf muscle training on patients with chronic Achilles tendinosis were reproduced in this multicenter study, showing superior results to treatment with concentric training. Expand
Eccentric training in patients with chronic Achilles tendinosis: normalised tendon structure and decreased thickness at follow up
TLDR
Ulasonographic follow up of patients with mid-portion painful chronic Achilles tendinosis treated with eccentric calf muscle training showed a localised decrease in tendon thickness and a normalised tendon structure in most patients. Expand
Chronic Achilles tendon pain treated with eccentric calf-muscle training
TLDR
The conclusion is that treatment with eccentric calf-muscle training produced good clinical results in patients with chronic painful mid-portion Achilles tendinosis, but not in Patients with chronic insertional Achilles tendon pain. Expand

Achilles Tendinosis and Calf Muscle Strength
TLDR
It seems that the recovery in concentric and eccentric calf muscle strength after surgery for Achilles tendinosis is slow, with no obvious advantages in recovery of muscle strength with a short immobilization time versus a longer period used in a previous study. Expand
Chronic Achilles Tendinitis and Calf Muscle Strength
TLDR
It is demonstrated that 6 months of postoperative rehabilitation for chronic Achilles tendinitis is not enough to recover concentric and eccentric plantar flexion muscle strength compared with the non injured side. Expand
Functional postoperative treatment of Achilles tendon repair
TLDR
Early controlled motion can safely and effectively be used following Achilles tendon repair in the motivated, reliable patient, as shown by this study. Expand
Early Motion After Repair of Achilles Tendon Ruptures*
TLDR
Early range of motion after Achilles repair is safe and there is no increased risk of rerupture in compliant patients and the patients achieved good return of plantarflexion strength, power, and endurance. Expand
Calf muscle atrophy and muscle function after non-operative vs operative treatment of achilles tendon ruptures.
TLDR
It is recommended that all athletes with achilles tendon ruptures be treated surgically and in non-athletes and older patients non-operative treatment might be considered. Expand
Immediate Free Ankle Motion After Surgical Repair of Acute Achilles Tendon Ruptures
TLDR
Early free ankle motion after repair of Achilles tendon ruptures proved safe with very satisfactory clinical re sults, which justified a randomized, prospective study comparing it with traditional ankle immobilization. Expand
Achilles Tendon Lesions in Sport
TLDR
The specific factors of the various conditions demonstrated as causes of Achilles tendon pain are set out and the value of different laboratory and other investigations indicated in the particular pathological conditions are indicated. Expand
Alterations in the in vivo torque-velocity relationship after Achilles tendon rupture. Further evidence of speed-specific impairment.
TLDR
These findings demonstrate that both groups exhibited speed-specific impairment with the loss of muscle strength being greatest at slow speeds and the degree of impairment was dependent on the ankle position at which torque was measured. Expand
Achilles tendon injuries in athletes.
TLDR
The typical histological features of chronically inflamed paratendineal tissue of the Achilles tendon are profound proliferation of loose, immature connective tissue and marked obliterative and degenerative alterations in the blood vessels which may have an important role in the pathophysiology of these injuries. Expand
Surgical treatment of chronic Achilles tendinitis
TLDR
Between 1977 and 1985, 170 patients suffering from chronic Achilles tendinitis were treated surgically, with the high percentage of operated cases for this group of 980 patients explained by the fact that these 980 patients were a selected group of patients not including mild cases or patients with a tran sient Achilles tend initis.
