Background: Surgery that spares the intact portion of the ACL seems to be more favorable. This surgical technique has a positive effect on joint stability, joint position sense and functional scores in patients with partial ACL lesions. Aim: This study aimed to assess isokinetic muscle strength following surgical reconstruction of partial ACL lesions. Materials and Methods: The study included 1...

The aim of the present study was to examine whether or not the compliance of the gastrocnemius medialis (GM) tendon and aponeurosis is influenced by submaximal fatiguing efforts. Fourteen elderly male subjects performed isometric maximal voluntary plantarflexion contractions (MVC) on a dynamometer before and after two fatiguing protocols. The protocols consisted of: (1) submaximal concentric is...

OBJECTIVES: To analyze the effects of motor learning on knee extension-flexion isokinetic performance in knee osteoarthritis patients. METHODS: One hundred and thirty-six middle-aged and older sedentary individuals (111 women, 64.3±9.9 years) with knee osteoarthritis (130 patients with bilateral) and who had never performed isokinetic testing underwent two bilateral knee extension-flexion (co...

The aims of this study were to examine the acute effects of static stretching on peak torque, work, the joint angle at peak torque, acceleration time, isokinetic range of motion, mechanomyographic amplitude, and electromyographic amplitude of the rectus femoris during maximal concentric isokinetic leg extensions at 1.04 and 5.23 rad x s(-1) in men and women. Ten women (mean +/- s: age 23.0 +/- ...

BACKGROUND The relationship between muscle injury and strength disorders remains a matter of controversy. PURPOSE Professional soccer players performed a preseason isokinetic testing aimed at determining whether (1) strength variables could be predictors of subsequent hamstring strain and (2) normalization of strength imbalances could reduce the incidence of hamstring injury. STUDY DESIGN C...

[Purpose] To examine changes in the knee joint's isokinetic muscle functions following systematic and gradual rehabilitation exercises lasting for 12 weeks for male and female patients who underwent anterior cruciate ligament (ACL) reconstruction. Differences in muscle functions between the uninvolved side (US) and the involved side (IS) before surgery, differences in muscle functions between U...

BACKGROUND The purpose of this study was to evaluate the peak torque of the knee flexors (H) and the quadriceps muscle (Q) at 12 and 24 weeks after isolated anterior cruciate ligament reconstruction with semitendinosus and gracilis autografts. MATERIALS AND METHODS There were 20 patients (8 females, 12 males), with the mean age of 31.5 years. An isokinetic examination of the muscles was perfo...

The aim of this study was to investigate the effects of two training protocols on the isokinetic performance of athletes. The study was conducted in 38 athletes, (age 23.3 ± 3.6 years) participating in national level leagues of different sports, whose initial concentric hamstrings-to-quadriceps (conH/Q) torque ratio was lower than 0.5. During seasonal testing, an isokinetic measurement of knee ...

The primary aim of our study was to evaluate the strength ankle evertor muscles in patients who have undergone a lateral ligamentoplasty (which combined tensioning ligament group and reinforcing it with pediculated extensor retinaculum flap), using 2 measurement systems (isokinetic functional weightbearing test [MyoLux). Our hypothesis on treated side comparable that contralateral healthy side....

An “all-out” tethered running on the treadmill represents an alternative form of exercise used for the assessment of anaerobic capacity. Contrary to the well known and frequently used “all-out” test on the cycle ergometer (Wingate anaerobic test), there is a lack of information concerning the parameters of anaerobic capacity obtained from tethered running on the treadmill. The aim of our study ...
