Isokinetic contraction is the muscular contraction that accompanies constant velocity limb movements around a joint. The velocity of movement is maintained constant by a special dynamometer. The resistance of the dynamometer is equal to the muscular forces applied throughout the range of movement. This method allows the measurement of the muscular forces in dynamic conditions and provides optim...

Suprascapular nerve palsy has been frequently reported in athletes, particularly baseball pitchers, volleyball players, and weight lifters, but it is easily overlooked during the evaluation of shoulder pain. Entrapment of the suprascapular nerve is usually suspected only after atrophy is noted. The presence of painless weakness of the external rotator muscles should alert the clinician to the p...

BACKGROUND The associations between pain, lower extremity strength, and aerobic conditioning have not been widely investigated in adults with fibromyalgia (FM). The principle objective of this study was to investigate the relationship between pain severity and knee strength in patients seeking treatment for FM. A secondary objective was to investigate the relationship between pain scores and ae...

PurposeTo evaluate clinical outcomes of the contralateral, nonoperative limb in patients undergoing contralateral hamstring (HS) autograft harvest compared with ipsilateral HS alone.MethodsThis study included 96 who underwent isolated anterior cruciate ligament reconstruction (ACLR) using 4-stranded (n = 85) or augmented 13) due to inclusion graft diameter <8 mm. Isokinetic flexion and extensio...

To achieve maximal force output, clinicians and coaches have been experimenting with upper extremity plyometric exercises for years, without sufficient scientific validation of this training method. The goal of this study was to examine the effects of an 8-week course of high volume upper extremity plyometric training on the isokinetic strength and throwing velocity of a group of intercollegiat...

Purpose: Correct proprioceptive information and muscle balance of the ankle joint muscles are essential in preventing sports injuries. This study aims to investigate effect closed kinetic chain exercises on proprioception inversion/eversion strength imbalance track field athletes with medial tibial stress syndrome. Methods: was a randomized controlled trial study. In present study, 22 male hist...

The aims of the study were to investigate the differences in kinematics and kinetics between the dominant and nondominant leg during single-leg jumps without arm swing, and to determine the relationship between bilateral asymmetry in isokinetic knee strength and the single-leg jump. Isokinetic knee strength and single-leg jump kinematics and kinetics were measured in 11 male participants. The b...
