The aim of this study was to review the literature evaluating the effect of isokinetic training in patients suffering from shoulder impingement syndrome (SIS). Studies published up to March 2011 were located from the Pubmed, Scopus, Lilacs, Physiotherapy Evidence Database, and Cochrane Library databases using "isokinetic", "shoulder", and "impingement" as key words. Referenced studies were also...

Clinicians frequently want to know the pre-injury strength of an uninjured limb. The purpose of this study was to delineate the differences in bilateral isokinetic peak torque (PT) at 60 degrees and 240 degrees, and torque acceleration energy (TAE), average power (AP) and total work (TW) at 240 degrees during shoulder extension and flexion movements, and to develop a method to determine the exp...

BACKGROUND We aimed to analyze the range of motion (ROM) and internal rotation (IR) and external rotation (ER) isokinetic strength according to humeral retroversion of the dominant shoulder. METHODS We included 40 elite baseball players in Korea (OBP group: n=20 players with careers spanning >10 years, age: 19.37±2.21 years, height: 181.00±5.41 cm, weight: 84.58±7.85 kg; BBP group: n=20 playe...

Sport training has specific effects in the human organism's physiological and metabolic systems. A continuous workout produces adaptations in these systems, and improves development, stability and increased effectiveness in motor habit execution, achieved through a muscular strength increase. This type of evaluation determines the characteristics of Force-Velocity by means of Dynamometry and El...

CONTEXT Researchers have postulated that coactivation of the hamstrings during active knee extension assists the anterior cruciate ligament in maintaining knee joint stability by exerting an opposing force to anterior tibial translation. OBJECTIVE To compare the reciprocal coactivation of the hamstrings while performing low and high velocity isokinetic movements and two closed chain movements...

The purpose of this study was to compare four different methods of normalising electromyograms (EMGs) recorded during normal gait. Comparisons were made between the amplitude, intra-individual variability and inter-individual variability of EMGs. Surface EMGs were recorded from the biceps femoris, semitendinosus, vastus lateralis and vastus medialis of ten males and two females while they walke...

BACKGROUND Amino acid supplementation has been shown to potentially reduced exercise-induced muscle soreness. Thus, the purpose of this study was to examine if branched chain amino acid and carbohydrate (BCAACHO) versus carbohydrate-only sports drink (CHO) supplementation attenuated markers of muscle damage while preserving performance markers following 3 days of intense weight training. METH...

BACKGROUND The aim of the present study was to compare the changes in voluntary strength (isometric, concentric, and eccentric) and functional mobility in response to maximal isokinetic eccentric-only resistance training to those elicited by maximal isometric-only or maximal isokinetic concentric-only resistance training in older adults. METHODS Twelve women (73 +/- 7 years) and 18 men (73 +/...
