Muscle fatigue has been defined as “any reduction in the force generating capacity of the total neuromuscular system regardless of the force required in any given situation” (Bigland-Ritchie and Woods, 1984). A reliable muscle fatigue measure has subtly emerged during maximal effort isokinetic contractions that has been able to highlight gender differences in quadriceps and hamstring torque gen...

The “isokinetic relationship” is a purported linear relationship among the enthalpies and entropies of activation along a series of reactions. The standard technique for determining whether an isokinetic relationship holds for a particular group of reactions is incorrect, and will “discover” the relationship where it does not exist. The paper describes an amusing example of its failure, shows w...

The aim of this study was to compare isokinetic strength performance profiles in elite soccer players across different field positions. A total of 111 elite international players of Polish Ekstraklasa (the top division in Poland) were examined during the 2010-2015 seasons. The players were classified into six positional roles: central defenders (CD), external defenders (ED), central midfielders...

The purpose of the present investigation was to examine the mechanomyographic (MMG) responses to maximal eccentric isokinetic muscle actions. Eight adult male volunteers [age 22 +/- 2 (SD) yr] performed maximal eccentric muscle actions of the leg extensors at 60, 90, 120, and 180 degrees /s on a Cybex 6000 isokinetic dynamometer. MMG was detected by a piezoelectric crystal contact sensor placed...

Shoulder isokinetic assessment: A critical analysis B. Forthomme, D. Maquet, J.M. Crielaard and J.L. Croisier Department of Physical Medicine and Rehabilitation, CHU Sart Tilman, Li ège, Belgium Objectives: The literature dealing with shoulder isokinetic assessment presents some contradictions in methodological aspects, protocol design and even muscles targeted [1]. Nevertheless, quantitative a...

The purpose of this study was to investigate the acute effects of foam rolling on quadriceps isokinetic and isometric force production as well as knee joint range of motion. Twelve healthy, light to moderately physically active college students volunteered for this study. They had different treatments on three separate days. Participants' non-dominant knee joint range of motion (ROM), quadricep...

PURPOSE Resistance exercise training (RET) and an additional intake of dietary protein supplements may improve muscle mass and muscular function, and reduce inflammatory markers. The types, amount, and timing of dietary protein supplements are important for the synergistic effects of resistance training and dietary protein supplements. We hypothesized that a 25.1 g protein complex supplement ta...

The aim of this paper was to outline a multilevel modeling approach to fit individual angle-specific torque curves describing concentric knee extension and flexion isokinetic muscular actions in Master athletes. The potential of the analytical approach to examine between individual differences across the angle-specific torque curves was illustrated including between-individuals variation due to...

OBJECTIVE Isokinetic strengthening is a rehabilitation technique rarely used in stroke patients. However, the potential benefits of force and endurance training in this population are strongly suspected. METHOD This literature review synthesizes the results of clinical trials on this topic. The research was conducted on PubMed, using "Stroke", "rehabilitation", "isokinetic", "upper limb" and ...

The medical diagnosis system described here uses underlying knowledge in the isokinetic domain, obtained by combining the expertise of a physician specialised in isokinetic techniques and data mining techniques applied to a set of existing data. An isokinetic machine is basically a physical support on which patients exercise one of their joints, in this case the knee, according to different ran...
