Concentric and eccentric: muscle contraction or exercise? New perspective.A letter to the editor is presented concerning the misuse of the terms eccentric and concentric exercises that are published in other journals.PaduloSportJohnnySportKarim
By utilizing a special 'sledge' apparatus which was connected to a force-plate, eccentric and concentric exercises were isolated so that only one form of contraction of the leg extensor muscles (either eccentric or concentric) was performed in a single exercise set of 80 contractions. A total ...
In both sexes, the functional ratios (ERecc/IRcon) were lower than the ideal to prevent joint overloading. Exercises involving concentric and eccentric strengthening of external rotators are necessary to restore shoulder imbalances, especially for females tennis players. 展开 ...
The consequences of a single bout of heavy eccentric exercise with and without repeated concentric exercises on MRI images, serum CK levels and markers of inflammation were studied. Two groups (ECC and ECCON), each consisting of 18 male volunteers, performed 70 eccentic contractions of the quadri...

CONTEXT: Rehabilitation protocols involving eccentric resistance exercise performed with loading more than 100% concentric 1-repetition maximum are effective in increasing muscle function in both healthy and injured populations. The mode of eccentric exercise (isokinetic versus isotonic) may be an important...
The effects of bungy weight training on muscle function and functional performance Eccentric strength training is thought to be important for improving functional performance. A form of training that may enhance the eccentric training sti... J Cronin,P Mcnair,R Marshall - 《Journal of Sports Science...
eccentric exercises. eccentric-concentric loading and, isometric exercises are indicated to reduce and manage tendon pain. Purpose of the Study To compare the effectiveness of eccentric training, eccentric-concentric training, and eccentric-concentric training combined with isometric contraction in the ...
Purpose: To analyze vastus medialis obliquus (VMO) and vastus lateralis (VL) muscle activity during the concentric and eccentric phases of a lateral step-up exercise. Design: Repeated-measures. Dependent variable: the integrated electromyogram measured as a percentage of the maximal voluntary isometric...
1. Concentric/eccentric fitness and rehabilitation apparatus which comprises: a base; a structure secured to said base at a lower end and having an elevated upper end; a seat at said lower end for supporting a user; a weighted carriage for movement along said structure and engagable by a ...
