With pushups, the triceps engage and shorten as you push your body away from the floor. The name for this type of muscle movement is concentric contraction. In contrast, your triceps will tense and lengthen as you lower your body toward the floor. This type of muscle movement goes by the...
Knee flexion (front leg) during the down phase of a lunge: a) Is controlled by eccentric contraction of the knee extensors. b) Is controlled by concentric contraction of the knee flexors. c) Occurs passively without muscle action at the knee joint. d) No ...
These “voluntary pandiculations” begin with a concentric contraction: tension in the muscle increases while the muscle fibers shorten, bringing the origin and insertion of the muscle closer together. This is followed by aneccentric contraction, in which muscles are engaged while they lengthen under...

The primary endpoint was the change in concentric isokinetic knee extension peak torque (PT) at 60°/s on the OA side from baseline to 6 weeks. Secondary endpoints were changed in the following: concentric hamstring PT at 60°/s; eccentric quadriceps and hamstring PT at 30°/s; 10 m and...
Regarding the magnitude of asymmetry found in soccer players, it seems that the asymmetry shown in well-trained volleyball players does not differ significantly through an isokinetic test in concentric and eccentric contractions [42] nor those evaluated by a unilateral 1RM (9.9 ± 7.2% vs. 11.04 ...
s isokinetic torque and power on the CMJ in adolescent female volleyball players. The θPDFat a knee extension angle of 140 degrees were measured for 37 female post-pubertal volleyball players. Then, the players were assigned to either the flexible (n= 10) or inflexible (n= 14) groups ...
(EG,n= 10 players), who performed a maximal strength-training program, or to a control group (CG,n= 10 players), who only performed their regular soccer training. Physical fitness was measured at baseline and after the training program. In addition, the injury incidence, burden, training/...
