Sources of signal-dependent noise during isometric force production.
It has been proposed that the invariant kinematics observed during goal-directed movements result from reducing the consequences of signal-dependent noise (SDN) on motor output. The purpose of this study was to investigate the presence of SDN during isometric force production and determine how central and peripheral components contribute to this feature of motor control. Peripheral and central ...
متن کاملThe preparation and production of isometric force in Parkinson's disease.
Subjects with Parkinson's disease (PD) and age-matched controls performed an isometric force production task, aiming at different target force levels without concurrent force feedback. Overall, PD subjects were as accurate as controls in attaining the target force levels, but executed the task differently. They had longer times to peak force and contraction durations, larger impulses and lower ...
متن کاملIsometric force production symmetry and jumping performance in collegiate athletes
Participation in sports can place numerous physical demands on the athletes who partake in them. Many of these sports may require the athlete to repeat the same motions countless times. Concerning a sport such as baseball or softball, a player may throw or hit with the same side of their body possibly leading to altered ranges of motion and strength asymmetries.1-3 Other sports may require the ...
متن کاملProgressive isometric force training
In ten growing male Wistar rats, isometric strength training for 69 days (3-6 times vertical gripping position on a wire-netting during 2 x 30 s, with progressive loading of the tail through a 50-200 g indwelling clip), fat mass and plasma leptin concentrations were lower on day 70 than in ten sedentary controls. Muscle mass and femoral trabecular and cortical bone mineral density were simultan...
متن کاملForce development during target-directed isometric force production in Parkinson's disease.
Performing various daily activities requires precise application and control of forces, which has been well addressed in neurologically healthy individuals. Recent experiments have demonstrated that in young, normal subjects generating rapid force pulses over various force amplitudes was accomplished by linearly increasing the rate of force development while keeping time to peak force approxima...
