Trunk muscle activity while lifting objects of unexpected weight.

OBJECTIVE To determine trunk muscle activity when lifting an object of greater weight than expected, which may contribute to the development of low back pain. DESIGN Electromyographic evaluation of trunk muscle activity. SETTING University of Tsukuba, Spine laboratory. PARTICIPANTS Eleven healthy men with a mean age of 24 (SD 2) years. INTERVENTIONS Trunk muscle activity was measured wh...

Cognitive-Motor Interference While Grasping, Lifting and Holding Objects

In daily life, object manipulation is usually performed concurrently to the execution of cognitive tasks. The aim of the present study was to determine which aspects of precision grip require cognitive resources using a motor-cognitive dual-task paradigm. Eighteen healthy participants took part in the experiment, which comprised two conditions. In the first condition, participants performed a m...

Changes in Muscular Activity While Imagining Weight Lifting Using Stimulus or Response Propositions

Investigating emotional imagery, Lang (1977, 1979) proposed a dichotomy between stimulus and response propositions. In this study, Lang's model is applied to movement images of lifting of 4.5 and 9 kg weights. Twenty-two male and 17 female students participated in the study. During the imaginary lifting of the weights, the electromyographical activity (EMG) of both biceps brachii muscles were a...

Brain activity during predictable and unpredictable weight changes when lifting objects.

When humans repetitively lift the same object, the fingertip forces are targeted to the weight of the object. The anticipatory programming of the forces depends on sensorimotor memory representations that provide information on the object weight. In the present study, we investigate the neural substrates of these sensorimotor memory systems by recording the neural activity during predictable or...

Trunk Muscle Activity during Stability Ball

The purpose of this investigation was to compare trunk muscle activity during stability ball and free weight exercises. Nine resistance-trained men participated in one testing session in which squats (SQ) and deadlifts (DL) were completed with loads of approximately 50, 70, 90, and 100% of one-repetition maximum (1RM). Isometric contractions during 3 stability ball exercises (quadruped (QP), pe...
