MentalMuscle: Mental Muscle
Description
Comparing actual movements to mental imaging movements
Format
A dataset with 32 observations on the following 3 variables.
Action Treatment: Actual motions or
Mental imaging motions
PreFatigue Time (in seconds) to complete motions before fatigue
PostFatigue Time (in seconds) to complete motions after fatigue
Source

In this study, participants were asked to either perform actual arm pointing
motions or to mentally imagine equivalent arm pointing motions. Participants
then developed muscle fatigue by holding a heavy weight out horizontally as
long as they could. After becoming fatigued, they were asked to repeat the
previous mental or actual motions. Eight participants were assigned to each
group, and the time in seconds to complete the motions was measured before
and after fatigue.
