Abstract
This study determined effect of automobile seat backrest inclination on lattisimus dorsi
muscle electromyographic (EMG) activity. Myoelectric activity was determined at two seat
backrest angles (90 degrees and 100 degrees inclinations). Twenty-one (21) participants
were engaged in the study. Electromygraphic activity at 90 degrees inclination had slope
value of -0.065 mV/minute while 100 degrees had slope value -0.044 mV/minute.
Myoelectric data indicated activity at 100 degrees was lesser than at 90 degrees for
latissimus dorsi muscles. Results of the experiment were significant (P=0.01). Myoelectric
results indicated that activity of the latissimus dorsi muscles decreased with increase in
backrest angle.
