The
aim of present study was to compare electromyography activity of selected
leg-dominant lower limb muscles during stance phase of running on treadmill and
overground. Fourteen male students were selected as the available statistical
sample. The multivariate analysis of variance with repeated measures (MANOVA)
was used to compare the normalized RMS activation of selected lower limb
muscles between running surfaces in each of two phases: initial 50% and
terminal 50% of stance phase. The results of this study showed a significant
difference in total activity of selected lower limb muscles between the two
surfaces for initial 50% stance phase (P<0.05); so that while running on the
gym surface muscle activation level of rectus femoris, vastus medialis, vastus
lateralis, and biceps femoris was significantly higher than while running on
the treadmill surface (P<0.05). Although no significant difference in the
lower limb muscle activation level was observed for the terminal 50% of stance
phase between the two surfaces (P>0.05), while running on the gym muscle
activation level of rectus femoris, vastus medialis, vastus lateralis, and
lateral gastrocnemius was significantly higher than while running on a
treadmill (P<0.05). According to these results, instrumented treadmills may
be possibly useful in the designation of specific training programs for injured
persons to reduce the activity level of lower extremity muscles.
