This study investigated the BB muscle activity between the region of the endplate and distal tendon insertion (electrode placed on lower part of the BB muscle belly). [Subjects and Methods] Six right-arm dominant Asian subjects (n=6, 3 males and 3 females), age range 20-30 years, who were free from any musculoskeletal disorder in BB, participated in this study. EMG signals were recorded from 12 BB muscles (6 subjects × 2 arms) during two types of muscle contraction (concentric and eccentric). Mean ± SD was calculated and analysis of variance (ANOVA) was performed. [Results] The results indicate that, the dominant right arm (R) of both males (M) and females (F) showed significantly higher activity than non-dominant left arm (L). In addition, there were interactions between M(L) and M(R), F(L) and F(R), M(L) and F(L), M(R) and F(R), and both male BB and both female BB; but, no interactions were found between M(L) and F(R), and M(R) and F(L). We also discovered that eccentric contraction generates higher EMG signals than the concentric contraction of that muscle region. [Conclusion] These findings suggest that EMG data are random on the BB muscle area we investigated during arm movement. These results should be considered in biceps tendonitis rehabilitation, muscle coordination and other physiological measurements of the upper limb muscles. 2014-03-10T02:36:26Z 2014-03-10T02:36:26Z 2013-01 Article Journal of Physical Therapy Science, vol. 25(1), 2013, pages 3-6 0915-5287 https://www.jstage.jst.go.jp/article/jpts/25/1/25_JPTS-2012-258/_article http://dspace.unimap.edu.my:80/dspace/handle/123456789/32473 en Society of Physical Therapy Science |
