Abstract: The relation between dilation of pupil size and heart rate response due to static muscle contraction were investigated in this study. The hand grip during three seconds were used as static muscle contraction. Hand grip contraction of three conditions were 30%, 50% and 100% of maximum hand grip of each subjects. a) Pupil size was found to be dilated by hand grip contraction. The stronger the hand grip contraction was made, the larger the pupil size was dilated. Dilation of pupil size in 100%max condition was merely 0.42mm in diameter. b) Heart rate were increased due to during three seconds hand grip contraction likewise pupil size. Similarly, the stronger the hand grip contraction was made, the larger the heart rate were increased. c) The response of pupil due to muscle contraction was sensitivity compared with heart rate response. It was speculated that the response of pupil comfort to as index of sympathetic nerve activity than heart rate response.
