[Purpose] To investigate changes in hemodynamics during plantar flexion exercise at three different loads. [Subjects and Methods] The participants were 19 sedentary healthy males with a mean age of 20.4 years, mean body mass of 63.5 kg, mean height of 172.2 cm, and a body mass index of 22.4 kg/m2. Hemodynamics were measured using impedance cardiography in the sitting position before, during and after ankle plantar flexion at loads of 20, 50 and 80% of the maximum plantar flexor strength. [Results] Compared with their values before and after exercise, heart rate, cardiac output and total peripheral resistance showed significant changes during exercise at 80% exercise loads. Also, there were significant changes in heart rate, mean blood pressure, total peripheral resistance and stroke volume between before and after exercise. [Conclusion] During resistance exercise, recording of hemodynamic parameters might be a necessary safety measure. © 2017, Society of Physical Therapy Science (Rigaku Ryoho Kagakugakkai).
