Effect of Calf Muscle Incremental Stretching to Maximal Extent on Peripheral Circulation Fumiko Ohmori, 1 Shizuyo Okuyama, 2 Yoshiho Muraoka, 3 Aki Mori, 4 Sakiko Suzuki, 4 Mayumi Mizumura, 5 and Atsuko Kagaya 1 1 Resarch Institute of Physical Fitness, Japan Women s College of Physical Education, Tokyo, Japan 2 Institute of Physical Education, Keio University, Kanagawa, Japan 3 School of Humanities, Meisei University, Tokyo, Japan 4 Graduate school of Humanities and Science, Ochanomizu University, Tokyo, Japan 5 Department of Performing Arts, Graduate school of Humanities and Science, Ochanomizu University, Tokyo, Japan Key words: calf muscle stretching, blood volume, medial gastrocnemius and soleus muscle The purpose of this study was to clarify the effect of calf muscle incremental stretching to the maximal extent on calf muscle blood volume (NIRS) and popliteal artery blood flow (the Doppler ultrasound method). The popliteal artery blood flow did not change significantly during incremental stretching. The total Hb of the medial gastrocnemius (MG) significantly (p<0.05) decreased above the range of 80% of the maximally extended position, whereas it significantly (p<0.05) increased in the soleus muscle (SOL) above 40% of the maximum during incremental stretching. In conclusion, the calf muscle blood volume during incremental stretching began to change at 40% of the maximally stretched position in the SOL and 80% of the maximum in the MG, increasing in the former and decreasing in the latter muscles, without a significant change in the upstream blood flow.
