It has generally been assumed that the blood flow through human muscle during rhythmic exercise cannot be determined with the plethysmograph (Abramson, 1944). We have, however, been able to make such determinations in special circumstances. The new method has been used in experiments on the mechanical effect of rhythmic contraction on muscle blood flow. Kramer, Obal & Quensel (1939) showed that maximal rhythmic contractions obstructed the flow in dog's muscle. A. V. Hill (1948 a, b) found that the tension in strongly contracted frog muscle was 100-300 mm. Hg. The work of Grant (1938) and others on sustained human contraction left little doubt that rhythmic contractions per se would restrict blood flow in human muscle.
