Pignet index = height (cm) – [weight (kg) + average thoracic circumference (cm)]. This is an advantageous index that has been used widely not only in studying but also in evaluating physical power. However, Pignet index is not yet an ideal index; it should be improved to measure physical power more accurately. Improved Pignet (Pignet-CT) = height (cm) – [weight (kg) + normal thoracic circumference (cm) + right calf circumference (cm)] + 50. This Pignet-CT index has been established by investigating 7955 Vietnamese (3755 male, 4210 female) aged over 16 years old. It has been shown that Pignet-CT index can evaluate physical power more exactly than Pignet index.

Study on 7955 people (3755 men, 4210 women) in Ha Noi city, Nam Ha, Hai Hung, Ha Bac and Ha Tay provinces and students of Ha Noi Medical College, Ha Noi Teacher's Collage and Ha Noi Agricultural Collage. The period of collecting data was 5 years from 1992 to 1997. In all age groups of two sexes, the circle of right legs were bigger than that in left legs. The circle of right legs had closely correlation and direct propertional with the lean mass of the body in all age groups of two sexes. The values of Pignet-C.T in two sexes had different within 3 first age groups which were significantly. On the math and reality study showed that: Pignet-C.T is the physical estimated index more exactly than Pignet.
