radius

One of the two forearm bones, the other being the ULNA. The radius is on the thumb side and lies parallel to the ulna when the palm is facing forward. When the hand is rotated so that the thumb turns inward, the upper end of the radius rotates on a boss on the lower end of the upper arm bone (HUMERUS) but the lower end crosses over the ulna.

Every curve contained from 25 to 35 measurement points (taking into account curve radius) [18].
A main effect of curve radius was again found, F(2, 28) = 19.55, p < .001, MSE = .006, [[eta].sup.2] = .58, in which a significant linear trend across the three curves accounted for 96.2% of the variance.

A consistent finding in studies of speed choice in curves is that speed has a curvilinear relation to curve radius (see Kanellaidis, Golias, & Efstathiadis, 1990) and an inverse relation to lateral acceleration.
