Abstract: An athletic support device in the nature of a brace for use in bowling, having a casing that extends along a portion of the hand and/or wrist, means for coupling the casing to the hand, at least one inflatable bladder associated with the casing located at the position or positions where support is desired, and means for providing gas to the inflatable bladder so that the bladder may be inflated to provide support to the hand and/or wrist, as desired. The device includes means for deflating the bladder or bladders, so that the level of support provided may be adjusted to a desired level. The bladders may be incorporated into conventional support device designs, such as gloves, braces, and wraps. Preferably, bladders are associated with the casing at one or more of the following areas: palm area, wrist area, or finger area. In this way, the device may be tailored to the bowler's hand or to provide an optimal position of the hand and/or wrist for a desired delivery of the ball.
