A variable gravity training device allows a user to train skills in controlling a sports device. The training device has a stationary base (1), a movable support bar (2), and a sports device (6), for example, a ball, a badminton birdie, or a volley ball affixed to the end of the bar. The support bar is weighted or extendable, so that the amount of force required to move the sports device is reduced. The support bar also reduces the speed with which the sports device returns to its home position via force adjustment means (3). The force adjustment means are coupled to the support bar and can be adjusted, so that the conditions governing the sports device correspond to real playing conditions. |
