Abstract
The invention pertains to a sports training device for improving the follow through of the lower body during a sport activity. The device includes a base having a top planar surface and a disk assembly removably coupled to the base and configured to receive a foot of a user. The disk assembly includes a first disk that is rotable between a first relaxed position and a second rotated position. Upon movement of the disk between the first relaxed position to the second rotated position, the disk is biased toward the first relaxed position. In some embodiments, the disk assembly is configured to be rotatable between a closed position wherein the disk is substantially coplanar with the top surface of the base and an open position wherein the disk is directed away vertically from the base upon rotation of the disk by the user's foot to the open position.
Description
- The present invention generally relates to the field of sports, and more particularly to a training device for improving the follow through of the lower body during a sport activity.
- Various types of sports require lower body movement and coordination for proper technique and form. In some sports, proper lower body movement requires that the rear foot be pivoted. For example, in baseball and softball, it is important for a player to pivot and push off the ball of the rear foot when pitching and batting. Similarly, in golf, it is important for a player to pivot the rear foot when swinging a golf club.
- Generally, for one to become skilled at baseball, softball, or golf, much practice is required. Practice typically includes proper pivoting of the rear foot for better body balance and necessary hip movement. Proper pivoting of the rear foot generally involves rotating the rear foot during a movement, be it either a ball pitch or batting/golf swing, at approximately a ninety (90) degree angle. Over time, the body movement and coordination resulting from proper pivoting of the rear foot results in better timing and maximum power for sports players.
- For example, in baseball, the player should rotate their back foot and allow the heel to come off of the ground when pitching or hitting. Although much teaching and coaching time is spent using example training and other reinforcement techniques, the techniques, while useful, generally do not emphasize the period of time directly before, during and after a swing or pitch. Thus, many players do not develop the proper form during a swing or pitch causing a loss of hitting power or an inaccurate throw, respectively.
- In golf, many players fail to perform a proper swing because they also do not rotate their body properly. For example, after a player hits a golf ball, in order to properly follow through, the player should rotate their torso and swing the club all the way up, finishing behind the back. At the same time, the player should rotate their back foot and allow the heel to come off of the ground while keeping the toes and the ball of the foot on the ground. A good player performs these techniques rhythmically and fluidly while maintaining proper balance. Many golf players, however, lose their balance during the swing and cause inconsistency when striking the ball. In addition, some players may lose their sense of timing during a swing when they fail to rotate and lift their rear foot. Thus, it is fundamental that a golfer rotate their lower body properly to achieve a good club swing.
- In the prior art, various types of devices have been proposed to improve lower body movement. For example, in U.S. Pat. No. 5,810,673 to Castleberry, a swing/training device having an upper and lower plate that rotate with respect to each other is disclosed. The device, however, allows the plates to rotate freely about each other. As such, the device does not train the player to develop the correct pivot angle for their rear foot.
- U.S. Pat. No. 5,318,290 to Sawyer discloses a golf/baseball swing training apparatus that also uses a rotational platform for allowing a foot of a user to pivot in conjunction with the platform. This device, however, is not portable and requires tools to pound spikes into the ground to set up the apparatus. In addition, there are no stoppers to impede the rotational movement of the platform.
- Thus, what is needed is a device that can be used to train a player to rotate their rear foot properly during a sport activity and thereby, improve a player's timing and sport skill level.
- The invention pertains to a sports training device for improving the follow through of the lower body during a sport activity.
