Devices and method for increasing running performance
First Claim
1. A method of using a first running device and a second running device, the first running device being gripped by or removably affixed to the left hand and the second running device being gripped by or removably affixed to the right hand,each running device comprising:
- a closed inner chamber defined at least in part by a top inner surface and a bottom inner surface facing the chamber, the top inner surface and the bottom inner surface further defining a longitudinal axis extending from the top inner surface to the bottom inner surface,a moveable material disposed within the closed inner chamber and configured to provide a gap between the moveable material and the top surface when the moveable material is in contact with the bottom surface and to provide a gap between the moveable material and the bottom surface when the moveable material is in contact with the top surface,a housing containing the closed inner chamber and the moveable material, and configured to be gripped by or removably affixed to a hand;
the method comprising;
as the left foot is launching, raising both running devices such that the moveable material in the first running device is pushed against the bottom surface of the inner chamber of the first running device and the moveable material in the second running device is pushed against the bottom surface of the inner chamber of the second first running device;
when both feet are off the ground, lowering both running devices, such that the moveable material in the first running device changes from being pushed against the bottom surface to being pushed downward by the top surface of the first running device and the moveable material in the second running device changes from being pushed against the bottom surface to being pushed downward by the top surface of the second running device;
when the right foot is in contact with the ground, decelerating both running devices, such that the moveable material in the first running device collides with the bottom surface of the inner chamber of the first running device when the right foot is in contact with the ground and the moveable material in the second running device collides with the bottom surface of the inner chamber of the second running device when the right foot is in contact with the ground; and
as the right foot is leaving the ground, raising both running devices such that the moveable material in the first running device is pushed against the bottom surface of the inner chamber of the first running device and the moveable material in the second running device is pushed against the bottom surface of the inner chamber of the second first running device.

Abstract
A running device and method of using the device are disclosed. The device may include a moveable material within an inner chamber of the running device'"'"'s housing. In operation, a running device may be held in each hand and the runner may thrust both hands downward prior to landing and quickly bring the devices to a vertical stop after landing. Bringing the devices to a vertical stop may cause the moveable material to collide with the housing and increase the force exerted by the runner on the ground. A delay component may delay the peak force exerted by the material against the housing so that the translation of that force to the ground coincides with the peak force that the runner would have exerted against the ground in the absence of the devices.

10. A method of using a first running device and a second running device, the first running device being gripped by the left hand and the second running device being gripped by the right hand,
each running device comprising: -
a housing having a generally cylindrical outer surface and generally cylindrical inner side surface, an inner top surface, an inner bottom surface, the housing, inner top surface and inner bottom surface defining an inner chamber, a protrusion extending from the inner side surface into the inner chamber, and loose material disposed within the inner chamber, the method comprising; before the left foot launches from the ground, accelerating the upwards vertical velocity of each running device such that the loose material in each running device is pushed against the inner bottom surface of the inner chamber, after the left foot has left the ground and before the right foot makes initial contact, accelerating the downwards vertical velocity of each running device such that the loose material in each running device is pushed against the inner top surface of each running device, after the right foot makes initial contact with the ground, decelerating the downwards vertical velocity of each running device such that the loose material in each device collides with the inner bottom surface of the inner chamber, before the right foot launches from the ground and after decelerating the downwards vertical velocity of each running device, accelerating the upwards vertical velocity of each running device such that the loose material in each running device is pushed against the inner bottom surface of the inner chamber, and after the right foot has left the ground and before the left foot makes initial contact, accelerating the downwards vertical velocity of each running device such that the loose material in each running device is pushed against the inner top surface of each running device. - View Dependent Claims (11, 12, 13, 14)
