Abstract
A method to measure height of a vertical jump of a jumper. At least one switch is deactivated by the jumper stepping thereon. The switch is initially activated by the jumper jumping upward therefrom and thereafter deactivated upon return. A time period is measured while the switch is activated. The square of the activated time period is calculated and thereafter the result is multiplied by a constant to derive vertical jump height. Finally, the resultant vertical jump height of the jump is displayed.
Claims10
A method to measure vertical jump height of a jumper, which method comprises:
- measuring both take-off impulse force over a period of time and landing impulse force over a period of time of a jump of said jumper;
- measuring a time period between take-off and landing;
- converting said impulse force and time periods measurements into upward and downward velocities by integrating force over said time measurements;
- calculating vertical jump height from said velocities;
- and
- displaying said vertical jump height.
A vertical jump measuring device, which comprises:
- at least one normally open transducer adapted to deliver a signal and deactivated in response to a jumper stepping thereon;
- a timer connected to said transducer and adapted to receive said signal to measure a time period said transducer is activated while said jumper is in the air;
- a table which derives vertical height jumped from impulse force and time period measurements;
- means to display the resultant vertical height jumped from said table;
- and
- an output device connected to said means to display the resultant vertical jump height of said jumper obtained from said table.
A vertical measuring device, which comprises:
- at least one normally closed transducer adapted to deliver a signal and activate response to a jumper stepping thereon;
- a timer connected to said transducer and adapted to receive said signal to measure a time period said transducer is deactivated while said jumper is in the air;
- a table which derives vertical height jumped from impulse force and time period measurements;
- means to display the resultant vertical height jumped;
- and
- an output device connected to said means to display the resultant vertical jump height of said jumper obtained from said table.
