This analysis system utilizes measurable data as a tool to assist coach and/or athlete in evaluating technical efficiency of pole vault and long jump techniques.  The intent is to pinpoint key areas for future development.  Most of the data is entered and reported as imperial measure (feet and inches) as the primary audience will most likely be the US athlete or coach.  Velocities are to be entered in metric measure (meters per second) as much of the reporting of elite athlete results have been presented in this fashion.  A conversion table is included at the bottom of this spread sheet to assist as needed.   It is important to note that efficiency is only a measure of excellence, not a limit of performance.
Pole Vault   1 Enter data: name, date, standing height, grip height (bottom of the pole to top of the top hand),  recorded velocities, and best vault or studied vault.          
    2 The pole run efficiency calculation is made by determining the "cost" to running speed due to pole carry.  A 5% loss in running velocity is exemplary and rated at 100%.         
    3 Runway efficiency is comparison of actual runway velocity (competition vault) with a "fly in" with the pole on the track:  runway velocity / track velocity x 100.        
    4 Runway velocity calculations on vaults may be made by timing from video a 5 meter segment, 10-5m men / 9-4m women from the back of the box, and velocity (t/d) compared to fly time w/pole.    
    5 Projected heights, from track and runway velocities, are made via research results of Dr. Peter McGinnis correlating running velocity with the pole and height vaulted - adjustments made for athlete's standing height.
    6 Grip and push off efficiency are calculated by assuming a push off of 35" for women and 42" for men as the projected best thereby establishing a basis for efficiency.        
    7 Vault height efficiency is the percentage of the projected best vault (based on research by Dr Peter McGinnis) with the height athlete has vaulted (actual best/projected best  x 100).      
    8 Analyze the numbers paying special attention to hand grip and push off efficiency.  It is common for vaulters to increase grip height when the real goal should be grip efficiency
