Hey guys, today i tested my vertical leap and my 60 yard dash. I did it at my house, so not sure if this calculation is accurate. To find my vertical i videotaped it. Then i looked up Tim Collins vertical leap of 38.7 inches. I downloaded and converted it so i could count the frames. From the time his toes left the platform to the time they landed it took 25 frames. Then i counted mine and it took 21 frames. So i set up a proportion ( hey don’t they teach that in math class? ) like this, x being my vertical:

x 21

_ = _

38.7 25

(this didn’t come out the way i wanted. It is x over 38.7 equals 21 over 25.)

After this is solved it comes out to 32.5. Assuming my frame counting is correct, which i think it is because i have checked several times, wouldn’t this be the acccurate measurement?

As some additional info that may be helpful, my 60 yd time was 7.2. And i know this is correct. It wasn’t done by hand, but i used the program that came with my camera. It gives time to the nearest hundredth. From my first movement till my foot crossed the 60yd line, the time was 7.17. My vert leap compared to Tim Collins:
