Doing that, we'll can attend his growth, got by the absolute values, for example, jumping 40 centimeters(15,80 inch) in thirteen's and pass to 44 centimeters(17,40 inch) with 14 years-old, we can do the same through the

Getting a Z of 1 (Z=1) means the person moves away, exactly one standard desviation up to population average. We can say he presents a result 84,13% higher than the one presented by the population or that just 15,87% of that population with same sex and age can get upper results.

A Z of 0 (Z=0) means the person got a result equal of standard reference. So, the more

The experiency with different groups( since sedentaries until olimpic athlete) enabled to create a practice results classification being:

Z VALUE | CONDITION |

> 2 | Excellent |

1 til 1,99 | Very Good |

0 til 0,99 | Good |

-0,99 til -0,01 | Regular |

-1 til -1,99 | Poor |

< 2 | Very Poor |

After we've got the Z indices, we'll be able to represent the values in a graphic called Z-Fitnessgram, where is possible to see all physical fitness. Through this graphic, it'll be possible to detect talents by comparing the person graphic with the graphic of an athlete(or an average of a sport).
