Body Mass Index (BMI) - a fallacy


BMI (Body Mass Index) is calculated as = weight in kgs / (ht in metres)^2. I collected some data on some leading athletes in the world and calculated their BMI`s. If BMI above 25 is taken obese then Usain Bolt, Rafael Nadal and Roger Federer are obese and Tendulkar is on the verge of obesity ! Hence don`t worry about the BMI which I`ve felt for long is farcical.


Athlete
Wt (kg)
Ht
Ht (cms)
BMI
Usain Bolt
94
6"5"
1.93
25.37
Rafael Nadal
85
6"1"
1.83
25.52
Roger Federer
85
6"1"
1.83
25.52
Sachin Tendulkar
64
5"5"
1.63
24.24



The area of concern should be the fat content. Leading athletes are between 10 – 15%.
