Are Punjabis more taller and more athletic than other Desis?

From my understanding of history punjab was at the frontier of India so foreign invaders who have invaded India in the past crossed through punjab so Punjabis had to develop a warrior lifestyle to fight off foreign invaders. Punjabis also have good diet. They also say that these foreign invaders marry into the ancestors that would make up the modern Punjabi population. Like the ancient Indo Scythians and Alexander the greats soldiers and Turkic people and Pashtuns did marry into the Punjabi population. So is that why Punjabis are taller and more athletic because many have pointed out first generations Punjabis in Canada get involved with sports right away like hockey which is pretty impressive.
