Ancient Macedonian sports were the same as the rest of the Greek sports

No, they are unrelated languages. The modern Macedonian language is a slavic language, related to Russian and Polish. The ancient Macedonian language was most likely a dialect of Greek, or at least related to Greek.

I think the question you are going for right now is, Why was the macedonian army so successful?

The Macedonian army (if you want to be specific, the Macedonian military under King Philip).

Phillip II of Macedon revolutionized the Macedonian army and warfare in the Ancient world. Phillip II made military service a full time occupation which allowed the men to train constantly and become a cohesive group. He also innovated the phalanx technique by introducing new weapons such as a longer spear and a two-handed pike.
