Andrei Pulyaev blames Azamat Murzakanov's loss on cardio conditioning

Coach Andrei Pulyaev believes cardio preparation was the key factor in Azamat Murzakanov's defeat to Paulo Costa. Pulyaev expressed disappointment that Murzakanov lost on his birthday and noted he himself is not a cardio machine. He also questioned how Costa recovered so well between the second and third rounds, noting Costa appeared tired but came out fresh for the third round. Murzakanov suffered the loss in his move up to light heavyweight. The post suggests cardio was the decisive factor rather than skill or strategy.
