Engine is a vital cog in the wheel of building and developing a championship caliber professional boxer and rounds are important.
A world championship professional boxing match happens over twelve three-minute rounds, far, far longer in duration that amateur boxing round duration at the end of the day.
This is a long time to be flat out fighting on full power with only one minute rest in between rounds.
This in many ways is what separates amateur and professional boxing completely.
Back in the day title fights in pro boxing were actually fifteen three minute rounds but due to health and safety, it was decided that twelve three minute rounds were best.
Some boxers don’t tire because of the following:
- Long distance road work in training
- Living the life of a boxer away from the sport (no boozing or smoking or drugs)
- Pacing themself in the fight and not wasting punches
- Appropriate cardio training outside of roadwork before a fight
- Some fighters have a naturally better gas tank and engine than others
At the moment in current fights in professional boxing cardio remains very important.
It has let some fighters down a bit in big fights notably recently.
Jake Paul took Anthony Joshua six rounds at heavyweight before Christmas but said his cardio let him down — it did.
But there are world championship fights where it still makes the difference as well.
Vital.
