A study proves that fishes are better athletes than people and any other species living on Earth because of such better oxygen delivery mechanism they naturally have.

As reported by The TeCake, an athlete has to deliver oxygen all throughout the body effectively and fishes are best at it -- giving them the edge over other athletes, according to scientists.

Jodie Rummer, the lead researcher from the Australian Research Council's Centre of Excellence for Coral Reef Studies at James Cook University, said that the fish's mechanism used in delivering oxygen is nearly 50 percent (or 50 times) more effective when compared to men. Rummer also said that the hemoglobin and protein transfer oxygen to tissues through blood and fishes' hemoglobin and proteins are more sensitive toward change in pH level as compared to humans or other animals.

Hence, the highly effective mechanism helps fishes to escape from their predators at critical situations. It can also be noticed that there is scarcity of oxygen in the water but fishes can double or triple the delivery of oxygen to save themselves from certain predators.

As noted as well by Phys.org, researchers have been using the rainbow trout to investigate the delivery of oxygen in fish for the past decade. They have first discovered and tested this specific mechanism by monitoring muscle oxygen levels in real time in trout.

Researchers now determined just how the fishes' system is so powerful that can be and have been compared to the results of human medical studies. The system can make the fishes live in all kinds of conditions whether warm or cold water as well as whether water with low or high oxygen levels, Rummer added.

Therefore, this trait can particularly let the fishes perform as even the best athletes in the world, which can swim in a long distance and at a faster pace and speed, too. They have even adapted and evolved for the past 400 years.

The study has been published in the Journal Plos One.
