Free diving is a popular sport because there are many features of free diving such as sustainability, eco-friendly and
challenges to nature. Due to increased interest on this sport in recent years, the number of competitions is also increasing gradually.
On the other hand, the scientific reports on the understanding of breath-holding mechanisms and metabolism are still unclear. To
provide contributions on this phenomenon, glutathione peroxidase (GPX) was selected as a model enzyme because of its critical
importance in breath-holding. The GPX enzymes from human and free diving animals were compared by using bioinformatics
tools such as ProtParam, Swiss-Model, Clustal Omega and the results are discussed in the present paper. In conclusion, the specific
amino acid sequences can be considered in the selection of elite free divers for international competitions to get the best results.
However, it should be noted that special training methods should also be applied to have better breath-holding capacities.
