To begin with the bright side of endorsements by sports persons. Firstly, players can promote certain products in a better way because they themselves use some of these items in their line of work. For example, Kazakh volleyball player Altynbekova Sabina does the advertisement of clothes firm, which she consumes while playing the game. Because of this reason, his endorsement of the product sounds genuine. Secondly, players can make money by doing various types of advertisements. In general, advertisement companies give approximately 5-10 million dollars to the players who work for them. This is a great opportunity for them to convert their popularity and brand value into wealth.
