Explanation:

The Arjuna Awards are given by the Ministry of Youth Affairs and Sports, government of India to recognize outstanding achievement in National sports. Instituted in 1961, the award carries a cash prize of ? 500,000, a bronze statue of Arjuna and a scroll.
Over the years the scope of the award has been expanded and a large number of sports persons who belonged to the pre-Arjuna Award era were also included in the list. Further, the number of disciplines for which the award is given was increased to include indigenous games and the physically handicapped category.

As per the revised guidelines, to be eligible for the Award, a sportsperson should not only have had good performance consistently for the previous four years at the international level with excellence for the year for which the Award is recommended, but should also have shown qualities of leadership, sportsmanship and a sense of discipline.
