In most Olympic sports, a player can only win one medal per event. For example, in athletics, a runner can only win one medal per race. Similarly, in gymnastics, a gymnast can only win one medal per apparatus. However, in team sports such as basketball, volleyball, and football, each player can win a medal if their team wins a medal.

There are also some exceptions where a player can win multiple medals in the same event. For example, in swimming, a swimmer can participate in multiple events, and if they win medals in each event, they can win multiple medals. Similarly, in track cycling, a cyclist can participate in multiple events and win multiple medals.

Another way a player can win multiple medals is by participating in different disciplines within the same sport. For example, in modern pentathlon, a player participates in five different events, and if they perform well in each event, they can win multiple medals.

It is also worth noting that in some cases, multiple players can win the same medal. For example, in a team sport, all members of the winning team receive a medal. Similarly, in some events such as equestrian, the rider and the horse both receive a medal.

Overall, the number of medals a player can win at one time depends on the rules of the sport and the number of events in which they participate. In most cases, a player can only win one medal per event, but there are some exceptions where a player can win multiple medals in the same event or across different events or disciplines.
