Two 4-minute periods (single 5-minute period for some events); Active wrestling required; passivity penalized
Why people argue about this
People often assume that each 4-minute period is a separate match with its own winner, which leads to misunderstandings about how points are scored and when matches end in Sport Sambo. Actually, these periods are just intervals for rest and scoring, and the final outcome depends on who accumulates more points over the two periods, not whether one side wins each 4-minute segment individually.
