50 minutes (single continuous period — no halftime); No substitutions: players who exit (injury, ejection) are not replaced; Reduced-team play continues if one side has fewer players
Why people argue about this
People often assume that without a halftime and substitutions, matches would be brutal affairs with players exhausted quickly. But in Calcio Storico Fiorentino, the intense focus on maintaining control of the ball and quick passing means teams can still manage for 50 minutes without needing to rest or change up their lineup. The key is in how they adapt strategies within this strict timeframe.
