El fin de semana pasado se vivió una de las peleas de boxeo más emocionantes de los últimos tiempos, y de lo que se sigue hablando hasta hoy es del fulminante golpe que el mexicano Juan Manuel Márquez le metió al filipino Manny Pacquiao para noquearlo.

Márquez, de 39 años, consiguió la victoria más importante de su carrera luego de conectar un potente gancho de derecha a la mandíbula del llamado "Pac-Man". Quienes atestiguaron el golpazo, quedaron impactados por su efectividad y posteriormente, preocupados por la integridad del que quedó tumbado en la lona.

SportsCience de ESPN se dio a la tarea de analizar el mencionado derechazo, y en un magnífico video desmenuzan cómo es que Márquez hizo para atacar a su rival y cuáles fueron los efectos del impacto recibido por Pacquiao. La imagen en cámara lenta es algo que nadie se debe perder.
