This study analyzed the activity profiles of elite amateur boxers across three weight categories (46-56 kg, 60-75 kg, 81-91+ kg) at the 2015 AIBA World Boxing Championships. The bouts were coded using Dartfish software to record punch types, targets, and outcomes. While there were no significant differences in punch output between winners and losers across weight categories, punch efficiency was found to be higher for heavy weight winners compared to light and middle weight losers. The results provide a profile of punch types and efficiencies within different weight categories that can inform future training approaches tailored to a boxer's specific weight class.
