Lightweight rowing – the most commonly used term for the weight category in rowing’s often bifurcated categorisation system – is under credible threat of being eliminated at virtually all levels of rowing in Canada and the U.S. The health concerns associated with weight loss reflect the most problematic aspects of lightweight rowing, where the acceptable limits of harm that one must tolerated in sport is brought into question. Also, such category protection seems arguably unnecessary, especially for lightweights who are nearly (...) as competitive as their openweight counterparts. This prompts reflection on the purpose and policies behind these categories. The justification for weight categories is scant or has simply been assumed as legitimate within the status quo. In the absence of any constructive debate on the topic, I will attempt to articulate the neglected rationale for why lightweight rowing ought to exist despite its apparent problems. In doing so, suggestions for further rules and policy improvements to lightweight rowing will be identified. (shrink)
