We recently reported that this cadence threshold had a classification accuracy of 73.3% for identifying moderate intensity during preferred pace overground walking in young adults. The purpose of this study was to evaluate and compare the performance of a cadence threshold of \u2265100 steps\/min for correctly classifying moderate intensity during overground walking in middle\u2010 and older\u2010aged adults.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Participants (<jats:italic>N<\/jats:italic>\u00a0=\u00a0174, 48.3% female, 41\u201385\u2009years of age) completed laboratory\u2010based cross\u2010sectional study involving an indoor 5\u2010min overground walking trial at their preferred pace. Steps were manually counted and converted to cadence (total steps\/5\u00a0min). Intensity was measured using indirect calorimetry and expressed as METs.
