Sealed pedometery, worn over 7 days, was used to determine physical activity (PA). PA was categorized into three groups (low\u2009=\u20092,501\u20135,000; medium\u2009=\u20095,001\u20137,500; and high=&gt;7,501 steps\/day).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Results from a series of 2 (gender) \u00d7 3 (PA dose) way analysis of covariance (ANCOVA), controlling for age, indicated dose\u2013response effects of PA for all functional fitness tests where participants classed as high PA had higher scores for arm curl, chair stand, 6 minute walk, back scratch, and sit and reach and lower scores for the timed up and go test compared to those classed as low and medium PA. There were also significant main effects for PA dose for BMI, WC, and body fat %.
