“…Seventeen [49, 51, 53-55, 61-63, 65-73] of the 20 studies found no significant and meaningful relationship between sex and change in PA, while one study showed men had a larger decline in PA than women [52]. Of the seven studies focused specifically on adoption of PA, six also showed null or not clinically meaningful relationships between sex and PA [49,54,61,63,66,73], while Cornelio et al [60] identified men as more likely to adopt PA over time than women. Similar findings were present in studies designed to examine PA maintenance, where five [49,54,61,63,66] of six showed null findings, yet Weiss et al [58] reported a larger relapse in PA for women than men.…”
