P4430Physical activity in leisure time: complying with the recommendations of clinical practice guidelines increases maximum oxygen consumption

Abstract Introduction/Objectives The promotion of physical activity is a universal recommendation for prevention of cardiovascular diseases. Clinical practice guidelines recommend at least 150 min/week of moderate or severe physical activity or ≥75 min of severe intensity.Our objective was to analyze whether reaching the physical activity levels recommended in the clinical practice guidelines evaluated by validated questionnaires and accelerometry, is associated with higher level of VO2 max. Methods We conducted a prospective cross-sectional study of 243 participants in the PREDIMED PLUS study (site: Vitoria-Gasteiz), (82 women), 65±4,9 years old, with metabolic syndrome and overweight/obesity. They performed a maximum exercise testing with expired gas analyses. Physical activity in leisure time was evaluated using subjective methods: self-reported questionnaires REGICOR and RAPA 1 and objective methods: chair test and accelerometry (91 subjects). Sedentarism was analyzed with the Nurses Health Study questionnaire and accelerometry Results Subjects who claimed to comply with the recommendations of the PA guidelines in the REGICOR questionnaire achieved higher maximum oxygen consumption (21.3±4.6 vs 18±4.4 ml/kg/min; P
