PURPOSE: To examine how different approaches of the current exercise recommendations for adults associates with VO2peak in a large healthy population. We further examined how a lower duration than recommended, if performed at very vigorous intensity, was related to VO2peak. METHODS: A total of 4631 healthy adults aged 19-89 years (2263 men and 2368 women), were tested for VO2peak (mean 44.3 and 35.9 mL·kg·min for men and women). Information on exercise habits was collected through a questionnaire including questions on frequency, duration and relative intensity (Borg 6-20 scale). A general linear model was applied to assess the associations between physical activity and VO2peak. RESULTS: VO2peak did not differ considerably between people who reported to exercise ≥150 min/week (average 216 min/week, VO2peak 45.2 and 36.5 mL·kg·min for men and women, respectively) with moderate intensity and people who reported 75-149 min/week (average 112.5 min/week, VO2peak 47.5 and 37.3 mL·kg·min for men and women) with vigorous intensity, but was higher than in people who reported inactivity (VO2peak 40.1 and 32.3 mL·kg·min for men and women) or low intensity exercise (VO2peak 41.2 and 40.1 mL·kg·min for men and women). Reporting exercise at very vigorous intensity, but with a duration of less than 75 min/week (average 49 min/week), was associated with a VO2peak that was similarly high (47.6 and 36.7 mL·kg·min for men and women). CONCLUSION: Our findings support current recommendations by showing that exercise of both "moderate intensity-long duration" and "vigorous intensity-short duration" was associated with similarly high VO2peak. Our results also suggest that exercising at very vigorous intensity may be beneficial for VO2peak even with a considerably lower total exercise time than expressed in today's recommendations.
