• Resumen

  • AB Purpose: The objective of this study is to examine how different approaches of the current exercise recommendations for adults associate with V[spacing dot above]O2peak in a large healthy population. We further examined how a lower duration than recommended, if performed at very vigorous intensity, was related to V[spacing dot above]O2peak. Methods: A total of 4631 healthy adults age 19-89 yr (2263 men and 2368 women) were tested for V[spacing dot above]O2peak (mean = 44.3 and 35.9 mL[middle dot]kg-1[middle dot]min-1 for men and women, respectively). Information on exercise habits was collected through a questionnaire, including questions on frequency, duration, and relative intensity (Borg scale 6-20). A general linear model was applied to assess the associations between physical activity and V[spacing dot above]O2peak. Results: V[spacing dot above]O2peak did not differ considerably between people who reported to exercise >=150 min[middle dot]wk-1 (average = 216 min[middle dot]wk-1, V[spacing dot above]O2peak = 45.2 and 36.5 mL[middle dot]kg-1[middle dot]min-1 for men and women, respectively) with moderate intensity and people who reported 75-149 min[middle dot]wk-1 (average = 112.5 min[middle dot]wk-1, V[spacing dot above]O2peak = 47.5 and 37.3 mL[middle dot]kg-1[middle dot]min-1 for men and women) with vigorous intensity, but it was higher than that in people who reported inactivity (V[spacing dot above]O2peak = 40.1 and 32.3 mL[middle dot]kg-1[middle dot]min-1 for men and women) or low-intensity exercise (V[spacing dot above]O2peak = 41.2 and 40.1 mL[middle dot]kg-1[middle dot]min-1 for men and women). Reporting exercise at very vigorous intensity but with a duration of less than 75 min[middle dot]wk-1 (average = 49 min[middle dot]wk-1) was associated with a V[spacing dot above]O2peak that was similarly high (47.6 and 36.7 mL[middle dot]kg-1[middle dot]min-1 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 V[spacing dot above]O2peak. Our results also suggest that exercising at very vigorous intensity may be beneficial for V[spacing dot above]O2peak even with considerably lower total exercise time than expressed in today's recommendations.
