Intensity of physical activity and subjective well-being: an empirical analysis of the WHO recommendations

This study examined the effect of different intensities of physical activity and the recommendations of the World Health Organization (WHO) on the subjective well-being (SWB) of adults in two age groups (18-64; 65+). Cross-sectional survey data from 28 European countries were used for the analysis (n = 21 008). Participation intensity was measured with the number of days and minutes of light (walking), moderate and vigorous activity. Another three dummy variables reflected how the WHO guidelines were met. Two-stage least square models were estimated with life satisfaction (measuring SWB) as the dependent variable. For 18- to 64-year-olds, walking (minutes and days/week) and vigorous activity (minutes/week) significantly added to SWB, while moderate activity (minutes/week) had a negative effect. Individuals in both age groups meeting the guidelines only for moderate activity and those meeting the guidelines for both moderate and vigorous activity or using a combination of both reported significantly higher well-being levels compared with those not meeting the guidelines. Physical activity recommendations aiming at improving individuals' mental health should reconsider the inclusion of light-intensity activity, the interchangeability of moderate and vigorous activity, and the fact that more physical activity does not lead to better outcomes for all intensities and age groups.
