In the published article, there was an error in the numbers reported in relation to the number of participants who met the physical activity recommendations.
A correction has been made to Results, “I would love to exercise every day, but I can't do it: the influence of work on physical activities”, Paragraph 2. This sentence previously stated:
Nevertheless, more than half of the participants (66.7%−12 men and 10 women) took part in physical activity at least once in a typical week, although fewer (39.4%−7 men and 6 women) met the recommendation of 150 min of moderate-intensity aerobic exercise or at least 75 min of vigorous-intensity aerobic exercise in a week (55).
The corrected sentence appears below:
The WHO physical activity guidelines recommend per week: 150 min of moderate-intensity aerobic exercise or 75 min of vigorous-intensity aerobic exercise; and muscle strengthening activities on two or more days (55). More than half of the participants (66.7%−12 men and 10 women) took part in recreational physical activity at least once in a typical week. Yet, many participants did not meet the guidelines despite most participants (81.8%−12 men and 15 women) performing moderate or vigorous intensity exercise, largely through incidental activity.
The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
