The participants were categorized on the basis of their self-reported physical activity as sedentary group (no other activities, but at the most light walking ≤2 times/week), moderately active (walking or other light exercise at least 3 times/week, but no other more intensive activities) and active (moderate or vigorous exercise at least 3 times/week).
The recommended level of physical activity was defined as moderate intensive exercise for at least half an hour, five times a week (i.e. brisk walking, cycling or other forms of brisk exercise).
Guidelines on physical activity recommend longer duration of moderate-intensity physical activity to achieve the same health benefits as for vigorous intensive activities [ 13].
Two micro-seismicity based real-time warning systems have been established for predicting various intensities of rockbursts, such as slight, moderate, intensive and extremely intensive rockbursts.
Study results concerning leisure time PA, sports, physical exercise and risk of LBP are inconsistent: intensive activities are considered a risk factor for LBP, whereas moderate PA is, on the contrary, considered beneficial to health [ 41].
Current physical activity recommendation from the Centre for Disease Control CDCC) [5] suggests that adults participate in at least 2 days of muscle strengthening activities and 150 min of moderate intensity aerobic activity or 75 min of vigorous intensive physical activity each week.
The definition of activity used in the model was: undertaking a minimum of 150 min of at least moderate intensive PA or at least 75 min of vigorous intensive PA per week.
Premenopausal women usually perform more intensive activities.
Some relate that they have an inner sense of security, which allows them to judge whether it is safe to continue the same activity or whether it is better to replace intensive activity with more moderate activities.
You just need to do some moderate intensity aerobic activity.
