In general, it appears that patients with RA spend more time in light and moderate activities and less in vigorous activities than controls.
"Low activity" represent "one day a week or less" or "one hour a week or less"; "moderate activity" represent "2 3 days a week" or "2 3 hours a week"; "high activity" represent "four days a week or more" or "four hour a week or more" (Table 1).
During the free-living period, more time was spent in light activity (10.3 vs. 7.2 h, P = 0.005), with less sedentary time (13.0 vs. 14.9 h, P = 0.047) and less moderate activity (27 vs. 121 min, P = 0.022).
Nutrition expert Heather Mangieri, RD, CSSD, Sports Dietitian and author of her upcoming book Fueling Young Athletes, says that "most everyday exercisers participating in a one-hour or less moderate activity will have enough fuel stores".
There were three categories: low activity (1-2 times a month or less), moderate activity (1-3 times a week) and high activity (more than 3 times a week).
In comparison with our published national survey of clients attending a Stop Smoking Service [ 11] and advisors [ 10], clients in the present study were comparable on age, sex, BMI, cigarettes per day before current quit attempt and times quit smoking in the last year, but did more vigorous physical activity, less moderate physical activity and were less ethnically diverse.
There were three categories of physical exercise: low activity (1-2 times a month or less), moderate activity (1-3 times a week) and high activity (more than 3 times a week).
The answers were recoded into three categories: "low activity" represented "one day a week or less", "moderate activity" represented "2 3 days a week", and "high activity" represented "4 days a week or more" [ 30, 31].
Group 2 included 44.4% men, 55.6% women, 62.4% married, 39.5% smokers, 33.2% who consumed alcohol at least until last month, 6.9% who were barely physically active, 26.4% with moderate activity and 1.7% with less than primary education.
For the current study, accelerometer data indicated that the adolescents were engaged in low levels of moderate-to-vigorous physical activity (less than 30 minutes daily) and almost half of the adolescents (43 percent) were either overweight or obese.
