- Note. P values are based on independent t-tests. Values are presented as mean ± standard deviation. METs = metabolic equivalents. Activity intensity (METs) thresholds = sedentary (<1.5 METs), light (1.5-2.9 METs), moderate-to-vigorous (≥3 METS), and total physical activity (≥1.5 METs). SF-36 scores are standardized to a population normal distribution with a mean of 50 and standard deviation of 10 to provide context for reported degree of health-related quality of life impairment [12].
