Table 2 Ability of PAR and SWA to identify exercisers and non-exercisers against a reference standard

From: Accuracy of physical activity assessment during pregnancy: an observational study

Test Outcomes Reference Exercise Status
  Exerciser Non-exerciser
PAR exerciser 12 (True +) 24 (False +)
PAR non-exerciser 1 (False -) 15 (True -)
SWA exerciser 13 (True +) 36 (False +)
SWA non-exerciser 0 (False -) 3 (True -)
  1. Test outcomes based on a cut-off of more than 150 minutes of moderate-to-vigorous physical activity per week compared against the reference standard for exerciser vs. non-exerciser. (PAR = physical activity record; SWA = SenseWear® armband; + = positive; - = negative).
