Table 2.

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

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 -)

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).
