Table 4 Summary of school-level measures estimated over two years among FLEX PA program schools

	100 Mile Club	CHALK/Just Move
Randomized cohort of FLEX schools:	N = 7	N = 6
Any implementation Year 1	71.4%	100%
Any implementation Year 2	42.9%	100%
Implementation cohort of FLEX schools	N = 5	N = 6
CHAMPIONS/TEACHERS	n = 5	n = 26
^aImplementation
% of schools offering core PA program elements to standard	40.0%	19.2%
% of schools offering any enhanced PA program elements	60.0%	65.4%
Implementation score per school (mean, range)	2.0 (1.5–3)	1.9 (1.5–2.33)
^bDose Delivered
PA program minutes offered per week per school (mean, range)	34.9 (23.0–45.5)	19.7 (11.1–39.4)
^cDose Received	n = 55 students	n = 160 students
MVPA minutes (mean, SD) per session	9.6 (4.2)	0.5 (0.8)
LPA minutes (mean, SD) per session	4.0 (3.0)	2.3 (1.7)
Total PA minutes (mean, SD) per session	13.6 (5.0)	2.7 (2.2)
Sedentary minutes (mean, SD) per session	0.4 (1.3)	4.0 (2.7)
Average length of session in minutes (mean, range)	25.0 (20.0–30.0)	6.2 (3.0–11.0)
^dReach
% of students reached per participating school (range)	31.2% (16.7–62.5%)	54.0% (34.4–100%)
Mean number of students reached per participating school	59	67
^eReceptivity	n = 3	n = 19
% of champions/teachers who indicated they would do program again	66.7%	89.5%
STUDENTS	n = 285	n = 241
Receptivity
% of students who indicated they liked the program	72.7%	69.2%
% of students who indicated they would do it again	80.8%	91.6%

^aImplementation Score = Score (0–3) based on estimate of the extent to which essential and enhanced PA program elements were implemented to standard per school (see Table 1 for detail)
^bPA Program minutes offered per week = based on estimated number of minutes that students were exposed to PA program per week per school averaged across two years of implementation
PA Program minutes planned per week = based on estimated number of minutes that champions/teachers reported planning to offer of PA programming (at baseline prior to program start)
^cAverage minutes children engaged in MVPA during program session; 100 Mile Club represents 2 schools, CHALK/Just Move represents 8 classrooms from 2 schools
^dReach = estimate based on maximum number of students exposed to the PA program per school per two years of implementation, estimate based on reported number of participants from surveys and for 1 school from direct observation
^eChampion/teacher receptivity: 100 Mile Club represents 3 schools, CHALK/Just Move represents 19 teachers from 5 schools
