Fixed-effect adjusted coefficients for each muscular strength and endurance predictor variable on MetS.

Predictor variable	Adjusted β-coefficienta	(95% C.I.)b
Middle tertile push-ups	0.23	− 1.26, 1.73
Upper tertile push-ups	− 0.17	− 1.93, 1.57
Middle tertile curl-ups	− 2.06	− 3.31, − 0.82
Upper tertile curl-ups	− 2.01	− 3.29, − 0.78
Middle tertile composite (push-ups + curl-ups)	− 2.59	− 4.23, − 0.95
Upper tertile composite (push-ups + curl-ups)	− 1.57	− 3.20, − 0.16

Note: ^aβ-coefficients adjusted for estimated VO_{2 Peak}, classroom, and school level clustering; ^b 95% C.I. stands for the 95% Confidence Interval; Bold denotes statistical differences compared to the lowest tertile, p < 0.05. Data were collected during the 2014–2015 and 2015–2016 academic school years from five schools located from the state of Utah in the U.S.
