Baseline characteristics of the college students.

	All (n = 112)	CG (n = 56)	IG (n = 56)	p a
Age	20.9 ± 1.3	20.8 ± 1.2	21.0 ± 1.4	0.379
Stages completed in 20mSRT	6.5 ± 1.8	6.4 ± 1.7	6.6 ± 1.8	0.523
Estimated VO2max from 20mSRT b	40.0 ± 5.3	39.7 ± 5.2	40.3 ± 5.4	0.523

Values are means ± standard deviation (SD). CG = control group; IG = intervention group; 20mSRT = 20-meter shuttle-run test. p ^a -value for comparison between groups by one-way analysis of variance (ANOVA). ^b Estimated maximal oxygen consumption (VO2max) was calculated using Léger’s equation for adults [15].
