Physiological Indices	Pre-Test	Post-Test	p	t	Effect Size
Systolic blood pressure (mmHg)	130.4 ± 3.6	135.2 ± 3.7	0.361	0.922	0.27
Diastolic blood pressure (mmHg)	78.0 ± 2.2	79.3 ± 2.1	0.667	0.433	0.13
Pulse rate (bpm)	80.7 ± 2.8	75.3 ± 2.4	0.155	−1.446	0.43
Salivary amylase activity (KU/L)	58.0 ± 16.4	13.2 ± 2.6	0.012 *	−2.636	0.78

Data are expressed as the mean± standard error. t: The t-test statistic for a paired sample t-test; p: The p-value (probability value) for the t-test statistic. * was considered significant at p < 0.05 paired-sample t-test. The effect size is reported by Cohen’s d.
