Table 3.

Model results for day 1 (pre-submaximal exercise) and day 2 (post submaximal exercise).

	Pre-exercise (day 1)	Pre-exercise (day 2)
Accuracy	80.9%	76.1%
10x cross validation frequency	65%	57.5%
Sensitivity	87.5%	76.9%
Specificity	76.9%	75%
PPV	70%	83.3%
NPV	90.9%	66.7%
Significance as determined from Shuffle Test	p < 0.01	p < 0.05
Shuffle test average	44%	46%
Shuffle test mode	37.5%	43.5%

The accuracy and 10x cross validation frequency represent the corresponding model accuracy and accuracy after being ran through 10 smaller sub samplings of the initial testing set.
