Table 5. Group average and standard deviations of PRP for baseline (BL) and FI conditions.

Group	BL Mean	FI Mean	Mean Difference	BL SD	FI SD	SD Difference
0-0-X	1.88	1.96	0.08	4.49	4.94	0.46
0-15-X	1.93	3.35	1.42	2.58	4.43	1.85
0-30-X	2.32	6.81	4.49	3.18	9.98	6.80
0-60-X	2.28	5.99	3.70	4.08	11.8	7.75
0-120-X	3.17	3.78	0.61	4.64	8.53	3.90

PRPS are expressed in seconds. Baseline group averages imply roughly equal groups prior to the condition change. The 0-15-X and 0-30-X groups' standard deviation (SD) indicates non-homogeneous data during the FI condition. An increase in group average PRP is observed.
