Maximal physical capacity of animal groups in a timed swim test at the start and end of the study.

Group	Swim time (min)		Differences (%)
	Initial week	Final week
C	16.41 ± 4.45	22.02 ± 11.77	↑34
E	30.98 ± 11.31	62.29 ± 3.16*	↑101
I	41.82 ± 7.79	35.57 ± 9.07	↓15
IT	43.09 ± 5.80	40.00 ± 7.21	↓7
ITE	38.23 ± 6.95	69.73 ± 8.87*	↑82
IE	22.02 ± 11.78	59.37 ± 12.32*	↑170
IEP	23.28 ± 12.57	60.39 ± 11.77*	↑159
EAPI	40.23 ± 7.47	69.45 ± 6.29*	↑73

^*P < 0.05. The animals were submitted to maximal physical capacity test in the starting and at the final of experiment. In the case of E, IE, ITE, IEP, and EAPI groups, the test also was applied every 4 weeks from the initial week. The time was measured in minutes.

^*P < 0.05. Arrows indicate increase or decrease in exercise time in relation to the first week.
