Table 3.

Tension-time indexes for either static contraction or passive stretch in in sham+Sed, sham+ExT, CHF+Sed, and CHF+ExT rats

	TTI, kg×s
Group	Contraction	Low stretch	High stretch
Sham+Sed	15.9 ± 1.3 (37)	7.0 ± 1.0 (18)	16.2 ± 1.3 (18)
Sham+ExT	16.2 ± 1.2 (35)	6.9 ± 1.0 (17)	16.3 ± 1.3 (17)
CHF+Sed	15.7 ± 1.3 (37)	7.0 ± 1.1 (23)	16.2 ± 1.2 (23)
CHF+ExT	15.7 ± 1.2 (38)	6.8 ± 1.0 (22)	16.4 ± 1.2 (22)

Values are means ± SE; numbers in the bracket represent the number of tested fibers. TTI, tension-time index. There were no significant differences (P > 0.05) in TTI in all 4 groups.
