Animal	Body Weight, g	EDL	Soleus	EDL	Soleus	EDL	Soleus	EDL	Soleus
WT	35.9 ± 1.3 (8)	10.7 ± 0.3 (9)	10.5 ± 0.2 (9)	0.30 ± 0.01	0.29 ± 0.01	11.6 ± 0.4	12.0 ± 0.3	0.88 ± 0.04	0.83 ± 0.03
Tg+	28.5 ± 0.6* (7)	9.3 ± 0.3† (7)	9.3 ± 0.5† (7)	0.31 ± 0.01	0.32 ± 0.02	10.4 ± 0.3	10.1 ± 0.2	0.84 ± 0.05	0.87 ± 0.05

Values are means ± SE; number in parenthesis are the number of animals analyzed (for body wt) or number of muscles analyzed (for muscle wt). L₀, muscle optimal length; EDL, extensor digitorum longus; WT, wild type; Tg⁺, transgenic mouse model that overexpresses TNF-α in the lung.

^*P < 0.05 vs. WT, Student's t-test;

^†P < 0.05 vs. WT, one-way ANOVA.
