Fig. 1 Apparatus used for measuring circumferential isotonic and longitudinal isometric contractions of the canine latissimus dorsi muscle. The animal’s head is to the right. The Annals of Thoracic Surgery , DOI: ( /S (96) )

Fig. 2 Total and segmental perfusion of paired delayed and nondelayed muscle flaps, expressed as a percentage of preelevation muscle perfusion, 15 minutes after flap elevation. Numbers are expressed as mean ± standard error of the mean (n = 9). (∗Significant difference [p < 0.05] between delayed and nondelayed muscle flaps.) The Annals of Thoracic Surgery , DOI: ( /S (96) )
4
Fig. 3 Total and segmental perfusion of paired delayed and nondelayed muscle flaps, expressed as a percentage of preelevation muscle perfusion, 2 weeks after flap elevation. Numbers are expressed as mean ± standard error of the mean (n = 9). (∗Significant difference [p < 0.05] between delayed and nondelayed muscle flaps.) The Annals of Thoracic Surgery , DOI: ( /S (96) )

Fig. 4 Temporal trends in distal muscle perfusion. Muscle perfusion measurements were taken immediately before flap elevation and 15 minutes and 2 weeks after flap elevation. Numbers are expressed as mean ± standard error of the mean (n = 9). (∗Significant difference [p < 0.05] between paired delayed and nondelayed muscle flaps.) The Annals of Thoracic Surgery , DOI: ( /S (96) )

Fig. 5 Circumferential force generated by rhythmic and tetanic contractions in both the loaded and unloaded positions. Numbers are expressed as mean ± standard error of the mean (n = 9). (∗Significant difference [p < 0.05] between paired delayed and nondelayed muscle flaps.) The Annals of Thoracic Surgery , DOI: ( /S (96) )
7
Fig. 6 Longitudinal force generated by rhythmic and tetanic contractions (kp, force acting on a 1-kg mass at normal acceleration of gravity) in the loaded position. Numbers are expressed as mean ± standard error of the mean (n = 9). The Annals of Thoracic Surgery , DOI: ( /S (96) )
8
Fig. 7 Rhythmic fatigue rates (seconds) in paired delayed and nondelayed muscle for both circumferential (loaded and unloaded) and longitudinal contractions. Numbers are expressed as mean ± standard error of the mean (n = 9). (∗Significant difference [p < 0.05] between delayed and nondelayed muscle flaps.) The Annals of Thoracic Surgery , DOI: ( /S (96) )
