From: Effects of the Frequency and Duration of Cyclic Stress on the Mechanical Properties of Cultured Collagen Fascicles From the Rabbit Patellar Tendon J Biomech Eng. 2005;127(7): doi: / Figure Legend: Apparatus for the culture of collagen fascicles under cyclic load condition . Four fascicles can be set up in parallel in a culture bath. Four load cells are used to measure load applied to each fascicle. A linear actuator was used for the application of displacement, and the load is continuously monitored during culture.

There were no noticeable differences in the shape of the curves among the groups. The tangent modulus was calculated from the slope of each curve (linear regression) between 2% and 5% strain.

From: Effects of the Frequency and Duration of Cyclic Stress on the Mechanical Properties of Cultured Collagen Fascicles From the Rabbit Patellar Tendon J Biomech Eng. 2005;127(7): doi: / Figure Legend: Tangent modulus of collagen fascicles. A two-way ANOVA was used to assess statistical differences with respect to experimental groups and culture periods, followed by Fisher’s PLSD test for comparisons among groups at each period. A two-way ANOVA showed significant differences among groups. The moduli in the non-loaded, 1Hz-1h, and 1Hz-4h groups were significantly smaller compared with the control group both at 1 and 2weeks. The moduli in the 4Hz-1h group were significantly larger than those in the control, non-loaded, 1Hz-1h, and 1Hz-4h groups except for at 2weeks; there was no significant difference between the 4Hz-1h and control groups at 2weeks. There were no significant differences in the modulus among these three groups except for the 1Hz-4h group at 2weeks.

From: Effects of the Frequency and Duration of Cyclic Stress on the Mechanical Properties of Cultured Collagen Fascicles From the Rabbit Patellar Tendon J Biomech Eng. 2005;127(7): doi: / Figure Legend: Tensile strength of collagen fascicles. A two-way ANOVA was used to assess statistical differences with respect to experimental groups and culture periods, followed by Fisher’s PLSD test for comparisons among groups at each period. A two-way ANOVA showed significant differences among groups. The strength in the non-loaded, 1Hz-1h, and 1Hz-4h groups were significantly lower compared with the control group both at 1 and 2weeks. Although there was a significant difference in the strength between the 4Hz-1h and control groups at 1week, this difference disappeared at 2weeks.

From: Effects of the Frequency and Duration of Cyclic Stress on the Mechanical Properties of Cultured Collagen Fascicles From the Rabbit Patellar Tendon J Biomech Eng. 2005;127(7): doi: / Figure Legend: Strain at failure of collagen fascicles. A two-way ANOVA was used to assess statistical differences with respect to experimental groups and culture periods, followed by Fisher’s PLSD test for comparisons among groups at each period. A two-way ANOVA showed significant differences among groups. The strain at failure was significantly larger in the 1Hz-1h and 1Hz-4h groups than in the control group except for the 1Hz-1h group at 1week, whereas there were no significant differences in the strain between the 4Hz-1h and control groups both at 1 and 2weeks.
