Feret’s Diameter in the Posterior Digastric and the Temporalis. No significant main effects were found for age or exercise condition in the posterior digastric muscle Feret’s diameter, indicating age and exercise did not have an effect on fiber size in the posterior digastric. In the temporalis muscle the old exercise group had on average a smaller measure of Feret’s diameter than the old control group (p=0.001), young adult control group (p=0.0.025), and young adult exercise group (p=0.024) suggesting the exercise condition resulted in a reduced fiber cross sectional area in the old animal group.

Muscle Age × Condition Feret’s Diameter Standard Error
Temporalis Old Control 59.563 1.652
Old Exercise 51.242* 2.099
Young Adult Control 58.763 1.645
Young Adult Exercise 59.504 1.910
Posterior Digastric Old Control 39.434 1.31
Old Exercise 36.813 1.21
Young Adult Control 38.639 0.954
Young Adult Exercise 38.208 1.178

Feret’s diameter values were covaried by weight of the animal at the end of the study.
