Tibial Biomechanics and Adaptive Response to Mechanical Stimuli in the Green Iguana.

ABSTRACT: Mechanical loading models are used to study adaptive skeletal mechanobiology mechanisms. However, most studies have used mammal models, leaving a knowledge gap regarding how these mechanisms differ among vertebrate groups. To address this gap, we evaluated the in vivo bone strain environment of the left tibia in green iguanas during locomotion, axial compressive loading, and with finite element analysis. Our study involved examining male green iguanas (n = 7) over a range of speeds (0.45-1.34 m/s) and axial load magnitudes (-25 to -100 N) to determine peak strains. Bone strains were measured using single-element strain gauges and rosette strain gauges, surgically attached to the tibial anterior, posterior, and medial surfaces. At a speed of 1.34 m/s, peak strains ± standard d
