“…The vertical joint reaction forces were highest in the low ramp positions except at the ankle where the forces were greater in the high ramp position but this difference across the ramps was not significant. Vertical joint reaction forces at the hip, knee, and ankle in the present study were much less than those measured during walking, running, and stair climbing [20][21][22][23][24]. The vertical joint reaction forces at the knee during the elliptical stride were comparable to cycling [25,26].…”

Introduction:The elliptical trainer, developed to simulate running while minimizing joint loads, elicits a unique lower extremity biomechanical response. The purpose of this study was to examine the angular kinematics, peak net joint moments, and peak joint powers at the hip, knee and ankle joints while exercising at three different ramp settings on the elliptical trainer exercise machine (Precor EFX).Methods: Twenty-six healthy individuals with no history of lower extremity injury and with previous experience exercising on an elliptical trainer volunteered for this study. Motion was captured with two cameras as subjects performed exercise at three ramp conditions. The pedal resistance was kept constant at the lowest setting. The pedals of the elliptical were fitted with three orthogonal load cells. Video and force data were synchronized and used to perform a 2D inverse dynamics analysis.Results: As the ramp inclination increased, subjects demonstrated greater amounts of ankle dorsiflexion, knee flexion, hip flexion and lesser degrees of plantar flexion and hip extension (p <.000). Mean peak moments at the ankle joint were not significantly different across the ramp settings, but peak knee extensor and hip flexor moments increased while knee flexor and hip extensor at the hip decreased (p <.000). As the ramp inclination increased, peak positive power at both the knee and hip significantly decreased and negative power decreased at the knee joint (p <.000), though the effect size for these changes was small. Conclusions:The hip and knee joints were observed as the primary sources of power during exercise on the elliptical trainer at the lowest resistance setting.

“…As odd-impact exercises involve typically reaction forces of no more than approximately five times body weight [34,35], they are not mechanically as demanding to the body as vertical high-impact loadings, which can produce peak reaction forces from approximately ten up to 20 times of body weight [16,36]. In essence, the softer, mechanically less demanding odd-impact exercises may suit much better for many common people than vigorous high-impact exercises, and thus, feasible exercise regimens may be build on the principles of odd-impact loading.…”

“…13 Given the substantial mechanical forces that occur during simple activities such as walking, 14,15 any construct intended to fill a cartilage defect should have the ability to carry mechanical loads similar to the native tissue and to elicit a beneficial host response. To achieve these goals we developed a nonbiodegradable porous hydrogel (polyvinyl alcohol [PVA]) scaffold, the composition of which is stable over time and whose mechanical properties can be varied by changing the PVA polymer content.…”

Scaffold-cartilage integration is critical for the clinical success of a scaffold used for the repair of a focal cartilage defect. In this study, a macroporous polyvinyl alcohol (PVA) scaffold was found to facilitate chondrocyte infiltration and interfacial matrix formation in a juvenile bovine in vitro cartilage defect model. These results were found to depend on the press-fit between the scaffold and the cartilage, pretreatment of the cartilage with collagenase prior to scaffold insertion, and chondrocyte preseeding of the scaffold. Infiltrated and preseeded chondrocytes in the scaffold survived for 6 weeks in culture and resulted in sufficient matrix at the interface to significantly increase the interface shear strength 30-fold that compared favorably with the interface shear strength of cartilage-cartilage constructs. The ability of this macroporous PVA scaffold to form a stable interface with articular cartilage demonstrates the potential use of this scaffold design for focal cartilage defect repair.
