Abstract:

Bodyweight exercises, often associated with calisthenics, is a form of exercise that omits the use of machines and weighted equipment. As certain population groups are unable to engage in physical activity due to elevated risk of injury, reduced motor control and limited strength, I sought to investigate the possible use of bodyweight exercise as an alternative method for targeting key body segments of interest. In this study, I hypothesized that common bodyweight postures and movement, that have shown evidence of targeting muscle groups of wide significance, would have reduced forces applied to joints, lower compression and shear stress, and a decreased risk than that of normally done weight-assisted exercises. Using a 3DSSPP software, models of male and female figures were created in five positions that carried out analysis of the joint moments, spinal forces and other analysis measurements. These biomechanical analyses found that a larger segment of the population could implement these postures with minimal risk. A REBA analysis and an Energy Expenditure Prediction Program was carried out on the same postures, which evaluated the state of the body parts at certain positions while working and determined appropriate rest time given the activity carried out, respectively. The results from these demonstrated a low to negligible level of risk for the various activities and rest times that are comparable to normal activity.
