The purpose of the study conducted by SFSU was to investigate the effects of a lateral sway bike in different fields of exercise science, including muscle activity (EMG), cardiorespiratory patterns, cycling mechanics, and motivational levels.
According to a study at SFSU, the Evo's sway function helped to more accurately simulate uphill cycling when compared to a stationary indoor cycle. The study found that participants trunk displacement was lower while using the Evo, meaning that the core was being utilized more in order to stabilize the body.
Standing Cycling Mechanics involves the arms pulling up and back during the power stroke of the corresponding leg while the arms push down and forward during the upstroke of the corresponding leg. These arm activities are coordinated with the leaning of the bicycle, so the upper body contributes with the positive power output.
The study at SFSU tested the muscle activity of the rectus abdominis, external oblique, erector spinae, and anterior superior iliac spine to find out the effectiveness of the sway function. The sway function of the Evo Fitness Bike significantly increases the use of the rectus abdominis.
