Test on Anti Gravity SystemTM Patented Technology in Backpacks
Effective in Reducing the Rate of Muscle Fatigue & Risk of Musculoskeletal Injuries
A study was conducted by Guangzhou Sport University on the patented technology Anti Gravity SystemTM (AGS) designed by FX Creations. The AGS patented technology is similar to a suspension system integrated into a backpack. In response to the motions that are generated, this design is springy. This design creates rebound in response to motion.
Based on the test conducted, the AGS technology results showed a slower rate of cervical back muscle fatigue, quicker muscle recovery, better stability and improved posture when compared to a traditional backpack without AGS technology. The test also concludes that under the appropriate walking pace, AGS technology can potentially reduce the risk of musculoskeletal injuries and muscle fatigue associated with carrying heavy backpack loads. The reason for this is because AGS backpack is able to compensate for the dynamic load.
How was Anti Gravity SystemTM tested?
Biomechanical and physiological measurements were taken from 12 subjects (19 +/- 1.8 years old) who did no strenuous exercise two days prior to the test and are in healthy conditions (no acute or chronic illness). Two trials were conducted two days apart from each other. One was the control group where the participants wore a backpack with no AGS technology. The second group was the test group where the participants wore a backpack with AGS technology. For each trial, the participants carried the same amount of weight (8-10% of their body weight) and walked on a treadmill at 4.5km/h for 30 minutes. The sEMG measurement of the neck extensor, trapezius muscle, latissimus dorsi, and erector spinae muscle were taken along with gait and kinematics analysis.
FX Creations recognized the problem associated with heavy backpacks and hence has been working towards a solution since 2014. At first an AGS shoulder strap was invented. The shoulder strap is made from a highly elastic material so that when the user walks, a springy motion occurs. Based on user feedback, the shoulder strap made the carrying load feel lighter. Over time FX Creations incorporated that suspension idea into their backpacks, hoping to alleviate the problem of heavy backpacks.
