Abstract: Systems and methods for using a lightweight training bag assembly and apparatus provide the punch-feel of common heavy, ceiling-mounted punching bags. Unwanted motion, sound, and other undesirable side-effects associated with existing punching bag designs are successfully avoided. Various embodiments accomplish this by isolating a supporting base from the impact of a punch by using a flexible shaft assembly that translates an angular motion of a shaft into a lateral motion.

Abstract: A training system based on mobile technology and kinematics of human motion characterizes, analyzes, and supplies feedback to a user based on the user's movements. The training system includes a garment having a sensor control module connected to multiple sensor nodes via electrically-conductive fabric running along parts portions of the garment. The sensor module/nodes can communicate through the conductive fabric. The sensor nodes acquire motion and/or physiologic readings that are wirelessly transmitted to a mobile computing device that runs an application that analyzes the data and provides visual (e.g., graphs, 3D avatar) and audio feedback (e.g., voice prompts). Vibration motors and LEDs/electroluminescent fabric in the garment also provide notifications and alerts. The triple layer of garment, conductive fabric, and sensor module/sensor node are sealed against contaminants, allowing the garment to be washable.
