DEVICES FOR USE DURING PHYSICAL ACTIVITY

A garment to be positioned about one or more body portions of a person performing a physical activity comprises a garment region having a garment region elasticity and a training region having a training region elasticity, the garment region stretching a greater distance as the result of an applied force than the training region under the same applied force. The training region at least partially defines a tensioning system of a biofeedback device. The biofeedback device is configured to provide sensory cues (e.g., feedback forces) to the person performing a physical activity when the person's biomechanic position is sub-optimal, the sensory cues indicating to the person that their biomechanic position is sub-optimal and indicating to the person how to adjust their one or more body portions towards a more optimal biomechanic position. The garment may provide for training and help the person achieve optimal biomechanic motion.
