which type of balance is key to running?\no level\no static\no bosu\no dynamic

Brief Explanations:

Running is a dynamic activity. Dynamic balance refers to the ability to maintain an upright position while moving. Level balance is a more general - term not specific to movement. Static balance is about maintaining a position without movement. Bosu is a type of equipment, not a type of balance. So dynamic balance is crucial for running as the body is in motion.

Answer:

dynamic
