what is the aerobic endurance
the ability of the cardio-respiratory system to work efficiency supplying nutrients and oxygen to working muscles during sustained physical activity
what is speed

what is coordination
the smooth flow of movement needed to perform a motor task efficiently and accurately
what is power
the product of strength and speed. expressed as the work done in a unit of time

what are the 3 types of speed
accelerate speed, pure speed, speed endurance
what are the two types of balance
