The constraint is fast, erratic movement — a child sprinting, a ball in play — so you lock the shutter and let everything else adapt. Shutter priority at 1/1000 freezes the action; f/4 at 70mm keeps enough depth to survive small focus errors while still lifting the subject off a busy background. Auto ISO copes with sun and cloud, and AF-C with human recognition and continuous-high drive lets you hold a burst as the subject moves toward you.
Watch out for a shutter that is fast enough but a focus system you have not set up to track. Use back-button focus so you can start tracking early and hold it through the action, and keep the subject inside the frame — recognition can only follow what it can see. Anticipate the peak moment and fire a hair before it, not after.
