GENERAL READINESS: Dressing for physical activity.

Wear comfortable clothing.

Dress in layers when outside.

WASH CLOTHES REGULARLY!!

Wear proper shoes.

Wear proper socks.

Warm-up & Cool Down

WARM-UP

Prepares body for activity

Enhances performance

Can prevent injuries

Usually includes heart and muscle…

Warm up

Heart = min of 2 min…max = several minutes.Trying to increase body temp.

Stretching S-L-O-W

SPORT SPECIFIC!

COOL DOWN

Recovery time for body.

Heart cool down can prevent dizziness or fainting.

Hard exercise = increased blood flow to muscles ( less to head)

Stretching actually redirects blood to heart. Again…s-l-o-w-l-y.
