Below is this week's segment – Track & Field Exchange Zones - Listen

Let’s work in an exchange zone today – and see how much we know about this area during relay races at track & field events.

First: Exchange zones are now 30 meters in length. Previously, they were 20 meters with a 10-meter acceleration zone. But now, it’s just one 30-meter area. Runners must start inside the zone.

Now, what happens if the baton is dropped during an exchange? There are a couple of outcomes:

► If the baton is passed or dropped outside of the exchange zone – that relay team is disqualified.

► If the baton is dropped inside the zone, the runner can pick it up and re-join the race.

► If it’s dropped inside the zone but rolls out of the zone, either runner can retrieve it, return to the exchange zone and then restart his or her race – provided they don’t interfere with an opponent.

Be the Referee: Basketball Measurements

Below is this week's segment – Basketball Measurements - Listen

If you’ve seen the movie “Hoosiers,” you know that a basketball rim is 10 feet above the ground. That’s the same if you are in the gym at Beaver Island High School or at Little Caesars Arena. But what are the other court dimensions?

To start – courts are typically 84 feet long but can be up to 94 feet long. They are 50 feet wide.

The free throw line is 15 feet from the face of the backboard and the high school 3-point line is 19 feet, 9 inches from the basket.

Each hoop is a circle, 18 inches in diameter.

The boys play with a basketball 29½ inches in circumference, the girls with one 28½ inches in circumference.

And believe it or not, two girls balls will go through a standard rim at the same time.
