It has often been said that wrestling is the toughest and most grueling six minutes in all of sports. It is a sport that requires great dedication, discipline and conditioning from those kids that step onto the mat.

One of the most important parts of the high school wrestling program in Michigan is the weight monitoring program. Prior to the season, every wrestler undergoes a body composition test where the body fat percentage of each student is determined – and based on that data, a minimum weight and weight class is established for every participant.

This data provides a safe and healthy plan for kids that wish to drop weight and move down to a lower weight class as a wrestler can never lose more than 1.5 percent of their body weight in a given week. This program has made wrestling a safer and healthier sport for every single wrestler in the state of Michigan.

Be the Referee: Volleyball Libero Uniforms

Be The Referee is a series of short messages designed to help educate people on the rules of different sports, to help them better understand the art of officiating, and to recruit officials.

Below is this week's segment – Volleyball Libero Uniforms - Listen

Before the match begins, a volleyball team takes the court wearing super-stylish, brand-new jerseys. The libero is in a bright neon top, but two other teammates also have the same neon sleeves.

At first glance, it looks like multiple liberos are on the floor. As the referee, you must check carefully: Under current NFHS uniform rules, the libero’s jersey must clearly contrast from all other teammates in color, design, and trim.

Accessories like sleeves or leggings are permitted, but they cannot confuse the identification of the libero. In this case, because the libero’s jersey color is the same as teammates’ sleeve color, the contrast is not sufficient, and the coach must correct it before play begins.

This ensures quick identification for substitutions, scoring, and libero actions.
