Athletes: Prepare to Beat the Heat

August 4, 2014

Despite unseasonably cool temperatures this summer in Michigan, high school athletes should prepare for the heat that usually accompanies August and the beginning of Michigan High School Athletic Association fall practices as they kick off next week.

Each year, the MHSAA provides information to its member schools to help them prepare for hot weather practice and game conditions in the late summer and early fall. Football practice can begin August 11, followed by first practices for all other fall sports August 13.

The topic of heat-related injuries receives a lot of attention at this time of year, especially when deaths at the professional, collegiate and interscholastic levels of sport occur, and especially since they are preventable in most cases with the proper precautions. In football, data from the National Federation of State High School Associations shows that nationally 41 high school players died from heat stroke between 1995 and 2013.

Many MHSAA schools this fall are expected to again follow the MHSAA’s Model Policy for Managing Heat & Humidity that directs schools to monitor heat index prior to and during activity and recommends actions based on those readings.

Also this school year, for the first time, the MHSAA is requiring all assistant and subvarsity coaches at the high school level to complete the same rules and risk minimization meeting requirement as high school varsity head coaches, or, in the alternative, one of several online courses designated for this purpose on MHSAA.com.

“It’s not an accident that causes severe heat illness and death. It’s a lack of attention to what should’ve been taking place, a lack of preparation,” said John E. “Jack” Roberts, executive director of the MHSAA. “We’re trying to communicate to our constituents that if we make the precautions that we should, plan as we should, we will have none of these tragedies in school sports.”

The MHSAA Representative Council adopted in 2013 the Model Policy for Managing Heat & Humidity that, while not mandated for member schools, has been adopted by many at the local level. The plan directs schools to begin monitoring the heat index at the activity site once the air temperature reaches 80 degrees and provides recommendations when the heat index reaches certain points, including ceasing activities when it rises above 104 degrees.

The model policy is outlined in a number of places, including the publication Heat Ways, which is available for download from the MHSAA Website. Heat Ways not only provides the model policy, but addresses the need for proper acclimatization in hot weather.

Heat, hydration and acclimatization also are again focuses of the MHSAA’s required preseason rules meetings for coaches and officials. The online presentation discusses the need for good hydration in sports, regardless of the activity or time of year.

The Health & Safety Resources page of the MHSAA Website has a number of links to different publications and information and a free online presentation from the National Federation of State High School Associations. Visit MHSAA.com, click on “Schools” and then on “Health & Safety Resources” to find the information.

Roberts said the first days of formal practices in hot weather should be more for heat acclimatization than the conditioning of athletes, and that practices in such conditions need planning to become longer and more strenuous over a gradual progression of time.

He added schools also must consider moving practices to different times of day, different locations, or change practice plans to include different activities depending on the conditions. 

“I think all schools need to prepare themselves in these ways,” Roberts said. “They need to educate participants, parents and coaches about proper hydration and the dangers of practicing and competing when the heat and humidity are too high.” 

Niles' Arnold Remembered as Teacher & Leader, 'Doing Exactly What He was Meant To Do'

NILES – Throughout his 22-year career coaching varsity girls basketball at Niles High School, Jim Arnold required one thing from his players.

Southwest CorridorJust have fun. 

"Jim always stressed to his players that the one thing he wanted them to do when on the floor was to just have fun playing the game," said George Brawley, who served 15 seasons as one of Arnold's assistant coaches at various levels.

Arnold, 81, died Dec. 9 following an extended illness.

But throughout his career, Arnold's teams did much more than just enjoy themselves. The Benton Harbor native built a highly-successful program at Niles, where he achieved an overall win-loss record of 360-139 from 1986-2008, with 19 winning seasons. Under Arnold's watch, the Vikings captured seven conference titles, 10 District championships – including nine straight from 1997-2005 – and five Regional crowns.

Among Arnold's other accomplishments were being named Class B Coach of The Year by The Associated Press in 1998 and receiving honorable mention in 1997, along with selection by the Basketball Coaches Association of Michigan as Region 5 Coach of the Year in 2002 and 2004. He was also named conference Coach of the Year seven times and received the Herb Quade Memorial Sportsmanship Award for the 2002-2003 season.

Arnold also coached Niles to back-to-back District championships in softball in 1993 and 1994.

As young athlete himself, Arnold excelled on the baseball diamond. A successful player while at Benton Harbor, he also played on Twin City American Legion teams and was known as a team captain and a coach on the field. Arnold later had an invitation to try out at the professional level with the Baltimore Orioles, but an injury ended his pursuit of that dream.

Arnold later played third base for Bargain Center, a slow-pitch softball team that won a regional championship and went on to play in the national title game in St. Louis, Mo.

Arnold signals for a timeout. His daughters Sonya and Allison were among the athletes that Arnold mentored during his coaching career. Sonya (Martinez), his oldest daughter, played for her father in eighth grade.

"He made the game fun, and you wanted to do your best because you didn't want to disappoint him. He poured his heart into each and every practice and game because preparation mattered to him. He demanded excellence, and every player became better because of his coaching ability," said Martinez, a 1986 Niles graduate.

Allison (Clay) his youngest daughter, played on the 1990 Niles varsity squad that finished 25-1, winning conference, District and Regional titles. She is a 1991 graduate.

"It was awesome playing for my dad. Some of my best memories in my life were during that time,” Clay said. “He had high standards and inspired others to be the best version of themselves. He put his heart and soul into what he did, and I had a front-row seat to that."

Linda Arnold has fond memories as a coach's wife.

"I loved watching my husband coach because of the joy it brought him. His passion, intensity and the love he had for his players was genuine,” she said. “It was more than a game. It was more about developing players in the area of discipline, teamwork and giving your all. Even in the busiest part of the season, he always made me feel like a priority. I didn't just watch a coach. I watched a man doing exactly what he was meant to do.

"My husband coached with passion, but he loved his family with intention. My girls would go to his practices and we all attended his games, and we had the team over for team dinners. His players were a part of our extended family. He made sure we felt a part. He was the best coach in the world, and he was mine."

Jim Arnold was highly respected by his coaching peers. He was kind and treated everyone with dignity. The community of Niles knew what he stood for and they knew his standards were high. He was admired for his preparation and understanding of the game as well as his commitment to doing things the right way. He was strict but fair and treated everyone the same, whether you were the star player or last one off the bench, Martinez explained.

"Developing his players' character was far more important to him than winning," she said. "Dad lived what he taught. He modeled humility, hard work and lived a life of integrity. He made people better by being a part of their lives."

When Jim Arnold first began his junior high teaching career in Niles, he also coached the boys junior high basketball team. There were no girls basketball teams at the time, so a girl tried out for the boys team. She was good enough to make the team, so Arnold kept her. The following school year, the principal asked Arnold to organize a girls team – and the rest was history.

Former Niles varsity girls basketball coach Jessica Johnson, a teammate of Clay’s, recalls the experience of playing for Coach Arnold.

He would instill confidence in you while still holding you accountable," said Johnson, now an assistant women’s basketball coach at Southwestern Michigan College.

Johnson recalls Arnold's use of comic strips as a teaching tool to help his players improve upon their mistakes.

"If you had a game where you didn't shoot very well or took questionable shots, he would place pictures of bricks in the gym the day following the game," Johnson said.

"Coach Arnold went out of his way to build that relationship and trust with his players. He gave us lessons that extended way beyond the court that made us better people."

Mark Haase, a Niles alumnus and the current Vikings head varsity boys basketball coach, also had the privilege of playing for Arnold.

"I played freshman basketball for Coach Arnold. It was one of the most disciplined and well-conditioned teams I ever played on. He ran a tight ship, but it was done out of love and concern for his players. He has a great family and is a Niles legend," Haase said.

Niles athletic director Matt Brawley referred to Arnold as an amazing teacher, coach and individual in the school and community.

"Coach Arnold would never ask you to do anything he wouldn't do. He was very structured and expected a lot out of his players, and he got results without excuses,” Brawley said. “He was a true leader of Niles athletics. He was an unbelievably kind and humble individual.”
