Schools Continue to Manage the Heat

It certainly was not the MHSAA’s intent to spur the most historically frigid back-to-back winters the state has seen. Nor did the Association wish for one of the mildest summers in recent memory during 2014.
Seemingly, it’s just Mother Nature’s way of reading into MHSAA efforts for managing heat and humidity and acclimatizing student-athletes for warm-weather activities.
Since guidelines were put in place (recommended for regular-season sessions and required for postseason tournaments) before the 2013-14 school year, there have been relatively few days during which psychrometers have had to be implemented.
“The key is, we’ve got plans in place for when the climate returns to normal trends for return-to-school practices and contests in August and September, as well as early June events,” said MHSAA Executive Director Jack Roberts. “It is a bit ironic that there have been relatively few days since the guidelines were established that they’ve actually come into play.”
In a nutshell, the guidelines provide instruction for four ranges of heat index: below 95 degrees; 95-99 degrees; 99-104 degrees, and heat indexes above 104 degrees, with increasing precautions in place as heat indexes rise. An index above 104 calls for all activity to cease.
Certified athletic trainers Gretchen Mohney and James Lioy agree that recent requirements in heat and hydration guidelines are a step in the right direction and encourage that – when possible – an athletic trainer oversee the implementation. Simply taking a reading from just outside the AD’s office or at home does not simulate on-site conditions.
“This doesn’t take into account the radiant heat at the site, which can drastically affect the conditions that athlete plays in. It is essential that all parties involved in making decisions to play collaborate with one another,” Mohney said.
Heat-related deaths in athletics rank only behind cardiac disorders and head and neck injuries, but such fatalities might lead the way in frustration for families and communities of the victims. The reason? Heat-related illness is totally preventable.
Another source of mild frustration is the lack of recording within the state for those practice and game situations which warrant heat protocols.
When the Representative Council was formulating the Heat and Humidity Policy, it was also mindful of ways in which the MHSAA could assist schools in putting the plan into practice. Coaches, athletic directors and trainers needed a method to record information for athletic directors to view and for the MHSAA to track. The MHSAA developed interactive web pages on MHSAA.com which allow registered personnel to record weather conditions as practices and contests are taking place, using psychrometers.
Additionally, discounted Heat and Humidity Monitors and Precision Heat Index Instruments are offered to schools through a partnership between the MHSAA and School Health.
Yet, since the availability of such tools came to fruition two years back, fewer than 1,000 entries have been recorded, and many are multiple entries from the same schools.
Of the 772 entries, only 15 took place when the heat index was in excess of 104, while just 21 indicated an index of greater than 100. Cooler temperatures could be playing a factor in the overall number of participation, particularly in the northern areas of the state.
Nearly all of the responses came during fall practices, with a few isolated cases coming during the spring.
As Mohney pointed out, all resources must be properly used in concert with one another to achieve desired results.
Reminders of the tools available to schools are disseminated throughout the state each summer.
Van Valkenburg Returns to Madison to Continue Dad's Pole Vaulting Program

Larry Van Valkenburg had two passions in retirement – coaching high school track & field and racing motorcycles.
In September, only a few months after completing his 25th season as the pole vault coach at Adrian Madison, Van Valkenburg loaded up his motorcycle and headed to Harpster, Ohio, a tiny, unincorporated city of 160 residents in central Ohio.
“He loved racing motorcycles,” said his son, Trevor Van Valkenburg. “Seems like an odd hobby for someone in their 70s, but he loved it. He hadn’t done it for a couple of years and said he wanted to give it one more shot.”
While at a race in Harpster, Van Valkenburg, 78, was involved in a motorcycle crash, had trouble catching his breath and tragically died.
“He took a very hard fall,” Trevor said.
This spring, after months of deliberations, Trevor decided to end his nine-year run as track coach at nearby Onsted and take over for his father as an assistant at Madison. For all intents and purposes, he’s coming home.
“It really is like coming home,” Trevor said. “I have crazy Madison ties that go way back.”
Trevor was a big reason why his dad began coaching at Madison. He was a high school sophomore in the early 2000s when he switched from baseball to track.
“When Coach (Josh) Powers took over the program in 1999, Madison didn’t have pole vault,” Van Valkenburg said. “Most of the schools in the 1990s had gotten rid of it. As a sophomore, I said if you have pole vault, I’ll run track. That is how my dad got involved.”
Trevor knew his dad had some background in pole vault.
“He was a vaulter in high school,” he said. “He always told us he had the school record. He vaulted in the 1960s where he would land in a pit of saw dust. As a junior, he broke his arm vaulting. He had a scar he would show us from time to time. His proud accomplishment was he came back as a senior and set the school record.”
With Trevor a senior, the Van Valkenburgs were part of Madison’s run to a Michigan Interscholastic Track Coaches Association (MITCA) track & field team state championship.
“He ended up staying 25 years,” Trevor said, speaking of his dad. “He loved it.”
Pole vault is a tough event to learn – and teach.
“In my opinion, it’s probably the most complicated high school sport,” Trevor said. “There are so many variables, how long your pole is, what the wind rating is, the flex rating and you have to set up your steps. You can move the bar so you have to know where to put it. It’s almost impossible to do well without a good coach. There are too many things an outside person needs to watch and give you feedback on.
“I always tell the kids every time you focus on one thing in pole vault about 30 other things go wrong – and that’s fine. It’s a very complicated high school thing to do. If you don’t have a good coach, it’s really hard to be successful.”
Last year, Trevor’s son Noah was on the Trojans middle school track & field team and chose the pole vault as one of his events. His grandfather was able to coach him.
“I am thankful for that,” Trevor said.
Over the years, the elder Van Valkenburg coached numerous league, county and Regional champs. Trevor joined his high school friend, Kyle Cessna, at Onsted, first coaching the pole vault but later coaching distance runners and the Wildcats cross country team. Madison and Onsted were in the same league, the Lenawee County Athletic Association, for the last several years.
“Over the years my dad and I had plenty of good pole vault coaching and team battles,” Trevor said. “We were really competitive at first. Over time, that relaxed a little bit.”
Returning to Madison to coach was an emotional decision for Trevor.
“I’ve coached Onsted for nine seasons,” Van Valkenburg said. “It was kind of always in the back of my head that if my dad was ever done, I’ll go back to Madison. I knew he would hold on as long as he could. It didn’t end up the way we thought it would, but it finally happened and I’m back home.”
Another reason it is home is because his wife, Kathryn, has taught at Madison schools for more than 20 years. His younger son, Dominque, also attends Madison schools.
“When I’m here after school, my whole family is here,” he said. “My wife is in the building. My one son is getting out of elementary at 3:30, my other son is on the middle school track team.”
Larry Van Valkenburg was an ex-Marine who retired as an air traffic controller in 2011. His legacy will remain at Madison, mainly because he teamed with Powers and the rest of the coaching staff to form a powerhouse track & field program that won numerous league championships and made an impact at MHSAA Finals.
“Larry was a great coach,” Powers said. “Trevor is a lot like him. We are really happy he came back to coach.”
Trevor Van Valkenburg is the director of the Lenawee District Library, a system that has six branches and a bookmobile. They circulate more than 150,000 items a year. Each spring, he adjusts his schedule to allow for coaching. He feels at home at Madison – and the track & field athletes can take comfort knowing a Van Valkenburg is still coaching them.
“We’re pretty similar,” Trevor said. “I learned a lot of it from (my dad), so it makes sense we would be similar. We both are pretty laid-back people. We’re not going to scream in kids’ faces. I might be a little more drill-heavy instead of just practicing jumping over the bar. I learned everything I know from him.”
