Warm Temperatures, Stay Cool
Using the heat guidelines

The heat stress graph is designed to give an estimate of safe competition conditions in hot, humid conditions. It is most relevant for long-distance running and prolonged high-intensity events like Lacrosse, Soccer, Football, and Tennis. It should be applied to both practices and games.

Using a weather radio or local radio station or new free mobile apps*, record the air temperature and relative humidity data every hour during the event and plot it on the relative humidity vs. air temperature graph. On bright sunny days in the late spring and summer months a correction factor of up to 5 degrees Fahrenheit should be added to the air temperature from 10 AM to 4 PM. This should be plotted as a bar rather than a single point to give an estimate of maximum and minimum heat stress.

The decision to cancel or postpone an event should be made when the heat stress moves into the danger range. Although practice and competition can be continued in the lower ranges, coaches and athletes should be aware that hyperthermia and exertional heat stroke can still occur in these lower risk ranges. Track and Cross Country runners should stay out of the heat between events and stay well hydrated. A rest break should be provided in activities that require continuous exertion like Soccer and Tennis.

    Coaches Checklist:
  • Follow the Heat Index shown
  • Watch kids closely
  • Take lots of breaks
  • Make sure athletes are hydrated
  • Athletes who take antihistamines or beta blockers may be at a greater risk
  • Trust Kids . . . They know what their bodies can take.
  • Don't let peer pressure force kids to make decisions that may cause harm

  • Green Line: Regular practices/games with full practice gear can be conducted for conditions that plot to the left of the green line.
  • Red Line: Cancel all practices and games when the temperature and relative humidity plot to the right of the red line. Practices may be moved into air-conditioned spaces.
  • Between Red and Yellow Lines: Increase rest to work ratio with breaks every 20 minutes and all protective equipment should be removed to practice in shorts only when the temperature and relative humidity plot between the red and yellow lines.
  • Between Yellow and Green Lines: Increase rest to work ratio with breaks every 30 minutes and wear shorts with helmets and shoulder pads only when the temperature and relative humidity plot between the yellow and green lines.
  • Heat risk rises with increasing heat and relative humidity. Fluid breaks should be scheduled for all practices and increased as the heat stree rises.
  • Add 5 degress to temperature between 10 AM and 4 PM from mid May to mid September on bright, sunny days.
  • Practices should be modified to reflect the conditions for the safety of the athletes.
          
          


    Looking Back: Homecoming For A Former Shakopee Softball Star
    Posted by John Millea(jmillea@mshsl.org)- Updated 7/19/2016 2:23:40 AM

    With the 2015-16 MSHSL year at an end, let's take a look back at some of the stories from John's Journal. This story was posted on May 15.

    Neil Johnson has witnessed a lot of memorable events during his 41 years as the only head softball coach Shakopee High School has ever had. The Sabers have gone to the state tournament in three different decades – the 1970s, 1980s and most recently in 2011 – and Johnson has been in the Minnesota softball coaches association Hall of Fame since 1995.

    The 2011 season was special, and members of that team were invited back to be honored during a pregame ceremony prior to Friday night’s non-conference home game against New Prague. Seven 2011 Sabers were on hand. During the introductions, one of them walked out of the New Prague bench.

    Ashley Walker was a star on that 2011 Sabers team, and now – after graduating from Winona State in December -- she is in her first year as head coach at New Prague. Johnson, meanwhile, has been in charge of the Sabers since 1975 and Walker is the first former player to become a head softball coach.

    “It’s kind of a unique thing,” Johnson (pictured with Walker) said after the Sabers defeated the Trojans 7-6 in eight innings on Strikeout Cancer Night. “I’m just as proud as all get out.”

    Johnson isn’t the only connection Ashley has to the current Sabers. The top assistant coach is her father, Rob.

    Ashley is a physical education and health teacher who is working as a substitute this spring. She’s living at home, or as she put it, “I live in Shakopee with Coach Dad. This was like half a home game for me.”

    Ask Johnson about Ashley the high school player and his eyes light up.

    “She was one of the best players I’ve ever had in 41 years,” he said. “I still remember her game-winning home run in the bottom of the sixth inning against Mankato West to help us go to the state tournament. She came out in the seventh inning, when they had the potential tying run on third and winning run on second, and she struck the last batter out. She’s a heck of a competitor and she has been the real epitome of Shakopee softball. She’s quite a young lady.”

    Ashley was a star at Winona State. She finished her senior season with a pitching record of 21-5 while striking out 106 and walking 38 in 170 innings. At the plate, she set a school record with 23 doubles while batting .372. In her college career, she ranks fourth at Winona State in doubles (53), seventh in home runs (23), eighth in batting average (.362) and ninth in hits (231). She also has the fourth-most career pitching wins with 62 and is sixth all-time in innings pitched with 515.2. She also was only the third player in Winona State history to be named an academic all-American, graduating with a 3.87 GPA.

    She was named the New Prague softball coach last fall, and the announcement coincided with an important event in Shakopee.

    “I found out she got the job the day the school board named the complex after me,” Johnson said, referring to the Neil Johnson Softball Complex, a fantastically manicured facility with three varsity-level fields. “It was a big day.”

    Johnson, who was inducted into the Minnesota State High School Coaches Association Hall of Fame last fall, has had a positive impact on countless softball players as well as students (he retired from teaching in 2014 after 39 years in the classroom). Ashley Walker is among that group. Here’s her answer to this question: Why did you become a coach?

    “Honestly, it was probably because of (Johnson), how awesome he was and how he treated us,” she said. “He makes everybody feel special, and I know the impact he makes on the girls’ lives. I wanted to carry that on myself.”

    Friday night’s extra-inning loss ended a seven-game winning streak for New Prague (10-4) and gave Shakopee a record of 5-10. Damara Theis had two doubles and four runs-batted-in for the Sabers, Ashley Herold hit a two-run home run, and Cortney Hokanson (who had three hits) drove in the winning run with a single in the eighth inning. Emily Schmitz led New Prague with three hits, including a two-run homer.

    After the game ended, both teams put on Strikeout Cancer t-shirts and posed for a photo together. Coaches embraced.

    “It was really fun, it was awesome,” Ashley Walker said. “It was fun to coach against Coach Johnson and against my dad. I have lot of respect for them. I couldn’t respect anybody more.”

    I wouldn't mind a bit if the @Vikings displayed all football helmets in the new stadium, as @XcelEnergyCtr does w/ hockey jerseys.
