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.
          
          


    Eagan High School: Where Girls Sports Rule The Autumn
    Posted by John Millea(jmillea@mshsl.org)- Updated 8/22/2016 3:09:18 PM

    Eagan High School has been a haven for girls athletic success in recent fall seasons, and there are certainly lots of reasons for that. Committed coaches, talented and hard-working athletes, and a supportive community are always important in such matters.

    Here’s a quick summary of what has taken place at Eagan…

    --The volleyball team has long been one of the state’s strongest programs, winning six big-school state titles since 1997. The Wildcats won Class 3A state championships in 2013 and last season; the 2015 roster included no seniors so Eagan is ranked No. 1 and is a strong favorite to win another title this season.

    --In girls soccer, Eagan is the two-time defending state champion in Class 2A, compiling a record of 37-2 over those two seasons.

    --The girls tennis team finished fourth at the 2A state tournament last fall and Samantha Nichols, who is now a junior, placed fifth in singles. The team is ranked fourth as the 2016 season begins and Nichols is ranked seventh among 2A individuals.

    --In girls swimming, Eagan finished 10th at the 2A state meet a year ago, with the 200 freestyle relay team placing fifth at state.

    Eagan’s recent success hasn’t been exclusively a girls domain. The boys swimming and diving team, for example, won its first state championship in 2015, and the 2015 boys track team won two relay titles and Sam Zenner (who anchored both relays) was the 100-meter state champ.

    Here are some other points that may be important in trying to assess the climate for girls sports at Eagan: The activities director (Sandra Setter Larsen) is female, as is the principal (Polly Reikowski). Heck, even the superintendent (Jane Berenz) fits the bill.

    “Four years ago our head custodian was female, too,” said Setter Larson with a laugh. “We’ve just had a lot of success recently in some of our sports. Soccer and volleyball, for sure. Our boys track team has had success, girls track. We’ve just been very blessed lately. We’ve had a good few years, that’s for sure.”

    Girls soccer coach Bulut Ozturk led Lakeville North to three consecutive state tournament appearances before coming to Eagan in 2014. During a break at a recent practice, he said a top-down model is part of the school’s athletic success.

    “I think it really comes from the leadership, from our athletic department. Sandy has done an amazing job, and it also comes from our principal, our vice principals, everyone in that office. The entire building is completely supportive and they back the coaches, they give us the freedom, the flexibility and they’re here to support us in whatever we need, whatever it takes for the program to be successful.

    “For the coaches who work in this kind of environment, it makes our jobs so much easier. It’s stress-free, and I think that’s one reason you see so much success.”

    Eagan also has a tradition of strong support from the student body. The student section known as “The Pit” is a vocal, entertaining presence at many sporting events.

    “Our fans in the building had such a fun fall going to all these events,” Setter Larson said. “With tennis, our swimmers, soccer and volleyball there was just so much to do. It was crazy. It was probably a little more of a down year in cross-country in terms of the scoreboard, but they’ve had five years of state tournament entrants. It’s very, very fun for an A.D. to have that experience. That’s a lot of bonus stuff in our jobs. That’s not why we do what we do but it is exciting when it happens.”

    Volleyball coach Kathy Gillen, who was inducted into the Minnesota Volleyball Coaches Association Hall of Fame in 2014 and was named the Class 3A coach of the year in 2015, said a family atmosphere is important.

    “We had a lot of really good chemistry last year and it’s nice to have that back,” she said. “You can already feel that family feeling. It’s a fun group to be around. They work hard, they have fun. It’s a great atmosphere.”

    There’s a similar feeling on the 2016 girls soccer team, even though last year’s roster was laden with seniors and there are many holes to fill this year.

    “It’s definitely creating a culture right now,” said sophomore Megan Plaschko. “All of our girls sports are being successful and I think it’s making people excited and wanting to come out and see what it’s all about.”

    Senior Carly Czaplewski said, “I think the success we’ve had is bringing more girls out here. They want to be part of Eagan sports. It’s a fun thing to be in, it’s a great way to meet people. We have a good time out here.”
