- Darryl Kile was scheduled to pitch
against the Chicago Cubs on Sunday evening. But late Friday or early
Saturday morning he died!
Darryl Kile was an athlete. He was an
All-Star pitcher for the St. Louis Cardinals. He was not supposed to
die of a heart attack. But at the young age of 33, fatty deposits had
already blocked the coronary arteries in his heart.
It is rare for someone as young as
Darryl Kile to have a heart attack; but heart disease is increasing
among Americans as young as 15.
But if heart problems are caught early,
a better diet and aerobic-exercise program can help.
- You are on a special committee
for the Babe Ruth League. Your committee has developed a test that will
be given to all young people who are trying out for a baseball or
softball team. The test involves jogging in place for two minutes.
- The only thing left to do is
to set the standard for heart-rate-recovery-after-exercise. In other
words, the League needs a cut-off number so that kids whose hearts are
too weak can be identified.
- Read Fundamentals - What is a pulse?, and Skills - Proposed Babe-Ruth-League Heart Test. Work together with a class of middle school students to
determine how quickly heart rates return to normal after moderate
Determine the average time for heart
rates to return to normal after exercise. Then, decide where to set the
- Officials from the Babe Ruth League want
to know the average time that it takes for heart rates to return to
normal after exercise and the cut-off number that you have selected. Be
sure to explain why you have selected that particular cut-off number.
Prepare a postcard addressed to the
Babe Ruth League:
- Steven M. Tellefsen, President/CEO
Babe Ruth League, Inc.
Howard St. at Camden St.
- Include your return address in the upper
left-hand corner. In the body of the postcard, state:
- average resting heart rate _______
average exercise heart rate _______
average return to normal time
recommended cut-off time _______ min
- Other Scenario-Based Investigations
