You would need data from a large number of people, best from a varied age and gender.

The pulse rates taken not watching television and watching an unexciting program serve as a control and comparison to eliminate the conjecture that watching any television causes pulse rate to increase. You would also have to be sure that each person is watching a sport that they consider exciting rather than one that you consider exciting, not everyone finds the same things exciting.
