Paper Details

To determine which muscles need to be subjected to a conditioning program in order to improve one's performance on the flat serve used in tennis, a study was conducted by the Department of Health, Physical Education and Recreation at the Virginia Polytechnic Institute and State University. Five different were tested on each of 3 subjects, and the experiment was carried out 3 times for each treatment combination. The electromyographic data, recorded during the serve, are presented here. Use a 0.01 level of significance to test the hypothesis that
(a) Different subjects have equal electromyographic measurements:
(b) Different muscles have no effect on electromyographic measurements;
(c) Subjects and types of muscle do notinteract.
