| Summary: | Physical work intensity of athletes during practice and game competition is difficult to measure and is not frequently found in the literature. While information from the laboratory is available, field data on subjects actually performing their skills is far less frequent. One way physical work intensity is measured during practice and game competition is by using portable heart rate(HR) monitors. In the present experiment, portable heart rate monitors were used to measure the heart rates of baseball pitchers. Pitchers from three different levels of competition(high school, collegiate, professional) were measured: in the laboratory for V02max and maximum heart rate, and in the field for heart rate intensity(HRI) during practice and game conditions. HRI was calculated to be a ratio of mean working heart rate while pitching to maximum HR found during a treadmill test. Comparisons were made for HRI while pitching, between the levels of subjects(high school, collegiate, professional) and between conditions (practice, a game). Within the limitations of the experiment in this study, the following results were found: 1. During practice conditions, professional pitchers worked at a significantly higher intensity than the high school pitchers. 2. During game conditions pitchers at all three levels performed at high intensities that were not different from one another. 3. High school pitchers performed at higher intensities during game conditions than during practice conditions. 4. Collegiate and professional pitchers performed at equal intensities during practice and game conditions. While physical maturity was considered, the results were considered more a reflection of experience and exposure to quality instruction than of pure physiological differences. The question of what was at stake for the subjects in each group was also mentioned as a possible factor in the results. |
