Abstract

In an effort to make future curricular choices, the primary purpose of this study was to investigate the influence of participation in various activities on 5th grade students' heart rates. It was hypothesized that different activities would influence students' mean heart rates and time in target heart rate zone (THRZ) differently. Heart rate measurements were obtained through the use of Polar E600 heart rate monitors (HRM) during the 2006-2007 school year at Grundy Center, Iowa Elementary School. The data from the heart rate monitors were downloaded into Polar PE Manager Software to gather necessary information for this study. Subjects of this study consisted of forty-three 5th grade students (24 boys, 19 girls) ages 10-11. All 43 subjects (100%) were identified as Caucasian. Each class period, students were given the goal of achieving an average heart rate of 140 bpm and at 20 minutes in and above the THRZ, which was set at 125 to 190 beats per minute (bpm) according to the heart rate max formula (60-90%). After analyzing the results, each of the nine activities met the curriculum targets of average heart rate and time in THRZ. Each activity also succeeded in meeting Healthy People 2010 objective 22-10 (50% of class time in MVPA; USDHHS, 2000). The overall mean heart rate and percentage of class time in THRZ were 148.2 bpm and 69.3%, respectively. In regards to mean heart rate, statistically significant differences were found between sex (P < .05), activity (P < .05), and between activities and sex (P < .05). Thus, different activities caused differences in heart rate for both boys and girls. In addition, in at least some of the games, each sex responded differently to the type of game played. In regards to time in THRZ, results showed significant differences among individuals (P < .05) and activities (P < .05). Interestingly, boys and girls both averaged about the same amount of time in THRZ, whereas boys had a significantly higher mean heart rate. Therefore, while both sexes were exercising for similar amounts of time within the THRZ, the boys were exercising at a higher intensity.
