Investigation of Intensity Levels During Video Classroom Exercise Sessions
Keywords:classroom exercise, video exercise, exercise intensity
AbstractClassroom Exercises for the Body and Brain was developed in the state of Georgia by the HealthMPowers organization to help classroom teachers provide structured physical activity for their elementary students in their classrooms. These brief video exercises were designed for students to participate at their desks as exercise breaks, as energy boosters, or for rainy day recess. Many of these exercise programs are designed with good intentions, but they have little objective data to support their claims. The purpose of this study was to investigate the intensity levels of 9- and 10-year-old students participating in a video classroom exercise program in a regular classroom setting. Twenty-five fourth grade students (10 females, 15 males) from one class participated in this study. Four DVD video exercise sessions ranging from 1 min 45 s to 2 min 30 s were investigated. Over 65% of students reached their target heart rate zone during all exercise videos except for the chair aerobic video. No significant relationships were found between peak exercise heart rate and other variables including waist circumference, body mass index, and responses to the Rating of Perceived Exertion (RPE) scale. Students and the teacher reported positive feelings toward the exercise video program.
