Abstract

Heart rate (HR) monitoring during exercise represents a potentially useful strategy for teachers delivering physical education lessons. This study examined how projecting HR monitor data onto a screen acutely affected school students’ exercise intensity during a high-intensity interval training (HIIT) session. Twenty students (12.3 ± 0.9 years, male = 8, female = 12) from one primary school volunteered to participate. Using a randomised crossover design within a 4-week period, participants completed four sessions of HIIT with HR projection and four sessions of HIIT with no ability to view HR. During the HR projection condition all participants viewed their HR on a class screen in real-time, with a changing colour according to HR level. Target intensity was 90% of age-predicted maximum HR. Peak HR and time above 90% HR (RED) were collected in all sessions. Student focus groups and teacher interviews were conducted to gain perceptions around the effects of the projection. Peak HR ( p = 0.005, η2 effect size = 0.049) and RED ( p = 0.000, η2 effect size = 0.083) were significantly greater during the projected condition. Qualitative data indicated that projection improved student motivation to reach the target, and ignited competition amongst peers to work harder. Projecting HR data onto a screen can increase the acute exercise intensity of school students during HIIT. HR projection therefore represents a useful strategy for the delivery of exercise sessions with an emphasis on intensity, within physical education classes.
心率监测器投影对在校学生运动强度的急性影响
运动过程中的心率(HR)监测是教师开展体育课的一种潜在有用策略。本研究探讨了在高强度间歇训练(HIIT)课程中,将心率监测器数据投射到屏幕上对学生运动强度的影响。来自一所小学的 20 名学生(12.3 ± 0.9 岁,男生 = 8 人,女生 = 12 人)自愿参加了这项研究。在为期四周的时间里,参与者采用随机交叉设计,分别完成了四节带有心率投影的高强度间歇训练和四节无法查看心率的高强度间歇训练。在心率投影条件下,所有参与者都能在班级屏幕上实时查看自己的心率,并根据心率水平改变颜色。目标强度为年龄预测最大心率的 90%。所有课程都收集了峰值心率和超过 90% 心率的时间(RED)。为了了解学生对投影效果的看法,还进行了学生焦点小组和教师访谈。在投影条件下,峰值心率(p = 0.005,η2效应大小 = 0.049)和RED(p = 0.000,η2效应大小 = 0.083)显著增加。定性数据表明,投影提高了学生达到目标的积极性,并激发了同学之间更加努力的竞争。将心率数据投射到屏幕上可以提高在校学生在 HIIT 期间的急性运动强度。因此,心率投影是在体育课上开展强调强度的运动课程的有效策略。
