摘要
目的:研制一种智慧健身教练系统,让使用者可以随时随地享受教练服务,达到科学健身效果。方法:通过实验收集17位自愿者的哈佛登阶(HST)与脚踏车数据,建立不同心肺耐力等级人群(状况分布为不好1人、稍差3人、普通3人、尚好3人、很好7人)运动强度(脚踏车转速)与心跳模型,实现通过目标心跳推算运动强度;并通过理论推导构建音乐速度与运动强度模型,实现以调节音乐速度来控制运动强度;最终结合穿戴式设备、移动智能平台以及Web技术,设计智慧健身教练系统。结果:各人群选择自身对应的运动心跳模型,在不同运动强度下心跳预测效果优于通用模型预测。测试者使用本系统参加实际健身时,各阶段的心跳都被很好地控制在预先设定的目标区域内。结论:本文研制的教练系统可以有效地帮助使用者达到科学健身的效果。
Objective： A smart coach system is designed to let users freely enjoy coaching services and scientifi cally achieve fi tness. Methods： To establish the models which were used to calculate exercise intensity through target heart rate, the data of Harvard-step-test and bicycle experiments of 17 volunteers were collected and specifi c sport heart-rate models were established for different group（separated into five levels base on cardiorespiratory endurance, 1 in bad level, 3 in less-ordinary level, 3 in ordinary level, 3 in good level, 7 in extremely good level）. The Music-sport model also has been built by theoretical derivation, to achieve exercise intensity control by adjusting the music tempo. Finally, we designed a smart coach system, that combined wearable devices, mobile intelligence platform and web technology. Results： The specifi c sport heart-rate model was more effective in calculating exercise intensity, through target heart rate, than the average sport heart-rate model. In practical verifi cation, subject heart rate was well controlled within the target scale among each phrase. Conclusion： This coach system can effectively help users achieve scientifi c fi tness results.
