研究目的：探討步行運動介入對電子製造業工廠輪班工作者與正常班工作者心率變化及睡眠品質的影響。研究方法：其工作性質分為正常班與輪班人員，受試者共10位，以穿戴式行動裝置及匹茲堡睡眠品質量表 （The Pittsburgh Sleep Quality Index, PSQI）為工具，將收集之資料以SPSS統計軟體分析，比較正常班及輪班者，走路步數及心率等變項在睡眠品質上的影響及差異。結果: 一、以28天平均步數來看，輪班組步數6946.4±2574.1步、正常班組步數5559.1± 2230.7步，兩組間達顯著差異， [t (10) = -7.711, p = <.001]。二、以平均心率：輪班組每分鐘75.6±8.7 bpm、正常班組每分鐘79.7±13.1 bpm，兩組間達顯著差異， [t (10) = 4.856, p = <.001]。三、以安靜心率來看，輪班組每分鐘53.9±5.7 bpm、正常班組每分鐘57.9 ± 14.3 bpm ，兩組間達顯著差異， [t (10) = 4.807, p = <.001]。四、各項步數指標，包括前1天、前7天、前14天及前28天平均步行數與與當日平均心率及與當日安靜心率呈現負相關。五、睡眠品質：從整體睡眠品質來看，輪班組分數 5.82 ± 2.99分、正常班組分數4.85 ± 2.30 分，兩組間無顯著差異 (p = .250)。上述結果顯示，心率確實與步行運動步數的多寡有相關，當行走步數越多，身體活動量相對會越多，平均心率會比較低，心肺功能會越好，比較兩組整體睡眠品質無顯著差異，在行走步數上輪班人員的步數大於正常班人員，身體活動量也就大於正常班，在平均心率及安靜心率比較結果輪班人員低於正常班人員。結論:輪班人員休假天數比上正常班人員多7天休假，而透過足夠的休假日以及更多的運動，可以達到接近與正常班者同樣品質的睡眠狀況，所以不管在正常班或輪班時皆要養成運動習慣，應是促進身心健康及有更好睡眠品質的有效方法。

SUMMARY
Research purpose:
To investigate the effects of walking on heart rate and sleep quality for shift workers and daily workers in electronic components factory.
Method：
Participants (n=10) were divided into two groups depending on their working schedule. Each participant received a wearable device to monitor heart rate and step counts, and sleeping behavior. All participant were required to fill out Pittsburgh Sleep Quality Index (PSQI) for evaluating their sleep quality. Statistic analyzed of student’s T-test and Pearson’s correlation was performed using SPSS 17.0.
Result:
1)There is significant difference [t (8) = -7.711, p = <.001] in 28-day average step counts between shift group (6946.4±2574.1) and daily group (5559.1± 2230.7); 2)There is significant difference [t (8) = 4.856, p = <.001] in average heart rate between shift group (75.6±8.7 bpm) and daily group (79.7±13.1 bpm); 3)There is significant difference [t (8) = 4.807, p = <.001] in resting heart rate between shift group (53.9±5.7 bpm) and daily group (57.9 ± 14.3 bpm); 4)Every step counts indicators are negative correlated to average heart rate and resting heart rate; 5)There is no significant difference (p = .250) in the report of PSQI scale between shift group (5.82 ± 2.99 points) and daily group (4.85 ± 2.30 points).
Conclusion:
Lower rest heart rate is associated with higher walking steps, which suggested an improved physical fitness. Shift workers have seven more holidays than daily workers. By having more break time and doing more exercise on holiday, shift workers show non-different sleep quality with daily workers. Physical activity participant can be an ameliorator for shift work caused challenge to sleep quality as well as health.
