Westgaard 學者在1988年提出長時間處於相同的姿勢下，會產生肌肉的疲勞。
亦或者是運動時人體活動引起之肌肉收縮力量暫時下降所產生的肌肉疲勞。
疲勞的產生幾乎無所不在，現代人過度忙碌，較少時間能好好放鬆自己，消除疲勞。
本研究設計了一套評估疲勞改善之系統，以提供使用者選擇有助於自己疲勞改善的方法。
本研究採用肌電圖(EMG)、肌動圖(MMG)、心率(HR)、心率變異度(HRV)等多個生理參數，
來評估、比較低週波電刺激器和遠紅外線照射器對肌肉疲勞改善程度。
實驗發現，經遠紅外線照射不僅能對自律神經產生影響，對局部性肌肉的疲勞改善亦有一
定的成效。低週波電刺激治療器則能有效改善肌肉疲勞，讓肌肉能在短時間內消除疲勞感。
本研究並加入類神經網路架構，準確地掌握肌肉疲勞的機率。

Dr. Westgaard presented that someone who stays the same posture for a long time may suffer from muscle fatigue. Also, when a person temporarily decrease the power of muscle contraction resulted from exercise might bring the fatigue to muscle. The generations of body fatigue are everywhere. Modern people are too busy to relax themselves or relieve the fatigue. This research designs a set of system to estimate the improvement of the fatigue and offer the users the right way to improve the fatigue to their own.
This research adopts several physiological parameters to estimate and compare the muscle fatigue by far infrared thermotherapy and T.E.N.S electrical stimulation like Electromyogram (EMG), Mechanomyography (MMG), Heart rate (HR), Heart rate variability (HRV), and so on. The experiment results show that the far infrared thermotherapy could not only affect the autonomic nervous system, but also have the effect to improve the partial muscle fatigue. T.E.N.S electrical stimulation could also effectively improve the muscle fatigue and eliminate the feeling of muscle fatigue in a short time. Besides, this research adds the neural network structure, so we can master the probability of muscle fatigue precisely.
