LLLT

在4週的非訓練對照期之前和之後，從20名男性志願者的股直肌（RF）和股外側肌（VL）獲取超聲圖像，並且在等速離心訓練4,8和12週後進行另外的評估。。 結果：RF和VL在前4個訓練週內肌肉結構發生顯著變化，整個乾預過程中的適應性反應相似。 肌肉厚度增加約7-10％，束長度增加17-19％，並且pennation角度不變。 結論：由於偏心訓練增加的肌肉厚度與增加的束長度有關，而不是與pennation角度的變化有關。 Ultrasonography images were taken from rectus femoris (RF) and vastus lateralis (VL) of 20 male volunteers before and after a non‐training control period of 4 weeks, and additional evaluations were performed after 4, 8, and 12 weeks of isokinetic eccentric training. Results: RF and VL had significant changes in muscle architecture within the first 4 training weeks, and the adaptive response throughout the intervention was similar. Muscle thickness increased by around 7–10%, fascicle length increased 17–19%, and pennation angle was unchanged. Conclusions: Increased muscle thickness due to eccentric training was related to increased fascicle length and not to pennation angle changes. Baroni, Bruno Manfredini, et al.

本研究旨在探討LLLT在老年女性疲勞過程中的作用。 這些發現開啟了臨床窗口，使用LLLT對老年人進行力量訓練計劃時對抗肌肉減少症。 在疲勞方案之前立即在股直肌上遞送活性LLLT（808nm波長，100mW，能量7J）或相同的安慰劑LLLT。 受試者進行疲勞方案，該方案包括在60秒內以相當於75％的1-MR（最大重複）的負荷進行的膝關節屈曲 - 伸展的自發等張收縮。 從占優勢的下肢的股直肌記錄表面肌電圖（SEMG）信號以評估外周易疲勞性。 在活躍的LLLT後，受試者表現出顯著更高的重複次數（p = 0.047）。 在這項研究中，LLLT在增加膝關節屈伸運動期間的平均重複次數方面是有效的，儘管結果沒有表現出延遲疲勞。 the present study aimed to investigate the effects of  LLLT  during fatigue in elderly  women.
