| 摘要: | 目的：本研究藉由離心運動誘發肌肉損傷後，觀察不同時間 (5 分鐘、10 分鐘)的 30 Hz 按摩槍介入會如何影響肌肉恢復。方法：招募 7 名健康男性大學生，採重複測量法隨機分配至 5 分鐘按摩槍組、10 分鐘按摩槍組與控制組，每位研究對象均先進行等速離心運動：一組 15 次共 10 組、每秒 60 度的角速度、組間休息 60 秒，膝關節活動範圍為 0 度 (膝關節完全伸直) 到 90 度，藉此誘發肌肉損傷後立即進行恢復手法介入，分別在運前、後立即、介入後立即及後 1、2、3、7 天評估主觀肌肉痠痛 (muscle soreness, SOR)、肌肉張力變化 (張力、彈性及硬度)、膝關節活動範圍(range of motion, ROM)、垂直跳，以及最大自主收縮力量。所得資料將使用以重複量數變異數分析 (repeated measures ANOVA) 考驗三種不同恢復處理對各項評估指標在運動前、後立即、介入後立即及後 1、2、3、7 天的差異。
結果：一、運動後恢復介入的主觀痠痛在恢復進步率沒有達顯著差異 F (2, 12) = .372，p = .697，ηp2 = .58，但按摩組的恢復進步率皆大於控制組且存在大效果量 (.138 ≤ ηp2) 。
二、運動後恢復介入的關節活動度和垂直跳並沒有達顯著差異 (p > .05) 。
三、最大自主收縮力量在經過 10 分鐘按摩槍介入達顯著差異 (180.3 ± 52.5 vs 238.3 ± 48.5 N-M, p < .05)。四、張力 (Hz) 在實施按摩槍治療過後皆有顯著差異，且是 10 分鐘按摩組的恢復進步率最大；在彈性 (秒) 的部分股直肌和股內側肌恢復進步率在 5 分鐘按摩組進步幅度是最大的，而股外側肌則是在 10 分鐘按摩後彈性恢復較佳；硬度 (N / m) 的恢復進步率皆為 10 分鐘按摩組表現優於控制組與 5 分鐘按摩組。結論：本研究雖然因樣本數較少數據間無顯著差異，但就肌肉痠痛、肌肉張力變化、膝關節活動範圍、垂直跳，II以及最大自主收縮力量恢復進步率百分比，可得知 10 分鐘按摩槍治療在整體看來為最有效益的恢復介入，此結果可提供給運動治療相關專業人員、教練與選手。
Purpose: This study was conducted to observe how muscle recovery was affected by
30 Hz massage gun interventions of different durations (5 and 10 minutes) after muscle
damage induced by eccentric exercise. Methods: 7 healthy male college students were were
included in a controlled, randomized, and designed cross-over investigation with three
experimental conditions: 5-minute massage gun group, 10-minute massage gun group and
control group. Each research object was first subjected to isokinetic eccentric exercise: 10
sets of 15 repetitions at an angular velocity of 60 degrees per second, with 60 seconds of rest
between sets, and a range of motion of the knee from 0 degrees (knee fully extended) to 90
degrees. In this way, muscle damage was induced and recovery techniques were performed
immediately after the intervention, respectively before and after exercise. Subjective muscle
soreness (SOR), muscle tension changes (tension, flexibility, and stiffness), knee range of
motion (ROM), vertical jump, and maximum voluntary isometric contraction were assessed
before isokinetic eccentric exercise, immediately after isokinetic eccentric exercise,
immediately after intervention, and 1, 2, 3, and 7 days after intervention, respectively. The
data obtained will be analyzed using repeated measures ANOVA to test the differences
between the three recovery treatments for each of the evaluation indicators.. Results: 1.
There was no significant difference in the recovery rate of subjective soreness after exercise
IV
recovery intervention F (2, 12) = .372, p = .697, ηp2 = .58, but the recovery rate of the
massage group was greater than that of the control group and there is a large effect size (.138≤ ηp2).
2. There was no significant difference in range of motion and vertical jump after
recovery intervention (p > .05). 3. The maximum voluntary isometric contraction was
significantly different after 10 minutes of massage gun intervention (180.3 ± 52.5 vs 238.3
± 48.5 N-M, p < .05). 4. There was a significant difference in tension (Hz) after massage gun
treatment, and the recovery rate was the highest in the 10-minute massage group; in terms
of elasticity (seconds), the recovery rate of the rectus femoris and vastus medialis muscles
is higher than that of the 5-minute massage group, while the elasticity of lateral femoral
muscles recovered better after the 10-minute massage; the recovery rate of stiffness (N/m)
was better in the 10-minute massage group than in the control group and the 5-minute
massage group. Conclusion: Although there were no significant difference between the data
in this study due to the small sample size, it can be known that the recovery rate of the 10-
minute massage gun treatment was the most effective recovery intervention overall in terms
of muscle soreness, changes in muscle tension, range of motion of the knee joint, vertical
jump, and maximum voluntary isometric contraction. The results are available to sports
therapy professionals, coaches and athletes. |
