中文摘要 | 本研究的目的在於探討連續一週的密集離心訓練,對所完成的總作功、即時最大 肌力與關節活動範圍下降率的影響。本研究是以 12 名大專健康男性學生做為受試對象,平 均年齡為 19.2 ± 0.7 歲,身高 171.9 ± 5. 3 公分,體重 66.5 ± 5.1 公斤。 實驗 開始所有受試者須先接受一次肘關節活動範圍 (ROM) 和最大等長肌力 (MIF) 的測量;之後 ,在使用 Cybex 6000 將轉速設定在每秒 60 度,讓受試者做一回合 30 次的最大自主等速 離心收縮 (ECC),來誘發非慣用手的肱二頭肌產生延遲性肌肉酸痛 (DOMS)。 全部受試者須 連續 7 天,每天各接受一回合的離心訓練。 所有受試者在每天的離心訓練之前、後,均須 各接受一次 ROM 以及 MIF 的測量。結果:發現受試者在每天離心訓練所完成的總作功值、 即時肌力和 ROM 下降百分比,均達到顯著的差異水準 (F= 22.74; F=20.95; F=23.09,P <.01);總作功與 MIF 下降率之間成正相關 (r=.80,P<.01);即時的 ROM 下降率與總作功 之間也有相關存在 (r=.64,P<.05)。 結論:在 DOMS 的情形下,再連續做六天的離心訓練 時, 所完成的總作功僅達第一天離心訓練的 57-73%,而且在運動後即時的最大肌力和 ROM 下降率與剛完成的總作功成正比;這些資料可能可以做為教練在擬訂高強度離心肌力訓練初 期時之訓練負荷設定之參考。 也就是說, 在進行高強度離心肌力訓練的第一週時,建議第 1-4 天可先採用第 1 天練訓所完成的總作功量的 60% 強度,第 5-7 天再採用第 1 天總作 功量的 70% 強度來作訓練會比較恰當。 |
英文摘要 | This study was to investigate the effects of continuous eccentric exercise training on total work, maximal isometric force (MIF) and range of motion (ROM). Twelve healthy, active males (19.2 ± 0.7yrs, 171.9 ± 5.3cm, 66.5 ± 5.1 kg), served as subjects. The initial exercise (ECC1) was 3 × 10 reps of maximal voluntary isokinetic eccentric contraction (ECC) on the non-dominant elbow flexors with Cybex 6000 at a speed of 60 ° / sec. Subjects performed the same exercise for the following 6 days after ECC1. MIF and ROM were measured before and immediately after each eccentric exercise. There was a significant drop in total work through 7 exercises (F=22.74, P<.01), and the percentages of MIF and ROM decreased dramatically at the same time (F=20.95, P<.01; F=23.09,P<.01). The MIF and ROM decreased values were positively correlated with total work performed (r=0.80, P<.01; r=.64, P<.05). Conclusions:Continuous maximal eccentric exercise training during DOMS was only 57% to 73% of the initial total work. In addition, there was a direct positive correlation among the amount of total work, the percentages of strength and ROM decrement measured immediately after each exercise. Therefore, it may be appropriate to train at 60% of the pre-exercise maximal eccentric force during the first 4 days, but use 70% of the pre-exercise maximal eccentric force for days 5 to days 7. |
