中文摘要 | 本研究目的,在於探討短期動、靜態處理對肌肉損傷恢復速度的影響。以一群大學健康男性學生 (N=37) 做為研究對象,以隨機方式將其分派至:動態 (n=13)、靜態 (n=12) 和控制等組 (n=12) 中。在實驗第1天,讓所有受試者非慣用手的肱二頭肌做一回合50次最大強度的離心收縮 (ECC),以引起明顯的肌肉損傷。在ECC後,靜態組立即將其非慣用手(肘關節彎曲90°)接受打石膏固定休息四天;動態組則在ECC後第0-4天時,各分別接受一回合50次手持5磅重的啞鈴進行向心收縮運動。等長肌力(MIF)、關節活動範圍和上臂圍安排在ECC前和後第4-10天(每間隔24小時)測量一次;肌肉酸痛安排在ECC前和後第4-10天測量一次;血液肌酸激酶 (CK) 值則安排在ECC前和後第1-10天測驗一次。結果發現不同三組在ECC後,所有依變項均產生顯著的變化(p<.05);其中靜態和動態組在MIF的恢復速率均比控制組來得快 (p<.05),靜態組在ECC後的CK值比控制組來得低 (p<.05),其他依變項則無組別上的差異 (p>.05)。結論:(一)讓受試者進行ECC後,立即給予連續四天的動態處理,可加速肌力的恢復速率;(二)若是讓損傷肌肉接受連續四天的靜態休息,則對肌力恢復、CIR和CK的修復情形較有幫助。因此,本研究的資料可提供給教練在督促選手或一般大眾在引起肌肉損傷時之參考。 |
英文摘要 | The purpose of the present study was to examine the effect of additional and reduced activities after eccentric exercise on the recovery of muscle damage markers. Thirty-seven college-age males were randomly assigned to active recovery (AR; n=13), immobilization (IM, n=12) and control (CON; n=12) groups. Participants performed a bout of 50 maximal eccentric contractions of the elbow flexors (ECC) using a dumbbell that was set at 100% of the pre-exercise maximal isometric force (MIF) level. Immediately after ECC, the IM participants had their arm immobilized in a cast and secured in a sling at 90 for 4 consecutive days of this study. Immediately after ECC, at 1, 2, 3, and 4 days after ECC, the AR participants performed a daily exercise regimen of 50 biceps curls with a 5 lb dumbbell. The CON participants had no restriction of their arm activity. MIF active range of motion (ROM), upper arm circumference (CIR), and muscle soreness were measured for 2 consecutive days pre-ECC (baseline), immediately after ECC, and at 24 hour intervals for 7 consecutive days (at 4 to 10 days after ECC) after the 4-day treatment period. Plasma CK activity was assessed before and for 10 consecutive days after ECC for all groups. There were significant changes (p<.05) in all criterion measures (i.e., MIF ROM, CIR, soreness, and CK) after ECC for all groups. The pattern of recovery in MIF was enhanced (p<.05) by both AR and IM when compared to CON, whereas recovery from muscle soreness was not significantly improved by IM and AR (p>.05). Moreover there was a significant increase in CK after ECC for all groups (p<.05). Although there was not a significant difference (p>.05) following ECC between AR and CON, the IM group was significantly lower (p<.05) in CK during and after treatment periods following ECC than CON These data suggest that active recovery may had a positive effect on the recovery of MIF whereas immobilization may had a positive effect on the recovery of MIF CIR, and CK. Therefore, this finding may provide some useful information for the general public and athletes when muscle damage is obvious. |
