| 摘要: | 目的：探討高加壓 (1.7倍收縮壓 ) 搭配低阻力 ( 30% 1RM ) 運動對肌肉生長激素、肌肉發炎指標與運動表現的影響。方法：招募14名男性角力隊選手 ( 年齡：21 ± 1.2歲，身高：170.7 ± 5.5公分，體重：73.7 ± 14.8公斤 )，進行3週高加壓 ＋ 低阻力 ( HOLR, 1.7 SBP ＋ 30% 1RM ) 運動，以斜坐推蹬方式進行雙腿運動 ( 每週3次，共3週，每次反覆次數12次，組間休息1分鐘，共5組 )；僅加壓於非慣用腳，加壓部位於大腿近端。在運動前及施行加壓訓練的每一週進行抽血，比較肌酸激酶 ( CK )、心肌性肌酸激酶 ( CK-MB )、乳酸脫氫酶 ( LDH )、麩氨基酸草醋酸轉氨基酵素 ( GOT ) 與麩氨基酸焦葡萄轉氨基酵素 ( GPT ) 之差異，及運動前、中、後之類胰島素生長因子 ( IGF-1 ) 之差異；並比較實驗處理前後對運動表現 (最大肌力、有氧能力及左右反應時間)之差異。結果： HOLR在實驗後於CK ( Pre: 147.1 ± 19.4, Week1: 361.4 ± 74.5 U/L, p < .05 )及LDH ( Pre: 163.4 ± 27.7, Week1: 199.6 ± 54.8 U/L, p < .05 ) 發炎指標僅第1週升高後，第2、3週皆持續降低，而GPT ( Pre: 9.0 ± 5.9, Week1: 10.0 ± 4.2, Week2: 18.6 ± 13.0 U/L, p < .05 ) 及CK-MB ( Pre: 5.3 ± 2.4, Week1: 7.6 ± 3.6, Week2: 12.9 ± 2.6 U/L, p < .05 )的反應升高持續到第2週，到第3週才降低；於IGF-1中並未達顯著差異；在最大等長肌力於慣用腳 ( Pre: 316.4 ± 71.7, Post: 249.1 ± 75.0 Nm, p < .05 ) 與非慣用( Pre: 293.8 ± 79.9, Post: 238.3 ± 58.3 Nm, p < .05 )皆顯著降低。結論： HOLR的運動模式引起體內肌肉損傷與增生的反應，雖產生了較大的發炎反應效果但伴隨著有肌力下降的現象，且於IGF-1中並未能觀察到顯著的差異。
Purpose: The aim of study was to investigate the effect of high vascular occlusion pressures (1.7 SBP) combined low-intensity resistance (30% 1RM) on post-exercise muscle growth hormone, inflammation and exercise performance. Methods: Fourteen wrestling team males (age: 21 ± 1.2 yrs; height: 170.7 ± 5.5 cm; weight: 73.7 ± 14.8 kg) were recruited in this study to perform bilateral leg extension (three week, three times a week, 5 sets, 12 repetitions with 1 min rest among all sets) blood occlusion only pressurized non-dominant leg. Blood samples were collected prior exercise (pre) and every week for analysis of creatine kinase (CK), creatine kinase MB (CK-MB), lactate dehydrogenase (LDH), glutamic oxaloacetic transaminase (GOT), glutamic pyruvic transaminase (GPT), and exercise pre, mid and post Insulin-like Growth Factor-1 (IGF-1); the maximal voluntary contraction strength, aerobic capacity and Reaction time of compare exercise pre and post. Results: LRHO in the experiment after the CK (Pre: 147.1 ± 19.4, Week1: 361.4 ± 74.5 U / L, p <.05) and LDH (Pre: 163.4 ± 27.7, Week1: 199.6 ± 54.8 U / L, p <.05) inflammatory markers only in first week increased, after second week are continuing to reduce; GPT (Pre: 9.0 ± 5.9, Week1: 10.0 ± 4.2, Week2: 18.6 ± 13.0 the U / L, p <.05) and CK-MB (Pre: 5.3 ± 2.4, Week1: 7.6 ± 3.6, Week2: 12.9 ±2.6, U / L, p <.05) continued increased into the second weeks , third weeks before decrease; but no significant differences in IGF-1; maximal isometric strength in the usual (Pre: 316.4 ± 71.7, Post: 249.1 ± 75.0 Nm, p <.05) and non-dominant (Pre: 293.8 ± 79.9, Post: 238.3 ± 58.3 Nm, p <.05) were significantly decrease. Conclusion: LRHO exercise can produce to inflammation response on the muscle, but muscle strength follow to decrease, and IGF-1 no significant difference. |
