补充竹叶提取物对大强度运动大鼠脑组织生化指标的影响

为了评价竹叶提取物在运动训练方面作为抗疲劳补剂的可行性，研究了大强度耐力训练及补充竹叶提取物对大鼠脑组织生化指标的影响。24只SD大鼠随机分为安静组、运动组和运动加药组，每组8只。运动组和运动加药组进行6周大强度跑台训练；运动加药组同时按300 mg·kg-1·d-1的用量灌服竹叶提取物悬浊液。结果表明：大强度耐力训练引起大鼠脑组织SOD、CAT活性、T-AOC水平显著降低，MDA含量显著升高；补充竹叶提取物抑制了大鼠脑组织SOD活性、CAT活性、T-AOC水平的降低及MDA含量的升高，并使大鼠力竭运动时间延长了28.87%，表明竹叶提取物适合作为抗疲劳补剂的原料。

Effect of supplementing bamboo leaf extract on brain biochemical parameters of rat experiencing high intensity exercise

In order to evaluate the feasibility of bamboo leaf extract （BLE） as an anti-fatigue supplements in sports training， the effect of high.intensity endurance training and supplementing BLE on brain biochemical parameters of rats was studied. Twenty four SD rats were randomly divided into quiet group， sport group and dosed sport group， with 8 rats in each. Sport group and dosed sport group experienced 6-week treadmill training. Dosed sport group was also fed 300 mg·kg-1·d-1 BLE suspension. The results showed that high-intensity endurance training caused significant decrease in SOD and CAT activity and T-AOC level， and significant increase in MDA content in brain， but taking BLE inhibited the downward trend of SOD and CAT activity and T-AOC level， the upward trend of brain MDA content and increased exhaustive exercise time by 28.87%. Above results indicated that BLE is suitable as raw material for anti-fatigue supplements.
