BACKGROUND
Consumption of nutritional supplements to optimize recovery is gaining popularity among athletes. Tomatoes contain micronutrients and various bioactive components with antioxidant properties. Many of the health benefits of tomatoes have been attributed to lycopene encouraging athletes to consume pure lycopene supplements. The aim of this study was to compare the effect of tomato powder and lycopene supplement on lipid peroxidation induced by exhaustive exercise in well-trained male athletes.
METHODS
Eleven well-trained male athletes participated in a randomized, double-blinded, crossover study. Each subject underwent three exhaustive exercise tests after 1-week supplementation of tomato powder (each serving contained 30 mg lycopene, 5.38 mg beta-carotene, 22.32 mg phytoene, 9.84 mg phytofluene), manufactured lycopene supplement (30 mg lycopene), or placebo. Three blood samples (baseline, post-ingestion and post-exercise) were collected to assess total anti-oxidant capacity (TAC) and variables of lipid peroxidation including malondialdehyde (MDA) and 8-isoprostane. Data were analyzed using repeated-measures of ANOVA at P < 0.05.
RESULTS
Tomato powder enhanced total antioxidant capacity (12% increase, P = 0.04). Exhaustive exercise, regardless of supplement/ placebo, elevated MDA and 8-isoprostane levels (P < 0.001). The elevation of 8-isoprostane following exhaustive exercise was lower in the tomato powder treatment compared to the placebo (9% versus 24%, p = 0.01). Furthermore, following exhaustive exercise MDA elevated to a lower extent in tomatoe powder treatment compared to the placebo (20% versus 51%, p = 0.009). However, such differences were not indicated between lycopene and placebo treatments (p > 0.05).
CONCLUSION
Beneficial effects of tomato powder on antioxidant capacity and exercise-induced lipid peroxidation may be brought about by a synergistic interaction of lycopene with other bioactive nutrients rather than single lycopene.
背景
为了优化恢复，运动员越来越多地服用营养补充剂。西红柿含有具有抗氧化特性的微量营养素和各种生物活性成分。西红柿的许多健康益处归因于番茄红素，这促使运动员食用纯番茄红素补充剂。本研究旨在比较番茄粉和番茄红素补充剂对经过训练的男性运动员剧烈运动引起的脂质过氧化的影响。
方法
11 名经过训练的男性运动员参加了一项随机、双盲、交叉研究。每位受试者在服用番茄粉（每份含有 30mg 番茄红素、5.38mg β-胡萝卜素、22.32mg 八氢番茄红素、9.84mg 六氢番茄红素）、番茄红素补充剂（30mg 番茄红素）或安慰剂后进行 3 次剧烈运动测试，每周补充 1 次。采集 3 份血样（基线、摄入后和运动后）以评估总抗氧化能力（TAC）和脂质过氧化变量，包括丙二醛（MDA）和 8-异前列腺素。使用重复测量方差分析进行数据分析，P<0.05 为差异有统计学意义。
结果
番茄粉增强了总抗氧化能力（增加 12%，P=0.04）。剧烈运动无论补充剂/安慰剂如何，均会升高 MDA 和 8-异前列腺素水平（P<0.001）。与安慰剂相比，在番茄粉治疗后 8-异前列腺素的升高幅度较低（9%对 24%，p=0.01）。此外，与安慰剂相比，在番茄粉治疗后 MDA 的升高幅度较低（20%对 51%，p=0.009）。然而，在番茄红素和安慰剂治疗之间没有显示出这种差异（p>0.05）。
结论
番茄粉对抗氧化能力和运动引起的脂质过氧化的有益影响可能是由于番茄红素与其他生物活性营养素的协同作用，而不仅仅是单一的番茄红素。
