The main target of this study was to measure the influence of sumac juice drink on muscle indices and pain during an acute, intense exercise for 30 days. Forty healthy volunteers (15-25 years) were involved in aerobic exercise program for 4 weeks. Participants ingested sumac juice or placebo drink twice daily for 30 days. All participants were subjected for the evaluation of pain and estimation of serum: creatine kinase (CK), lactic acid dehydrogenase (LDH), troponin I, hydroxyproline (hyp), total antioxidant capacity (TAC), and in vitro antioxidant activity of sumac juice using pre-validated visual analog scale, colorimetric and immunoassays. The participants of both groups, placebo and sumac, showed an increment in pain scores both during exercise and post-exercise intervals. However, the sumac juice group showed a significant smaller increase in the pain scores compared to the placebo group. Participants in the sumac juice group were more willing to use the drink in the future. They achieved a higher satisfaction of sumac juice in ameliorating and the reduction of pain. Also, the sumac group showed a significant enhancement in the level of CK, LDH, troponin I, hyp, along with significant increase in serum (TAC) compared to the placebo group. The protective activity of muscle may relate to the antioxidant activity of phenolic component(s) in sumac juice as measured by 1,1-diphenyl-2-picryl-hydrazyl (DPPH) radical scavenging (87.9%) and β-carotene-linoleic acid (68.7%) assays. These data suggest that oral administration of sumac juice may have a beneficial effect on muscle performance among athletes.
本研究的主要目的是测量漆树果汁饮料对急性剧烈运动30天期间肌肉指标和疼痛的影响。40名健康志愿者（15 - 25岁）参与了为期4周的有氧运动计划。参与者每天两次摄入漆树果汁或安慰剂饮料，持续30天。所有参与者均接受疼痛评估，并通过预先验证的视觉模拟量表、比色法和免疫测定法评估血清中的肌酸激酶（CK）、乳酸脱氢酶（LDH）、肌钙蛋白I、羟脯氨酸（hyp）、总抗氧化能力（TAC）以及漆树果汁的体外抗氧化活性。安慰剂组和漆树组的参与者在运动期间和运动后间隔的疼痛评分均有所增加。然而，与安慰剂组相比，漆树果汁组的疼痛评分增加幅度明显较小。漆树果汁组的参与者未来更愿意饮用该饮料。他们对漆树果汁在缓解和减轻疼痛方面的满意度更高。此外，与安慰剂组相比，漆树组的CK、LDH、肌钙蛋白I、hyp水平显著提高，血清（TAC）也显著增加。通过1,1 - 二苯基 - 2 - 苦基肼（DPPH）自由基清除（87.9%）和β - 胡萝卜素 - 亚油酸（68.7%）测定法测得，肌肉的保护活性可能与漆树果汁中酚类成分的抗氧化活性有关。这些数据表明，口服漆树果汁可能对运动员的肌肉表现有有益影响。
