摘要

本研究的目的是研究急性Zembrin®(Sceletium tortuosum)补充剂对非习惯阻力运动后肌肉酸痛、肌肉损伤标志物、情绪和运动表现的影响。未经训练的女性(n=16)被分为两组,采用不同的三天治疗方案:(1)安慰剂(PL)和(2)Zembrin®(ZEM)。在初次访视期间,测量基线感知疼痛、活动范围(ROM)、情绪状态(情绪状态概况(POMS)问卷)和血浆乳酸脱氢酶浓度(LDH),然后用非优势臂进行偏心二头肌卷曲方案。记录整个运动过程中的总重复次数和感觉用力率(RPE)。参与者随后立即、第二天和完成48小时随访前30分钟补充相应的治疗。在48小时的访视中,重复所有程序,并对感觉酸痛、ROM、LDH、情绪评分、总重复次数和RPE进行比较。研究结果表明,与PL组相比,短期补充ZEM可降低48小时时的疼痛感(p=0.020),并能更好地保存ROM(p=0.028)。从基线到48小时,无论治疗如何,情绪都会恶化(p=0.043),但与ZEM组相比,PL组的情绪下降更为严重(p<0.001)。在48小时,LDH水平(p=0.019)和RPE(p=0.008)更高,总重复次数更低(p<001)。尽管ZEM的短期饮食强化并没有改变运动表现或肌肉损伤的生物标志物,但目前的研究结果表明,补充ZEM可能能有效降低不习惯的偏心运动后的酸痛标志物并保持情绪。

Effects of Zembrin® (Sceletium tortuosum) Supplementation on Mood, Soreness, and Performance Following Unaccustomed Resistance Exercise: A Pilot Study
The purpose of this study was to investigate acute Zembrin® (Sceletium tortuosum) supplementation on muscle soreness, markers of muscle damage, mood, and exercise performance following unaccustomed resistance exercise. Untrained females (n = 16) were divided into two groups with a different three-day treatment regimen: (1) placebo (PL) and (2) Zembrin® (ZEM). During the initial visit, baseline perceived soreness, range of motion (ROM), mood state (profile of mood states (POMS) questionnaire), and plasma lactate dehydrogenase concentrations (LDH) were measured followed by the performance of an eccentric bicep curl protocol with their non-dominant arm. The total repetitions and rate of perceived exertion (RPE) were recorded throughout the exercise. The participants then supplemented with the corresponding treatment immediately following, the subsequent day, and 30 min prior to completing a 48 h follow-up visit. For the 48 h visit, all procedures were repeated and comparisons were drawn for perceived soreness, ROM, LDH, mood scores, total repetitions, and RPE. The findings indicate that short-term ZEM supplementation resulted in lower perceived soreness (p = 0.020) and a greater preservation of ROM (p = 0.028) at 48 h versus the PL group. Mood worsened from the baseline to 48 h regardless of the treatment (p = 0.043) but the decrements were exacerbated in the PL group compared with the ZEM group (p < 0.001). LDH levels (p = 0.019) and RPE (p = 0.008) were higher and total repetitions were lower (p < 0.001) at 48 h irrespective of the treatment. Although short-term dietary enrichment with ZEM did not alter the exercise performance or biomarkers of muscle damage, the current results suggest ZEM supplementation may be effective in reducing the markers of soreness and preserve mood following unaccustomed eccentric exercise.
