The clothing manufacturer Venex Life-Science tracks the strategy to enhance recovery process through implementing platinum harmonized technology (PHT) into their Venex® Regeneration Wear. The proposed mechanisms of the regeneration wear are an increase of parasympathetic activity and an increase of the temperature due far-infrared radiation. The purpose of this study was to investigate potential effects of Venex regeneration wear on the recovery of neuromuscular, systemic and subjective parameters following exercise. In a randomized, single-blinded cross-over design, 13 strength-trained male participants performed two exercise sessions in one day. After the first exercise session and for 3 nights following the exercise day participants wore the Venex regeneration wear or a placebo product. Measures of isometric maximum voluntary contraction (MVC), voluntary activation (VA) and potentiated twitch torque (PTT) of the knee extensors, as well as maximum jump height during the Counter-Movement and Drop Jump, creatinkinase (CK) and subjective parameters (perceived pain, recovery condition and sleep quality) were obtained before and after each exercise session and 24, 48, and 72 hours after the first exercise session. MVC, PTT, CK and jump parameters changed over time during the exercise day as well as on the following days, however, there were no significant differences between treatments. Subjective parameters showed strong effect sizes (i. e. Cohen's d > 0.6) in favor for Venex but no significant differences between treatments. Based on these findings, it is concluded that wearing a platinum harmonized textile following exercise did not improve neuromuscular and systemic recovery in a trained male population to a statistical noticeable extent. However, the findings for the subjective parameters suggest some potential for enhanced recovery that requires further research.
服装制造商Venex生命科学公司制定了一项战略,即通过在其Venex®再生服装中采用铂金协调技术(PHT)来加快恢复过程。该再生服装的作用机制被认为是通过远红外辐射增加副交感神经活动并提高体温。本研究的目的是调查Venex再生服装对运动后神经肌肉、全身和主观参数恢复的潜在影响。在一项随机、单盲交叉设计中,13名经过力量训练的男性参与者在一天内进行了两次锻炼。在第一次锻炼后以及锻炼日之后的3个晚上,参与者穿着Venex再生服装或安慰剂产品。在每次锻炼前后以及第一次锻炼后24、48和72小时,测量了膝伸肌的等长最大自主收缩(MVC)、自主激活(VA)和增强抽搐扭矩(PTT),以及反向移动跳和下落跳时的最大跳跃高度、肌酸激酶(CK)和主观参数(感知疼痛、恢复状况和睡眠质量)。在锻炼日以及随后几天,MVC、PTT、CK和跳跃参数随时间变化,但各治疗组之间没有显著差异。主观参数显示出对Venex有利的强效应量(即科恩d>0.6),但各治疗组之间没有显著差异。基于这些发现,可以得出结论,锻炼后穿着铂金协调纺织品在统计学上并未显著改善训练有素的男性群体的神经肌肉和全身恢复。然而,主观参数的研究结果表明存在一些促进恢复的潜力,需要进一步研究。
