To document and explain Yoga's effects on acupuncture meridian energies. To understand mechanisms behind Yoga's efficacy by testing links between yoga and traditional Chinese medicine.
THE STUDY COMPARED TWO GROUPS OF YOGA PRACTITIONERS: Novice and experienced. Novices consisted of 33 volunteers from a Swami Vivekananda Yoga Anusandhana Samsthana (S-VYASA) yoga instructor training module and the experienced practitioners were 20 resident SVYASA students. The intervention was 3 weeks of a yoga training program, new for the novices, but the lifestyle of the experienced group, who were therefore assessed only once. Novices were assessed on day 2 and 23 of their program at SVYASA's Yoga Medicine Hospital, making their data a pre-post, self-as-control, prospective study. Main outcome measures were mean acumeridian energy levels assessed by AcuGraph3 measures of electrodermal resistance at acupoints; additionally, gender differences, standard deviations (SDs) of all measures, and comparison of post and experienced group data.
Averaged energy levels significantly improved in all 24 meridians (maximum P = 0.032, 4-P < 0.01, and 19-P < 0.001). Females improved more than males (P < 0.05), both ending at similar levels to experienced practitioners, whose SDs were lower than novices on 19/24 meridians (mean F = 3.715, P = 0.0022), and 4/5 average variables.
AcuGraph3 electrodermal measures contain substantial information, P << 0.00001. Yoga-lifestyle practice can increase and balance acumeridian energies; long-term practice decreases group SD's. These three suggest reasons why yoga practice impacts health: One, increased prana levels are important; two and three, improved physiological regulation is the key. Further studies relating traditional Indian and Chinese medical systems are needed.
记录并解释瑜伽对经络能量的影响。通过测试瑜伽与中医之间的联系来了解瑜伽功效背后的机制。
该研究比较了两组瑜伽练习者：新手组和经验丰富组。新手组由来自辨喜瑜伽研究中心（S-VYASA）瑜伽教练培训模块的33名志愿者组成，经验丰富的练习者为20名S-VYASA住校学生。干预措施是进行为期3周的瑜伽训练项目，这对新手来说是新的，但对于经验丰富组而言是他们的生活方式，因此只对经验丰富组进行了一次评估。新手在其项目的第2天和第23天在S-VYASA瑜伽医学院接受评估，使其数据成为一项前后对照、自身对照的前瞻性研究。主要结局指标是通过AcuGraph3测量穴位处皮肤电阻来评估的平均经穴能量水平；此外，还包括性别差异、所有测量指标的标准差（SD）以及新手组与经验丰富组数据的比较。
所有24条经络的平均能量水平均有显著提高（最大P = 0.032，4条经络P < 0.01，19条经络P < 0.001）。女性的改善程度超过男性（P < 0.05），最终两组的水平与经验丰富的练习者相似，经验丰富组在24条经络中的19条经络上的标准差低于新手组（平均F = 3.715，P = 0.0022），以及5个平均变量中的4个。
AcuGraph3皮肤电测量包含大量信息，P << 0.00001。瑜伽生活方式的练习可以增加并平衡经穴能量；长期练习可降低组内标准差。这三点表明了瑜伽练习影响健康的原因：其一，增加普拉那水平很重要；其二和其三，改善生理调节是关键。需要进一步开展有关印度传统医学和中医系统的研究。
