Global Active Stretching is a relatively recent yet little studied stretching method. It differs from the most popular methods by targeting muscle chains and integrating stretching with muscle contractions, which may eventually avoid the post-stretching reduction of strength that occurs in other methods.
To verify the immediate effects of Global Active Stretching on muscle strength and flexibility in individuals with short hamstrings.
A single-blind randomised controlled trial was carried out on 30 volunteers with more than 20° in the active knee extension test, randomly assigned to three groups: the experimental group (Global Active Stretching exercise); the placebo group (Global Active Stretching initial position without stretching); and the control group (lying down). The active knee extension and fingertip-to-floor tests assessed hamstring and posterior chain flexibility. Hamstring and quadriceps strength were assessed using the peak torque evaluation in the Biodex System 4PRO. Assessments took place before and immediately after the 15-minute intervention. The ANOVA and the paired t test were used (α = 0.05).
The experimental group had a significant increase in flexibility in both the fingertip-to-floor test (8.3 cm) and the active knee extension test (6.3°) when compared to the placebo and control groups (p < 0.05), while no differences in strength were observed (p > 0.05).
Global Active Stretching immediately increased hamstring flexibility without significantly reducing muscle strength. Thus, individuals seeking to enhance their short-term flexibility can benefit from this programme in a single session without compromising performance.
整体主动拉伸是一种相对较新但研究较少的拉伸方法。它与最流行的方法不同，其针对肌肉链并将拉伸与肌肉收缩相结合，这最终可能避免其他方法中出现的拉伸后力量下降。
验证整体主动拉伸对腘绳肌短缩个体肌肉力量和柔韧性的即时影响。
对30名在主动膝关节伸展试验中超过20°的志愿者进行单盲随机对照试验，随机分为三组：实验组（整体主动拉伸运动）；安慰剂组（处于整体主动拉伸初始位置但不进行拉伸）；对照组（躺下）。通过主动膝关节伸展和指尖触地试验评估腘绳肌和后链的柔韧性。使用Biodex System 4PRO中的峰值扭矩评估来评估腘绳肌和股四头肌的力量。在15分钟干预前后进行评估。采用方差分析和配对t检验（α = 0.05）。
与安慰剂组和对照组相比，实验组在指尖触地试验（8.3厘米）和主动膝关节伸展试验（6.3°）中的柔韧性均有显著提高（p < 0.05），而力量方面未观察到差异（p > 0.05）。
整体主动拉伸可立即提高腘绳肌柔韧性，且不会显著降低肌肉力量。因此，寻求增强短期柔韧性的个体可以在单次训练中从该方案中受益，而不会影响运动表现。
