Achilles tendinitis is one of the commonest injuries that happen to skaters. Roller skates traditionally have four wheels onto axles, one under the ball of the foot and one under the heel. Skaters have to maintain a closed kinematics chain which involves continuous trunk and hip flexion along with knee flexion and ankle dorsiflexion. It creates angular tension and strain in the muscles and tendons which can lead to different types of musculotendinous injuries. As not many studies has not been done on the prospect in India this study was done with a objective to compare the effect eccentric exercise and isometric exercise on Achilles tendinitis for skaters.
A Quasi-experimental study with 40 subjects of the age group between 15 and 25 was administered the VISA-A Questionnaire and VAS as outcome measures. A sample size of 40 was separated into two groups of 20 participants each into Group A (eccentric) and Group B (isometric). Pre-test and post-test were done using the VISA-A questionnaire and VAS Scale in the Study period- 4 weeks.
There was a significant difference during the comparison between pre-test and post-test values (p < 0.005) of isometric exercise and eccentric exercise by VISA-A questionnaire and VAS scale but there was insignificance during the comparison of post-test values (p > 0.005) of the same.
The study concludes that there is a significant improvement in Achilles tendinitis when assessed with VISA-A questionnaire and VAS Scale for both the exercise; that is, eccentric and isometric, individually but it isn't statistically significant enough to choose one method of intervention over the other.
跟腱炎是滑冰者最常见的损伤之一。传统的轮滑鞋有四个安装在轴上的轮子，一个在脚掌球部下方，一个在脚跟下方。滑冰者必须维持一个封闭的运动链，这涉及到持续的躯干和髋部屈曲以及膝关节屈曲和踝关节背屈。这会在肌肉和肌腱中产生角张力和应变，从而导致不同类型的肌肉肌腱损伤。由于在印度针对这方面的研究不多，本研究旨在比较离心运动和等长运动对滑冰者跟腱炎的影响。
一项准实验研究，对40名年龄在15至25岁之间的受试者进行了VISA - A问卷和视觉模拟评分法（VAS）测量。样本量为40，分为两组，每组20名参与者，分别为A组（离心运动组）和B组（等长运动组）。在为期4周的研究期间，使用VISA - A问卷和VAS量表进行前测和后测。
通过VISA - A问卷和VAS量表对等长运动和离心运动进行前测和后测值比较时存在显著差异（p < 0.005），但对相同的后测值进行比较时无显著差异（p > 0.005）。
该研究得出结论，使用VISA - A问卷和VAS量表评估时，两种运动，即离心运动和等长运动，对跟腱炎均有显著改善；但在统计学上，选择一种干预方法优于另一种方法的差异并不足够显著。
