    60 people with the age range of 14 to 22 years were selected from among the available population with the opinion of a specialist doctor and participated in the research voluntarily. The number of samples was estimated by G* power statistical software, considering the average effect size of 0.5, power of 0.80, and alpha of 0.05. Among the statistical population, 60 subjects prone to anterior cruciate ligament injury were selected purposefully, taking into account 10% drop. Then they were randomly divided into 3 groups (jump-landing training group of 20 people, jumping-landing and strength training group of 20 people and control group of 20 people).
    A randomized, single-blind, parallel clinical trial study, 60 people were divided into two intervention groups and a control group, through web-based randomization.
    از بین جامعه در دسترس 60 نفر با دامنه سنی 14 تا 22 سال با نظر پزشک متخصص به صورت هدفمند با توجه به معیارهای ورود به تحقیق انتخاب شده و به صورت داوطلبانه در تحقیق مشارکت کردند. تکواندوکاران برای شرکت در پژوهش فرم رضایت نامه کتبی و همچنین فرم اطلاعات شخصی را که شامل اطلاعاتی در مورد ویژگی های شخصی (سابقه ورزشی تکواندو، سن، جنس، وزن و قد) همچنین سابقه آسیب اندام تحتانی بود، تکمیل کردند. لازم به ذکر است که تعداد نمونه توسط نرم افزار آماری برآورد حجم نمونه G* power با در نظر گرفتن اندازه اثر متوسط 5/0، توان 0.80 و آلفای 0.05 تخمین زده شد. از میان جامعه آماری تعداد 60 آزمودنی مستعد آسیب رباط صلیبی قدامی با در نظر گرفتن ریزش 10 درصد، به صورت هدفمند انتخاب شدند. سپس به طور تصادفی به 3 گروه ( گروه تمرینات پرش_فرود 20 نفر، گروه تمرینات پرش_فرود و قدرتی 20 نفر و گروه کنترل 20 نفر ) تقسیم شدند.
    یک مطالعه کارآزمایی بالینی تصادفی،یک سویه کور، موازی، ۶۰ نفر به دو گروه مداخله ویک گروه کنترل، از طریق تصادفی سازی تحت وب تقسیم شده اند.

    After physician examination and review of inclusion/exclusion criteria, the patient's personal information was recorded and the consent form was signed. Participants were equally divided into three groups: jumping-landing exercises with strength exercises, without strength exercises, and a control group. This single-blinded study (outcome assessors blinded to interventions and grouping) was conducted at the Movement Analysis Laboratory, Faculty of Physical Education, Kharazmi University. Exercises were performed for 6 weeks, three sessions per week.

    پس از بررسی توسط پزشک، بررسی معیارهای ورود و خروج، محقق اطلاعات شخصی بیمار را ثبت و وی فرم رضایت را امضا کرد. شرکت کنندگان به صورت مساوی به سه گروه تمرینات پرش- فرود با و بدون تمرینات قدرتی و یک گروه کنترل تقسیم شدند. این مطالعه یک سوكور که ارزیابی کننده های پیامد در مورد مداخله ها و گروه بندی کور می باشند. این مطالعه در ازمایشگاه آنالیز حرکت دانشکده تربیبت بدنی دانشگاه خوارزمی انجام شد. تمرینات به مدت 6 ھفته و سه جلسه در ھفته انجام شد.

    Randomization was done with the help of the online random number generation site (Kitset.ir). To group the participants, this site randomly showed us non-repeating numbers from 1 to 60, and according to the ID of the participants We put each person in a group.
    Randomization will be done by simple randomization individually and the sequence of random allocation will be determined using a computer program with the help of a web-based program (randomizer.org), by a member of the research team not involved in the selection of samples from sealed opaque envelopes with a random sequence will be used to conceal allocation. They will be assigned to two intervention groups and a control group.
    تصادفی سازی به کمک سایت تولید اعداد تصادفی آنلاین ( ( Kitset.ir انجام شد. که برای گروه بندی شرکت کنندگان، این سایت بصورت رندوم اعداد غیر تکراری را از شماره 1 تا 60 به ما نشان میداد و ما با توجه به آی دی شرکت کنندگان هر فرد را در یک گروه قرار دادیم. در هر پاکت 20 شماره یادداشت شد که گروه بندی توسط شخصی که هیچ دخالتی در تحقیق نداشت، توسط انتخاب پاکت های مهرو موم شده انجام شد.
    تصادفی سازی به صورت تصادفی ساده به صورت فردی و توالی تخصیص تصادفی را با استفاده از برنامه کامپیوتری با کمک برنامه تحت وب (randomizer.org)تعیین خواهد نمود، توسط یکی از اعضای تیم تحقیق غیردرگیر در انتخاب نمونه ها از پاکت نامه های غیرشفاف مهر و موم شده با توالی تصادفی به ترتیب برای پنهان سازی تخصیص استفاده خواهد شد. به دو گروه مداخله و یک کنترل تخصیص می یابند.
    In this study, the outcome assessor is blinded, meaning that he or she is unaware of the allocation of subjects to groups and which treatment intervention each group of subjects receives. This way, they do not make errors in their judgments in favor of a particular treatment intervention during the assessment before and after the protocol period.
    در این مطالعه فرد ارزیابی کننده پیامد کور می باشد، به این صورت که او از نحوه تخصیص ازمودنی ها در گروه ها و اینکه هر گروه از آزمودنی چه مداخله درمانی را دریافت میکنند اطلاعی ندارند. تا از این طریق در هنگام ارزیابی قبل و بعد از دوره پروتکل در قضاوت های خود دچار اشتباهاتی به نفع مداخله درمانی خاصی نشوند.

Protocol summary

Study aim
The effect of jump-landing and strength training on performance, dynamic balance, and selected kinetic and kinematic factors of taekwondo athletes (Poomsae) with dynamic knee valgus
Design
A randomized, single-blind, parallel clinical trial study, 60 people were divided into two intervention groups and a control group, through web-based randomization.
Settings and conduct
