اثر 8 هفته تمرین تای چی چوان و پیادهروی بر شاخصهای بیماریزای قلبی عروقی در زنان سالمند
Bibliographic record
Abstract
چکیده زمینه و هدف: با توجه به مشکلات قلبی عروقی که برای افراد سالمند به دلیل عدم تحرک کافی ایجاد میشود هدف از انجام پژوهش حاضر انجام 8 هفته تمرین تای چی بر عوامل بیماری قلبی عروقی شامل کلسترول (C)، تری گلیسیرید (TG)، لیپوپروتئین پر چگال (HDL-C) و لیپوپروتئین کم چگال (LDL-C) در زنان سالمند بود. مواد و روشها: 30 آزمودنی ساکن در یک خانه سالمندان شهر تهران در دو گروه تای چی و پیادهروی بهصورت در دسترس انتخاب شدند. در هفته اول و هفته هشتم نمونههای خونی از آزمودنیها جهت سنجش متغیرها گرفته شد و در دو گروه مورد مقایسه قرار گرفتند. جهت تجزیهوتحلیل دادهها از آزمون اسمیرنوف کلوموگروف و همچنین تی وابسته و مستقل استفاده شد. نتایج: نتایج درونگروهی و بین گروهی نشان داد که هر دو روش تمرینی میتوانند اثرات مثبتی بر کاهش و یا کنترل نیمرخ چربی اعمال کنند که این تغییرات در گروه تای چی بهتر و معنادار بود. نتیجهگیری: تای چی موجب کاهش معنادار در LDL-C و همچنین موجب افزایش معنادار در HDL-C شد ولی در مقایسه با گروه پیادهروی موجب تغییرات غیر معنادار در میزان کلسترول و تری گلیسیرید شد. واژههای کلیدی: بیماریهای قلبی و عروقی؛ چربی خون بالا؛ تای چی References - Cheng T O (2007) Tai Chi: the Chinese ancient wisdom of an ideal exercise for cardiac patients.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
