چکیده

هدف: فواید متابولیک انجام هر جلسه تمرینات معمول بیماران دیابتی فعال در شرایط آب در برابر خشکی نیاز به بررسی دارد. هدف پژوهش بررسی مقدار گلوکز، FFA، انسولین، ANP و اپی‌نفرین خون در حین رکابزنی در خشکی در برابر آب و همچنین در خلال دورۀ زمانی اولیۀ بازگشت به حالت اولیه بود.
روش‌ها: طرح پژوهش از نوع سری‌های زمانی با ترتیب تصادفی معکوس بود. دوازده زن دیابتی یائسه (سن 3/2±76/66 سال)، ابتدا شش هفته تمرین تناوبی را تجربه کردند و سپس به دنبال آزمون تحمل گلوکز، در سه جلسۀ مجزا (با فاصلۀ یک هفته) شامل شرایط کنترل، ورزش در آب و ورزش در خشکی آزمون شدند. در هر دو جلسۀ ورزش در خشکی و آب، سه تناوب 10 دقیقه‌‌ای رکابزنی با شدت 40 درصد توان هوازی بیشینه انجام گرفت و پنج بار خون‌گیری در مراحل پیش از ورزش، بلافاصله پس از ورزش و همچنین در دقایق 60، 90 و 120 پس از ورزش به‌عمل آمد. داده‌ها با تحلیل واریانس اندازه‌گیری مکرر عاملی 5×3 (شامل سه سری زمانی پنج تکراری) تحلیل شد.
نتایج: رکابزنی در هر دو شرایط آب و خشکی سبب کاهش گلوکز (20- و 17- درصد)، انسولین (39- و 37- درصد)، و FFA سرم (61- و 55- درصد) و از سوئی افزایش مقدار ANP (169 و 52 درصد) و اپی‌نفرین (43 و 82 درصد) سرم شد (05/0>P). پس از توقف رکابزنی در هر دو شرایط، مقدار انسولین، FFA و ANP افزایش یافت، درحالی‌که گلوکز و اپی‌نفرین کاهش یافتند (05/0>P). در تمام موارد سطوح سرمی متغیرها در حین رکابزنی در آب کمتر از رکابزنی در خشکی بود (05/0>P).
 نتیجه‌گیری: در صورت انجام هر جلسه تمرینات ورزشی بیماران دیابتی دارای سابقۀ تمرین منظم در آب، فواید متابولیکی بهتری نسبت به ورزش در خشکی حاصل می‌شود که این مسئله در دو ساعت متعاقب پایان ورزش نیز ادامه می‌یابد، ولی به‌دلیل کمبود شواهد و محدودیت‌های پژوهش همچنان به بررسی بیشتری نیاز است.

چکیده [English]

Purpose: The metabolic benefits from each individual exercise session (in land vs. water condition) designated for trained diabetic patients remain to be evaluated. The aim of this study was to invesigate blood glucose, FFA, insulin, ANP and epinepherin levels during land vs. water cycling session and also following early post exercise recovery period.
Methods: This was a case-crossover study with time series method. Twelve postmenopausal diabetic women (age 66.76 ± 2.3 years), participated in three distinct test sessions with glucose tolerance test at the begining, at control, water and land exercise conditions, following participating in an interval training protocol (six weeks). Both aquatic and land exercise sessions were consisted of three sets of ten min cycling intervals at 40% of Vo2max. Blood sampling were done in five occasions each session including: pre exercise, immediately post exercise and also at 60th, 90th and 120 th min of post exercise period. The data were analyzed by factorial (3×5; three five phase series) ANOVA for repeated measurements using SPSS 21.
Results: acute cycling in both water and land conditions decreased blood glucose (-37% and -39%), insulin (-20% and -17%) and FFAs (-61% and -55%), while serum ANP (169% and 52%) and epinephrine (43% and 82%) were up regulated (P < 0.05). Serum Insulin, FFAs and ANP levels were elevated also followingthe exercise cessation, with a synergic suppression of blood glucose and epinephrine levels (P < 0.05). All measured variables levesl were lower in water exercise session compared to land exercise (P < 0.05).
Conclusions: more beneficial metabolic effects could be provided with an individual training session performed by regularly exercising diabetic patients in water condioton, compared to land exercise and this trend was continued through two hours of recovery period. However; more investigations remain to be done because of the lack of similar evidence and study limitations.
