| سابقه و هدف: هدف از مطالعه حاضر ارزیابی اعتبار آزمون تغییر یافته کانکانی برای تعیین حداکثر لاکتات حالت پایدار در مردان جوان ورزشکار بود. روش شناسی: 11 کشتی‌گیر مرد (سن: 3/1 ± 01/19 سال، قد: 54/3 ± 64/176 سانتی‌متر، :BMI 0 /4±7/23 کیلوگرم/مترمربع، VO2max: 67/3 ± 08/51 میلی لیتر/کیلوگرم/دقیقه) به صورت هدفمند انتخاب شدند و آزمون‌های ورزشی فزاینده در دو جلسه با فاصله 48 ساعت؛ 1- پروتکل تغییر یافته کانکانی (5/1 % شیب، سرعت شروع Km3 ، افزایش سرعت یک کیلومتر هر 60 ثانیه) 2- آزمون مبنا: فزاینده تا سطح MLSS ، را بر روی نوارگردان اجرا کردند. HRDP با استفاده از مدل S.Dmax تعیین شد. برای ارزیابی همگرایی بین دو روش، از مدل گرافیکی بلاند-آلتمن و همگرایی درونی(ICC) استفاده شد. یافته‌ها: نتایج نشان داد که بین HRDP بدست آمده از آزمون کانکانی، با HRMLSS در روش مبنا همگرایی بالایی وجود دارد (96/1± ، CI : 95%، 4/2- تا 7/7 ضربه/دقیقه ؛ ICC: 81/0). همچنین، بین سرعت در HRDP (SpeedHRDP) و سرعت در بیشینه فلات لاکتات (SpeedMLSS) همگرایی بالایی مشاهده شد (96/1± ، CI : 95%، 57/0- تا 95/0+ کیلومتر در ساعت؛83/0= ICC). نتیجه گیری: HRDP و SpeedHRDP بدست آمده در آزمون تغییر یافته کانکانی در کشتی گیران جوان می‌تواند مقادیر HRMLSS و SpeedMLSS را پیشگویی نماید. به نظر می رسد این آزمون بتواند جایگزین مناسبی برای روش‌های تهاجمی در تعیین آستانه بی‌هوازی باشد و به عنوان یک آزمون آسان، غیرتهاجمی وکوتاه برای تجویز شدت تمرین در ورزشکاران به کار رود. | ||

| Background & Purpose: The aim of this study was to survey the validity of the modified Conconi running test for determining of the maximal lactate steady state in young male athletes. Methodology: 11 young wrestler men were selected (Mean ± SD Age 19.01 ± 1.3 yrs., Height 176.64 ± 3.54 cm, BMI: 23.7 ± 4.0 kg/m2, VO2max: 51.08 ± 3.67 ml/kg/min) and incremental exercise tests in two sessions with an interval of 48 hours {1- accordance to conconi modified protocol (slope:1.5%, began speed: 3 km/h, increasing the speed of one Km per 60 sec) 2. criterion test: Increasing up MLSS }performed on a treadmill. The HRDP was determined by the S.Dmax model. Bland-Altman graphical model and Interclass Correlation Coefficient (ICC) statistical tests were used to evaluate the absolute agreement of the methods. Results: The results indicated high agreement between HRDP and HR of the criterion method (HRMLSS) (±1.96; 95% CI= -2.4 to +7.7 b/min; ICC= 0.81). Moreover, high agreement was observed between speed at HRDP (SpeedHRDP) and speed of the criterion method (SpeedMLSS) (±1.96; 95% CI= -0.57 to +0.95 km/h; ICC= 0.83). Conclusion: The HR and velocity at the deflection point determined by the modified Conconi running test could predict the HRMLSS and speedMLSS. It seems that this test could be a good alternative to more invasive method to determine the anaerobic threshold test as a simple, noninvasive short for the prescribed exercise intensity in athletes used. | ||
