The Comparison of three Protocol on Ttreadmill in Heart Rate Deflection Point among Active Male students .

خلاصه انگلیسی

One of the numerous methods for determining the upper limit of individual aerobic metabolism is the Heart rate test. It is a simple, non blood based test, which can give an indication of an athlete's condition or state of training. It is an extremely reliable and powerful predictor of performance in an aerobic exercise. It is based on the correlation between the anaerobic threshold and a deflection point in the heart rate during an incremental exercise test. The aim of the study to compare three Protocol on treadmill in Heart Rate Deflection Point among Active Male students in University of Mohaghegh Ardabili. Thirty young healthy male subjects with average age of 21.8± 0.2 , weight of 61.8 ± 2.1, height 173± 2 and Vo2max of 46.83 +2.6 lit/min and performed three incremental exercise test (Kippers, Jones & Doust, Gaisel & Hofmann ) until voluntary exhaustion. Polar Ventage Sport Tester XL was used to monitor heart rate performance throughout protocols. Anaerobic threshold in this tests was determine to Heart rate deflection point. The results showed that Heart rate deflection point was determine in all tests. Anaerobic threshold in Kuipers and Jones & Doust tests was not significantly different,although Gaisel & Hafmann test was significantly higher compared with Kuipers and Jones & Doust tests.These methods being used to determine the anaerobic threshold non-invasively, in practice it is easy-to-apply and accurate method to use subjects presenting a heart rate deflection.
