The Effect of 6 Weeks of Interval Training Based on Heart Rate Deflection Point (HRDP) Extracted from D-Max Method on Blood Lactate Changes, Time to Fatigue and Performance of Young Soccer Players

The aim of this study was the effect of 6 weeks of interval training based on heart rate deflection point (HRDP) extracted from D-Max method on blood lactate, performance and time to fatigue of young soccer players. 20 soccer players volunteered to participate in this study and were randomly divided into two groups: training (n=10) and control (n=10). Control group performed their club training 3 sessions a week for 6 weeks and training group conducted the interval training with equivalent intensity of HRDP based on D-Max method in addition to their club training. The dependent and independent t tests were used to determine intragroup and intergroup differences. The results showed that time to fatigue (P=0.00) and produced lactate (P=0.02) significantly increased only in the training group, but performance was improved in both training (P=0.02) and control (P=0.04) groups. Also, the training group showed significantly better effects on lactate (P=0.01), time to fatigue (P=0.03) and performance (P=0.00) in soccer players. Generally, coaches and soccer players are recommended to use interval training with equivalent intensity of HRDP extracted from D-Max method combined with their club training in order to achieve their training goals.
