Original Title:
Φυσιολογικές αποκρίσεις κατά τη διαλειμματική άσκηση υψηλής έντασης και σύγκριση δύο πρωτοκόλλων προπόνησης
Summary:
Aerobic capacity and explosive power are important features of performance in soccer. The study aimed to examine the physiological responses of two high-intensity interval training protocols, the fatigue they induce in the Central Nervous System (CNS) and the rating of perceive exertion (RPE). Fifteen elite young soccer players in random order were divided into two groups that performed one of two 2 x 6-minute protocols with a 3-minute recovery between sets. One group (GΑ10) performed running for 10 s and 10 s passive recovery and the other group (GΒ15) performed running 15 s with 15 s passive recovery at the same intensity of 100% of the velocity maximal oxygen consumption (vV̇O2max). The body composition was calculated in both groups and they executed an outdoor field test to identify V̇O2max. An intervention program lasted 4 weeks with 2 times per week, where the players performed 2 sets of 6 minutes. At the end of the 4 weeks, repeated measurement followed to identify the differences. The control group (CG) was restricted to the competition program without performing an intervention program. From the results emerged a significant improvement in the distance covered after the intervention program in both groups (GΑ10: 320.0±128.58 meters and GΒ15: 175.0±120.83 meters respectively, p<0.05). Between the two groups, GΑ10 showed higher values (p<0.05) than GΒ15 in the total distance covered. Furthermore, higher RPE was presented in GΒ15 compared to GΑ10 (p<0.01), while CMJ showed no change in both groups. In conclusion, high intensity interval training (HIIT) indicated better results in short-term work and lower values in RPE but neither method induces fatigue in the central nervous system.
