Effects of a period of small-sided games + high-intensity interval training versus high-intensity interval training on physical Performance of youth soccer players

In recent years, various training methods have been used, including Small-sided games and High-intensity interval training (HIIT) to improve the skills and physical abilities of soccer players. The aim of this study was to compare the effect of a period of Small-sided games +High-intensity interval training (SSG+HIIT) Versus High-intensity interval training (HIIT) on some physical performance of soccer players.Thirty-six soccer players (Mean age ۱۴±۱.۱yr; Weight ۴۸.۶±۷.۵۳ kg) participated in this study. The HIIT+SSG group completed ۸-week (۵×۵, ۴×۴, ۳×۳ games, on a ۲۵×۳۵ m pitch) two sessions, and HIIT consisted of intermittent a ۳min running at ۶۵-۹۵%VIFT speed separated by a ۳min passive recovery. The HIIT protocol consist of ۲x۳ min work with ۳ min of passive recovery in-between, two sessions weekly lasting ۲۴min. The ۳۰m Sprint, change of direction, ۱۰m acceleration, and heart rate (with Polar team model H۱۰) of participants were measured before and after exercise interventions using validated tests. The level of significance was set at P≤۰.۰۵, and data were analyzed using SPSS Statistics for Windows.The findings showed that there were no significant differences in acceleration (HIIT: ۶.۳ vs. HIIT+SSG: ۷.۴%), ۳۰m sprint (HIIT: ۳.۴ vs. HIIT+SSG: ۴.۲%), maximum heart rate (HIIT: ۱.۴ vs. HIIT+SSG: ۱.۴%), average heart rate (HIIT: ۳.۱ vs. HIIT+SSG: ۴.۳%), hoper index (HIIT: ۹.۲vs. HIIT+SSG:۹.۱%), and rate of perceived exertion (HIIT: ۱۵.۱vs. HIIT+SSG: ۱۹.۷ %) variables between two groups (P>۰.۰۵). On the other hand, HIIT+SSG combined exercises induced more improvements in the change of direction in HIIT + SSG than HIIT group (HIIT: ۴.۲vs. HIIT + SSG: ۶%; p=۰.۰۰۲).The HIIT+SSG exercises were more effective to develop change of direction, due to their nature in soccer players, but in ۳۰m sprint and ۱۰m acceleration, and other performance capacities, the effectiveness of both training methods was the same.
