Internal and External Load Variations in Young Students: Comparisons between Small-Sided Games and Small-Sided Games Combined with Strength Training during Physical Education Classes

Abstract: The purpose of this study was to compare the effects of internal and external load in soccer small-sided games (SSGs) and a strength program based on CrossFit combined with SSGs for 7 weeks. Fifty-five students participated in this research (age: 9.04 ± 0.19 years) and were randomly assigned to SSGs (n = 27) or strength combined with SSGs (n = 29) group. Two sessions/week were implemented. The results revealed that internal load on SSGs promoted higher levels (p ≤ 0.001; d = 0.35) of light physical activity (P… Show more

“…In contrast to the present study (5 vs. 5 format), these authors referred to the 12 vs. 12 playing format as a full game. As such, the significant differences found could be due to the presence of more players, which reduced ball contact [25].…”

“…The aforementioned organizational and pedagogical elements also facilitate the teaching-learning process and the attainment of educational objectives. Some of these elements have been studied to discover the intensity levels (iTL-HR) of PE classes both in primary and secondary education, in the former to compare the HRs after the implementation of two teaching programs, each based on a different technical and tactical methodology and directed toward the teaching of basketball [22] and soccer [23], to contrast the HRs and the percentage of time that the students were recording MVPA values, taking into account the type of participation-consecutive (rows) and simultaneous (circuits)-after practicing different motor abilities like locomotion, jumps, shooting, and receiving [24], or to understand the effects of formative soccer programs based on Small-Sided Games (SSGs) and strength training compared with SSGs on the HR [25]. In secondary education, we also analyze the differences between the HR and the percentage of time the adolescents recorded MVPA values after playing in two situations or play formats-SSGs and large-sided games or full games [14]-or determine the time spent in MVPA values according to the sport discipline: individual sports, team sports, traditional games, and dances [12].…”

“…For the selection of dependent variables, we used those presented in the scientific literature on youth football players [ 42 , 43 , 44 , 45 , 46 , 47 ]. In this way, the variables of distance covered, distance in speed sections, number of accelerations and decelerations, maximum acceleration and deceleration speed, maximum speed, and player load were selected ( Table 2 ).…”
