Acute Effects of the Number of Players and Scoring Method on Physiological, Physical, and Technical Performance in Small-sided Soccer Games

This study aims to examine the effect of differences in the number of players and scoring method on heart rate responses, time-motion characteristics, and technical/tactical performance during small-sided soccer games. Ten male amateur soccer players (26.4 +/- 5.3 years old, 8.4 +/- 3.2 years of practice, 179.3 +/- 5.2 cm body height, 71.2 +/- 7.1 kg body weight, 45.8 +/- 2.6 ml.kg(-1)min(-1)VO(2)max) from the Portuguese regional league played nine different small-sided games (i.e., 3 formats x 3 scoring methods). The study used two-way MANOVA, two-away ANOVA, and one-way ANOVA, depending on the specific procedure for the analysis. Compared with other formats, 2v2 induced significantly greater values of technical/tactical indexes (p = 0.001), 3v3 induced significantly higher %HRreserve values (p = 0.001), and 4v4 led to significantly greater distance coverage and speed (p = 0.001). The study provided evidence for coaches to set different small-sided game conditions depending on the training purpose in terms of physiological, physical, and technical performance.
