The effect of small-sided games and HIIT formats and competitive level on enjoyment and exercise intensity in young adult male soccer players.

This study aims to analyze the differences in Physical Activity Enjoyment Scale (PACES) scores and exercise intensity across small-sided games (SSGs) and high-intensity interval training (HIIT) formats among soccer players from Tier 2 and Tier 3 competitive levels. Utilizing a cross-sectional design, 77 male players (20.64 ± 1.56 years) participated in four training sessions under controlled conditions. Enjoyment was assessed with PACES, while exercise intensity was monitored through heart rate and rating of perceived exertion (RPE). The training formats included 1 v 1 and 5 v 5 SSGs and long and short HIIT formats. Players were categorized as Amateur (Tier 2) or Competitor (Tier 3) based on training volume and performance level. The training formats included 1 v 1 and 5 v 5 SSGs and long and short HIIT formats. The present study revealed significant differences in PACES scores across the different training formats (p < 0.001), with the 5 v 5 format yielding the highest scores and long HIIT the lowest. A significant interaction between training format and competitive level was observed (p = 0.011). Tier 2 players reported higher PACES scores in the 5 v 5, 1 v 1, and Short HIIT formats compared to Tier 3 players. SSGs and HIIT formats significantly influence enjoyment, with smaller-sided formats (1 v 1) and short HIIT showing the highest enjoyment levels. Tier 2 players reported higher enjoyment and physical efforts than Tier 3 players, in 5 v 5, 1 v 1, and short HIIT formats. These findings show the importance of programming training sessions according to the competitive level of athletes to maximize enjoyment and manage effort in soccer training programs.
