Verbal Encouragement Improves Game Intensity, Technical Aspects, and Psychological Responses During Soccer-Specific Training.

Background: Soccer match outcomes rely on technical accuracy, intensity of play, and athlete motivation, and these parameters can be developed during sport-specific practice such as during small-sided games (SSGs). Verbal encouragement as a coaching technique improves exercise intensity and athlete enjoyment (indicative of motivation), but the impact on technical performance alongside these critical parameters remains unknown.

Purpose: To examine the effects of verbal encouragement on technical performance, exercise intensity, and enjoyment during SSGs.

Methods: Sixteen male youth soccer players (mean [SD]; age: 17.2 [0.4] y; height: 176.3 [7.0] cm; body mass: 68.0 [4.1] kg; body fat: 11.9% [2.2%]) completed 4 sessions of 4-per-side SSG without a goalkeeper. Two sessions were conducted as SSGs with verbal encouragement and 2 without verbal encouragement. Each SSG lasted 25 minutes (4 × 4-min work, 3-min passive recovery between bouts) on a 25 × 35-m pitch. Heart rate (HR) was continuously recorded, and rating of perceived exertion was collected after each SSG. Video analysis was used to quantify technical actions during SSG. Enjoyment was assessed after each SSG using the Physical Activity Enjoyment Scale.

Results: Paired t tests revealed that SSGs with verbal encouragement induced higher HR (% maximum HR and mean HR), rating of perceived exertion, and Physical Activity Enjoyment Scale score than SSGs without verbal encouragement (all P < .001, all d ≥ 0.92, large). Compared with SSGs without verbal encouragement, SSGs with verbal encouragement resulted in an increased percentage of successful passes (P < .001, d = 0.73, medium) and number of interceptions (P < .001, d = 0.89, large) and fewer lost balls (P < .001, d = 0.68, medium).

Conclusions: Coaches should use verbal encouragement during SSGs to improve physical effort, technical performance, and psychological status in soccer players.
