Verbal encouragement (VE) is considered as external motivation provided by physical education teacher. For this reason, this study aimed to examine the effects of VE on psychophysiological and affective responses during small-sided games (SSG). Sixteen male school students (age: 17.37 ± 0.48 years) completed four sessions of a 4-a-side SSG. Two sessions occurred with VE (SSGE), and two sessions did not include VE (SSGNE). Heart rate was continuously recorded, and rating of perceived exertion (RPE) and blood lactate concentration ([La]b) were measured after each training session. Physical enjoyment was assessed after each protocol. Mood state was recorded before and after each training session using the profile of mood-state. HR max, [La]b, RPE, Physical enjoyment, and vigor were higher in SSGE compared to SSGNE (all, p < 0.001). The SSGE and SSGNE resulted in a decreased total mood disturbance (TMD) (p = 0.001, ES = 0.60; p = 0.04, ES = 0.33, respectively) and tension (p < 0.001, ES = 0.91; p = 0.004, ES = 0.47, respectively), and the vigor was increased after the SSGE (p < 0.001, ES = 0.76). SSGE and SSGNE induce similar improvement in TMD and tension. However, SSGE induced higher physiological responses, RPE, enjoyment, and positive mood than SSGNE. Physical education teachers could use VE during specific soccer sessions to improve physical aspects, enjoyment, and mood in participants.

The general and sports psychology research is limited regarding the difference between the effects of verbal encouragement (VE) or compliment methods during high-intensity functional exercise testing. The purpose of this study was to explore the effects of VE and compliments on the performance of the repeated change-of-direction (RCOD) sprint test. A total of 36 male students in secondary school participated voluntarily in the study. They were divided equally into three homogeneous groups [VE group, compliment group (CG), and control group) and performed a standardized one repetition RCOD. The RCOD (6 × 20 m with 25-s active recovery) test consisted of a 100°change in the direction at every 4 m. Outcomes included performance indices (fast time, average time, and total time), rating of perceived exertion (RPE), and feeling scale scores. VE and the compliment increased the performance indices and RPE compared with the control group. In conclusion, VE during the exercise testing would be more beneficial for optimal performance and RPE compared with the compliment and control groups. However, the moods, during RCOD, reproduce more positively during compliment conditions than the VE and control groups.

The aim of the study was to compare the effect of additional practice/training of small-sided games (SSG) or repeated sprints (RS) on mood state, and physical performance in professional soccer players. Twenty four professional soccer players took part in this study (age: 17 ± 0.19 years). Participants were divided into two groups: small-sided gamed group (GSSG) performed 3 bouts of SSG (3 versus 3 players on 25 × 30 m pitch size) and repeated sprint group (GRS) performed 3 bouts of RS (6 × 40 + 40-m sprint with 20s of passive recovery in-between). Both groups were trained over a period of seven weeks (2 sessions/weeks) with the usual practice. The profile of mood state (POMS), the YOYO intermittent recovery test (YOYOTRT), sprint 10-m and five-jump test were conducted before and after training program. After 7 weeks of training, no changes in mood were determined, but run distance improved in both groups. Sprint time and leg strength improved in the RSG only. Coaches and physical trainers could choose between these two training modalities according to the objective of their training, keeping in mind the brief and intense actions advantages of the RS shown in the present study.

The purpose of the study was to examine the effects of verbal interaction between students on skill development and soccer game performance within a socio-constructivist perspective and a cooperative learning model in team-sport teaching. In addition, the usefulness of open verbalization was manifested as follows: (1) a social tool for both actors (teachers and students) to collect and manage reports on their thought processes; (2) a tool to stimulate reflection and critical reflection on performance to induce transformation during game action projects. Participants were 18 boys and 12 girls aged (15 ± 0.4 years) from a Tunisian school (ninth grade). They were placed in either the experimental group (with verbal interaction) or the comparison group (without verbal interaction) and then were tested before and after a 12-lesson soccer unit (approximately two hours/week). Skill competence was assessed using three tests: a 15 m ball dribbling test, the Loughborough Soccer Passing Test (LSPT) and a shooting accuracy test. Game performance was measured using the Game Performance Assessment Instrument (GPAI) in which the outcome variables assessed included (a) decision-making (DM), (b) skill execution (SE), (c) support (S), (d) game performance (GP), and (e) game involvement (GI). While both groups showed significant improvements in their short-passing ability, no such improvements were found in dribbling and shooting. In contrast, only the verbal interaction group produced significant improvements in overall game performance. In conclusion, if the objectives of the physical education curriculum are to promote team-sport teaching methods and quality game play, and create a reflexive learner, verbal interaction may be an effective tool for developing tactical understanding through cooperative learning.
