Introduction: This study aimed to compare the effects of two training methods, "Small-Sided Games" (SSGs) and "divergent thinking" (DT) training, on self-efficacy and enjoyment of physical activity in young male soccer players.

Research method: The quasi-experimental research method with a pre-test and post-test design included two experimental groups and a control group. This study was conducted over eight weeks, including pre-test and post-test sessions and practice during soccer school practices. The pre-test included completing a self-efficacy and enjoyment of physical activity questionnaire, one week before the start of the intervention. Players were homogeneously assigned to one of two experimental groups (DT group and SSG group) and control group according to the pre-test results. The intervention phase consisted of 18 training sessions lasting 20 minutes. The post-test was conducted according to the pre-test.

Results: The results of the mixed ANOVA showed a significant difference between the pre-test and post-test of the two DT and SSG groups, so that it can be said that the SSG group had a greater impact on self-efficacy and enjoyment of physical activity compared to the DT group and both groups had a greater impact on self-efficacy and enjoyment of physical activity compared to the control group, with 77% and 75% of changes, respectively. No significant difference was observed in the control group.

Conclusion: SSG training, by providing dynamic and variable training environments, creates internal motivation, enjoyment, self-efficacy, self-confidence and ultimately greater participation of young players in training.
