Background: Mental training and toughness play an important role as well as physical training and toughness in increasing the performance of an athlete.

Aim: This study aimed to i) evaluate the mental training and mental toughness levels of elite boxers in terms of various variables, ii) examine the relationship between mental training and mental toughness levels, and iii) investigate the predictive level of mental toughness levels of mental training levels.

Methods: The sample of the study consisted of 191 elite boxers. The data of the study were collected with the online questionnaire method using the Mental Training Inventory in Sports and the Mental Toughness Inventory in Sports. SPSS package program was preferred for data analysis and independent samples t-test was used for pairwise comparisons and one-way analysis of variance was used for multiple comparisons. Pearson Product Moments Correlation Coefficient (r) was used to test the relationship between mental training and mental toughness in elite boxers, and linear regression analysis was used to determine the ratio of mental training to predict mental toughness level.

Results: While the digital game playing level of secondary school students was low, their level of loneliness was found to be moderate, and it was determined that there was a significant and negative difference between digital game addiction and loneliness. A statistically significant difference was found between the levels of Digital Game Addiction (DGA7) and the variable of gender, presence of digital devices, and daily digital game playing status. However, it was concluded that there was a statistically significant difference between the perceived loneliness levels of the participants and their gender, age, income status, and availability of digital devices.

Conclusion: As a result, while the mental training levels of elite boxers differed significantly according to age and being national athlete status, there was no difference according to gender. Mental toughness levels differed significantly according to age categories, but there was no difference according to gender and being national athletic status. There was a positive and significant relationship between the mental training levels of elite boxers and their mental toughness levels. Moreover, it was concluded that the mental training levels of elite boxers were a significant predictor of their mental toughness levels (34%). This result showed that the athletes who want to increase their mental toughness levels should do mental training.
