The effect of physical activity on healthy lifestyle, self-esteem and psychological well-being in late adolescents.

A 12-week physical activity program produced statistically significant differences in post-test average scores for all study variables between the intervention and control groups.

• Randomized controlled trial design with 84 university students aged 18-21 in Turkey
• 42 participants in the intervention group and 42 in the control group
• Simple random sampling was used to assign participants to groups
• Statistical significance was set at the 0.05 threshold; all primary outcomes reached p < 0.001

Consistent participation in physical activity among late adolescents led to improved healthy lifestyle behaviors.

• The intervention group received classroom-based education on physical activity and its associated benefits followed by a 12-week physical activity program
• Difference in healthy lifestyle behavior scores between groups was statistically significant (p < 0.001)
• The control group did not receive the physical activity intervention

Participation in the physical activity program was associated with enhanced self-esteem among late adolescents.

• Self-esteem was measured as one of the primary study variables
• Post-test self-esteem scores differed significantly between the intervention and control groups (p < 0.001)
• Participants were university students aged 18-21 enrolled at a university in Turkey

A significant positive association was observed between physical activity participation and elevated psychological well-being levels.

• Psychological well-being was assessed as a primary outcome variable
• The association between physical activity and psychological well-being reached statistical significance (p < 0.001)
• SPSS version 26 was used for data analysis

BMI values among participants in the intervention group showed a favorable change following the physical activity program.

• BMI was tracked as an outcome measure in the intervention group
• The 12-week program duration was associated with the favorable BMI change
• Specific BMI values or effect sizes were not reported in the abstract
