This study investigates the effects of jackfruit oil extract on adipokine levels (Irisin, Omentin-1), brain-derived neurotrophic factor (BDNF), cognitive performance, and body measurements in healthy young boxers aged 18-25. Participants were randomly assigned to four groups receiving different doses of jackfruit oil extract (0, 100, 200, 300 mg/kg) or no supplement. Saliva samples, cognitive tests, and body measurements were collected at the start of the study and after 30 days to evaluate the outcomes.

This interventional study evaluates the effects of different doses of jackfruit oil extract on healthy young boxers aged 18-25. Participants were randomly assigned to four groups and followed for 30 days.

Saliva samples were collected to measure irisin, omentin-1, and BDNF levels. Cognitive performance was assessed using the Wisconsin Card Sorting Test and the Trail Making Test. Anthropometric parameters including weight, BMI, waist, hip, chest, limb circumferences, and body composition were measured at baseline and on day 30.

Statistical analyses were performed using SPSS version 26. ANOVA, Duncan, and Pearson correlation tests were used to determine significant differences and relationships between variables.

This study is randomized and controlled. Participants receive either one of three doses of jackfruit oil extract or no supplement. The follow-up period is 30 days.

Inclusion Criteria:

• Male boxers aged 18-25 years
• Healthy individuals without any diagnosed chronic disease
