the study aimed to evaluate self-esteem following 12 weeks of intervention and detraining from an archery activity among sedentary youth. The study sample consisted of 34 male youth who were chosen randomly, and allocated into archery and control group. The Rosenberg Self-Esteem Score was used, consisting 10 items to measure merely on self-esteem. The measurement was taken three times; baseline, week 12 and week 24 along the intervention course. The results shown that the self-esteem among the archery group was significantly higher following 12 weeks of intervention compared to baseline. However, at week 24 (after detraining), the score was reduced compared to week 12. The level of self-esteem among control group was similar at baseline, post-intervention and detraining. Archery intervention provides good improvement on self-esteem especially among sedentary youth. Withdrawal from archery intervention leads to reduction of self-esteem score.
