The aim of the study was to assess the comparative effects of football and aerobics dance training participation on students’ attention span. The study was employed randomized parallel group study design. Fifty two participants with age 10-11 years old male students were selected and place randomly in to two training groups. Sample size was determined using G-power 3.1 software. The first group participated in football training and the second group participated in aerobic dance training for 12 week. The data was collected with D2 attention span test at the beginning pre-test and at the end of 12 week training post-test. The collected data was analysed using analysis of Co-variance (ANCOVA). The results showed that both training groups are significantly improving answering correct answer at (P < 0.001) with 34.3% effect size as a result of improving attention. In addition they showed reduced percentage of error making at (P < 0.001) with effect size 61.6% in the post test as compared to pre-test. When we compare the two training groups football trained groups showed significantly higher attention levels compared to aerobic dance trained groups at (p<0.001) with effect size 29%. In conclusion, both football and aerobic dance training are capable of improving attention span in elementary school students. However, football training has higher attention span improvement than aerobic dance training in elementary school students. Therefore, we recommended that school principals, students’ families and different stakeholders should give attention to students sport participation especially in football training to improve their attention span for learning capacity.
