Percentage of participants with above average academic performances by maximum speed reached on 20-m shuttle test.
Scoring above average in math (solid triangle) and Kannada (solid square) was defined by an academic Z-score > 0. The initial speed of the 20-m shuttle was set at 4 km * h-1 (1.11 m * s-1) and increased by 0.5 km * h-1 (0.14 m * s-1) every minute. Academic Z-scores were adjusted for school, gender, and SES. The percentage of participants with above-average performances in math and Kannada increased as the maximum speed reached increased. The number of participants reaching the above maximum speeds is as follows: 7.0 or 7.5 km * hr-1, 22 students; 8.0 or 8.5 km * hr-1, 89 students; 9.0 or 9.5 km * hr-1, 109 students; 10.0 km * hr-1 or greater, 53. Participants reaching maximum speeds of 10.0 km * hr-1 or greater were grouped due to the relatively small number of participants who reached speeds above 10.0 km * hr-1. Values presented are adjusted mean±SE.
